Welding procedure & parameters
DCEP. Shielding gas: 75–80% Ar + 20–25% CO₂ (CO₂ alone not recommended). Wire dia: 0.9, 1.0, 1.2mm. Preheat per base metal specification.
Typical applications
Widely used for the welding of high tensile steel like IS: 8500 grades 540B & 590B or other equivalent steel .For welding of steel to IS: 2062-11 Gr E410,E450 of all quality ,IS 2002-01 grade III, IS: 1875-04 class IIIA or other equivalent steel .
Storage & handling notes
Mandatory preheat and PWHT per applicable WPS. Ar/CO₂ mix only — CO₂ alone degrades toughness. H4 hydrogen control important.
