Laser - heat pipe welding of aluminum alloys with double - cross laser beams

摘要

It is a process for the laser welding of aluminum alloy - workpieces with double laser beams, which, in a cross beam - orientation are arranged, discloses. The method comprises that double laser beams, which has a first laser beam and a second laser beam, together with a welding wire on and along a / r between the aluminum alloy - workpieces produced weld seam is directed. The first laser beam comprises a first longitudinal axis and the second laser beam comprises a second longitudinal axis. After the arrangement in the cross beam - orientation forms a plane in which the first longitudinal axis and the second longitudinal axis of the first and / or of the second laser beam, a line, where it reaches the aluminum alloy - workpieces, which is oriented transversely to the weld seam.
