Travel Speed for Target Heat Input
The speed your welder must hold to stay inside a heat-input window.
Welders time a 100 mm run to verify: at 173 mm/min that's ~35 seconds per 100 mm. Slower than the WPS window = hotter than qualified — a code nonconformance, not a style choice.
Formula
Travel Speed for Target Heat Input is a free travel speed welding for welding engineers, fabricators and CWI inspectors — instant, accurate and 100% client-side, with the governing formula and reference shown next to the result so the number can be defended, not just quoted.
About Travel Speed for Target Heat Input
The speed your welder must hold to stay inside a heat-input window. The calculation implements S = η·V·I·60/(1000·HI) (WPS qualification — ASME IX / ISO 15614). Welders time a 100 mm run to verify: at 173 mm/min that's ~35 seconds per 100 mm. Slower than the WPS window = hotter than qualified — a code nonconformance, not a style choice.

Frequently asked questions
What formula does the Travel Speed for Target Heat Input use?+
It computes S = η·V·I·60/(1000·HI), per WPS qualification — ASME IX / ISO 15614. The formula is displayed under the result along with a worked example substituted with your own inputs.
What should I keep in mind when using this calculator?+
Welders time a 100 mm run to verify: at 173 mm/min that's ~35 seconds per 100 mm. Slower than the WPS window = hotter than qualified — a code nonconformance, not a style choice.
Does this follow AWS/IS welding codes?+
Each tool implements the formula from the cited code or handbook (AWS D1.1, IS 800, ISO/EN). Qualified WPS values always govern over any calculator for code work.
Is the Travel Speed for Target Heat Input free to use?+
Yes — completely free, no sign-up, no limits. It runs client-side in your browser, so inputs stay private and results are instant even on slow connections.
