Abstract
A resistance point welding apparatus for fixing a turbulence installation body to an inner wall of a steam generator pipe, having a welding head, which is introduced into the pipe and includes a lance having an electrically conductive material, a point welding electrode, which projects out of the lance in the radial direction, an effective element and an insulation body, which is opposite the point welding electrode in the radial direction and is moved by the effective element, is provided. The lance is tapered at a defined distance from the welding head end such that the insulation body and the point welding electrode press the turbulence installation body against the inner wall of the pipe when the effective element is activated. When a welding stream is impressed on the lance, a point-like welding stream flows via the point welding electrode to a counter electrode arranged outside the pipe.
