Question

Two 1.2 mm thick sheets of steel are joined by double-sided spot welding using a current of 6000A and current flow time of t = 0.15 sec. The electrodes are 3 mm in diameter and the weld spot

thickness is approximately one third of the total thickness of the metal sheets. Assuming that the
effective resistance in this operation is 200 micro resistance, estimate the heat generated and its distribution in the
weld zone. (Take density of steel = 8600 Kg/m3 and its latent heat capacity, L =1400 J/g)
