The welding technology of ASME SA572 Grade 50 high strength structural steel plates

BBN steel not only supply ASME SA572 Grade 50 high strength structural steel plates, SA572 steel sheets, SA572 Gr.50 steel coil, but also provide SA572 steel plates deep processing such as welding.

The CEV of ASME SA572 Grade 50 high strength structural steel plates is less than  0.4%, so the weldability of SA572 Grade 50 steel is not too bad.

Usually, SA572 Grade 50 steel plates need preheating before welding, and the preheating temperature is 100-150℃. During weldind, the cooling speed need to be controlled strictly. The welding current can be increased and the welding speed can be slowed down in order to slow cooling.

The low hydrogen welding rod for ASME SA572 Grade 50 high strength structural steel plates welding should have strong crack resistance. And Heat treatment is necessary after welding to prevent cold crack of SA572 Grade 50 material
