Calculate travel speed in IPM or mm/s from weld length and time. Compare to typical ranges for your process.
24 ÷ (93/60) = 24 ÷ 1.55 = 15.5 IPM — within typical GMAW spray transfer range (12–30 IPM). ✓
12 ÷ 0.75 min = 16 IPM — solid GMAW setting for structural steel in flat position.
150 ÷ 68 = 2.21 mm/s (8.7 IPM) — typical for GTAW root passes on pipe (range 2–10 IPM). ✓
Most MIG welding runs 10–20 IPM depending on thickness and wire size. Stick welding is slower, typically 3–10 IPM. GTAW is 2–8 IPM for most applications. Experienced welders on structural plate often run 15–20 IPM with GMAW spray transfer.
Divide the total weld length (inches) by the time it took (minutes). If you timed in seconds, divide length by (seconds ÷ 60). A 24-inch weld completed in 1 minute 33 seconds = 24 ÷ 1.55 = 15.5 IPM.
Yes — travel speed is a direct component of the heat input formula. Slower travel = higher heat input per inch, which affects HAZ grain structure, distortion, and toughness. See the Heat Input Calculator for the full calculation.
