Fillet Weld Bead Size Calculator
An engineering tool to determine the minimum required fillet weld leg size for structural steel applications based on the thickness of the parts being joined, as per AWS D1.1 code.
Why is Weld Size Important?
The size of a fillet weld, typically measured by the length of its legs, is a critical design parameter. A weld that is too small will not have the required strength to carry the load, leading to potential failure of the joint. A weld that is excessively large is wasteful in terms of both labor and consumable materials, increasing the project cost and potentially introducing more heat and distortion than necessary. Welding codes like the American Welding Society (AWS) D1.1 provide tables of minimum required fillet weld sizes based on material thickness to ensure structural integrity.
