Do you know the welding process of A572 grade 50 steel sheet

A572 grade 50 steel sheet is a kind of high strength low alloy niobium vanadium structural steel in American standard ASTMA572/A572M-07. The welding of A572 grade 50 steel sheet has the tendency to harden, it is easy to produce cold crack, and the toughness of heat affected zone decreases, so A572 grade 50 steel sheet is sensitive to welding heat input.
In order to ensure the A572 grade 50 steel sheet welding quality, the weldability analysis and weldability test of the A572 grade 50 steel sheet were carried out. Selection of appropriate welding methods according to the characteristics of A572 grade 50 steel sheet structure.
Through comparison, the ER80S-G welding wire was determined and the welding process was evaluated. The test results and welding process evaluation have been successfully applied to the welding of practical A572 grade 50 steel sheet. The results are good and fully meet the A572 grade 50 steel sheet technical requirements.
we promise we can offer you the qualified A572 grade 50 steel sheet at the competitive price and rapid delivery time. We can produce A572 grade 50 steel sheet as our customer’s requirement. We keep many A572 grade 50 steel sheet stock in our warehouse. So we welcome to cooperate with you!
