Assume that two 2-mm thick cast-iron sheets are being spot-welded at a current of 5000 A and over a current flow time of 0.1 second by means of electrodes 2.5 mm in diameter. Estimate the heat generated and its distribution in the weld zone if the effective resistance in the operation is 2002 Only provide your final answers herg Approximate Specific Energies Required to Malta Unit Volume of commonly Welded Metals Specific energy Material Aluminum and its alloys 2.9 Cast irons 7.8 Copper Broue (900-105) Magnesium Nickel Steels 9.1-10.3 9.3-9.6 Stainless steels Titanium
