Multiple beam laser welding apparatus

摘要

A laser welding apparatus for use in industrial processing, which is operable to emit laser energy to weld blanks and the like together along a seamline. The emitted laser energy comprises a multiple beam of two or more coherent light sources. The apparatus is adapted to selectively reposition the orientation of the multiple beam relative to the seamline to compensate for gaps between the abutting portions of the workpieces to be joined.
