Weld Capacity Calculator | CSA S16 Clause 13.3

Calculate fillet weld resistance for structural steel connections per CSA S16 Clause 13.3. Input weld size, length, electrode strength, and loading direction to get factored resistance. The calculator checks both base metal and weld metal failure paths and reports the governing capacity. Full hand-calculation output for engineering documentation.

Reference standard: CSA S16 Cl.13.3

Frequently Asked Questions

What weld types are supported?

Fillet welds per CSA S16 Clause 13.3. The calculator determines capacity based on weld size, length, and electrode classification.

Does it check both failure modes?

Yes. It checks weld metal shear and base metal rupture and reports the governing (lower) resistance.

What electrode classifications are available?

Common electrodes including E49XX (E70XX) series. You can specify the matching electrode ultimate strength directly.
