Aluminum

APPLICATIONS & WELDING

Whether it is wrought or foundry alloys, aluminum alloys share the presence of a layer of oxide called alumina, which is said to be refractory. This characteristic makes it impossible to weld without a prior pickling (chemical, electronic or mechanical) of that oxide.

Inherent problems when welding aluminum and its alloys :

The choice of the filler metal is crucial because it will have influence on : the fluidity, the sensibility to hot cracking, mechanical resistance, joint ductility, corrosion resistance, maintaining service temperature or even the esthetic aspect of the joint.
