Abstract

EN10025-6 S550Q is high strength steel classified under quenched and tempered (Q&T) manufacturing technique.S550Q is specially designed and used by us for welded steel structures for the purpose of heavy lifting and lowering. The entire processing techniques like cutting, edge preparation, welding, and bending are of major importance to the consistency of fabricated structure. This study comprises of an introduction to HSS-S550Q and addresses various important variables by practically. The following main factors are taken to consideration heat input during cutting, edge preparation, and welding, cooling cycle, Hydrogen induced cracking (HIC) Stress Relieving (SR) is mandatory after weld fabrication. The first was to establish a need for SR to achieve desirable weldment properties.SR has been reported to have Complementary benefits such as tempering of WM and HAZ regions and allowing the effusion/diffusion of hydrogen away from the weld region. Bend testing of cross-weld samples was used to qualify the ductility of the weldment before and after SR. In addition, impact, tensile and hardness properties, microstructures were quantified before and after SR.
