Two plates, 25 mm thick, are welded together by means of trans verse-fillet welds. The
ultimate tensile strength of a weld metal is 415 MPa. The surface finish factor of the weld
surface is 0.5, and the size factor is 0.85. The reliability is 90%. Determine the length of
the weld if the factor of safety is 2. The transverse force on the welds is 100 kN, which is
completely reversed under fatigue loading. Take: A=10mm
