The welding of A572 Gr.50 steel plate

A572 Gr.50 steel plate is a kind of high strength low alloy niobium vanadium structural steel in American standard ASTMA572/A572M-07. The welding of A572 Gr.50 steel plate has the tendency to harden, it is easy to produce cold crack, and the toughness of heat affected zone decreases, so A572 Gr.50 steel plate is sensitive to welding heat input.

In order to ensure the A572 Gr.50 steel plate welding quality, the weldability analysis and weldability test of the A572 Gr.50 steel plate were carried out. Selection of appropriate welding methods according to the characteristics of A572 Gr.50 steel plate 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 Gr.50 steel plate. The results are good and fully meet the A572 Gr.50 steel plate technical requirements.

we promise we can offer you the qualified A572 Gr.50 steel plate at the competitive price and rapid delivery time. We can produce A572 Gr.50 steel plate as our customer’s requirement.
