1.       Two 8-mm-thick by 50-mm-wide A572 Grade 42 steel straps are welded together with fillet welds in a lap joint using E70 electrode. The tensile load of 45 kN on the straps is orthogonal (transverse) to the welds. What is your recommended weld size for the two full-length welds?

2.       Two 8-mm-thick by 50-mm-wide A572 Grade 42 steel straps are welded together with fillet welds in a lap joint using E70 electrode. Determine the fillet weld size needed for a dynamic load that varies from 0 to +12 kN using a safety factor of 1.5 for infinite life of the two full-length welds.
