MANUAL AND REPAIR WELDING OF CHEMICALLY MILLED 2014-T6 ALUMINUM SHEETING,

Abstract

A 2 inch wide land 0.100 in. thick, will fully retain the weld heat-affected zone of repaired welds (based on hardness data). Parent metal properties are only slightly affected by weld heat on repairs of 1.5 inch lands. Values of 59,000 psi can be expected with 90 percent confidence for repaired 1.5 inch lands. If 95 and 99 percent confidence is required, expected values for repaired 1.5 inch lands are 57,800 and 55,400 psi. If land widths of 1.625 inches and above are used, parent metal strength can be expected for manual welds followed by repair welds.
