Description

本発明は、建築鉄骨構造物の鋼管柱、H形鋼柱、又はH形鋼梁柱梁接合部の溶接方法に関するものである。 The present invention relates to a method for welding a steel pipe column, an H-shaped steel column, or an H-shaped steel beam-column joint of a building steel structure.

建築鉄骨鋼管構造物においては、従来、図1に示すように、小組立で鋼管製短管5Sとダイアフラム1からサイコロ2を製作し、中組立で該サイコロに梁ブラケット4を取り付けるパネルゾーン2の製作をし、大組立で該パネルゾーン2に鋼管シャフト5を取り付けて梁ブラケット付き柱即ち一節柱の製作を行う。即ち、3つの組立工程に分かれて製作を行う。 In a conventional steel frame structure, as shown in FIG. 1, a dice 2 is manufactured from a steel pipe short pipe 5S and a diaphragm 1 by a small assembly, and a beam bracket 4 is attached to the dice by a middle assembly. After manufacture, a steel pipe shaft 5 is attached to the panel zone 2 in a large assembly, and a column with a beam bracket, that is, a one-column column, is manufactured. That is, the production is divided into three assembly steps.

そして、建築鉄骨構造物の角形鋼管又は円形鋼管の柱と、梁フランジと突合せ溶接接合する場合においては、図1及び図2に一例を示すように、通常、梁フランジ端部にレ形開先38を施し、梁フランジ4の端部裏側に裏当金10を密着して宛がい、開先のある側から片側溶接を行う。 In the case of butt welding joining a square steel pipe or a round steel pipe column of a building steel structure and a beam flange, as shown in FIG. 1 and FIG. 38, the backing metal 10 is closely attached to the back side of the end of the beam flange 4, and one-side welding is performed from the side with the groove.

また、図7に示すように、鋼管シャフト5と鋼管短管5S・ダイアフラム1又は中実の一体化サイコロ等から組立溶接とその後の本溶接で製作した梁ブラケット3Bを取り付ける前の工作物を柱体という。また、柱体から梁ブラケット3Bを取り付け鉄骨工場から建設現場への運送単位長さとした工作物を一節という。
図7に示すように、柱体34を製作してから、梁ブラケット3Bを取り付け一節柱の製作を行う方法がある。この方法は柱体工法という。この柱体工法では、柱が長いため柱を水平に寝かして梁ブラケットを柱の上に鉛直に立てるか又は梁ブラケットを柱の横に水平に宛がうことになり、その場合、それぞれ梁ブラケットの柱への取付溶接はそれぞれ横向き溶接か立向き溶接になる。
In addition, as shown in FIG. 7, the workpiece before mounting the beam bracket 3B manufactured by the assembly welding and the subsequent main welding from the steel pipe shaft 5 and the short steel pipe 5S / diaphragm 1 or the solid integrated dice, etc. The body. Further, a work having a beam unit 3B attached from a column body and a transport unit length from a steel factory to a construction site is referred to as a section.
As shown in FIG. 7, there is a method in which the column body 34 is manufactured and then the beam bracket 3 </ b> B is attached to manufacture a one-node column. This method is called a column body method. In this column method, because the column is long, the column is laid down horizontally and the beam bracket is set up vertically on the column, or the beam bracket is horizontally applied to the side of the column. The welding to the column is either horizontal welding or vertical welding.

As shown in FIG. 3, this is a method of performing back wave welding 36 by abutting welding members 35.
As shown in FIG. 4, by butt welding member 5,4 or 1, is a method of performing melt-through bead welding by applying a non-consumable steel backing metal such as copper on the back side with no groove member 4 (Japanese Patent Application No. Hei 8-60098 (Japanese Patent Laid-Open No. 9-225635: Patent Document 1) ).

