Description
本発明は、溶接方法、及び、溶接装置に関する。 The present invention relates to a welding method and a welding apparatus.
建設現場において、鉄筋や鉄骨等の接合にアーク溶接が採用されている。アーク溶接では、溶接対象である鉄筋や鉄骨等の母材側にアースケーブルを接続し、溶接棒側に電圧供給ケーブルを接続し、母材と溶接棒との間に溶接電流（大電流）を流してアークを発生させることにより、母材の溶接部と溶接棒とを溶融して溶接が行われる（例えば、特許文献１参照）。また、ピン部材やボルト等のスタッド材を鉄筋や鉄骨等の母材に立設する場合、例えば、スタッドガンのプラグにスタッド材を装着し、アースケーブルに接続された母材にスタッド材の先端を圧接した状態で、プラグの給電面を介してスタッド材と母材との間に溶接電流を流してアークを発生させることにより溶接する方法、所謂スタッド溶接方法が採用されている（例えば、特許文献２参照）。 At construction sites, arc welding is used for joining reinforcing bars and steel frames. In arc welding, a ground cable is connected to the base material side of the reinforcing bar or steel frame to be welded, a voltage supply cable is connected to the welding rod side, and a welding current (large current) is generated between the base material and the welding rod. By flowing and generating an arc, welding is performed by melting the welded portion of the base metal and the welding rod (see, for example, Patent Document 1). In addition, when a stud material such as a pin member or bolt is erected on a base material such as a reinforcing bar or steel frame, for example, the stud material is attached to a plug of a stud gun and the tip of the stud material is connected to the base material connected to the ground cable. A welding method is used in which a welding current is caused to flow between the stud material and the base material via the power feeding surface of the plug while generating an arc, so-called stud welding method is employed (for example, patents). Reference 2).
上記のようにアークを発生させて溶接する場合、火花の発生は避けられない。また、スタッドガンのプラグによるピン部材の保持力の低下やプラグの汚れ等により、プラグの給電面とピン部材との接触が悪いと、より火花が発生し易くなる。この溶接時に発生する火花が周囲に飛散すると、作業者の火傷や作業現場の火災に繋がり危険である。 When welding is performed by generating an arc as described above, the occurrence of a spark is inevitable. Further, if the contact between the power supply surface of the plug and the pin member is poor due to a decrease in the holding force of the pin member by the plug of the stud gun or contamination of the plug, sparks are more likely to occur. If sparks generated at the time of welding are scattered to the surroundings, it is dangerous because it may lead to burns of the worker and a fire at the work site.
本発明は、このような事情に鑑みてなされたものであり、溶接時に発生する火花の飛散を抑制することを目的とする。 This invention is made | formed in view of such a situation, and it aims at suppressing the scattering of the spark which generate | occur | produces at the time of welding.

このような溶接方法によれば、保持部とピン部材との接触箇所にて発生する火花が、耐火性の弾性部材と保持部と被覆材とで形成される密閉空間内に閉じ込められ、保持部と被覆材との間から火花が飛散してしまうことを抑制できる。

以下、本発明の一実施形態を、図面を参照しながら説明する。図１は、被覆材２１で覆われた建築部材２０にピン部材２２を溶接する比較例の溶接方法を示す図である。図２Ａは、スタッドガン１０のプラグ１２に耐火性シート３１が巻き付けられる様子を示す図であり、図２Ｂは、耐火性シート３１が設けられたスタッドガン１０の端部の側面図であり、図２Ｃは、耐火性シート３１が設けられたスタッドガン１０の端部の断面図である。図３は、被覆材２１で覆われた建築部材２０にピン部材２２を溶接する本実施形態の溶接方法を示す図である。 Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing a welding method of a comparative example in which a pin member 22 is welded to a building member 20 covered with a covering material 21. 2A is a view showing a state in which the fireproof sheet 31 is wound around the plug 12 of the stud gun 10, and FIG. 2B is a side view of the end portion of the stud gun 10 provided with the fireproof sheet 31. 2C is a cross-sectional view of an end portion of the stud gun 10 on which the fireproof sheet 31 is provided. FIG. 3 is a diagram illustrating a welding method according to this embodiment in which the pin member 22 is welded to the building member 20 covered with the covering material 21.
