The ability to develop welding procedures for aluminum and aluminum alloys coupled with the ability to weld these alloys is becoming even more important for fabricators. Whether it is a job shop producing different products every day or a firm that specializes in a single product, the ability to fabricate out of aluminum is necessary. […]
Welding aluminum and aluminum alloys does not need to be complicated. However, to successfully weld this metal there are a few things you need to know. First, you need to know how the properties of aluminum affect its weldability. There are four key characteristics of aluminum that make it quite different from carbon steel […]
If you have welded aluminum you know that it behaves considerably different than steel. Other than the strength difference and general appearance, there are four physical characteristics of aluminum that make it weld completely different than steel. These are: High thermal conductivity High solidification shrinkage High hydrogen solubility Oxide coating When welding aluminum it is […]
Should I use 4043 or 5356 aluminum wire for my application? This is a very commonly asked question. The application of these two aluminum alloys has such a big overlap that a lot of times it simply comes down to welder preference, cost or availability. When determining which filler alloy to use the most important […]
