In a welding process,i am welding two plates. The welding current is 110A and welding voltage is 20V. Suppose 100% of this electric energy is converted to heat then the heat energy generated is 110x20. i.e., 2.2KJ/sec. Suppose the length of the plate is 2 metres, How can i calculate what is the heat input into the welded joint at each point? I have one more data that welding speed is 1metre/minute.
