Calculate Heat Input for Welding







Formula

The formula to calculate the Heat Input (Hi) is:

\[ Hi = \frac{A \cdot V \cdot s}{L} \]

What is Welding Heat Input?

A welding heat input is the amount of heat required to weld a piece of material at a certain current, voltage, and speed.

Example Calculation

Consider an example where:

Using the formula to calculate the Heat Input:

\[ Hi = \frac{200 \cdot 24 \cdot 60}{10} = 28800 \text{ Joules/inch} \]

This means that the heat input for this example is 28800 Joules/inch.
