Laser Beam Welding of Aluminum Alloy Plates LF2 LF21 LD2 and LY12

The presentation is concerned with the weldability of aluminum alloys and the mechanical properties of the weld joints. 1~3 mm thick aluminum alloy plates LF2, LF21, LD2, and LY12 have been successfully laser beam welded autogenously using a transverse flow CO2 laser made by our group in SIOFM rated
