spot-welding operation

A resistance spot-welding operation is performed on two pieces of 0.040-in-thick sheet steel (low carbon). The unit melting energy for steel= 150 Btu/in3. Process parameters are: current = 9500 A and time du-ration = 0.17 sec. This results in a weld nugget of diameter = 0.19 in and thickness = 0.060 in. Assume the resistance =100 micro-ohms. Determine (a) the average power density in the interface area defined by the weld nugget, and (b) the proportion of energy generated that went into formation of the weld nugget.
