<p><P>PROBLEM TO BE SOLVED: To provide a joint for hybrid welding, by which laser/arc hybrid welding can be performed at high speed. <P>SOLUTION: For the purpose of welding a pair of joining members 11 composed of blanks at the abutting ends by laser/arc hybrid welding in which laser welding and arc welding are continuous, the joint is formed by the pair of abutted welding ends. At the welding ends, there are formed difference-in-level faces 13 situated on the laser irradiation side and welding projections 12 projecting in the abutting direction from the difference-in-level faces 13 and situated opposite from the laser irradiation side. By abutting the welding projections 12 on each other, a welding groove 15 is formed between the oppositely facing difference-in-level faces 13 in the joint 10 for hybrid welding. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
