Copper coated filler wire has Al,Ti,and Zr as strong deoxidants with Mn and Si content. This has advantages of semi–killed steels or rusty and contaminated joint area. Smooth flow gives shiny bead under optimum welding conditions. The deposited weld meets x-ray /radiographic quality code requirement.
TYPICAL USES :
For welding of structural, pressure vessels and boilers involving unalloyed and micro alloyed structural steel with specified tensile strength upto 520N/mm to meet sub zero Impact requirements down to - 45°C. ASTM A 36, A106 A/B/C, A139 etc
CORROSION TEST :
Passes corrosion test as per NACE standard TM-01-77 AND TM-02-84, GS-8 Annexure 1 of EIL specification.
