Aluminum and its alloys are popular metals due to their light weight, corrosion resistance, and weld ability. While they are generally lower in strength, some alloys have mechanical properties similar to steel. Aluminum alloys can be joined by a variety of methods. But they also have some properties that are worth knowing, depending on the method you use.
Therefore, the first step to successful aluminum welding is to become familiar with the various aluminum alloys, their properties, and considerations when selecting filler metal for each alloy.
