ABSTRACT:
A method for the welding by laser, of two metallic parts having a clearance between them. This method is characterized by a dual laser discharge operation. A first laser discharge, done with a first offset with respect to the lateral face of one part, melts a strip of metal which comes into contact with the metal of the other part. A second laser discharge, done with a second offset, smaller than the first offset, heats the two parts and forms a weld joint.
