Weld Travel Speed for a Target Heat Input
Travel speed TS = (60 V I eta)/(1000 HI) to hold a target heat input; travel at or above it to stay at or under the limit. GMAW 24 V, 200 A, eta 0.8, 40 kJ/in -> 5.76 in/min; a 25 kJ/in ceiling forces 9.22 in/min. The qualified WPS governs.
Formula and source
TS = (60 x V x I x eta) / (1000 x HI); check HI = (60 V I eta)/(1000 TS).
