Weldability Study of Dissimilar Joints of A 312 TP 316L and A106 Gr.B Steels Using GTAW and SMAW with ER309L, ER309L-15, INCONEL 82 and INCONEL 182 Electrodes

Abstract

In this study, two different pipe welding processes were carried out. In the first welding process, root and hot passes were made using A 312 TP 316L stainless steel and A106 Gr.B carbon steel materials with GTAW (Gas Tungsten Arc Welding) welding method and 2.4 mm ER309L electrode, and 2.5 mm with SMAW (Manual Arc Welding) welding method. Filling and cover passes were performed using the E309L-15 electrode. In the second welding process, A 312 TP 316L stainless steel and A106 Gr.B carbon steel materials were welded with GTAW method using 2.4 mm INCONEL 82 (ER NiCr-3) electrode for root and hot passes, welded with SMAW method with 2.5 mm INCONEL 182 (E NiCrFe-3) electrode for filling and cover passes. As mechanical tests of the obtained welded parts, tensile test, bending test, hardness test and PMI (Positive Material Identification) test were performed, macro images were taken and comparisons were made. As a result, the weldability of stainless and carbon steels with different filler metals and their effects on mechanical properties were examined.
