6500 A18 (ER70S-6) TIG Welding Rod
MasterWeld 6500 is an A18 (ER70S-6) TIG welding rod for mild and medium tensile steels that contains high levels of manganese and silicon to produce high quality welds when used on dirty, oily, or rusty steel.
The high silicon content increases the fluidity of the weld pool, thus creating a smoother bead appearance and resulting in minimal post-weld grinding.
This wire is engineered to provide porosity-free, x-ray quality welds at the highest tensile strength (as welded) of all the plain carbon steel wires.
Applications
- General shop applications with poor fit-up or rusty, oily plates
- Steel castings or forging salvage
- Home projects, tanks, sheet metal, construction work