例えば、建物における鉄筋や鉄骨、空調ダクト等の建築部材２０の表面を、耐火断熱材や保温材、防音材等の被覆材２１で覆うことがある。本実施形態では、建築部材２０を覆う被覆材２１にピン部材２２の脚部を差し込み、溶接装置１によりピン部材２２と建築部材２０とを溶接することにより、建築部材２０（母材に相当）に対して被覆材２１を固定する実施形態を例に挙げる。なお、ピン部材２２は、導電性の材料から構成され、例えば、円盤状の頭部に取り付けられた脚部の先端がやり状に尖鋭されたもの等が挙げられる。 For example, the surface of a building member 20 such as a reinforcing bar, steel frame, or air conditioning duct in a building may be covered with a covering material 21 such as a fireproof heat insulating material, a heat insulating material, or a soundproof material. In the present embodiment, the building member 20 (corresponding to the base material) is obtained by inserting the leg portion of the pin member 22 into the covering material 21 covering the building member 20 and welding the pin member 22 and the building member 20 with the welding device 1. An embodiment in which the covering material 21 is fixed to the case will be described as an example. Note that the pin member 22 is made of a conductive material, and examples thereof include a member in which the tip of a leg attached to a disk-shaped head is sharply sharpened.
また、本実施形態では、溶接装置１をコンデンサ放電式の溶接装置とし、溶接装置１は、スタッドガン１０と、電源装置２と、アースクランプ３と、アースケーブル４と、電圧供給ケーブル５と、を有する。アースケーブル４の一端はアースクランプ３に接続され、他端は電源装置２におけるアースに繋がる端子に接続される。電圧供給ケーブル５の一端はスタッドガン１０に接続され、他端は電源装置２における電圧供給回路（コンデンサ）に繋がる端子に接続される。 Moreover, in this embodiment, the welding apparatus 1 is a capacitor discharge type welding apparatus, and the welding apparatus 1 includes a stud gun 10, a power supply device 2, an earth clamp 3, an earth cable 4, a voltage supply cable 5, Have One end of the ground cable 4 is connected to the ground clamp 3, and the other end is connected to a terminal connected to the ground in the power supply device 2. One end of the voltage supply cable 5 is connected to the stud gun 10, and the other end is connected to a terminal connected to a voltage supply circuit (capacitor) in the power supply device 2.
スタッドガン１０は、ガン形状の本体部１１と、ピン部材２２を保持するプラグ１２（保持部に相当）と、本体部１１内から突出した端部がプラグ１２に接続される保持ロッド１３と、図２に示すように、プラグ１２の側面１２ｂに巻き付けられる耐火性シート３１と、耐火性シート３１を固定する結束バンド３２と、を有する。保持ロッド１３は、軸方向に往復移動可能であり、本体部１１内にて不図示のコイルばねに挿通されており、保持ロッド１３が軸方向の後側（本体部１１側）に移動すると、コイルばねにより軸方向の前側（被覆材２１側）に向かう付勢力が保持ロッド１３に掛かる。よって、プラグ１２に保持されたピン部材２２を建築部材２０に圧接することができる。プラグ１２は円柱状の永久磁石であり、軸方向におけるプラグ１２の前側の端面にピン部材２２の頭部が着脱自在に吸着される。また、保持ロッド１３は導電性の材料から構成され、電源装置２から電圧供給ケーブル５により本体部１１内に供給された溶接電流（大電流）が、保持ロッド１３及びプラグ１２を介して、ピン部材２２に供給される。即ち、軸方向におけるプラグ１２の前側の端面１２ａ（図２Ｃ参照）が、ピン部材２２の保持面であり、ピン部材２２への給電面となる。 The stud gun 10 includes a gun-shaped main body 11, a plug 12 (corresponding to a holding portion) that holds the pin member 22, a holding rod 13 whose end protruding from the main body 11 is connected to the plug 12, As shown in FIG. 2, a fireproof sheet 31 wound around the side surface 12 b of the plug 12 and a binding band 32 that fixes the fireproof sheet 31 are provided. The holding rod 13 can reciprocate in the axial direction, is inserted through a coil spring (not shown) in the main body 11, and when the holding rod 13 moves to the rear side in the axial direction (the main body 11 side), The urging force toward the front side in the axial direction (coating material 21 side) is applied to the holding rod 13 by the coil spring. Therefore, the pin member 22 held by the plug 12 can be pressed against the building member 20. The plug 12 is a cylindrical permanent magnet, and the head of the pin member 22 is detachably attracted to the front end face of the plug 12 in the axial direction. The holding rod 13 is made of a conductive material, and a welding current (large current) supplied from the power supply device 2 to the main body 11 by the voltage supply cable 5 is pinned through the holding rod 13 and the plug 12. It is supplied to the member 22. That is, the front end surface 12 a (see FIG. 2C) of the plug 12 in the axial direction is a holding surface of the pin member 22 and a power supply surface to the pin member 22.
