Q. Define Heat for electrical resistance welding?
The heat, H for electrical resistance welding is generated by passing a large electrical current ( of the order of 3000 to 100,000 Amps with a voltage between 1 and 25 volts) through two pieces of metal that are touching each other.
H=I2 RT
Where H is the heat generated indicated in joules,
I is the current in root-mean-square amperes, R is the resistance in ohms,.
T is the time (from fraction of a second Tc a few seconds) of current flow through the pieces to be welded.
