Welding Heat Input Required

Written by Jerry Ratzlaff on . Posted in Welding Engineering

Welding heat input required, abbreviated as \(H_i \), is how much heat is required to weld.


Welding Heat Input Required formula

\(\large{ H_i = A \; V \; \frac{ 0.06}{ s } }\)   


\(\large{ H_i }\) = welding heat input required

\(\large{ V }\) = arc voltage

\(\large{ A }\) = welding current

\(\large{ s }\) = welding speed
