Identification :
ER 70S-2
Classification :
AWS/SFA-5.18: ER 70S-2
Approved By : EIL at CPCL site Chennai and BPCL site Mahul, Mumbai
Charecteristics :
Copper coated filler wire having 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 and gives shiny bead under optimum welding conditions .The deposited welds meet x-ray /radiographic quality code requirement
