SMAW – Speciality Welding Electrodes
ISOARC 142: ISOARC 142 is used for joining and cladding armour plate, T1 Steel, Bennox Steel and other similar steels. It is fully heat treatable and resistant to hot-cracking and pressurising.
ISOARC 922: Removing surface defects, grooving cracks for welding, chamfering out of faulty welds, surface cleaning of cast iron of poor weldability.
ISOARC 438: This electrode is easy to use on AC or DC positive polarity. Bead appearance is good, and deposits are non-heat treatable. Hardness is maintained at elevated
temperatures. ISOARC 438 restrikes well. The self releasing slag should be removed after each pass.
ISOARC 454: SOARC 454 is a rutile, coated, hardfacing electrode with good welding properties even when used with AC transformers with a low open circuit voltage. With DC, use positive polarity. The electrode gives a smooth weld deposit; the weld metal is very versatile and is fairly crack resistant. Weld metal is forgeable and malleable when hot. Resistant to tempering up to roughly 500°C.
ISOARC 463: Is extensively used in the mining and mineral industries. Ideal for earth-moving parts, shovels, ore carriers, conveyors, mixer blades, bucket lips and
teeth, crusher mills, chutes, scraper blades and all parts subjected to high abrasive wear. A variety of wear media can be handled – clay, sand, stone and rock.
Hardcraft 55: A rutile coated DC electrode for hard surfacing depositing amartensitic weld having a hardness of approximately 50-55 HRC resistance to moderate impact.
Hardcraft 60: A rutile coated DC electrode specially designed for wear ressistant application. Can withstand impact under relatively abrasive conditions.
