Ex Welding.pdf → The Figure shows a 0.75-in-thick AISI 1020 HR steel bar subjected to a load of (F = 1.4 kip) and welded to a vertical support using a 7010 electrode. Estimate the shear stress for the weld. For the AISI 1020 HR steel bar, S, = 30 kpsi, Su= 55 kpsi (from the table) From the pattern of weld shown below, b= d = 2 in (welding table) bd2 * = b/2 ý = d/2 A = 1.414hd Then, A = 1.414hd = 1.414(5/16)(2) = 0.884 in?
