Evaluation of Various Techniques for Stress Corrosion Testing Welded Aluminum Alloys

Source

In the development of high-strength, weldable aluminum alloys it is necessary to determine the resistance to stress corrosion cracking of experimental combinations of parent plate and filler alloys. Several types of specimen and methods of loading have been studied to evaluate techniques suitable for rapid screening of alloys and for demonstrating the serviceability of alloys. Stress corrosion tests have been conducted in 3.5 per cent sodium chloride by alternate immersion and in seacoast and industrial atmospheres, comparing beam and tension specimens. The beam specimens were loaded by constant deformation, and tension specimens were loaded both by constant deformation and by constant load. Welded specimens designed to investigate the effect of residual welding stresses upon both butt welds and fillet welds also are included.
