Requirements for welding materials for R-HIC plates
Thread Content
I’m seeking help from experienced forum members: are there any special requirements for welding materials used for Q345R (R-HIC)? Are there any standards that address this?
You need to ask the welding materials factory. . . There are welding materials designed for these R-HIC sheets; they have the same model number, and the grade also includes terms like R-HIC. I’m not sure what the specific differences are. . . The estimated selling price is a bit higher
