This weld is used when the joint has two members coming together to form an intersection of commonly 90 degrees. My two resources (AISC 14th Ed, Manual of Steel construction and AWS D1. You can create continuous or intermittent fillet welds. 25. 8mm per weld where the leg length does not exceed 3/4 plate thickness. I once encountered an inspector that insisted the welds be located within 1/16-inch of the ideal location and the weld lengths couldn’t be more that 1/16-inch longer than specified. 5/16". This can be on one side of the bar only, or where. 2). The versatility and low cost of fillet welds have made them one of the most widely-used joints in the welding industry. 2—This symbol for a square-groove weld includes the length of separation between the edges. 5 states "Fillet weld size shall be as specified in the drawing and represents the minimum weld size. AISC Specification Table J2. 3. 3 – Dimension of welds 5. An intermittent weld is where you make a weld for two, three, or four inches, skip a the same distance you welded and then weld again or skip to the middle of your joint and weld. Looking at EN 1993-1-8, clause 4. Nowadays, automatic welding technology has made it possible to attach longitudinal stiffeners to plates, using intermittent fillet welds in staggered or chained configurations, Fig. bottom. Fillet welds are commonly found as continuous welds but can sometimes be broken or. Chain. With intermittent welds, you can also avoid steel deformation when connecting long elements. and more. D.

I'm looking for guidance on checking/specifying an intermittent fillet weld design based on the Eurocode from people far more familiar with it than I am. 1 Structural Welding Code. The intermittent welding method transforms the full-length continuous weld into multiple short welds to minimize distortion by reducing the total heat input for a welded joint to control welding distortion. 3 paragraph 328. Though a fillet weld may be subjected to direct stresses, it is weaker in shear and therefore the latter is the main design consideration. Each of these factors contributes to the formation of undercut, leading to weakened joints and defects in your welds. 1 shows types of weld spacing configurations that are explored further in this paper. Bevel Angle. g. staggered intermittent weld. 2. Most, but not all fillet welds are of equal legs. The length of intermittent welds is to be measured over the length of the correctly proportioned fillet. 3-50, view A). 2b - If weld length Lw < 100 a, then effective weld length (Lw-eff) = Lw - If Lw < 300 a,.
