Weld nugget formation in resistance spot welding of ASS 347 grade austenitic stainless steel of equal and unequal thicknesses and in addition of ASS 347 austenitic chrome steel to ASS 1045 carbon steel was once studied. Finite element model took under Experimental studies in weld nugget strength of resistance May 18, 2017 · Resistance spot welding is one of the oldest and effective joining processes which generates heat by sending an electrical current through the sheets at controlled time and pressure to develop a joint at the interface of the sheets. As the demand for spot welding is drastically increased due to the increase in manufacturing of biomedical and automotive components, a detailed study on the Guidelines For Resistance Spot Welding - Millerany welding. Remove all flammables within 35 ft (10.7 m) of the weld. If this is not possible, tightly cover them with approved covers. Do not spot weld where flying sparks can strike flammable material. Protect yourself and others from flying sparks and hot metal. Be alert that welding sparks can easily go through small cracks and
Resistance Spot Welding (RSW) is widely utilized for joining purpose especially in automobile industry due to its robustness, speed, flexibility and low cost operation. It depends on the resistance of the base metal and the amount of current flowing to produce the heat necessary to make the spot weld.
