### Heat Input Calculators - COLLIE WELDING

Heat input is typically given in kJ/mm, so it is necessary to convert the values to standard units, that is:Current (Amps), Voltage (Volts), Travel speed (mm/s) and Thermal efficiency (no units). Those units will give the value of heat input in units of J/mm, so dividing the value by 1000 will give it in units of kJ/mm.

### How To Calculate Heat Input From Welding WELDING

Heat Input = (60 x Amps x Volts) / (1,000 x Travel Speed in in/min) = KJ/in The 60 and the 1,000 are there to turn the final answers into Kilojoules per inch. Example 1:You are welding at 500 inches per minute and 29 volts. How to calculate heat input welding & NDT What is Heat Input in Welding? > Welding InspectorsPosition:Vertical-up progression Highest heat input due to the necessity to weave a suitable profile and the relatively slow Vertical-down Lowest heat input because of the high travel speed. Horizontal-vertical Relatively low heat input welding position because welder cant weave in this

### Heat Input Formula - Definition, Formula And Solved Examples

The heat input formula is given by, [latex]Heat\;Input = \frac {60\times Current \times Volts} {1000\times \left ( distance travelled in /min \right )} [/latex] KJ/in is the unit. The accurate measurement of arc voltage is the difficulty here, but we mostly measure load voltage at the output terminals of the current source.
