Aluminum alloy welding by using a high power direct diode laser
Source abstract
Abstract
Aluminum alloys are the focus of increasing attention from the automobile industry because of their light weight, high formability, and easy recyclability. In this report, a 4 kW high power direct diode laser was used to examine the weldability of aluminum alloys of AA5022 and AA6016. A heat conduction welding type bead shape was produced with a very smooth bead surface. Full penetration butt welding was possible up to a welding speed of 12 m/min for 1 mm thick AA5022 and 6 m/min for 1 mm thick AA6016. Welding phenomena were observed with a high speed video camera. Very quiet welding phenomena were observed, with no spattering or laser plasma formation.
