Weldability of Materials - Aluminium Alloys - TWI

The 5xxx series alloys, in particular, have excellent weldability. High strength alloys (e.g. 7010 and 7050) and most of the 2xxx series are not recommended for fusion welding because they are prone to liquation and solidification cracking. The technique of Friction Stir Welding is particularly suited to aluminium alloys.
