1 Answer

Answer :

In this laser welding process, the energy gets into the workpiece only through heat conduction. The welding depth for this process is generally lower than 2 mm. The laser beam melts the materials to be joined along the joint. The melts flow into each other, and the solidified melt connects the materials permanently.
