Resently many high rise buldings are constructed and materials of those buldings have high strength. We use enclosed arc welding to joints of high strength steel bars. When tensile are aplied those joints, fracture occurs at the bonds of welded joints frequently. This report proposes suitable chemical composition of steel bars and welding technique to prevent fracture of bonds. Results are as follows. "Ceq=C+Mn/6+Si/24≦0.47%" With improvement of welding technique showed in this report. Results are as follows. "Ceq=C+Mn/6+Si/24≦0.51%" Within above mentioned requirements, fracture of bonds of welded joint is prevented. When welded joints of steel bars in bulding construction are used, it is necessary to take Ceq of mill steels into consideration.
