22.2 Joint and Weld Terminology 22.2.3 Fillet Welds Fillet welds have a triangular cross-section and are applied to the surface of the materials they join. The strength of a welded connection is dependent on the weld metal strength and the area of weld that resists the load. Weld metal strength is a measure of the capacity of the Calculating weld stress under bending load using Shigley Apr 11, 2007 · The .707 is to get the throat length, by multiplying this figure with the leg length of the weld, so imagine a weld with a leg length of say .5" the throat length would be.707 * .5" which is the w you base your stresses on. Actually the .707 is the cosine of 45 degrees as usually all fillet welds are assumed to be at 45 degrees. regards desertfox

Step 4 From the formulas appropriate for the weld joint (double sided fillet, double sided partial penetration groove, or single sided welds - fillet or partial penetration with limitations) and the throat size, calculate the weld stress. Conversely, from the desired stress level, solve for the required throat Design of Fillet Welds According to EN 1993-1-8 Dlubal where f u is the nominal ultimate tensile stress of the weaker part joined w is the appropriate correlation factor (see EN 1993-1-8, Table 4.1) M2 is the partial safety factor for resistance of welds. Example. Design of a fillet weld of the beam displayed in Figure 03 from .. Material:S235, f u = 36.0 kN/cm², w = 0.8 Internal forces:V z = 350 kN. Image 03 - Beam Determination of Weld Loads and Throat Requirements double-sided fillet weld is S. This T-joint is subject to bending in both the strong and weak directions, tension and shear. This bracket is made from ASTM A36 steel and welded with matching E60XX electrode. The required safety factor against ultimate failure is 3.0, so the allowable weld throat shear stress used to size the joint was 13

the product (effective area of the weld:T×W) of the theoretical throat (design throat thickness) and effective weld length as shown in Fig. 1. Fillet weld legs determine fillet weld sizes. Fillet weld sizes are measured by the length of the legs of the largest right triangle that may be inscribed within the fillet weld cross section. Fig. 1 Fillet Weld Size Calculation Equations for Welding Joint Oct 07, 2012 · The basic steps required, as per BS 5950, for fillet weld design calculations where the welded jointed structure is subjected to bending moment load are:Calculation of unit throat weld area (Au):If you have a fillet weld line of, say, 50 mm long (L), then the unit throat area of the welding joint can be calculated as: Fillet weld design - Steel Connection Design Calculations Eurocode 1993-1-8:2005 gives a designer a choice between two methods for the design of fillet welds:the simplified and the directional methods. There is no specific guidance on which method to use and, in practice, the choice is usually made on practical grounds.

The thickness of all fillet welds is taken as the throat thickness in strength calculations. For volume calculations, the cross-sectional area of the weld is defined by the triangles in Fig 1 identified as; ' contributes to strength '. The excess material is not considered in the welding calculator's calculations as this will vary with the welder but will usually represent a pro-rata increase Welding Job Knowledge:Fillet Weld DesignJan 14, 2019 · For a fillet weld loaded in shear (the load parallel to the weld) the calculation of stress on the weld is simple; it is the load divided by the area of the weld throat. It is assumed for design purposes that fillet welds fail through the throat and it is therefore a simple matter to calculate the cross-sectional area capable of carrying this Welding Job Knowledge:Fillet Weld DesignJan 14, 2019 · For a fillet weld loaded in shear (the load parallel to the weld) the calculation of stress on the weld is simple; it is the load divided by the area of the weld throat.
