Proper fastening of resistance-welded components requires equipment where both welding energy and welding time can be controlled. Accurate equipment for this purpose is necessary in order to achieve the desired quality in the repair.

The technique of using welded attachment components has extremely good anti-corrosion properties. The welding unit should also be able to handle the welding of attachment components such as T rivets and screw rivets as well as studs or washers that can be used during body alignment.

The placement of attachment components on the car requires easy-to-handle equipment with a flexible welding gun.

It should be possible to convert the welding unit from normal resistance welding and welding of studs/washers used during body alignment.

In general, trial and error is required to develop a good welding result prior to actually welding on the car. Test pieces of the metal are welded with different current strength and welding time until the result is satisfactory. For spot welding, the electrodes should have a diameter of max 6 mm. The spot weld core should have a diameter of 5 mm to ensure strength.
