摘要
Tailored aluminum blanks, such as structural automotive components, are formed by gas tungsten arc welding a plurality of aluminum or aluminum-alloy sections. Preferably, a backup plate having a shallow longitudinal groove or a plurality of longitudinal grooves and a beveled electrode are employed. A preferred embodiment comprises the use of a multi-torch assembly for initial cleaning and subsequent smoothing of the resulting weld.
