Studies and Experimental Research on Correlation Thermal

The paper presents the analysis and experimental research that is performed to correlate the welding procedure with hardness in HAZ (Heat Affected Zone) and toughness of welded joints of austenitic stainless steel X6CrNiTi18-10,used to build cryogenic tanks to liquid nitrogen storage.For this were welded a sample by MIG welding process.In a first step it was estimated the hardness of HAZ Stainless Steels Welding Guide - Lincoln Electricand toughen the weld.3.3 AUSTENITIC STAINLESS STEEL The austenitic stainless steels contain 16-26% Cr,8-24% Ni + Mn,up to 0.40% C and small amounts of a few other elements such as Mo,Ti,Nb (Cb) and Ta.The balance between the Cr and Ni + Mn is normally adjusted to provide a microstructure of 90-100% austenite.These alloysSensor Requirements for Detection and Characterization of These locations are often found in weld zones and the heat-affected zones (HAZ) of welded joints.Ideally,these cracks could be repaired by traditional fusion welding more techniques,but the highly localized heat input of the repair welding may introduce additional high tensile residual stress and could increase the risk for future SCCs.
