摘要 |
A method for assembling at least two sheets by laser transparent welding, wherein at least one sheet is coated with a metal protection layer. The method produces punctual deformations on the side of at least one metal sheet, which is to be welded, along a predetermined trajectory thereby forming protuberances; superimposes the metal sheets so that the protuberances project towards the other metal sheet to be welded; holds the sheets tightly against one another by a clamp located on both sides of the predetermined trajectory such that the sheets are in contact with each other at the protuberance; and welds the assembly of metal sheets by a laser beam transparently applied in a discontinuous manner along a predetermined length at each deformation. |
