![]() ![]() This flux keeps the atmospheric contamination away. An arc between the electrode and job is the source of the heat and remains buried under a blanket of flux. In the submerged arc welding process the flux-covered electrode is replaced by the granular flux and a bare electrode. The weld metal chemistry is tough to control as the flux alloys will change the characters completely of low alloys steel.Cast iron, Aluminum alloy, Magnesium alloy, and Zinc alloy do not fit into the weldable material by SAW.The quality of the flux may be a cause of concern.The placing of flux will not be possible in irregular edges and may lead to the burning of the edges. The edges of the metal to be welded should clean and fit accurately.The thickness of metal needs is 4.8mm, the lesser thickness will burn the metal.It can weld only in a horizontal direction.Preplacing the flux over the joint to be welded, may not always be possible.To overcome these shortcomings different jigs, fixtures, pointer, light beam, and roller guide may be added to judge and improve the result. He can not judge the quality or any defects. The welding process is not visible to the operator.Suitable for metals like mild steel, medium, and high tensile alloys. The rebuilding of the worn-out parts and wear resistance alloy, tractor rollers, idlers, crane pulleys. No edge preparation of the material under 12 mm thicknessįabrications – The process required in fabrications of pipes, penstocks, boilers, structural shapes, pressure vessels, railroads, rotary kilns, earthmovers, cranes, girders, bridges, locomotives, and under structures of railway coaches.Īutomotive – Aviation, shipbuilding, and nuclear power industries.Safe to the welder, no spatter, no arc flash.Smooth, finely finished, and uniform welding with no spatter. ![]()
