welding flux removal grinding maching

Welding is classified into two groups: fusion (heat alone) or pressure (heat and pressure) welding. There are three types of fusion welding: electric arc, gas and thermit. Electric arc welding is the most widely used type of fusion welding. It employs an electric arc to melt the base and filler metals. Arc welding types in order of decreasing

    Equipment for Submerged Arc Welding TWI

    Equipment for submerged arc welding. The submerged-arc welding (SAW) process is similar to MIG where the arc is formed between a continuously-fed wire electrode and the workpiece, and the weld is formed by the arc melting the workpiece and the wire. However, in SAW a shielding gas is not required as the layer of flux generates the gases and ...

    Recycling of slag to act as a flux in submerged arc welding

    Aug 01, 2009 Flux used in submerged arc welding is converted into slag during welding which is presently a waste. About 2500 tonnes of flux was consumed in India alone in year of 1982 (Visvanath, 1982) which has risen to more than 10,000 tonnes in the year of 2006 (Honavar, 2006). Such a large quantity of flux, after welding, becomes slag waste and has to ...
