Welding & Metallurgy Calculators
Determine professional welding setups, preheating conditions, steel grades equivalence lookups, hardness scales, and joint geometry.
Fillet Weld Throat & Leg
Convert between throat thickness and leg length for fillet welds. Estimate joint volume, weld weight, and shear load capacity.
Joint Dimensions & Angles
Max design capacity: 615.2 kN (138,299 lbs) of structural force over a 1000mm run using a standard AWS E70 Electrode.
The leg length specifies the weld dimensions along the plate faces, while structural stress checks are conducted on the throat thickness, which represents the shortest path of failure across the weld core.
