Hot Tensile Testing of Dissimilar Welding of SA213TP-347H with SA213 T23

This paper deals with the hot tensile testing of dissimilar metal butt welding of materials SA213TP-347H WITH SA213-T23. These materials are mainly used in the power plants for manufacturing reheater and superheater coils. Specimen will be butt welded in Orbital TIG welding machine having GTAW (Gas Tungsten Arc Welding) Process and shielding with Argon Gas. Dissimilar joint will be welded with each filler wire ER347H and ERNiCr3. Pre heating of base metals are to be done during welding process. Job will be Stress relieved with prescribed temperature and hot tensile properties analysis will be carried out. The other testing methods include hardness test, macro and micro analysis.
