The present invention relates to a method of manufacturing a T-bar configured to manufacture a welded T-bar through the submerged arc-butt welding of a steel plate to a T-shaped steel, which is a surplus steel, after manufacturing a T-bar by plasma-cutting a web of an H-shaped steel. A method of manufacturing a T-bar according to an embodiment of the present invention includes: (A) a step of preparing an H-shaped steel; (B) a step of plasma-cutting any one of the webs of the H-shaped steel to manufacture the T-bar; and (C) a step of manufacturing the welded T-bar by welding the web portion and the steel plate of a T-shape steel which is the surplus steel of the H-shaped steel in a state where the web portion and the steel plate are put in the same straight line. As such, the present invention can provide a uniform corner portion.
