One pass laser welding method for a T-shaped assembly of metallic workpieces

摘要

Laser welding two- or three-part metallic assembly comprising metal parts arranged in T shape, includes assembling metal parts adjacent to each other, and laser welding the assembly through the outer surface of a T head by two welds made at the same time and parallel to each other and perpendicular to the top surface of the T head such that each of the two welding axes is tangent to one of the surfaces of plates forming the stem of T.
