EVALUATION OF THE MECHANICAL PROPERTIES OF AS WELDED AGED INCONEL X.
Abstract
Tests were conducted to evaluate the room temperature properties of .050 inch thick Inconel X repair welded in the aged condition. Material was manual T.I.G. butt welded in both the mill annealed and the aged conditions. The material welded in the annealed condition was then aged. The face of the welds were longitudinally slotted .050 wide to a depth one-half the thickness of the weld bead. The slots were filled with weld metal to simulate a weld repair on aged material. Tensile specimens were machined from the weldments and tensile tests conducted to compare the mechanical properties of the repair welded material to the properties obtained from material aged after welding to represent an 'as welded' condition, and from unwelded, aged material. Results show that repairs effected on welds resulted in substantial strength reduction in the weld heat affected zone. Ductility of the repair welded material was also considerably reduced. (Author)
