In view of the problems of poor quality, low efficiency and waste of the traditional welding process of vertical steel bars, the company adopts the vertical steel bar electroslag pressure butt welding process in the construction, that is, the end of the steel bar is melted by the resistance heat generated by the current through the slag pool. Then apply pressure to make the welding process of the steel bar, and find out a set of welding joint quality inspection methods such as appearance inspection and mechanical property test, and put forward that in the operation, it should be noted that the end face of the welded steel bar should be flat, the end should be straight, and the flux should be used. It must be baked before, the steel bars must be clamped, and the key problems between the upper and lower steel bars should be tightly aligned. Through the use of vertical steel slag pressure butt welding process, the welding quality has been improved and good economic benefits have been achieved.
