answer all parts
A resistance welding is performed to join two 2-mm thick stainless steel sheets with ten 6-mm diameter spot welds produced concurrently. The resulted weld nugget each has average 3 mm in thickness. Calculate the required welding current and energy consumption for the welding if ten seconds are needed for the whole welding operation. Given that the applied voltage is 10 V. Provide TWO important assumptions in your calculation.
