This seems like just a more refined EXW (Explosion welding) technique, the 'ridge' weld shape is a dead giveaway. EXW has a major drawback though - it's useless

- saulrh 11y agoYep, one of the images at the bottom shows that they're welding flat sheets of metal together by using a capacitor bank to vaporize a foil sheet to provide a plasma blast that smashes the target metals together. So, yes, more controlled explosive welding.
- retbull 11y agoCould it be used in a tac weld situation. Basically they have some long armed machine that lets them tac an aluminium sheet down to a steal frame.

- azernik 11y agoYeah - in their presentation they point out the similarity, and explicitly talk up their achievement as explosive welding at the laboratory scale, without high explosives.
