ER70S-2 is a copper-coated manganese-silicon wire for welding of mild steel and 490 N/mm2 grade steel. Adding on the slight aluminum(Al), titanium(Ti) and zirconium(Zr) metallic elements, the weldability is great on all-position pipe welding of root pass layer. It also has a great impact value at -30?C. APPLICATIONS: Suitable for pressure vessels, petro and chemical industry for root pass welding. NOTE ON USAGE: 1. Use pure Ar as shielding gas and DC polarity. 2. Clean the surface of base metal to prevent contamination.
