pdf resistance spot welding of sus316l austenitic
This experimental study is based on an investigation of the effect and optimization of welding parameters on the tensile shear strength in the Resistance Spot Welding (RSW) process. The experimental studies were conducted under varying electrode forces, welding currents, and welding times. The settings of welding parameters were determined by using the Taguchi experimental design of L18 (PDF) EFFECTS OF ELECTRODE DEFORMATION ON 304 A poor weld macrograph (Oblique electrode force) 265 Effects of Electrode Deformation on 304 Austenitic Stainless Steel Weld Geometry of Resistance Spot Welding Figure 8. A very poor weld macrograph (Heavy expulsion) Effect of Electrode Dressing Initally the nugget geometry was formed according to the truncated type electrodes as shown in Figure 9.

Meh (PDF) Study of Spot Welding of Austenitic Stainless Steel Resistance Spot welding process is most applicable in the industrial fields of manufacture and maintenance (car industry, aerospace and nuclear sectors, electronic and electric industries). Murat et al.  have studied on the resistance spot weldability of galvanized interstitial free steel sheets with austenitic stainless steel sheets. FAILURE MODE AND STRENGTH ANALYSES OF Joint failure, e.g. resistance spot weld (RSW) joint failure, was identified as one of the key failure types when a vehicle crash occurs 9 . Failure mode of resistance spot welds is indicator of weld quality. Two major types of spot weld failure are pull-out and interfacial fracture 9,10 . The aim of this paper
This paper presents a comparative study on the fatigue strength of resistance spot-welded unequal and equal sheet thickness austenitic stainless steel. Lap joints of 3.0-1.0 mm and 1.0-1.0 mm thick austenitic stainless steel were made using the same resistance spot welding schedule with current, weld time and electrode force of 4.7 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 joints of AISI 316L austenitic In this paper, we aim to optimize welding parameters namely welding current and time in resistance spot welding (RSW) of the austenitic stainless steel sheets grade AISI 316L. Afterward, effect of optimum welding parameters on the resistance spot welding properties and microstructure of AISI 316L austenitic stainless steel sheets has been
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. Fig. 1a shows dimension of the specimen which was welded by RSW method (linear overlapping of plates). Fig. 1b demonstrates geometric morphology of the nugget and Fig. 1c depicts selected resistance spot welded 316L austenitic What is Spot Welding? (A Complete Welding Process Guide)A form of resistance welding, spot welding is one of the oldest welding processes whereby two or more sheets of metal are welded together without the use of any filler material. The process involves applying pressure and heat to the weld area using shaped alloy copper electrodes which convey an electrical current through the weld pieces.Resistance spot welding joints of AISI 316L austenitic The optimisation of welding parameters namely welding current and time in resistance spot welding of austenitic stainless steel sheets of grade AISI 316L was done by Danial Kianersi et al.
