INVESTIGATION ON THE WELDING OF HIGH-STRENGTH ALUMINUM ALLOYS.

Abstract

The objective of this research was to develop methods for improving welded joints in high-strength aluminum alloys. Details of work on one phase of this investigation are reported. This phase was concerned with the preparation of ballistic test specimens, and details of the work done on this phase from March 1, 1951, to March 1, 1952 are presented. Several attempts were made to produce crack-free welds in 1-1/2-inch-thick 24S and 75S ballistic test specimens using standard ordnance specifications. Various welding methods and filler metals were tried. None was successful in producing crack-free welds. Crack-free welds could be made, however, by welding the cross weld first. Four 1-1/2-inch-thick H-plates were prepared using this technique. Welding was done with the tungsten-arc process and aluminum - 8 per cent magnesium filler metal.
