The welds can be larger, but not smaller unless permitted by the fabrication standard. For intermittent welds, the length of each portion of the weld and the spacing of the welds are separated by a dash (length first, spacing second) and placed to the right of the fillet weld symbol. I believe you are looking for the unwelded spaces between the weld segments. When two parallel members overlap each other it is called this. Ifso, then move upward along this axis to the actual web thickness and use this value to determine proper weld spacing. line. A: Stitch welding, also called intermittent welding or skip welding, involves laying multiple welds with spacing between them rather than having a long, continuous weld. 3. There is a weld at the start of the trajectory, and a space at the end. ) 7 inches (pitch) – 3 inches (length of segment) = 4 inches (spacing in between welds) At times there will be a. 2. weld toe B. 11.
