    Abstract: PROBLEM TO BE SOLVED: To provide a T-shaped assembly laser welding method for preventing defective shape after the welding and reducing the investment in tools. SOLUTION: This method comprises a step of assembling components close to each other, and a step of performing laser beam welding of the assembly via an outer surface of a T-shaped head portion by two welding parts. The welding is performed along the longitudinal direction of the entire assembly by a bifocal welding head 20 having two axes 21 parallel to the surface of a part to form a T-shaped stem portion 10.

    Abstract: 弁ハウジング10とボール20とを有するボール弁を製造する。鏡面対称形状の一対のハウジング半体12、14を単一溶接線で接合する。予め貫通孔と一対の凹所とを付与されたボールを包み込むような態様で、ハウジング半体を溶接接合する。その際、ボールの貫通孔22を溶接線と整合する位置に向けておく。貫通孔の両開放端に整合する位置で、一対の支軸部分を取着するための穴42、50を、それぞれ機械加工によって弁ハウジングに形成する。穴の中心はボール弁の動作中心線上にある。ボールを角度90度だけ回転させて、ボールの貫通孔と弁ハウジングの開口12A、14Aとを整合させ、かつ、ボールの凹所26、28をハウジングの穴に整合させる。次いで、2つの穴に対して一対の支軸部分60、68をそれぞれ装着して2つの凹所にそれぞれ支軸を嵌入させて、一対の支軸部分の周囲をそれぞれ穴の縁部分に溶接接合する。

    Abstract: PURPOSE:To improve yield by providing notches and slits in one of this fitting parts, deforming the weld zone and performs laser welding, and thereby bringing the amount of the fitting gap to zero. CONSTITUTION:Notches and slits are provided at two places near the welding point 11 of a cap 10, a fitting part, to make the side wall 13 of the cap 10 easily plastic deformable from the direction of outer periphery. A sleeve 14 and the cap 10 positioned by an assembling mandrel 16 and a pressing mandrel 17 are moved from direction of the arrow by a pressing plate 15 to deform the side wall 13. After bringing the gap into close contact, the cap is welded by irradiating a laser beam 20 from a laser device 19 to the weld zone of the sleeve 14.
