Fy = yield strength of base metal (ksi) E70XX weld electrode is assumed above (70 ksi yield) Case 1 For fillet weld on one side of material thickness t(min) = 1031*w (for Fy = 36 ksi material) t(min) = 0742*w (for Fy = 50 ksi material) Case 2 For fillet weld on both sides of material thickness t(min) = 62*w (for Fy = 36 ksi material)If the material yield strength equals 30,000 pounds per square feet and the wall thickness is 3 inches 30,000 x 3 = 90,000 Multiply your answer by 2 Using the example in Step 1 90,000 x 2 = 180,000 Multiply the pipe's outside diameter by the pipe's safety factorT = K F d (1 l/100) (1) where T = wrench torque (Nm, lbf ft) K = constant that depends on the bolt material and size d = nominal bolt diameter (m, ft) F = axial bolt force (N, lbf) l = lubrication factor (%) Typical values for K with mildsteel bolts in range 1/4" to 1" normal dry K = 02 Helical Spring Design Guide Xls Yield strength calculation excel
