Multi-engine cover, trunk lid. the doors and front fenders are bolt-on and easy to replace. During installation, the air gaps must be observed, otherwise, for example, the door will knock or increased wind noise will be observed when driving. The air gap must be at least parallel along its length, i.e. the distance between the body parts must be kept constant along the entire length of the gap.
For better protection against rust, the body is galvanized. At the same time, external parts of the body, such as the lid, side parts, fenders, roof and doors are electro-galvanized on both sides. Invisible details. as the bottom, door pillars, sheet stiffeners are thermally galvanized on both sides.
In electrolytic galvanizing, zinc is dissolved with the help of an electric current and applied to steel plates. A very uniform and thin zinc layer is formed, which can be processed further without problems. Due to the very smooth surface, these parts are suitable for external lacquering.
During thermal varnishing, the plates are immersed in a zinc bath at a temperature of +450°C. This forms an extremely thin layer of iron-zinc alloy, which serves as a connection for a layer of pure zinc with a thickness of 10 microns (1/100 mm).
If welding is required, use only spot welding. Only there. where the electric holder is not included, it is possible to use electric welding in a protective gas environment. The following points must be observed:
welding current (amps) increase by 10%, maximum by 30%.
Use hard-drawn copper electrodes with high heat resistance (above +400°C).
Frequently clean the electrodes by working them from the side up to a diameter of 4 mm.
Increase the pressing force of the electrodes.
Extend welding time. The welding time is correct if the weld points are spatter-free.
Caution: When welding galvanized parts, poisonous zinc oxide is released, so ensure that the workplace is well ventilated.
Then cover the welding points with cold galvanizing and prime.
