A plate 100 mm wide and 12.5 mm thick is to be welded to another plate by means of parallel fillet welds. The plates are subjected to a load of 50 kN. Find the length of the weld so that the maximum stress does not exceed 56 MPa. Consider the joint first under static loading and then under fatigue loading.
Problem 3.1: Determine the design strength of a 1 mm length of a 6.35 mm fillet weld formed by the shielded metal arc process (SMAW) and E70 electrodes with a minimum tensile strength Fexx = 483 MPa.
