◦ Important to observe that the electrode material is often the

strongest material. According to AWS standard

AWS electrode Tensile Strength Yield Strength % Elongation

E70XX 70 (482) 57 (393) 22

E80XX 80 (551) 67 (462) 19

◦ When the component are made of material such as high carbon
steel or alloy steel, The weld deposit weaker than the strength of the

connected component. The properties of weld deposit such as

tensile strength and yield strength are considered as a criteria for
determine permissible stresses (η = 3-4)(Jennings)