そして、溶接時には、図１に示すように、アースクランプ３が建築部材２０に接続され、スタッドガン１０のプラグ１２に吸着されたピン部材２２の先端がコイルばねの付勢力により建築部材２０に圧接された状態で、スタッドガン１０のスイッチ（不図示）がオンされる。そうすると、電源装置２からの溶接電流がピン部材２２の先端と建築部材２０との間に流れてアークが発生し、ピン部材２２と建築部材２０との接触箇所が溶融し、ピン部材２２が建築部材２０に対して立設した状態で溶接される。よって、ピン部材２２により被覆材２１が建築部材２０に固定される。 At the time of welding, as shown in FIG. 1, the earth clamp 3 is connected to the building member 20, and the tip of the pin member 22 adsorbed to the plug 12 of the stud gun 10 is pressed against the building member 20 by the biasing force of the coil spring. In this state, a switch (not shown) of the stud gun 10 is turned on. If it does so, the welding current from the power supply device 2 will flow between the front-end | tip of the pin member 22, and the building member 20, an arc will generate | occur | produce, the contact location of the pin member 22 and the building member 20 will fuse | melt, and the pin member 22 will be built. It welds in the state standing with respect to the member 20. FIG. Therefore, the covering material 21 is fixed to the building member 20 by the pin member 22.
このように、溶接箇所に溶接電流を流してアークを発生させて溶接を行う場合、火花の発生は避けられない。特に、スタッドガン１０のプラグ１２の給電面１２ａが埃や錆等で汚れていたり、プラグ１２の吸着力が低下していたりすると、プラグ１２とピン部材２２とが接触不良となり、プラグ１２とピン部材２２との接触箇所（給電面）において、激しく火花が発生してしまう。そのため、図１に示す比較例の溶接方法のように、プラグ１２とピン部材２２との接触箇所が剥き出しの状態であり、プラグ１２の給電面１２ａと被覆材２１との間に隙間が生じていると、その隙間から溶接時に発生する火花が飛散し、作業者の火傷や作業現場の火災に繋がり危険である。 As described above, when welding is performed by causing a welding current to flow through a welding portion to generate an arc, the occurrence of a spark is inevitable. In particular, if the power supply surface 12a of the plug 12 of the stud gun 10 is dirty with dust, rust, or the like, or if the suction force of the plug 12 is reduced, the contact between the plug 12 and the pin member 22 becomes poor. Sparks are violently generated at the contact point (power supply surface) with the member 22. Therefore, as in the welding method of the comparative example shown in FIG. 1, the contact portion between the plug 12 and the pin member 22 is exposed, and a gap is generated between the power feeding surface 12 a of the plug 12 and the covering material 21. If this occurs, sparks generated during welding will scatter from the gaps, leading to burns for workers and fires at the work site.
そこで、本実施形態の溶接方法では、図２に示すように、ピン部材２２を保持するスタッドガン１０のプラグ１２（給電面１２ａ）と被覆材２１との間を密閉する耐火性シート３１（難燃性又は不燃性のシート）をスタッドガン１０に設けた状態で、プラグ１２に保持されたピン部材２２を被覆材２１内に通し、当該ピン部材２２を建築部材２０に溶接する。なお、耐火性シート３１は、耐火性の弾性部材であり、例えば、スター電器製造株式会社のスパシャッタ（スパッタシート）等を挙げることができる。 Therefore, in the welding method of the present embodiment, as shown in FIG. 2, a fire-resistant sheet 31 (difficult to seal) between the plug 12 (power feeding surface 12 a) of the stud gun 10 that holds the pin member 22 and the covering material 21. The pin member 22 held by the plug 12 is passed through the covering material 21 in a state where the flame retardant or non-flammable sheet is provided on the stud gun 10, and the pin member 22 is welded to the building member 20. The fire-resistant sheet 31 is a fire-resistant elastic member, and examples thereof include a spa shutter (sputter sheet) manufactured by Star Electric Manufacturing Co., Ltd.
