Zusammenfassung: | To provide a joining device and a joining method of a metal member capable of restraining an increase in an upset quantity while securing high joining strength.SOLUTION: A metal member joining device 1 comprises a base 10, a welding head 11, a pressurization rod 12, a deformation suppression unit 17 and a welding current supply part 18. The welding head 11 descends downward in the Z direction in a state of holding a first metal member 100 composed of carbon steel. The deformation suppression unit 17 comprises deformation suppression heads 13 and 14, and adds a fastening load inward in the radial direction from its outer peripheral part to a second metal member 101 composed of an Al alloy. Pressing of arrows Aand Aby the deformation suppression unit 17 is synchronously executed with pressurization of an arrow A, and outward deformation in the radial direction of the annular second metal member 101 is restrained thereby.SELECTED DRAWING: Figure 1
【課題】高い接合強度を確保しながら、アップセット量の増大を抑制することができる金属部材の接合装置及び接合方法を提供する。【解決手段】金属部材接合装置1は、ベース10と、溶接ヘッド11と、加圧ロッド12と、変形抑制ユニット17と、溶接電流供給部18と、を備える。溶接ヘッド11は、炭素鋼からなる第1金属部材100を保持した状態でZ方向下向きに下降する。変形抑制ユニット17は、変形抑制ヘッド13,14を有し、Al合金からなる第2金属部材101に対して、その外周部から径方向内向きに締め付け荷重を付加する。変形抑制ユニット17による矢印A2,A3の押圧は、矢印A1の加圧と同期してなされ、これにより環状の第2金属部材101の径方向外向きの変形が抑制される。【選択図】図1 |
