Research of the annealing temperature range influence to the welded joint properties of dissimilar steels

Research of the annealing temperature range influence has been conducted for stress relieving process to the structural properties of welded joint of dissimilar steels. Austenitic steel X 10CrNiTi 18 9 and structural steel St 37-3 have been mutually welded. The welding has been made by SMAW welding method with filler metal, selected by applying Schaeffler diagram. Upon completion of welding procedure, annealing of welded joint has been performed at different temperature ranges as well as quenching. Metalographical testing have been done, the testings of microhardness have been made and also diffusion appearances have been analysed, occurred round fusion line in the part of structural steel.
