Measure “Leg lengths” is easy checking on site. 4) Heavy porosity on the surface of some MMA welds made on a construction site is most likely to be caused by : Use of the wrong class of electrodes. Use of excessive current. Moisture pick-up in the electrode … Nettet10. apr. 2024 · as calculated earlier, the allowable shear stress is 70,000 x 0.30 = 21,000 psi. To get A (effective area of the weld), first, we need to convert the leg length to the throat size. as we know a= z x 0.707 so we need to multiply the leg length as (1/2 x 0.707 = 0.3535 inches) times the length (10 inches) times 2 welds.
