Abstract
Large joint areas with fewer passes and minimal
preparation with high deposition rates is possible in submerged
arc welding. Deposition rates approaching 45 kg/h have been
reported this compares to 5 kg/h (max) for shielded metal arc
welding. In general, one kg of flux is consumed for every kg of
weld metal deposited in submerged arc welding.
There are two important parameters in submerged arc
welding, the flux and the wire, that may be supplied separately.
The arc, end of electrode and molten pool remain completely
hidden are invisible being submerged under a blanket of flux.
A general problem that may occur is the absorption of
moisture by the fluxes during storage. The amount of moisture
absorbed being dependent upon the atmospheric conditions and
time of exposure. Sometimes moisturized flux generated during
submerged arc welding is thrown away as a waste.
The study revealed to recycle the moisturized flux.
Moisturized flux has been processed in such a manner that
allows it to be used as a flux. Additionally it is always important
and useful to reduce waste and to move towards “ZERO WASTE
CONCEPTâ€.
