during spot welding used to be analyzed. 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

Optimization of process parameters for Resistance Spot

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. Resistance spot welding joints of AISI 316L austenitic Sep 01, 2014 · Austenitic stainless steel sheet grade 316L (UNS 31603), with a thickness of 1 mm and chemical composition given in Table 1 was used as the base metal.

Spot Welding - an overview ScienceDirect Topics

Spot Welding. Spot welding is the type of resistance welding when the thermoelectric heat is generated, sequentially, at a (usually large) number of isolated points spots, where the mating surfaces are pressed together by an external force during the whole welding process. From:Comprehensive Structural Integrity, 2003. Related terms: Stainless Steels Welding Guide - Lincoln Electricwelded by several welding processes including the arc welding processes, resistance welding, electron and laser beam welding, friction welding and brazing. For any of these processes, joint surfaces and any filler metal must be clean. The coefficient of thermal expansion for the austenitic types is 50% greater than that of carbon steel and Upset Resistance Welding of Carbon Steel to Austenitic Sep 09, 2016 · Effects of welding current (at the range of 2-4 kA) on the microstructure and mechanical properties of upset resistance welds of AISI-1035 carbon steel to AISI-304L austenitic stainless steel rods were investigated. The results showed that the joint strength first increased by raising the welding current up to 3 kA and then decreased beyond it.
