摘要

•Revealing effect of processing window on laser welding-brazing of Al/ 22MnB5 steel.•Fe2 (Al, Zn)5 and scattered distributed FeZn10 was identified at the interface.•The fracture modes changed with the increase of defocused distance.•Effects of welding thermal cycle on HAZ of aluminum alloys were analyzed.
