Notes:
This study performed tensile test using small-size flat specimen and ball indentation test atroom temperature to characterize the local tensile properties of bi-metallic weld joints. The weldspecimens used were fabricated by joining between SA508 Gr.3 ferritic steel and Type 316 stainlesssteel with Alloy 82 buttering on the ferritic steel side and Alloy 82/182 weld metal. The test resultsshowed that yield stress (YS) of weld metal was slightly higher than that of Type 316 and smallerthan that of SA508 Gr.3, and ultimate tensile stress (UTS) of weld metal was similar as those of Type316 and SA508 Gr.3 base metals. Also, the values of YS and UTS of buttering layer (Alloy 82) werenearly same as those of weld metal. Heat-affected-zones (HAZs) showed higher YS and UTS valuescompared to their base metals. Especially, the strengths of SA508 Gr.3 were significantly higher thanthose of surrounding materials. Also, it was known that the ball indentation test reasonably measuredthe local YS and UTS of bi-metallic weld joints
