GETIG 70S2

IDENTIFICATION : ER 70S-2
CLASSIFICATION : AWS A-5.18 : ER 70S-2

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 -300C.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 weld meet 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 550N/mm to meet sub zero Impact requirements down to –30°C. ASTM A 36, A106 A/B/C, A139 etc A516 Grade 70 etc.

Shielding gas : Pure Argon
