摘要:
A method of laser welding a workpiece stack-up that includes two or three overlapping aluminum alloy workpieces involves constraining a free end of an overlapping portion of a first aluminum alloy workpiece against movement away from an underlying second aluminum alloy workpiece to counteract the thermally-induced forces that cause out-of-plane deformation of one or more of the aluminum alloy workpieces during laser welding. Such constraint of the free end of the first aluminum alloy workpiece may be accomplished by clamping, spot welding, or any other suitable practice. By constraining the free end of the first aluminum alloy workpiece, and thus inhibiting out-of-plane deformation of the aluminum alloy workpieces when laser welding is practiced in a nearby welding region, the occurrence of hot cracking is minimized or altogether eliminated in the final laser weld joint.

A welding method includes the following steps: (a) determining a martensite tempering temperature of the at least two workpieces based, at least in part, on the chemical composition and microstructure of the woworkpieces; (b) applying sufficient energy to the workpieces to melt the workpieces at a target location, thereby creating a weld pool; (c) determining, via the control module, a target temperature and cooling range of a coolant and cooling range based, at least in part, on the martensite tempering temperature and HAZ width; and (d) cooling the first and second workpieces with the coolant such that a temperature of the workpieces at heat-affected zones is controlled below the martensite tempering temperature in order to minimize softening at the heat-affected zones. The present invention also relates to a welding system for minimizing HAZ softening.
