EURO TIG 3 - ER 70S3
Solid copper coated welding wire for welding in gas shielding atmospheres. Slightly higher silicon and manganese alloyed than Euro Tig 2. The higher contains of silicon and manganese increase the yield stress and tensile strength of weld metal. The high silicon content promotes a low sensitivity to surface impurities and contributes to smooth weld. Suitable for welding unalloyed and low alloyed construction steels with tensile strength below 640N/mm2 like boiler plate, fine–grained steels, pipe steels, shipbuilding steels and cast steels.
