resistance spot welding process parameters on the shear-tensile strength of the welded joints of Inconel alloy 625 was investigated. Experimental study using full factorial design of the welding current‚ welding time‚ and electrode force parameters was conducted. In order to identify the influence of each parameter and their interaction a general linear model and a second order model using response surface method was developed. Nonlinear correlation was observed between the welding process parameters

set in stone for me to see the welding lab. After meeting and learning about all the different opportunities there are after attending this school‚ we finally got to meet with Mr. Jezylo and Mr. Paulsen. As soon as I entered the shop I instantly felt at home. The humming of the welding machines‚ the loud crash of metal falling to the floor after being cut‚ and the sparks flying as students are welding were amazing. I could’ve spent forever in there learning about welding and what it takes to become
