Resistance Spot Welding Machine, Austenitic SS304, Taguchi MethodAbstract
Resistance Spot Welding (RSW) is 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. There are various process parameters like as
electrode pressure, welding power, weld time & so on which affects the weld nugget and its strength. So it is
necessary to optimize the process parameters of resistance spot welding process. From the experimental setup, we
choose Pressure, Power/Welding current, Weld time at three different levels. The approach is based on Taguchi
Method to optimize the resistance spot welding process parameters for effective welding. Austenitic Stainless Steel
304 was selected as work piece material and Taguchi method was used to design the experiments.
