What are welding wires for 20G and 15CrMO?
20G belongs to carbon steel, 15CRMO belongs to heat-resisting steel, should use welding wire ER55-B2TIG-R30 for 1.25%Cr-0.5%Mo and other heat-resistant steel, such as 15CrMo, P11, P12, no state and industry standards, Shanghai power repair plant and other enterprises have its enterprise standard Q/FAAX-31, equivalent to GB/T8110 ER55-B2.
In case of non fusion argon arc welding, it is recommended to use J50 welding wire.
20G belongs to the 15CRMO belongs to carbon steel, heat-resistant steel, welding wire should be used ER55-B2, TIG-R30 for 1.25%Cr-0.5%Mo heat-resistant steel, such as 15CrMo, P11, P12, no national and industry standard, Shanghai electric power equipment factory and other enterprises have the enterprise standard Q/FAAX-31, equivalent to GB/T8110 ER55-B2.Welding: welding, can also be written as "welding" or welding, melt, is two or more than two kinds of material (homogeneous or heterogeneous) by heating and pressurizing, or both, so that the two parts produce atomic binding processing and connection mode. Welding is widely used, both for metals and for metals.
