Example 1


       Weld joints subjected to static axial and direct shear loading. Estimate the

         static strength of a parallel loaded fillet weld. The plates in figure below

         are 12 mm thick and made of steel having yield strength, S 350 MPa.
                                                                                                               Y
         They are welded together by convex fillet welds along sides AB and CD,

         each of which is 50 mm long. With a safety factor of 3, what static load, F

         can be carried using a 6 mm weld leg?





      Analysis are as followed:                                                                                     A         B


      Total weld throat area is

                                                                                                                          l =50 mm








      Distortion energy theory is









      Thus, the eccentric static load is                                                                                            129
