What welding rod used to weld A182 gr.f22?

To weld ASTM A182 Grade F22, which is a chromium-molybdenum alloy steel, a suitable welding rod would typically be E9018-B9, which is a low-hydrogen electrode designed for high-strength applications. Alternatively, the E310-16 or E316-16 rods may also be used, depending on the specific requirements of the joint and the desired properties. It’s essential to ensure compatibility with the base material and intended service conditions. Always refer to relevant welding codes and specifications for guidance.
