Explain the mechanism of heat generation in Resistance spot welding. Explain the Force (current) vs time diagram.
(a) With the aid a diagram, describe the principle of spot-welding process.
(b)
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
00 TWO important assumptions in your calculation.
