Two 20-mm steel plates are butt-welded together. Both the plate and the welding = 500 MPa and electrode materials correspond to strength properties of Su S₁ = = 400 MPa. The imposed loading fluctuates rapidly between -20 and +60 kN. Estimate the length of weld required in order to provide a safety factor of 2.5: (a) If the weld reinforcement is not removed. (b) If the excess weld material is carefully ground off to provide smooth, continu- ous surfaces.
