CHAPTER 6. WELDED CONNECTIONS 6.1

The shear failure of the fillet weld occurs along a plane through the throat of the weld, as shown in the Figure below. a a Throat = a x cos45o = 0.707 a a a Throat = a x cos45o = 0.707a Failure Plane L Shear stress in fillet weld of length L subjected to load P = fv = 0.707 a Lw P If the ultimate shear strength of the weld = fw Rn = fw ×0.707 ×a ×Lw Calculating Weld Volume and Weight - TWIWith a fillet weld or a 45° single bevel joint this is relatively simple but the calculations become lengthier as the weld preparation becomes more complex. Fig.1 illustrates how simple this calculation is for an equal leg length fillet weld; the area of such a weld is half the square of the leg length, Z.

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 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.

Consider Penetration When Determining Fillet Weld Size

When Determining Fillet Weld Size Practical Ideas for the Design Professional by Duane K. Miller, Sc.D., P.E. Design File Introduction A flat-faced, equal-legged fillet weld in a 90° T-joint has a theoretical throat dimension of 0.707 , where is the leg DETERMINATION OF WELD LOADS AND THROAT 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 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

Effective Area & Size

Nov 04, 2014 · Effective Area of Fillet Welds Click on image for larger view. It is important to note that fillet welds are specified by their leg size, a, instead of by the effective throat, t e. The vast majority of fillet welds are designed to have equal leg size, which makes t e = a*sin(45 o) = 0.707a. Fillet Weld Size Calculation Equations for Welding Joint Oct 07, 2012 · 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:Au =L*1=50 * 1=50 sq. mm.eq.1 Fillet Weld Throat Area Equations and Calculation Fillet Weld Throat Area Equations and Calculation, full length weld and Active Load bearing area.

How to Determine the Strength of a Transverse Fillet Weld

The theoretical throat is calculated by multiplying times the cosine of 45 which is 0.707. For all fillet welds with both legs being of the same size, the theoretical throat will be 0.707 x . If the weld is 20 inches in length then the effective area will be 20 x 0.707 x . Lecture 11.2.2:Welded Connections - UL FGGThe assumptions adopted for fillet weld calculations according to Eurocode 3 [1] concern mechanical and geometric characteristics. As already pointed out, the mechanical properties of the filler metal shall be compatible with the parent material properties. The throat area of a fillet weld considered in the calculation is shown in Figure 6. Weld Strength Calculator fillet vs butt CalQlataThe 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 Design

Jan 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 Welds in Shear, Bending, Torsion and Axial Loading User Feb 14, 2010 · The shape of fillet welds is usually triangular. As shown in the sketch, the outer surface of a weld is reinforced, i.e. made convex, but in strength calculations this reinforcement is ignored. The failure of welds usually occurs in the throat section. This area is therefore used in strength calculations of welded joints.
