Filler alloy selection for welding aluminum is an essential part of the development and qualification of a suitable welding procedure specification. Fig 1. Crack sensitivity of various elements in aluminum. Fig 2. Gas Metal Arc Welding on an aluminum wheel. The use of aluminum as a structural material is fairly recent. In fact, when the Washington Monument was completed in December, , it was capped with a ounce pyramid of pure aluminum, because aluminum was considered to be a precious metal at that time. The problem that impeded the use of aluminum is that it is a reactive metal.

Shielded Metal Arc Welding. SMAW was an important aluminum fabrication process in the past, but as GTAW and GMAW have evolved, it has lost much of its commercial importance. Most companies that supply welding consumables provide aluminum SMAW electrodes.
Negative electrode polarity direct current can be used to weld aluminum by manual and mechanized means. Other arc welding processes include shielded metal arc welding (SMAW), as well as electroslag and electrogas welding (ESW, EGW). SMAW with flux-coated rods has been replaced to a very substantial degree by the GMAW process. 11 Tips for Welding Aluminum in the Shipbuilding Industry By Frank G. Armao, Director, Aluminum Welding Technology The Lincoln Electric Company Aluminum alloys are lightweight and corrosion-resistant in marine environments, making the superior material for use in the shipbuilding industry. For example, if the base material being welded is aluminum, good filler metal options include , , and A / gas metal arc welding (GMAW) wire or gas tungsten arc welding rod can reduce porosity and provide better weldability and increased puddle fluidity, while a product provides greater toughness and strength. This metal is called filler metal. A variety of filler metal types exist: bare electrode wire or rod, covered electrodes, tubular electrode wire, and welding fluxes.
