<p>PURPOSE: An automatic stud welding system equipped with a centering function by an automatic aligning unit is provided to simplify a process since a regular positioning jig device for a separate hand gun is not needed to be made, thereby reducing production costs and post-processing costs. CONSTITUTION: An automatic stud welding system equipped with a centering function comprises an automatic aligning unit and a stud welding unit. The automatic aligning unit (10) includes a frame unit, a base plate (200), a rear cross section fixing support roller (112A), a front cross section press roller, a left-right cross section support roller, a left-right cross section press roller (110A,B), rectilinear shuttling motion unit, and a drive unit. The stud welding unit welds and fixes at least one stud on a welding object which is centered by the rear cross section fixing support roller, the left-right cross section support roller, the front cross section press roller, and the left-right cross section press roller.
