RG45 is a copper coated low carbon steel rod which is widely used for oxyfuel welding on mild steel. It has good ductility and good machinability. Its typical minimum weld tensile strength is 45 ksi and it conforms to AWS A5.2 R45. RG45 can be used on steel plate, sheet and pipe where high strength is not required.
RG60 is a high strength steel rod which is used for oxyfuel welding on castings, steel plates, structural pipe and shapes with a minimum weld deposit strength of 60 ksi. RG60 conforms to AWS A5.2 R 60.
While these alloys were originally developed and are commonly used for oxyfuel welding, they can be used for TIG welding.
Flux is not needed for either rod but "puddling" of the molten metal will bring any scale or impurities to the surface. Weld on clean base metal to ensure the best results.
