How to obtain net heat supplied to the joint?

The Net heat supplied to the joint formula is obtained by considering heat transfer efficiency and melting efficiency of the joint. From the heat released from electrode, all of it cannot be utilized for melting since part of it would be conducted away from the joint by the base metal as reflected in the heat affected zone. The actual heat distributed into the surrounding metal would depend upon the welding process as well as the process parameters including the joint design.
