Presentation of the Stud welder or tire clous

Definition :

A stud welder, or drawing nails is a tool primarily used in body shops for straightening dents and deformations of the sheet metal panels. It works by welding of nails or pins special on the damaged surface of the sheet. Once welded, these nails are used as points of anchorage to apply traction, and straighten sheet metal.

Operation :

Surface preparation : The damaged area of the plate is cleaned to ensure a good grip of the nails.

Welding Nails : The stud welder soda rapidly nails at specific points of the sheet. The welding is carried out by a short passage of electric current through the nail, generating heat sufficient to fuse the metal of the nail with the plate.

Application of Traction :

A tool of power (usually a hammer to inertia or a lifting device) is attached to the studs welded. By pulling on this tool, the technician performs a controlled force to straighten the sheet.

Removing the Nails :

Once the plate adjusted, the nails are removed, and the surface can be sanded and finished to remove any imperfections remaining.
This process allows you to repair the body panels without having to disassemble the parts, thus providing a solution that is fast, accurate and cost-effective for the repair of damaged vehicles.
