Method for carrying out stud welding on flat workpiece

The invention discloses a method for conducting stud welding on a flat plate workpiece. The method comprises the following steps that the fixing position of a stud to be installed on the flat plate workpiece is preset; according to the preset fixing position, a plurality of round nests for installing the studs are machined in the flat plate workpiece; the round nest is of a cylindrical structure, and the diameter of the round nest is larger than that of an arc striking protrusion of a stud to be installed. The round nest is coaxial with a preset fixed position; and the stud to be installed and the round nest are coaxially arranged, and the stud to be installed is welded to the round nest. According to the method, the round nest of the cylindrical structure is machined in the preset position of the stud in a numerical control mode, meanwhile, the round nest and the preset stud are coaxial in the fixed position on the flat workpiece, the to-be-installed stud and the round nest are coaxially arranged, accurate p
