Oerlikon Carborod Galva description: CARBOROD GALVA is a copper coated G2Ti/ER70S-2 type solid TIG welding rod. Suitable for use mainly with Ar shielding gas. CARBOROD GALVA is a microalloyed steel rod, triple-deoxidised with Ti, Al and Zr, used to weld C-Mn and low-alloyed steels with light contamination or oxides on the surface, and for welding of galvanised steels with a tensile strength of 580 MPa, because of better fusion characteristics compared to standard unalloyed rods. Good low temperature toughness.
