Recent Developments in the Welding of Light Metals & alloys

THE popularity and increase in use of any metal and its alloys in industry depend largely on their weldability. The post-war development of inert gas shielded are welding processes, which made it possible to obtain consistently and easily, reliable and good welds in the difficult-to-weld light metals and alloys contributed a great deal to the recent phenomenal increase in the use of these materials. This situation has greatly been helped by the latest development of readily weldable alloys, especially aluminium magnesium alloys, which are cold worked and therefore do not suffer the same loss in properties as experienced with some of the other preci-pitation hardening alloys