Japanese Patent Laid-Open No. 9-225635 JP 2001-259830 A JP-A-5-177347

図1及び図2に一例を示すように、通常、柱5と梁3の接合部の梁フランジ4の端部にレ形開先34を施し、梁フランジ4の端部裏側即ち内面に裏当金10を密着して当てて、梁フランジ裏の中央側で仮付溶接8したのち、梁フランジ4とダイアフラム1とを突き合わせて開先のある側から片側溶接を行う方法は、裏当金10をセットする工数が掛かり、その梁フランジ4側とダイアフラム1側の両方にルート部が存在してその両方を初層溶接で十分な溶け込みを行わないとルート部に欠陥が発生しやすいという問題がある。その為、ルート部の間隔即ちギャップを7mm程度という大きな値を用いなければいけない。従って、溶接開先内の溶着量が増加して工数の増大になるという問題がある。また、この従来工法では、梁フランジ4裏面と裏当金10との間及びダイアフラム1と裏当金10との間に隙間が残り、これら隙間の奥に応力集中が働き梁フランジ継手の強度を低減させるという問題がある。 As shown in FIG. 1 and FIG. 2, generally, a ledge groove 34 is applied to the end of the beam flange 4 at the joint between the column 5 and the beam 3, and the back side of the end of the beam flange 4, ie, the inner surface is supported. A method of performing welding on one side from the side having a groove by abutting the gold 10 in close contact and performing tack welding 8 on the center side of the back side of the beam flange and then contacting the beam flange 4 and the diaphragm 1 is as follows. There is a problem that the root part exists on both the beam flange 4 side and the diaphragm 1 side, and the root part is liable to be defective unless both of them are sufficiently melted by the first layer welding. is there. Therefore, a large value of about 7 mm must be used for the distance between the root portions, that is, the gap. Therefore, there is a problem that the amount of welding in the weld groove increases and the number of man-hours increases. Further, in this conventional method, gaps remain between the back surface of the beam flange 4 and the backing metal 10 and between the diaphragm 1 and the backing metal 10, and stress concentration acts behind these gaps to increase the strength of the beam flange joint. There is a problem of reducing.

一方、裏当金を用いないで施工する方法が存在する。
図3に示すように、溶接部材35を突き合わせて、溶接トーチ37から溶接部材35の開先側から溶接アークを出して裏波溶接36を行う片側溶接方法は、裏当金が無いため溶融金属が溶け落ちないように裏波ビードを適正に得る為にはかなり高度な技量と開先精度の確保が必要で、実際には鉄骨材料の精度及び鉄骨部品の製作精度の確保が現状では極めて難しく、裏波溶接が普及していないのが現状である。
On the other hand, there is a method of construction without using backing metal.
As shown in FIG. 3, the one-side welding method in which the welding member 35 is abutted and a welding arc is emitted from the groove side of the welding member 35 from the welding torch 37 to perform the back wave welding 36 has no backing metal, so that the molten metal It is necessary to secure a fairly advanced skill and groove accuracy in order to properly obtain the back bead so that the melt does not melt. Actually, it is extremely difficult to secure the accuracy of the steel material and the manufacturing accuracy of the steel parts. The current situation is that back wave welding is not widespread.

図4に示すように、溶接部材4と5又は1を突き合わせて、部材5の裏側に銅などの非消耗製裏当金10Aを当てて裏波溶接を行う方法は、梁フランジの片側溶接では梁フランジの裏面側及び部材5に相当する柱又は部材1に相当するダイアフラム側に十分な溶接脚長を確保することが困難である。従って、梁フランジ継手の十分な強度を確保することが困難となる場合がある。 As shown in FIG. 4, the method of performing back wave welding by abutting the welding members 4 and 5 or 1 and applying a non-consumable backing metal 10A such as copper to the back side of the member 5 is as follows. It is difficult to ensure a sufficient weld leg length on the back side of the beam flange and the column corresponding to the member 5 or the diaphragm side corresponding to the member 1. Therefore, it may be difficult to ensure sufficient strength of the beam flange joint.

図5に示すように、一方の部材18の端部の裏面に溶接肉盛14して片側溶接する方法は肉盛溶接をする工数が掛かる。
図6に示すように、溶接される角形鋼管5の内側即ち裏側にダイアフラム板1の想定溶接箇所に予め置きビード42をビードオンプレートで置いて、該置きビード42に開先を合わせて角形鋼管5をセットして開先の在る表側から溶接する方法は、置きビード38を置く位置を設定するのが難しく、また、精度の悪い部材5の開先が無い状態で置きビード38の形状を部材5の形状に合わせて正確に確保することは難しいという問題がある。
As shown in FIG. 5, the method of performing welding overlay 14 on the back surface of the end portion of one member 18 and performing one-side welding requires man-hours for overlay welding.
As shown in FIG. 6, the bead 42 is placed in advance on the assumed welded portion of the diaphragm plate 1 on the inner side of the square steel pipe 5 to be welded, that is, the bead-on plate, the groove is aligned with the place bead 42, and the square steel pipe is placed. In the method of setting 5 and welding from the front side where the groove is present, it is difficult to set the position where the placing bead 38 is placed, and the shape of the placing bead 38 is formed without the groove of the member 5 having poor accuracy. There is a problem that it is difficult to ensure accurately according to the shape of the member 5.

