以下、上記摩擦攪拌接合装置を用いて両被接合材(1)を摩擦攪拌接合する方法について説明する。 The following describes how to friction stir welding the two members to be joined to (1) by using the friction stir welding apparatus.

まず、図3に示すように、各保持具(3)の両構成部材(7)を開き、両構成部材(7)間に被接合材(1)を配置した後両構成部材(7)を閉じ、その先端部どうしを固定する。 First, as shown in FIG. 3, open both components (7) of the holder (3), both components after placing the welded material (1) between two components (7) (7) It closed, to fix the tip each other. ついで、おねじ軸(9)を回すことにより保持具(3)の径方向内方に移動させ、押さえ部材(11)の接触部材(11b)を被接合材(1)の外周面に押し付けることによって、各被接合材(1)を各保持具(3)に固定する。 Then, the retainer by turning the male screw shaft (9) is moved radially inward of (3), is pressed against the contact member of the pressing member (11) and (11b) on the outer circumferential surface of the joining material (1) by fixing each of the joining material (1) to each holder (3). ついで、両被接合材(1)の端面どうしを当接させるとともに、各保持具(3)を各ローラ対(13)の2つの支持ローラ(12)に回転自在に支持させる。 Then, it causes abutting the end face each other of the two members to be joined (1), rotatably is supported the retainers (3) to the two support rollers of each roller pair (13) (12). ついで、押圧装置(16)の押圧本体(17)を下降させ、各押圧装置(16)の両押さえローラ(19)(21)により各保持具(3)を各ローラ対(13)の支持ローラ(12)に向かって押圧する(図1および図2参照)。 Then, to lower the pressing body (17) of the pressing device (16), the support rollers of both pressing rollers of the pressing device (16) (19) each roller pairs each holder (3) by (21) (13) presses against the (12) (see FIGS. 1 and 2).

この状態で、摩擦攪拌接合用工具(2)の回転子(4)を回転させながら、両被接合材(1)の当接部分における周方向の1箇所に、プローブ(5)を埋入するとともに、工具(2)における小径部(4a)とプローブ(5)との間の肩部(4b)を、被接合材(1)の外周面に押し付ける(図4参照)。 In this state, while rotating the rotor (4) of the friction stir welding tool (2), in the circumferential direction of the one point in the contact portions of both members to be joined (1), and implanted probe (5) together, the shoulder between the small diameter portion of the tool (2) and (4a) and the probe (5) to (4b), pressed against the outer circumferential surface of the joining material (1) (see FIG. 4). 肩部(4b)の押し付けにより、接合開始時および接合途中に生じることのある軟化部の肉の飛散を防止して良好な接合状態を得ることができるとともに、両被接合材(1)と肩部(4b)との摺動によって摩擦熱をさらに発生させてプローブ(5)と両被接合材(1)との接触部およびその近傍の軟化を促進することができ、しかも接合部の表面へのバリ等の凹凸の発生を防止することができる。 By pressing shoulder of (4b), to prevent scattering of softening portions of meat that may occur during joining the start and bonding it is possible to obtain a good bonding state, both the bonding material (1) Shoulder part by sliding between (4b) further generates frictional heat can promote softening of the contact portion and the vicinity thereof in the probe (5) and both members to be joined (1), yet the surface of the joint it is possible to prevent the occurrence of unevenness of burrs.

ついで、両被接合材(1)を図示しない適当な手段により中心線の周りに回転させることによって、プローブ(5)を上記当接部分の周方向に移動させる。 Then, by rotating about the center line by suitable means (not shown) both the bonded material (1), moves the probe (5) in the circumferential direction of the contact portion. このとき、摩擦攪拌接合用工具(2)を移動することにより、および/または両被接合材(1)をその横断面内において移動させることにより、プローブ(5)を両被接合材(1)の断面の外形に沿って上記当接部分の周方向に移動させる。 At this time, by moving the friction stir welding tool (2), and / or by moving in both the bonded material (1) in its horizontal cross-section, a probe (5) both members to be joined (1) along the contour of the cross-section is moved in the circumferential direction of the contact portion. すると、プローブ(5)の回転により発生する摩擦熱と、両被接合材(1)と肩部(4b)との摺動により発生する摩擦熱とによって、上記当接部分の近傍において両被接合材(1)の母材となる金属は軟化するとともに、この軟化部がプローブ(5)の回転力を受けて攪拌混合され、さらにこの軟化部がプローブ(5)通過溝を埋めるように塑性流動した後、摩擦熱を急速に失って冷却固化するという現象が、プローブ(5)の移動に伴って繰り返されることにより、両被接合材(1)どうしが接合されていく。 Then, the frictional heat generated by rotation of the probe (5), and by the frictional heat generated by sliding between the shoulder (4b) both members to be joined (1), both to be joined in the vicinity of the contact portion together with the metal as a base material of wood (1) is softened, the softened portion is agitated and mixed by receiving a rotational force of the probe (5), further plastic flow softening unit so as to fill the probe (5) passing through the groove after, phenomenon rapidly losing cooled and solidified the frictional heat, by repeated with the movement of the probe (5), and if both the welded material (1) is gradually joined. このとき、摩擦攪拌接合用工具(2)を適当な手段により上下動させることにより、プローブ(5)の被接合材(1)への埋入深さを一定に保つとともに、肩部(4b)の被接合材(1)への押し付け力を一定に保つようにする。 At this time, by vertically moving the friction stir welding tool (2) appropriate means, the probe with kept constant implantation depth into the welded material (1) to (5), the shoulder (4b) to maintain a constant pressing force to the welded material (1).

