There are several ways of calculating the energy put into a weld. The most common approach to calculating the heat for non-waveform controlled welding is to use the welding current, voltage and travel speed.
We just need to put formula. Heat Input welding (H.I.) = Total Energy (KJ)/ Weld Bead length = 560 KJ/ 500mm = 1.12 KJ/mm = 1120KJ/mm. You can use our heat input calculator & above explained heat input formula for welding for calculating heat input
Welding Heat Input formula (H.I.) = ɳ*AE Welding Heat Input Equation/ Heat Input formula in KJ/mm = VI*60/T.S*1000 Heat input units : J/mm & KJ/mm Where AE is arc energy in J/mm ɳ is the thermal efficiency of the process which has no units and is dimensionless. Thermal efficiency for the different arc welding process are tabulated below
Ensure that you input the values correctly to obtain accurate results. Calculate the heat input: Once you have entered the values, the calculator will perform the necessary calculations and provide the heat input in J/mm. Take note of this value for further analysis and adjustment of welding parameters.
(ii) Heat input for instantaneous power measured in Joules (J) = [Power (J) * Arc Time (S)] / Weld Bead Length (mm) 2. Volume of weld Deposit: As per ASME section IX instead of heat input we can be calculate the volume of weld metal deposited per unit of length of weld for each process.
