Description
Hang Zhang and co-authors fixed in 2024 a cosmetic and structural flaw in magnetic pulse spot welding. The method welds unlike metals by slamming one plate into another with a magnetic field focused through a shaped tool. Welds worked, but the center of each spot bulged badly, spoiling flatness. The team proposed two cures and tested them on aluminum-to-steel plate pairs.
One cure opens a hole at the flyer plate's center; the other pre-bends the flyer before firing. Studies mapped how voltage, gap, and tool hole size drive the bulge. Both cures removed it, and the holed plate also lowered the energy needed for a sound weld. Cross-sections showed a wavy bonded interface with strong joints. The authors say both fixes extend to other metal pairs. Flat spots widen the method's industrial reach.
