To manage problems related to yield stress, engineers and scientists rely on a variety of formulas dealing with the mechanical behavior of materials Ultimate stress, whether it is tension, compression, shearing or bending, is the highest amount of stress a material can withstandThe stress corresponding to the yield point is called yield point stress The point B is the upper yield stress point and C is the lower yield stress point 4 Ultimate Stress Point It is the point corresponding to the maximum stress that a material can handle before failure It is the maximum strength point of the material that can handle theDepending on the electrode, you can undermatch, overmatch, or match the weld strength to the base material We typically use E70 electrodes which have a yield strength of 70 ksi For wide flanges we typically use 50 ksi steel So when you weld a wide flange given the parameters above, you are overmatching (70 ksi weld vs 50 ksi steel) Engineering Fundamentals Refresh Strength Vs
