Experimental Investigation with Optimization of Spot Welding Parameters on Stainless Steel AISI 304

Opposition spot welding is a welding technique utilizing the standard of non-fusible terminal obstruction welding, where the temperature increases to obtain the dissolving point of the metal, added to a high mechanical strain. Two cathodes of copper not intertwined pack the sheets of metal to be welded against one another and afterward make them go through by an exceptionally impressive current. Our work is separated into two sections. A trial part and a second part on which we will make an improvement of the exploratory outcomes by the design of experiment, to study and see the impact of the boundaries of opposition spot welding, such as current power, welding time, and sheet thickness. In this inquiry, we have quantified and prioritized these last parameters, as well as highlighted their interactions, with the goal of improving the database and making the system more efficient. In addition, the validation of the output responses was carried out in connection with the ultimate strength of the spot welding parameters in order to evaluate the performance of welded joints in terms of their resistance.
