T-06Free calculator

Welding hours estimator.

Welder-hours and crew duration from diameter-inches, productivity norms and factors for material, location and repairs.

The productivity and factors are placeholders for planning. Replace them with your own measured norms; they vary widely with schedule, position, process and supervision.

Method

How it's calculated.

Welding hours are estimated from scope (DI) and a productivity norm, adjusted for material, location and repairs:

Shifts = DI × material factor × location factor × (1 + repair %) ÷ (DI per welder per shift)

Welder-hours are shifts × shift length; duration is shifts ÷ welders. The defaults are placeholders, not Redsafe norms: measured productivity depends on schedule, position, process, preheat and PWHT, access, permits and supervision.

Related reading: estimating welding man-hours.

Estimates for planning and education only. Verify against the applicable code edition, manufacturer data and a competent engineer.