課題を解決するためには、安定な裏波溶接を行い、応力集中を防ぎ、溶接開先断面積を減らして溶接工数を減らし、裏当金の取付セット工数を減らし、梁フランジの裏側に十分な脚長を確保し、更に、材料及び製作精度に依存しない施工方法が開発されねばならない。これらの問題別に個々に検討し最適な方法を検討した結果、従来、梁フランジ端部の裏側に裏当金を密着して当てて取り付けていた方法を取り止めて、裏当金を省略し、フランジ裏側の銅当て金を省略し、フランジ裏側の肉盛溶接も省略し、柱体工法で柱を水平に設置し、梁を鉛直又は水平にしてその柱に直角に宛がい該フランジの開先の無い裏側から十分な溶接脚長を確保しながら、水平すみ肉溶接又は立向すみ肉溶接を行えば、該フランジの開先のある表側に安定したビードを形成できることが明らかになった。以後、この梁フランジの裏から溶接して表側に得られた安定なビードを「表波ビード」といい、その安定なビード形成させる方法を「表波溶接方法」又は「表波ビード溶接方法」という。そして、該フランジの開先のある表側にビードを形成させて、しかる後、該梁端部開先のある表側の突合せ溶接を実施することにより、応力集中の少ない強度の高い梁フランジの溶接が得られる。
また、別の表現をすれば、片側レ形開先を取った立て板を横板に直角にセットした後に、立て板の裏側肉盛溶接を兼ねて、立て板の裏側で横板上に置きビードを置いてすみ肉溶接を裏側から行うか、又は、立て板の裏側肉盛溶接と横板の置きビードを兼ねて、立て板のレ形開先の裏側からすみ肉溶接を置いて、開先の表側に表波ビードを形成させる方法を用いる。ここで、溶接部材の裏側から溶接して表側に溶接ビードの波を形成させたビードを「表波ビード」といい、そのビードを形成させる方法を「表波溶接方法」、その溶接を「表波ビード溶接」という。
In order to solve the problem, stable back wave welding is performed, stress concentration is prevented, the welding groove cross-sectional area is reduced, the welding man-hours are reduced, the mounting set man-hour of the backing metal is reduced, and the back side of the beam flange is sufficient. A construction method that secures a long leg length and that does not depend on materials and manufacturing accuracy must be developed. As a result of examining each of these problems individually and examining the optimum method, the conventional method of attaching the backing metal in close contact with the back side of the end of the beam flange was canceled, the backing metal was omitted, and the flange was omitted. Omitting the copper backing on the back side, omitting the overlay welding on the back side of the flange, installing the column horizontally by the column body method, making the beam vertical or horizontal and directing the beam at the right angle to the column It has been clarified that a stable bead can be formed on the front side with the groove groove when horizontal fillet welding or vertical fillet welding is performed while securing a sufficient weld leg length from the back side. Hereinafter, the stable bead obtained by welding from the back of the beam flange to the front side is referred to as “surface wave bead”, and the method of forming the stable bead is “surface wave welding method” or “surface wave bead welding method”. That's it. Then, by forming a bead on the front side of the flange with the groove, and then performing butt welding on the front side of the beam end groove, welding of a high-strength beam flange with less stress concentration is achieved. can get.
In other words, after setting the vertical plate with a single-sided bevel at a right angle to the horizontal plate, it is also placed on the horizontal plate on the reverse side of the vertical plate to serve as overlay welding for the vertical side of the vertical plate. Place fillet and perform fillet welding from the back side, or place fillet weld from the back side of the reed groove on the standing plate to serve as both the backside overlay welding of the standing plate and the horizontal plate placing bead. A method of forming a surface wave bead on the front side of the surface is used. Here, a bead in which a weld bead wave is formed on the front side by welding from the back side of the welded member is referred to as a “front wave bead”. This is called “wave bead welding”.

