Butt weld consumables calculator.

Weld metal, electrode or wire quantity and arc time for single-V butt welds on pipe or plate.

Method

How it's calculated.

The single-V groove cross-section is the bevel triangles plus the root gap plus the cap reinforcement:

A = (t − c)² × tan(α/2) + g × t + ⅔ × w × h

where t is thickness, c the root face, α the included angle, g the root gap, w the cap width (groove width + 3 mm) and h the cap height. Weld metal is A × length × 7 850 kg/m³. Consumable required is weld metal ÷ deposition efficiency. Arc time is weld metal ÷ deposition rate, and welder time is arc time ÷ operator factor.
