DESCRIPTION
Copper-coated filler wire has Al, Ti, and Zr as strong deoxidants with Mn and Si content. The wire has very low impurities such as S, P etc and is suitable for applications involving subzero temperatures up to -30°C. This has advantage of semi–killed steel or rusty and contaminated joint area. Smooth flow and gives shiny bead under optimum welding conditions. The deposited weld meet x-ray / radiographic quality code requirement.