図8に、水平に置いたH形鋼柱3Cに対し、直角に立てたH形鋼梁フランジ4及びスティフナー25Aのレ形開先加工付き端部38を宛がった状態の外観図を示す。このように、柱及び梁のH形鋼を使用した鉄骨建築では、H形鋼梁3Bのフランジ4を支持するスティフナー25AをH形鋼柱3Cのフランジ4を挟んで設置するのが通例である。次の工程は、スティフナーのレ形開先加工付き端部及びH形鋼梁フランジ端部を水平に置いたH形鋼柱3Cに表波ビード溶接接合することである。図13に、その手順及び実施の形態の詳細を示すが、従来用いていた図2に示すような裏当金10は不要である。しかも、裏側に安定で両部材に対し脚長5mm以上の大きいビードが形成される。このような裏側に大きな安定したビードは銅などの非消耗製裏当金を用いてもなかなか得られない。従って、図3の不安定な裏波溶接の心配や図4の細くて小さい裏波ビードの心配もない。そして、図5の裏面に施工する肉盛溶接の代用にもなるという効果もある。また、本発明では、図8でH形鋼フランジ4が予めH形鋼柱3C上にセットされているので、図6のように、肉盛溶接即ち置きビード42の置く位置を特定する必要もなく、置きビード42を置いた後でセットする部材5の位置を考えて、置きビード42の形状と大きさを調整する必要もない。尚、図6では、角形鋼管柱5が無い状態でダイアフラム1の上に予め置きビード42を施工したのち、角形鋼管柱5を置きビード42部分にセットしてから初層溶接を開先の在る表側から片側溶接で行うが、本発明では、初層溶接はH形鋼梁をセットした状態で開先の無い裏側から表波ビード溶接として実施ののち開先の在る表側で後続の積層を行い、両側溶接で行う。
An embodiment of the invention according to claim 1 will be described.

In addition, a large bead having a leg length of 5 mm or more is formed on the back side with respect to both members. Such a large stable bead on the back side is not easily obtained even when a non-consumable backing metal such as copper is used. Therefore, there is no concern about the unstable backside welding of FIG. 3 and the thin and small backside bead of FIG. And there also exists an effect that it becomes a substitute of the overlay welding constructed | assembled on the back surface of FIG. Further, in the present invention, since the H-shaped steel flange 4 is set in advance on the H-shaped steel column 3C in FIG. 8, it is necessary to specify the position where the overlay welding, that is, the placing bead 42 is placed as shown in FIG. Further, it is not necessary to adjust the shape and size of the placing bead 42 in consideration of the position of the member 5 to be set after placing the placing bead 42. In FIG. 6, after placing the bead 42 in advance on the diaphragm 1 without the square steel pipe column 5, the square steel pipe column 5 is placed and set in the bead 42, and then the first layer welding is performed. In the present invention, the first layer welding is performed as surface wave bead welding from the back side without a groove in the state where the H-shaped steel beam is set, and the subsequent lamination is performed on the front side where the groove exists. Perform by both-side welding.

FIG. 9 shows an external view of the H-shaped steel beam placed horizontally, with the H-shaped steel column flange standing upright and the stiffener end with the groove-shaped groove working. In this case, both the column and the beam are H-shaped steel, and FIG. 8 is an application example in which the positional relationship between the column and the beam is simply switched. The difference is that FIG. 9 is a beam through in contrast to the column through in FIG.

FIG. 10A shows a case where the H-shaped steel base material is installed, and FIG. 10B shows a case where the H-shaped steel is installed on the welded joint. In both cases, the construction conditions are the same as in FIG. 8, but after the horizontal fillet welding of the lower side of the stiffener 25A, the opposite side is welded by reversing the top of the H-section steel. It is necessary to (1) use the rod as a reverse method, (2) use a high current, (3) increase the welding speed, and (4) reduce the arc voltage so that the surface wave bead is sufficiently formed. is there.

