θ – angle of loading measured from the weld longitudinal axis, degrees Base metal strength is evaluated if the option is selected in Code setup (Base metal capacity at the fusion face). The residual stresses of welding can be reduced through thermal stress relief, although for most structural appli-cations, this is economically impractical. Adding twice the leg length for stops and starts gives 85 mm: use 90 mm. 3, differ in two ways from the full penetration welds: the reduction in cross section and the uncertainty of the weld root quality. Accordance with mild steel, for high strength steels, the deformation capacity of longitudinal fillet welded joints (1–4 mm) is larger than transverse fillet welded joints (<1 mm). Provide an intermittent 6mm fillet weld on both sides of the web, 90 mm hit and 110 mm miss. Transverse fillet welds in lap joints transferring stress between axially loaded parts shall be double-fillet welded (see Figure 2.5) ex-cept where deflection of the joint is sufficiently re-strained to prevent it from opening under load. For more accurate calculations, we therefore recommend controlling the load-bearing capacity of welds only for that part (length) of the weld that has a rated section. A throat area of the weld group [mm 2 , in 2 ] Plz concentrate on the words When the applied force is parallel to the length of the weld is called longitudinal fillet weld. The 6mm leg fillet weld length required (longitudinal resistance, 1.01 kN/ mm) over 200 mm = (200 × 0.37)/1.01 = 73 mm. If the joint is loaded in plane, (Ts = 0 ) and there is a transverse component For two welds, this is 0.37 kN/mm per weld. Notation. For a lap joint, Tj also represents the transverse shear. longitudinal fillet or slot welds. For complex structural applications, temporary shoring and other con-ditions must be considered, as the steel will have a great-ly reduced strength capacity at stress relieving temperatures. 2.4.8.1 Double-Fillet Welds.

Firstly, Strength of Fillet Welds as a Function of Direction of Load Transverse welds show about a 44% strength increase over longitudinal welds but show a decrease in deformation capacity in that longitudinal welds are nearly four times more ductile than transverse welds BY L. J. BUTLER AND G. L. KULAK Introduction The strength of a fillet weld is de­ For example, for a weld group containing longitudinal and transverse welds, the longitudinal weld can only develop 85% of its full capacity before joint failure, which is reflected in Equation J2-­10b. Longitudinal direction Transverse direction (a) Fig.2 (a) Load applied in transverse direction (b) longitudinal shrinkage restraint (b) Partial penetration welds, shown in Fig. Check this switch in order to consider only the effective weld length during the strength checks of the connection. R n = F nBM A BM – AISC 360-16 – J2.4 (J2-2) Common solution for combined loading Loading in the plane perpendicular to the weld plane induces a tensile or pressure stress σ in the weld. represents the weld joint longitudinal shear, and Tj represents the tension or compression in the terminated part through the weld joint. e = eccentricity F EXX = Filler metal classification strength
