STEP 0: Pre-Calculation Summary

Formula Used

Heat Transfer Efficiency = Net Heat Supplied/Heat Generated
α = h_Net/H
This formula uses 3 Variables

Variables Used

Heat Transfer Efficiency - Heat transfer efficiency is defined as the ratio of actual heat transfer to the theoretical heat transfer.
Net Heat Supplied - (Measured in Joule) - Net Heat Supplied is the final and total amount of heat transfer in a particular process.
Heat Generated - (Measured in Joule) - Heat Generated is the amount of heat energy produced or transferred from one form to another form.

STEP 1: Convert Input(s) to Base Unit

Net Heat Supplied: 20 Kilojoule --> 20000 Joule (Check conversion here)
Heat Generated: 21.05 Kilojoule --> 21050 Joule (Check conversion here)

Net heat supplied to joint

Go Heat Required per Unit Volume = Heat Transfer Efficiency*Electrode Potential*Electric Current/(Melting Efficiency*Travel Speed of Electrode*Area)

Heat required to Melt Joint

Go Heat Required = Mass*((Specific Heat Capacity at Constant Pressure*Rise in Temperature)+Latent Heat of Fusion)

Total heat generated in resistance welding

Go Heat Generated = Constant to Account for Heat Losses*Input Current^2*Resistance*Time

Rated Duty Cycle given Actual Duty Cycle

Go Rated Duty Cycle = Required Duty Cycle*(Maximum current new add/Rated Current)^2

Required Duty cycle for arc welding

Go Required Duty Cycle = Rated Duty Cycle*(Rated Current/Maximum current new add)^2

Net heat per unit volume available for Arc welding

Go Heat Required per Unit Volume = Input Power/(Travel Speed of Electrode*Area)

Heat Transfer Efficiency

Go Heat Transfer Efficiency = Net Heat Supplied/Heat Generated

Power given Electric Potential Difference and Electric Current

Go Power = Electric Potential Difference*Electric Current

Power given Electric Potential Difference and Resistance

Go Power = (Electric Potential Difference^2)/Resistance

Melting Efficiency

Go Melting Efficiency = Heat Required/Net Heat Supplied

Power given Electric Current and Resistance

Go Power = Electric Current^2*Resistance

Heat Transfer Efficiency Formula

Heat Transfer Efficiency = Net Heat Supplied/Heat Generated
α = h_Net/H

What is heat transfer efficiency?

The Heat transfer efficiency, α formula is defined as the ratio of actual heat gained by joint to the heat generated at electrode.
The actual heat generated at the tip of the electrode and ideally should be available for melting the joint. However, the actual heat utilized by the joint depends upon how this heat is transferred from the tip of the electrode to the joint. Hence a factor of heat transfer efficiency, is to be defined to take into account of any losses in between such that the net heat available at the weld joint.
