During spot welding of MS sheets 6mm thick, 2000A current is passed for 0.5µs. Sheet interface resistance is 130Ώ and 40% of the heat generated is lost due to radiation and other losses. If 10,000J is the heat required to melt one gram of material melting, determine the size of the nugget formed? Assume the nugget is spherical and density of steel is 7.8 g/c
