Choosing the best filler metal for aluminum welding involves taking into account the operating conditions of the finished welded component as well as six important variables that can affect the operating condition.

Filler alloy selection for welding aluminum is an essential part of the development and qualification of a suitable weld procedure specification (WPS). Choosing the most appropriate filler alloy for welding aluminum is based on the operating conditions of the finished welded component and a number of variables.

When selecting a filler alloy for welding aluminum, it’s a good idea to compare the performance of each filler alloy against each of the six variables: ease of welding, strength of the welded joint, ductility, corrosion resistance, sustained-temperature service, and postweld heat treatment.
