| 摘 要： | Aluminum killed cold rolled steel used for automobiles was welded in this paper by using CO2 laser with wavelength 10.6μm.The experiment shows that high quality of welding can be realized at welding speed of 4500mm/min by optimizing the parameters.The strenth and hardness of laser welded joints for aluminum killed cold rolled steel increased compared to those of the base metal while the formability decreased.Forming limit diagram of joint material indicated that the laser weld seam should avoid the maximum deformation area of automobile parts during the designing period for the position of weld seam.