請求項1に係る発明の他の実施の形態について説明する。図11に、水平に置いたH形鋼柱3Cと溶接されたダイアフラム1に対し、直角に立てたH形鋼梁フランジ3Cのレ形開先加工付き端部38を宛がった状態の外観図を示す。この場合、ダイアフラム1の厚さは、H形鋼梁3Bのフランジ厚よりも1.25〜2倍程度以上厚くして柱3Cから20mm程度以上突きだしているダイアフラム1とH形鋼柱25とを溶接接合して、柱3Cを水平にした状態にして、そのダイアフラム1の上に柱3Cに対し直角に立てたH形鋼梁3Bを乗せ、そのH形鋼梁3Bのフランジのレ形開先加工付き端部38を宛がったもので、ダイアフラム1の上にH形鋼梁フランジのレ形開先加工付き端部38を宛がう以外は図8と同様であり、H形鋼梁3Bのフランジのレ形開先加工付き端部の接合方法及びその効果も同じである。 Another embodiment of the invention according to claim 1 will be described. FIG. 11 shows an external view of the H-shaped steel column 3C placed horizontally and the diaphragm 1 welded to the end 38 with the shape of the groove-shaped groove of the H-shaped steel beam flange 3C standing at a right angle. The figure is shown. In this case, the thickness of the diaphragm 1 is about 1.25 to 2 times thicker than the flange thickness of the H-shaped steel beam 3B, and the diaphragm 1 and the H-shaped steel column 25 protruding from the column 3C by about 20 mm or more. The welded joint is made so that the column 3C is in a horizontal state, and an H-shaped steel beam 3B standing at a right angle with respect to the column 3C is placed on the diaphragm 1, and the flange shape of the flange of the H-shaped steel beam 3B is placed. This is the same as in FIG. 8 except that the end portion with machining 38 is addressed, and the end portion 38 with the H-shaped steel beam flange is formed on the diaphragm 1. The joining method and the effect of the end portion of the 3B flange with the shape of the groove are also the same.

請求項1に係る発明の他の実施の形態について説明する。図12に、水平に置いたH形鋼柱3Bと溶接された該柱3Cからの突き出しのないダイアフラム1に対し、直角に立てたH形鋼梁フランジ4のレ形開先加工付き端部38を宛がった状態の外観図を示す。この場合、ダイアフラム1の厚さは、H形鋼梁3Bのフランジ厚よりも3〜6mm程度以上厚くして、該柱3Cから突きだしていないダイアフラム1とH形鋼柱3Cとを溶接接合して、該柱3Cを水平にした状態にして、そのダイアフラム1の上に柱3Cに対し直角に立てたH形鋼梁3Bを乗せ、そのH形鋼梁3Bのフランジ4のレ形開先加工付き端部38を宛がったもので、H形鋼柱3Cとダイアフラムを組合せダイアフラム1の上にH形鋼梁フランジのレ形開先加工付き端部38を宛がう以外は図8と同様であり、H形鋼梁3Bのフランジのレ形開先加工付き端部38の接合方法及びその効果も同じである。図12では、ダイアフラム1の高さ位置と柱3Cの高さ位置と柱3Cの溶接7の高さ位置はほぼ同じなので、梁フランジ4の裏側すみ肉溶接及び表側継手溶接において下向き溶接と同様に大電流で溶接施工でき得る条件は、開先の下から横方向に水平に広く存在し溶融金属が下側から支えられることで確保されている。そして、ウエブ9と梁フランジ4との溶接を実施して柱梁接合部の溶接を完了させる。 Another embodiment of the invention according to claim 1 will be described. FIG. 12 shows an end portion 38 of the H-shaped steel beam flange 4 with a beveled groove formed at a right angle with respect to the diaphragm 1 without protruding from the H-shaped steel column 3B and the welded column 3C. The external view of the state which addressed is shown. In this case, the thickness of the diaphragm 1 is about 3 to 6 mm or more thicker than the flange thickness of the H-shaped steel beam 3B, and the diaphragm 1 not protruding from the column 3C and the H-shaped steel column 3C are welded. The column 3C is placed in a horizontal state, and an H-shaped steel beam 3B standing at a right angle to the column 3C is placed on the diaphragm 1, and the flange 4 of the flange 4 of the H-shaped steel beam 3B is attached. Same as FIG. 8 except that the end 38 is addressed and the H-shaped steel column 3C and the diaphragm are combined and the end 38 with the H-shaped steel beam flange is formed on the diaphragm 1. The joining method and the effect of the end portion 38 with the reshape groove processing of the flange of the H-shaped steel beam 3B are the same. In FIG. 12, since the height position of the diaphragm 1, the height position of the column 3C, and the height position of the weld 7 of the column 3C are substantially the same, the back side fillet welding and the front side joint welding of the beam flange 4 are similar to the downward welding. The conditions under which welding can be performed with a large current are ensured by existing horizontally and horizontally from below the groove and supporting the molten metal from below. Then, the web 9 and the beam flange 4 are welded to complete the welding of the column beam joint.

