Laser Beam Welding Method Used for Assembling Two Metal Parts

摘要

The process enables partitioned box members to be manufactured, fixing them together from the outside of these box members. Two successive inclined shots of a laser beam (8A, 8B) are used, these intersecting in the region of the upper surface (1B) of the workpiece (1) forming the top of the assembly. The two laser-welding axes (8A, 8B) cut through two upper corners (2C) of the workpiece (2) forming the leg of the T. The welding device is placed on the outside of the box member, that is to say on the side of the upper surface (1B) of the top (1) of the T. Application to the manufacture of the arms of the outer channel of a turbojet.
