Hot cracking reduction in aluminum laser welding |
| abstract |
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. |
