Question

Generally, in welded joints, the maximum size of fillet weld is considered by

• A. adding \(1.5 \text{ mm}\) to thickness of thinner member to be jointed
• B. adding \(3 \text{ mm}\) to thickness of thinner member to be jointed
• C. subtracting \(3 \text{ mm}\) from thickness of thinner member to be jointed
• D. subtracting \(1.5 \text{ mm}\) from thickness of thinner member to be jointed

Hint:

Fillet weld sizing guide parameters: - For square plate edges: \(s_{\max} = t_{\text{thinner}} - 1.5 \text{ mm}\) - For round/rolled sections: \(s_{\max} = \frac{3}{4} \cdot t_{\text{section}}\) This structural margin keeps the edge from melting completely, preserving the base metal geometry.

Answer 1

The Correct Option is D
