The difference between Jinqiao welding wire 50-6 and 70S-6
Similarly, ER70S-6 is the American Standard, 70 of which means tensile strength, expressed in PSI, while 50S-6 is the domestic standard, and 50 represents tensile strength, expressed in MPA.
Jinqiao welding wire 50-6 and 70S-6 are exactly the same welding wire, but the application grades are different. GB grade: ER50-6, American Standard grade: ER70S-6. 70 of them mean tensile strength, which is expressed by PSI, while 50-6 is domestic standard, and 50 is tensile strength. It is expressed by MPA.Welding wire is used as filler metal or metal wire welding material at the same time as conductive. In gas welding and gas tungsten arc welding, welding wire used as filler metal; in submerged arc welding, electroslag welding and MIG arc welding, welding wire as filler metal, and conductive electrode. The surface of the wire is not coated with anti oxidizing flux.
As ER50-6 is the national standard E70S-6 is American Standard
