SINGLE-PASS LASER WELDING METHOD OF T-SHAPED ASSEMBLY OF METALLIC PART |
| 摘要 |
<p><P>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. <P>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. <P>COPYRIGHT: (C)2004,JPO</p> |
