What are the main factors contributing to the generation of heat in resistance welding (ideally explain based on equation)

Answer :

Answer:

Q=I^2Rt

Explanation:

The principle of resistance welding is the Joule heating law where the heat Q is generated depending on three basic factors as expressed in the following formula

Q=I^2Rt

I is the current passing through the metal combination

R is the resistance of the base metals and the contact interfaces

t is the duration/time of the current flow.