ここで、図5に示すように、摩擦攪拌接合用工具(2)を移動することにより、および/または両被接合材(1)をその横断面内において移動させることにより、摩擦攪拌接合用工具(2)のプローブ(5)の軸線(X)と、当該軸線(X)が被接合材(1)の外周面と交わる点での接線における接合方向前方の部分(Y)とのなす角度θを90度<θ≦105度に保つようにする。 Here, as shown in FIG. 5, by moving the friction stir welding tool (2), and / or by moving in both the bonded material (1) in its horizontal cross-section, the friction stir welding tool the axis of the probe (5) of (2) (X), the angle between the joining direction forward section in the tangential at the point of intersection with the outer peripheral surface of the axis (X) is welded material (1) (Y) theta the to maintain the 90 ° <theta ≦ 105 degrees.

また、押圧装置(16)の圧縮コイルばね(24)の変形量を検出し、この変形量に基づいて押圧本体(17)を上下動させ、両押さえローラ(19)(21)による保持具(3)の押圧力を制御する。 Further, to detect the amount of deformation of the compression coil spring (24) of the pressing device (16), is moved up and down the pressing body (17) on the basis of the amount of deformation, the two pressing rollers (19) the holder by (21) ( controlling the pressing force of 3).

そして、プローブ(5)が上記当接部分の全周にわたって移動して埋入位置に戻ったときに両被接合材(1)どうしが全周にわたって接合される。 Then, the probe (5) is both welded material when returning to move implantation position over the entire circumference of the contact portion (1) How to are joined over the entire circumference. ついで、プローブ(5)が埋入位置に戻った後、好ましくは埋入位置を通過した後に、両被接合材(1)の当接部分に配置した当て部材(図示略)までプローブ(5)を移動させ、ここでプローブ(5)を引き抜く。 Then, after returning to the implantation position probe (5), preferably after passing through the implantation position, to contact member disposed in abutting portions of both members to be joined (1) (not shown) the probe (5) moving, where withdrawing the probe (5). こうして、両被接合材(1)が摩擦攪拌接合される。 Thus, both the welded material (1) is friction stir welding.

上記において、両被接合材(1)がそれぞれ保持具(3)に保持されているが、これに限定されるものではなく、一方の被接合材(1)の長さが短い場合、短い被接合材(1)は図示しないチャックなどにより保持し、他方の長い被接合材(1)だけを保持具(3)により保持しておいてもよい。 In the above, if both the welded material (1) is held in each holder (3), it is not limited thereto, a short length of one of the joining material (1), short-be bonding material (1) it is held by such a chuck, not shown, may be held by the other long welded material (1) by a holding device (3).

次に、摩擦攪拌接合用工具(2)のプローブ(5)の軸線(X)と、当該軸線(X)が被接合材(1)の外周面と交わる点での接線における接合方向前方の部分(Y)とのなす角度θを、90度<θ≦105度に保つことが好ましいことを確認するために行った試験について述べる。 Next, the axis of the probe (5) of the friction stir welding tool (2) and (X), joining forward portion in the tangential at the point of intersection with the outer peripheral surface of the axis (X) is welded material (1) (Y) and the angle theta of, describe tests conducted to confirm that it is preferable to keep the 90-degree <theta ≦ 105 degrees.

