What is the minimum length required for intermittent fillet welds?

• A. 1 inch
• B. 1 1/2 inch
• C. 2 inches
• D. 2 1/2 inches

Answer: (B)

The minimum length required for intermittent fillet welds, as specified in the AWS D1.1 Structural Welding Code – Steel, is based on the intended load and the specific application of the weld. A length of 1 1/2 inches is established as a practical standard for ensuring adequate strength and integrity. This length helps to provide a sufficient area for the weld to adequately transfer loads between the joined components while mitigating potential issues such as inadequate penetration or the risk of failure. Choosing a length shorter than 1 1/2 inches may not adequately accommodate the necessary strength or fatigue resistance, particularly in welded joints that may experience dynamic or fluctuating loads. As a result, adherence to this minimum standard is crucial in ensuring that fillet welds maintain their structural integrity over time.
