Conservative values based on bare minimum fusion. Multiple factors influence shear strength. Contact AlcoTec to discuss your specific application.

Welded Joint Strength

Typically, the as-welded tensile strength of a groove weld is determined by the condition of the heat-affected zone (HAZ)

of the base material.

Fillet welds are usually not diluted significantly by the base metal. Therefore, the shear strengths of fillet welds are largely

determined by the properties of the filler alloy and not necessarily by the condition of the HAZ of the base.
