RECLAMATION OF SLAG AS FLUX CONSUMPTION BY THE EFFECT OF WELDING PARAMETERS IN SAW

Jay Chaudhary,Jogendra Kumar


Submerged arc welding (SAW) is a common arc welding process where the total welding cost includes the cost of the flux consumed during welding. It has high deposition rate and productivityFlux used in submerged arc welding contributes a major part towards welding cost In the present work Slag generated during submerged arc welding has been recycled by mixing variousPercentages of crushed slag in virgin flux to use in subsequent runs. A 30 % slag flux mixture has been used. The influence of using flux-slag mixture on weld chemistry and appearance has been investigatedThe response surface methodology (RSM) technique has been used to the calculate runThe results indicate that the use of such a mixture in submerged arc welding does not effect the chemistry and appearance of the weld metal.