本実施形態の溶接方法を具体的に説明すると、まず、図２Ａに示すように、長方形状である耐火性シート３１をプラグ１２の側面１２ｂ（給電面１２ａに交差する面）に一周に亘って巻き付け、結束バンド３２で固定する。その際、図２Ｃに示すように、耐火性シート３１の端部３１ａをプラグ１２の端部（給電面１２ａ）よりも軸方向（給電面１２ａに直交する方向）における被覆材２１の側に突出させる。なお、結束バンド３２で耐火性シート３１を固定するに限らず、例えば、接着剤で固定してもよい。また、プラグ１２と被覆材２１との間を耐火性シート３１で密閉できればよいため、例えば、スタッドガン１０の本体部１１に耐火性シート３１を巻き付けたり、プラグ１２の給電面１２ａ（底面）に耐火性シート３１を設けたりしてもよい。 Specifically, the welding method of the present embodiment will be described. First, as shown in FIG. 2A, a rectangular fireproof sheet 31 is placed over the side surface 12b of the plug 12 (a surface intersecting the power feeding surface 12a) over the entire circumference. It is wound and fixed with a binding band 32. At that time, as shown in FIG. 2C, the end portion 31a of the refractory sheet 31 protrudes toward the covering material 21 in the axial direction (direction perpendicular to the power supply surface 12a) from the end portion (power supply surface 12a) of the plug 12. Let The fireproof sheet 31 is not limited to be fixed by the binding band 32, and may be fixed by an adhesive, for example. Moreover, since it is sufficient that the space between the plug 12 and the covering material 21 can be sealed with the fireproof sheet 31, for example, the fireproof sheet 31 is wound around the body portion 11 of the stud gun 10, or the power supply surface 12 a (bottom surface) of the plug 12 is wound. A fireproof sheet 31 may be provided.
次に、電圧供給ケーブル５によりスタッドガン１０を電源装置２（電圧供給回路）に繋ぎ、アースケーブル４により電源装置２（アース）に繋がれたアースクランプ３を建築部材２０に取り付ける。その後、スタッドガン１０のプラグ１２の側面１２ｂに巻き付けられて中空円筒形状となった耐火性シート３１の中にピン部材２２の頭部を入れて、プラグ１２の給電面１２ａにピン部材２２の頭部を吸着させる。そして、ピン部材２２の脚部を被覆材２１に差し込み、ピン部材２２の先端を被覆材２１の下の建築部材２０に圧接させる。そうすると、耐火性シート３１の端部３１ａはプラグ１２の給電面１２ａよりも被覆材側に突出しており、耐火性シート３１は弾性部材であるため、図３に示すように、耐火性シート３１の端部３１ａが被覆材２１の表面に密着し、プラグ１２と被覆材２１との間を密閉することができる。即ち、耐火性シート３１とプラグ１２の給電面１２ａと被覆材２１とで密閉空間Ａを形成することができる。 Next, the stud gun 10 is connected to the power supply device 2 (voltage supply circuit) by the voltage supply cable 5, and the ground clamp 3 connected to the power supply device 2 (earth) by the ground cable 4 is attached to the building member 20. Thereafter, the head of the pin member 22 is placed in a fireproof sheet 31 wound around the side surface 12b of the plug 12 of the stud gun 10 to form a hollow cylinder, and the head of the pin member 22 is placed on the power feeding surface 12a of the plug 12. Adsorb part. And the leg part of the pin member 22 is inserted in the coating | covering material 21, and the front-end | tip of the pin member 22 is press-contacted to the building member 20 under the coating | covering material 21. FIG. Then, since the end part 31a of the fireproof sheet 31 protrudes to the covering material side from the power feeding surface 12a of the plug 12, and the fireproof sheet 31 is an elastic member, as shown in FIG. The end portion 31a can be in close contact with the surface of the covering material 21, and the plug 12 and the covering material 21 can be sealed. That is, the sealed space A can be formed by the fireproof sheet 31, the power feeding surface 12 a of the plug 12, and the covering material 21.
