Investigation on the Welding of High-Strength Aluminum Alloys.
Abstract
To determine whether overheating of the small-size test plates used in previous argon-arc welding tests had caused the cracks and porosity observed in the weld metal, an argon-arc weld was made in small 1-inch-thick 3S aluminum test plates to which were welded large pieces of aluminum which served as heat drains, thus simulating welds in large plates. The tensile properties of the recently received 2-inch-thick as-rolled 2S aluminum plate, which will be used in the welding tests, were determined from 0.505-inch-diameter tensile specimens, one transverse to rolling and one longitudinal to rolling, taken from each of two plates. The strength properties of two argon-arc welded joints in 2-inch-thick 2S as-rolled aluminum plate were determined. A carbon-arc welded joint in 2-inch-thick 2S aluminum plate was completed. The room-temperature pressure welding of three aluminum test specimens was attempted.
