In view of the problems like incomplete penetration caused by the traditional MAG welding, laser-MAG hybrid welding of 12 mm thick corrosion resistance steel was studied by using the SMA490BW as the research object, which was the material of high speed train bogie. By comparing weld formation, residual stress, microstructure of 12 mm thick corrosion resistance steel welding joints welded by MAG welding and laser-MAG hybrid welding, the following results can be get. The residual stress value in atmospheric corrosion resistant steel SMA490BW welding joint of laser-MAG hybrid welding was smaller than that of MAG welding; the weld appearance quality of hybrid welding was better than that of MAG welding, and the weld microstructure of hybrid welding was much more uniform and fine; the hardness value of the weld zone welded by hybrid welding was higher than that of MAG welding, but the width of heat affect zone was smaller than that of MAG welding.
