If a weld has a 3 mm gap in a fillet weld, by how many millimeters should the fillet weld size be increased?

Explanation:
When a fillet weld must bridge a gap, you must compensate by increasing the weld size by the exact amount of that gap. The goal is to fill the space so the weld achieves the intended throat and strength. If the gap is 3 mm, you increase the fillet weld size by 3 mm to maintain the designed throat thickness. This ensures the joint transfers loads as planned and isn’t weakened by the unfilled space.
