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.

2021年6月4日 · Maximum heat input (J/min) = (190 X 18 X 60)/80 = 2565 J/min or 2.57 kJ/mm. Here, the unit of travel speed is inches, the heat input will be in Joules/inch or kJ/inch.

Use this handy and easy welding heat input calculator for online heat input calculation for all welding processes.

How to calculate heat input in KJ/mm, when current and voltage given in range, like current 79-81 amp & voltage is given 27-29 volts and travel speed is equal to 135 mm/min.

要获得KJ / in或KJ / mm的结果，请将结果除以1000。 </p><p>示例1：如果焊工需要2分钟才能完成18英寸长的焊接。 他将电压保持在24伏，电流保持在120安培。
