MATERIAL - AMS 6434 STEEL, 180-210 KSI HEAT TREAT WELD REPAIR - FATIGUE TEST OF.

Abstract

To reduce scrap rates and delivery delays, B-58 wing pylon boxes, P/N 4W3306, were being repair welded to build up areas which had been machined undersize. This test program was originated to determine the effect of these repair welds on the tensile, impact, and axial fatigue properties of .090 in AMS 6434 steel used for the assemblies. Butt welds and welds with 50% penetration into the parent metal were examined. Primarily arc weld techniques using Arcoloy 502 coated electrodes were evaluated, although TIG welds were also tested in fatigue. Post welding procedures of stress relieving, shot peening or reheat treatment were evaluated. (Author)
