Answer» Explanation: In resistance WELDING of a LAP joint of two mild steel sheets of 1.5 mm thickness, a current of 10000 Amp . is passed for a period of 0.1 SECOND. The effective resistance of the jointis 120 micro OHMS . The density of steel is 0.00786 g/mm3and heat required to melt is 1381 J/g. The joint can be considered as a cylinder of 5 mm DIAMETER and 2 .25 mm height . Calculate the percentageof heat distributed to the surrounding. |
