This paper describes how the lapped spot welding of copper alloy material for structural components is performed with a YAG laser. Welding conditions and their relation. to mechani-cal characteristics and metal structures is examined. The main results of this paper are summarized as follows : (1) Laser power, amount of defocus and welding strength are deter-mined by using newly introduced equations. (2) Laser powex' is 10-12.5 J, amount of defocus is ±1mm, and the pulse duration is 1-3 ms. With these conditions, a welding strength of over 150 N is obtained. (3) The welded part of the metal structures is dendrite. This clarifies the validity of the metal structures and hardness characteristics under YAG laser operating conditions.