換言すると、ピン部材２２の先端（端部）が建築部材２０に当接可能であり、且つ、耐火性シート３１の端部３１ａが被覆材２１に密着可能なように、プラグ１２の端部１２ａから被覆材２１側に突出させる耐火性シート３１の端部３１ａの長さを調整する。そうすることで、密閉空間Ａを形成しつつ、ピン部材２２の先端を建築部材２０に確実に溶接することができる。また、耐火性シート３１を弾性部材にすることで、被覆材２１のような平坦でない面にも耐火性シート３１を密着させることができる。また、被覆材２１の剛性が高い場合にも、耐火性シート３１を弾性部材にすることで、耐火性シート３１を被覆材２１に密着させることができる。 In other words, the end 12a of the plug 12 is such that the tip (end) of the pin member 22 can be brought into contact with the building member 20 and the end 31a of the refractory sheet 31 can be in close contact with the covering material 21. The length of the end portion 31a of the fireproof sheet 31 that protrudes toward the covering material 21 is adjusted. By doing so, the tip of the pin member 22 can be reliably welded to the building member 20 while forming the sealed space A. Further, by using the fireproof sheet 31 as an elastic member, the fireproof sheet 31 can be brought into close contact with a non-flat surface such as the covering material 21. Even when the covering material 21 has high rigidity, the fire-resistant sheet 31 can be adhered to the covering material 21 by using the fire-resistant sheet 31 as an elastic member.
そうして、耐火性シート３１の端部３１ａが被覆材２１に密着している状態で、スタッドガン１０のスイッチがオンされると、電源装置２からの溶接電流がピン部材２２の先端と建築部材２０との間に流れてアークが発生し、ピン部材２２が建築部材２０に溶接される。この時、プラグ１２の給電面１２ａとピン部材２２との接触箇所にて発生した火花は、耐火性シート３１とプラグ１２の給電面１２ａと被覆材２１とで形成される密閉空間Ａ内に閉じ込められるため、火花の飛散を抑制することができる。なお、耐火性シート３１に火花が付着しても燃焼の虞がなく安全である。また、密閉空間Ａにより、ピン部材２２の先端と建築部材２０との接触箇所にて発生した火花や溶融金属の飛散も抑制できる。よって、本実施形態の溶接方法によれば、作業者の火傷や作業現場の火災を防止でき、安全に溶接を行うことができ、周囲の養生も簡略化できる。また、既存のスタッドガン１０に対しても、プラグ１２の側面１２ｂに耐火性シート３１を巻き付けるだけであるため、火花の飛散を容易に抑制できる。 Then, when the switch of the stud gun 10 is turned on in a state where the end portion 31a of the fireproof sheet 31 is in close contact with the covering material 21, the welding current from the power supply device 2 is connected to the tip of the pin member 22 and the building. An arc is generated by flowing between the member 20 and the pin member 22 is welded to the building member 20. At this time, the spark generated at the contact point between the power supply surface 12a of the plug 12 and the pin member 22 is confined in the sealed space A formed by the fireproof sheet 31, the power supply surface 12a of the plug 12, and the covering material 21. Therefore, it is possible to suppress the scattering of sparks. In addition, even if a spark adheres to the refractory sheet 31, there is no risk of combustion and it is safe. Moreover, the sealed space A can also suppress the scattering of sparks and molten metal generated at the contact point between the tip of the pin member 22 and the building member 20. Therefore, according to the welding method of the present embodiment, it is possible to prevent burns of workers and fires at the work site, safe welding can be performed, and surrounding curing can be simplified. Moreover, since only the fireproof sheet 31 is wound around the side surface 12b of the plug 12 with respect to the existing stud gun 10, the scattering of sparks can be easily suppressed.