請求項1に係る発明の他の実施の形態について説明する。図13に、建築鉄骨の表波ビード溶接手順を示し、図13(イ)は水平に置いたH形鋼フランジ4に対し、鉛直に立てたH形鋼梁フランジ4又はスティフナー25Aのレ形開先加工付き端部25Aを宛がった状態、又は、水平に置いた鋼管5に対し、水平方向に直角に立てたH形鋼梁フランジ又はスティフナーのレ形開先加工付き端部25Aを宛がった状態、図13(ロ)は開先のない裏側から水平すみ肉溶接又は立向きすみ肉溶接をして開先の中に表波ビード41を形成する状況、図13(ハ)は表波ビード41を形成した初層溶接の上に第2層以降の溶接を行って継手溶接を実施する状況を示す。図13の(イ)の場合の継手開先セット状況は、開先角度が20°〜45°、開先ギャップが0〜8mmで、望むらくは例えば開先角度が35°程度、開先ギャップが2〜4mm程度である。図13の(ロ)では、溶接方法はTIG溶接・炭酸ガス溶接・MAG溶接等を用い、一例として示せば、炭酸ガス溶接を開先の無い裏側から水平すみ肉溶接による表波溶接を実施する場合は、溶接ワイヤ径1.2mmで、溶接電流は200〜400アンペア望むらくは250〜350アンペアを用いる。また、炭酸ガス溶接を開先の無い裏側から立向きすみ肉溶接による表波溶接を実施する場合は、溶接ワイヤ径1.2mmで、溶接電流は150〜350アンペア望むらくは200〜300アンペアを用いる。このようにすれば、開先の在る表側に表波溶接を形成することができ、従来用いていた図2に示すような裏当金10は不要である。しかも、裏側に安定で両部材に対し脚等5mm以上の大きいビードが形成される。このような裏側に大きな安定したビードは銅などの非消耗製裏当金を用いてもなかなか得られない。従って、図3の不安定な裏波溶接の心配や図4の細くて小さい裏波ビードの心配もない。そして、図5の裏面に施工する肉盛溶接の代用にもなるという効果もある。また、本発明では、柱と梁のH形鋼フランジが最初にセットされているので、図6のように、H形鋼フランジのセット前に肉盛溶接即ち置きビード42の置く位置を特定する必要もなく、置きビード42を置いた後でセットする部材5の位置を考えて、置きビード42の形状と大きさを調整する必要もない。尚、図6では、角形鋼管柱5のセットする位置を想定してその角形鋼管5の裏側に相当する位置で、角形鋼管柱5が無い状態でダイアフラム1の上に予め置きビード42を施工したのち、角形鋼管柱5を置きビード42の部分にセットしてから初層溶接を開先の在る表側から片側溶接で行うが、本発明では、初層溶接はH形鋼梁をセットした状態で開先の無い裏側から表波ビード溶接として実施ののち開先の在る表側で後続の積層を行い、両側溶接で行う。本発明では、初層溶接は開先の無い裏側から表波ビード溶接として実施ののち開先の在る表側で後続の積層を行い、両側溶接で行う。即ち、図13(ハ)に示すように、このようにして得られた表波溶接に引き続き、後続のパスで積層を開先の在る表側で、例えば、水平突合せ溶接及びすみ肉溶を実施して継手溶接を完成させる。この場合の溶接電流は、第2層溶接では炭酸ガス溶接で水平突合せ溶接を実施し、溶接ワイヤ径1.2〜1.4mmで、溶接電流は250〜450アンペア望むらくは300〜350アンペアを用いる。これらの条件は一例であり、溶接ワイヤ、溶接技量等により可変である。通常に従来の横向き溶接を実施する場合は、100〜200アンペアであるが、このような安定した表波を形成させ、且つ表側継手溶接において下向き溶接と同様に大電流で溶接施工でき得る条件は、横板即ち水平に置いたH形鋼梁フランジ4又は柱5が開先の下から横方向に水平に広く存在し溶融金属が下側から支えられることである。 Another embodiment of the invention according to claim 1 will be described. FIG. 13 shows the surface wave bead welding procedure for a building steel frame. FIG. 13 (a) shows the horizontal opening of the H-shaped steel flange 4 or the stiffener 25A. In the state where the end portion 25A with the tip is addressed, or with respect to the steel pipe 5 placed horizontally, the end portion 25A with the H-shaped steel beam flange or stiffener of the stiffener standing upright at the right angle in the horizontal direction is addressed. Fig. 13 (b) shows a situation where horizontal fillet welding or vertical fillet welding is performed from the back side without a groove to form a surface wave bead 41 in the groove, Fig. 13 (c) is A situation is shown in which joint welding is performed by welding the second and subsequent layers on the first layer weld on which the surface wave beads 41 are formed. The joint groove setting state in the case of FIG. 13A is that the groove angle is 20 ° to 45 °, the groove gap is 0 to 8 mm, and for example, the groove angle is about 35 °. Is about 2 to 4 mm. In (b) of FIG. 13, TIG welding, carbon dioxide gas welding, MAG welding, or the like is used as the welding method, and as an example, carbon dioxide welding is performed by surface fillet welding by horizontal fillet welding from the back side without a groove. In this case, the welding wire diameter is 1.2 mm, and the welding current is 200 to 400 amps, preferably 250 to 350 amps. Also, when performing surface wave welding by standing fillet welding from the backside where no carbon dioxide is welded, the welding wire diameter is 1.2 mm and the