Welding Parameters for Aluminum Alloys

With increasing application of aluminum and aluminum alloys, as the most commonly used nonferrous metallic alloys in industrial scales, joining and in particular welding of these alloys remains an important area for mechanical and welding engineers as well as manufacturers to gain broad and comprehensive knowledge of welding parameters of aluminum. This article presents a discussion about weldability and properties of different aluminum alloys before and after welding. To this end, welding of cast and wrought, and heat treatable and non-heat treatable aluminum alloys are assessed in detail in this article. Also, the challenges encountered with aluminum welding, different aluminum welding processes including conventional and solid-state welding techniques are discussed.
