O Calculadora de Resistência de Soldagem estimates the load capacity of fillet and butt welds using weld dimensions, effective length, material strength, and applied load. Review estimated capacity and load utilization to support preliminary weld design and fabrication planning. Results depend on joint geometry, load direction, weld quality, and applicable design standards, so verify calculations with the relevant code or a qualified engineer.

Inputs

1 · What to calculate

Calculation mode
Weld type

2 · Weld geometry

Fillet size entered as

Equal-leg fillet. Throat = 0.707 × leg.

Exclude start/stop craters and returns per your code.

3 · Material & design basis

Classification tensile strength — not an allowable stress.

Capacity is divided by this factor. Blank = 1.00.

4 · Load

AISC 360 factor (1.0 + 0.50 sin1.5θ) for linear fillet weld groups loaded in-plane through the centroid. Off by default (conservative).

The force unit also sets the unit used for the capacity result.
