Abstract : Cast 214, 356-T6, and Almag 35 aluminum plate (3/8 in. thick) were welded to wrought 5456 aluminum alloy plate (3/8 in. thick), using the gas tungsten-arc process. Commercial filler metals 4043, 5183, and 5556 were used. Two beads were deposited on both sides of a double vee joint. It was determined by radiography that the weldments were of excellent quality. No defects were noted, except for slight tungsten inclusions in one weld. All tensile test speciments, with the reinforcements removed, failed in the cast member. The weldments containing Almag 35 casting yeilded the highest tensile properties. Although the joint efficiencies of the 356-T6/5456 weldments were low, the as-welded properties of this combination were approximately equal to the properties of the 214/5456 weldments. The choice of filler metals had little influence on the weldment properties.
