Laser welding research improves quality of aluminium-copper joints

Engineers at TWI have developed laser welding procedures that greatly improve the quality of welds made between copper and aluminium.

When welding most dissimilar metal combinations, a key challenge is the different metals’ chemical incompatibility, which typically leads to the formation of brittle intermetallic phases and, consequently, inadequate weld properties.
