Basic Fluxes For Submerged Arc Welding

Super Alloys & Metals, established in 1982, is manufacturer of Continuous Welding Consumables. The company manufactures Submerged Arc Wire and Fluxes, and has introduced fully basic fluxes for submerged arc welding (SAW). The Supershield C Series of fully basic fluxes have basicity of around 3. There are 4 fluxes in the current range of fully basic fluxes, viz., Supershield C1, Supershield C4, Supershield C7, and Supershield C8 flux. The fully basic fluxes are neutral in behaviour, yield weld metal with sulphur level lower than 0.005 % and enable superior control on other impurities like O, N, P, Sn, Sb and As. The weld metal also has low hydrogen content. This is the first time that indigenously produced submerged arc fluxes have reached the performance levels of international standard as regards control on sulphur and other impurities. This has been possible because of proper selection and evaluation of raw materials that go into making of flux. The extremely low level of sulphur in combination low levels of oxygen, nitrogen and phosphorous helps to obtain welds with excellent impact toughness from -46°C to -62°C, in combination with indigenously manufactured carbon manganese steel electrodes conforming to AWS class EM12K, EH10K and EH14. The weld metal also satisfies NACE requirements for resistance to hydrogen sulphide stress corrosion cracking. The superior control on impurity levels of P, As, Sb and Sn helps to obtain welds with low X factor, in combination with low alloy steel electrodes conforming to AWS class EB2R and EB3R.
