Welding Heat Input Calculator
Knowing the heat input (also called welding energy) is extremely important for the quality, safety and efficiency of welding, a process fundamental to industry and to many other applications. Heat input is the amount of energy, in the form of heat, delivered to the material during welding, and understanding its effects on the material and above all on theheat affected zone (HAZ) is essential to producing welded joints of assured quality.
Welding Heat Input Calculator
The heat input formula is:
E = (60 x V x A) / v
Where:
E = heat input (J/mm)
V = welding voltage (V - volts)
A = welding current (A - amperes)
v = travel speed (cm/min)
