Magnetic pulse welding

Magnetic pulse welding (MPW) is a solid state welding process that uses magnetic forces to weld two workpieces together. The welding mechanism is most similar to that of explosion welding. Magnetic pulse welding started in the early 1970s, when the automotive industry began to use solid state welding.

The primary advantage of using magnetic pulse welding is that the formation of brittle intermetallic phases is avoided, allowing the joining of metals which cannot be effectively joined by fusion welding. Additionally, the process is nearly instantaneous and does not require shielding gas or other welding consumables.
