Effect of Laser Modification Welding on Formation of Aluminum Alloy

Abstract:

Effects of laser modification welding (LMW) on formation of full-penetration weld were studied, which were based on the laser beam welding (LBW) process of 5A02 aluminum alloy. The results indicated that the welding defects (such as undercut, surface depression and so on) could be improved obviously, and the microstructure of joint by LMW could be finer than that of joint only by LBW. Besides, the strength and toughness of joint would also be increased to some extent by LMW after full-penetration LBW. Therefore, the LMW is an effective method in order to strengthen joint of LBW.
