Abstract
The arc welded joints of high strength deformed bars have been studied. Butt, lap, and splice joints were used. The ultimate strength of high strength deformed bars varied from 60, 000 psi to 80, 000psi. Ordinary manual arc welding and enclosed are welding were used. The results are obtained as follows : (a) the bend test about the short beaded is the most convenient method to determine the weldability of the bars; (b) suitable preheating is needed to obtain good welded joints.
