  • Why are fluxes used in submerged arc welding?

    They are especially useful for single pass high speed welding such as fillet welding of web to flange girder joints. The basic fluxes fill much the same role in submerged arc welding as basic coatings do in manual metal arc welding.See all results for this questionWhat kind of equipment is needed for submerged arc welding?The basic equipment necessary for Submerged Arc welding includes a power source; controller/interface; wire drive motor; torch; wire straightener; cables; and a flux hopper. The reliability of power sources is essential in SAW, since they are often subjected to 100 percent duty cycles at high welding currents.See all results for this questionWhat are the parameters of arc welding in saw?The welding parameters in SAW arc voltage, welding current, travel speed, stickout, torch angle, wire diameter, wire feed speed and polarity all influence the shape and quality of the weld and productivity, so its important to be aware of their individual and combined influence.See all results for this question
