Welding Yield Strength. Fillet welded lap subject to Torsion and shear Rectangular Block Subject To Torsion. 70 Indicates how strong this electrode is when welded.
If the yield strength of the steel is 60000 psi and the 1 square bar is in tension you multiply the 60000 by 06 to get the allowable load on the bar. We typically use E70 electrodes which have a yield strength of 70 ksi. WELDS-STATIC AND FATIGUE STRENGTH-II The yield stress of the weld metal is also raised due to the quenching effect.
The yield strength the stress that can be applied to a base metal or weld without permanent deformation of the metal.
3637972 of 14 fillet weld. 1 Indicates in what welding positions it can be used. 8 Indicates the coating penetration and current type used. Not only do you need to select a filler metal that matches the lower-strength material but you also may need to find a filler metal capable of being stress-relieved.
