This document discusses mechanical properties of spot welded joints of ferrous alloy under static loads. It outlines objectives to study resistance spot welding of cold rolled mild steel sheets, perform experimental tests in a laboratory including tensile, hardness, and impact tests, numerically model the spot welding, and simulate the tests using Ansys software. The introduction provides background on resistance spot welding and its common applications. The methodology section describes specimen preparation, spot welding process, and planned experiments and numerical modeling/simulation.