welding current is 150 to 350 amperes, preferably 200 to 300 amperes. Use. In this way, surface wave welding can be formed on the front side where the groove exists, and the backing metal 10 as shown in FIG. In addition, a large bead of 5 mm or more, such as a leg, is formed on both sides with stability. Such a large stable bead on the back side is not easily obtained even when a non-consumable backing metal such as copper is used. Therefore, there is no concern about the unstable backside welding of FIG. 3 and the thin and small backside bead of FIG. And there also exists an effect that it becomes a substitute of the overlay welding constructed | assembled on the back surface of FIG. Further, in the present invention, since the H-shaped steel flange of the column and the beam is set first, as shown in FIG. 6, the position where the build-up welding, that is, the placing bead 42 is set before the setting of the H-shaped steel flange is specified. There is no need to adjust the shape and size of the placing bead 42 in consideration of the position of the member 5 to be set after placing the placing bead 42. In FIG. 6, assuming the position where the square steel pipe column 5 is set, a bead 42 is preliminarily placed on the diaphragm 1 in a position corresponding to the back side of the square steel pipe 5 without the square steel pipe column 5. After that, the square steel pipe column 5 is placed and set on the bead 42, and then the first layer welding is performed by one side welding from the front side where the groove is present. In the present invention, the first layer welding is a state in which an H-shaped steel beam is set. After performing the surface wave bead welding from the back side without the groove, the subsequent lamination is performed on the front side where the groove is present, and then both sides are welded. In the present invention, the first layer welding is performed as a surface wave bead welding from the back side without the groove, and then the subsequent lamination is performed on the front side where the groove is present, and then the both side welding is performed. That is, as shown in FIG. 13C, following the surface wave welding obtained in this way, for example, horizontal butt welding and fillet melting are performed on the front side where the groove is present in the subsequent pass. To complete the joint welding. In this case, the welding current in the second layer welding is horizontal butt welding by carbon dioxide gas welding, the welding wire diameter is 1.2 to 1.4 mm, and the welding current is 250 to 450 amperes, preferably 300 to 350 amperes. Use. These conditions are merely examples, and can be varied depending on the welding wire, welding skill, and the like. Usually, when carrying out the conventional sideways welding, it is 100 to 200 amps, but the conditions under which such a stable surface wave can be formed and welding can be carried out with a large current in the case of front side joint welding as with downward welding are as follows. The horizontal plate, that is, the horizontally placed H-shaped steel beam flange 4 or the column 5 is present horizontally and horizontally from below the groove, and the molten metal is supported from below.
