So, if you have 3-8 to the right of the fillet weld symbol, it means that the minimum weld length of each segment is 3 inches. Figure 9: Intermittent fillet weld spacing. The contractor can choose whether the weld should be a single- or double-sided weld, asCreating Intermittent Fillet Welds. But we can’t. When depositing intermittent fillet welds, the welding symbol can be interpreted as: a) Weld size is the minimum size. 5. 2. Then s = 2( 1. Intermittent welding is used when either a continuous weld is not necessary, or when a continuous weld threatens the joint by warping. 3. As long as you meet that minimum and satisfy your shear flow, I'd say you'll be fine. Lightweight fillet weld trajectories can be calculated automatically or manually (user-defined). The welding symbol looks fine. The number of required tack welds depends on the joint geometry, length, material thickness, and metal type. Spacing of Intermittent Weld . Creates an intermittent caterpillar. Intermittent welding can save time and money if a long weld is not necessary. In other words, the three criteria the inspector should look at are: 1) The minimum size of the fillet - as specified by the welding symbol.