また、ピン部材２２の長さや被覆材２１の厚さに応じて、プラグ１２の端部１２ａから突出させる弾性部材（耐火性シート３１）の長さを変更する必要がある。但し、本実施形態のように耐火性シート３１をプラグ１２の側面１２ｂに巻き付ける場合には、プラグ１２の端部１２ａから突出させる弾性部材（耐火性シート３１）の長さを容易に変更できる。また、図３では、ピン部材２２の頭部がプラグ１２の給電面１２ａより小さい場合を例に挙げているが、ピン部材２２の頭部の方が大きい場合もある。その場合にも、ピン部材２２の頭部の大きさに合わせて、中空円筒形状に巻き付けられる耐火性シート３１の周長を容易に変更できる。つまり、本実施形態のように、耐火性シート３１をプラグ１２の側面１２ｂに巻き付ける方法によれば、ピン部材２２の違いに関係なく、プラグ１２と建築部材２０との間を容易に且つ経済的に密閉できる。 Moreover, it is necessary to change the length of the elastic member (fireproof sheet 31) that protrudes from the end 12a of the plug 12 according to the length of the pin member 22 and the thickness of the covering material 21. However, when the fireproof sheet 31 is wound around the side surface 12b of the plug 12 as in the present embodiment, the length of the elastic member (fireproof sheet 31) that protrudes from the end 12a of the plug 12 can be easily changed. In FIG. 3, the case where the head of the pin member 22 is smaller than the power feeding surface 12 a of the plug 12 is taken as an example, but the head of the pin member 22 may be larger. Also in that case, according to the size of the head of the pin member 22, the circumferential length of the refractory sheet 31 wound in the hollow cylindrical shape can be easily changed. That is, according to the method of winding the refractory sheet 31 around the side surface 12b of the plug 12 as in the present embodiment, the gap between the plug 12 and the building member 20 can be easily and economically irrespective of the difference in the pin member 22. Can be sealed.
以上、上記実施形態は、本発明の理解を容易にするためのものであり、本発明を限定して解釈するためのものではない。本発明は、その趣旨を逸脱することなく、変更、改良され得ると共に、本発明にはその等価物が含まれることはいうまでもない。 As mentioned above, the said embodiment is for making an understanding of this invention easy, and is not for limiting and interpreting this invention. The present invention can be changed and improved without departing from the gist thereof, and it is needless to say that the present invention includes equivalents thereof.
例えば、上記実施形態では、スタッドガン１０のプラグ１２の側面１２ｂに耐火性シート３１を巻き付けるとしているが、これに限らず、例えば、保持部（プラグ１２）と被覆材との間を密閉する耐火性の弾性部材が保持部に一体に形成されている溶接装置でもよい。また、シート状の弾性部材を使用するに限らず、例えば、中空円筒形状の弾性部材で保持部と被覆材との間を密閉してもよい。また、ピン部材を保持する保持部を永久磁石で構成するに限らず、例えば、チャック機構にしてもよい。その場合にも、チャック機構の側面に耐火性シート３１を巻きつけて、耐火性シート３１の端部を被覆材に密着させることで、火花の飛散を抑制することができる。 For example, in the above-described embodiment, the fireproof sheet 31 is wound around the side surface 12b of the plug 12 of the stud gun 10, but not limited to this, for example, a fireproof sheet that seals between the holding portion (plug 12) and the covering material. A welding device in which a flexible elastic member is formed integrally with the holding portion may be used. Moreover, not only using a sheet-like elastic member, but the space between the holding portion and the covering material may be sealed with a hollow cylindrical elastic member, for example. In addition, the holding portion that holds the pin member is not limited to a permanent magnet, and may be a chuck mechanism, for example. Even in that case, it is possible to suppress the scattering of the spark by winding the fireproof sheet 31 around the side surface of the chuck mechanism and bringing the end of the fireproof sheet 31 into close contact with the covering material.
また、上記実施形態では、ピン部材２２の先端を建築部材２０に接触させた状態で電流を流す溶接方法を例に挙げているが、これに限らず、例えば、ソレノイドコイル等により母材からピン部材を持ち上げた状態でスタッドガンのスイッチをオンしてピン部材を母材に打ち付けて、両者が接触した瞬間に溶接電流を流す溶接方法でもよいし、ピン部材を母材に接触させて通電した後にピン部材を母材から離してアークを発生させて、両者を溶融した状態でピン部材を母材に押し付ける溶接方法でもよい。つまり、ピン部材を保持する保持部を有し、溶接時にピン部材と保持部との間に火花が発生する電気溶接装置による溶接方法であれば本発明が有効となる。 Moreover, in the said embodiment, although the welding method which flows an electric current in the state which contacted the building member 20 with the front-end | tip of the pin member 22 being mentioned as an example, it is not restricted to this, For example, it is pinned from a base material with a solenoid coil etc. A welding method may be used in which the stud gun is turned on with the member lifted and the pin member is struck to the base material, and the welding current flows at the moment when the two members contact each other, or the pin member is brought into contact with the base material and energized. A welding method may be used in which the pin member is separated from the base material to generate an arc and the pin member is pressed against the base material in a state where both are melted. That is, the present invention is effective as long as it is a welding method using an electric welding apparatus that has a holding portion that holds the pin member and generates a spark between the pin member and the holding portion during welding.
