Estimate the tensile strength of a weld joint based on weld size, material, and electrode type.
Start with your values, or try a preset.
Enter Weld Size (inches), Weld Length (inches), Material Tensile Strength (psi), and Electrode Strength Factor in the units shown.
Read Weld Area (square inches), Tensile Strength of Material (pounds), Tensile Strength of Weld (pounds), and Strength Ratio (Weld/Material) in the results panel. Results update as you change the inputs.
Choose a preset to load an example, then adjust the values for your situation.
See the inputs and their calculated results.