被接合材(1)として、JIS A6061−T6からなる横断面だ円形の筒状のものを用意した。 As the welded material (1), but cross-section consisting of JIS A6061-T6 were prepared a circular cylindrical. 被接合材(1)の断面の外形は長径150mm、短径105mmのだ円形であり、肉厚は3mmである。 Outline of the cross section of the welded material (1) is the major axis 150 mm, a short diameter 105mm Noda circular, the thickness is 3 mm. また、摩擦攪拌接合用工具(2)として、回転子(4)の小径部(4a)外径:12mm、プローブ(5)径:4mm、プローブ(5)長:3mmのものを用意した。 Further, as a friction stir welding tool (2), the small diameter portion of the rotor (4) (4a) outside diameter: 12 mm, probe (5) diameter: 4 mm, probe (5) Length: were prepared 3mm ones. そして、上述した摩擦攪拌接合装置を使用し、摩擦攪拌接合用工具(2)のプローブ(5)の軸線(X)と、当該軸線(X)が被接合材(1)の外周面と交わる点での接線における接合方向前方の部分(Y)とのなす角度θを種々変更して、2つの被接合材(1)を上述した方法により摩擦攪拌接合した。 Then, using the friction stir welding apparatus described above, the axis of the probe (5) of the friction stir welding tool (2) and (X), that the axis (X) intersects the outer peripheral surface of the bonding material (1) with various changes the angle θ of the welding direction forward section (Y) in the tangential with, and friction stir welding by the method described above the two members to be joined (1).

ついで、被接合材(1)どうしの接合部から試験片を作成して引張試験を行い、接合部の引張強度を測定した。 Then, subjected to a tensile test and a test piece from the junction of and what the welded material (1) to measure the tensile strength of the joint. また、接合前の材料から試験片を作成して引張試験を行い、母材の引張強度を測定した。 Moreover, subjected to a tensile test and a test piece from the bonding before the material was measured tensile strength of the base material. ついで、継手効率(%)=(接合部の引張強度/母材の引張強度)×100という式により継手効率を求めた。 Then, determine the coupling efficiency the expression joint efficiency (%) = (tensile strength of tensile strength / base material of the joint) × 100.

各角度θにおける継手効率を表1に示す。 Table 1 shows the joint efficiency at each angle theta.

表1中、○は継手効率が75%以上の場合を示し、×は継手効率が75%未満の場合を示す。 In Table 1, ○ the joint efficiency represents not less than 75%, × shows the case of a joint efficiency is less than 75%.

表1に示す結果から、上記角度θが90度<θ≦105の場合に、接合部の強度の著しい低下を防止することが可能になることが分かる。 From the results shown in Table 1, the angle theta is in the case of 90 degrees <theta ≦ 105, it can be seen that it is possible to prevent a significant reduction in strength of the joint.

図6は、断面の外形が多角形状、ここでは五角形状の被接合材(30)どうしを摩擦攪拌接合する方法を示す。 6, the outer shape of the cross section polygonal shape, here illustrating a method of friction stir welding was what pentagonal welded material (30). なお、被接合材(30)の外周面の稜線部に丸みがつけられている。 Note that rounded the ridge portion of the outer peripheral surface of the bonding material (30). 断面の外形が五角形状の被接合材(30)どうしの摩擦攪拌接合も、断面の外形がだ円形である被接合材(1)の場合と全く同様に行うことが可能である。 Outer shape pentagonal welded material of the cross-section (30) if friction stir welding also can be performed in exactly the same manner as that of the welded material which is circular but has the outer shape of the cross section (1). この場合にも、接合の際には、摩擦攪拌接合用工具(2)を移動することにより、および/または両被接合材(30)をその横断面内において移動させることにより、摩擦攪拌接合用工具(2)のプローブ(5)の軸線(X)と、当該軸線(X)が被接合材(30)の外周面と交わる点での接線における接合方向前方の部分(Y)とのなす角度θを90度<θ≦105度に保つようにする。 In this case, the time of bonding, by moving the friction stir welding tool (2), and / or both the welded material (30) by moving in the transverse cross-section, friction stir welding angle between the axis of the probe (5) of the tool (2) and (X), the axis (X) is the joining direction forward section in the tangential at the point of intersection with the outer peripheral surface of the bonding material (30) (Y) the theta to maintain the 90 ° <theta ≦ 105 degrees. また、押圧装置(16)の圧縮コイルばね(24)の変形量を検出し、この変形量に基づいて押圧本体(17)を上下動させ、両押さえローラ(19)(21)による保持具(3)の押圧力を制御する。 Further, to detect the amount of deformation of the compression coil spring (24) of the pressing device (16), is moved up and down the pressing body (17) on the basis of the amount of deformation, the two pressing rollers (19) the holder by (21) ( controlling the pressing force of 3).
