How to repair alloy wheels

It frequently happens that the potholes on the roads are detrimental to our cars. Sometimes the bumps, cracks and potholes and asphalt guilty in an accident, but most often it is that damage is molded discs. It's a shame that buy the CD with the desired pattern is very difficult. Easier to buy a new set of disks. Unfortunately, this is a very expensive method of getting rid of the problem. Of course, you can seek help from the car wash, but it is not cheap. Undertake repair work can be their own. If the injury is not serious - however, small cracks or scratches, to cope with it not so difficult. Since this is a purely visual defect, to cope with it, you can use sweep, straightening and painting. Much harder to repair in the lateral runout or loss of any part of the disc. Axial runout to straighten with balance, because this failure is very insidious. It necessarily affects while driving down the road, especially at speeds close to 100 km / h. In case of loss of the disc will have to welding. Before you begin, you should clearly define the procedure. For example, if a portion of the disk is missing, you should pick up the material from which could be part of this cut. After a careful selection of material make all the necessary measurements. The next step will be cleaning and degreasing of those parts of the metal to be exposed to welding. As a rule, these works used argon-arc welding. In carrying out welding work should be followed as carefully as possible. This requirement applies not only safety but also the aesthetic side of repair. What would be neater seam, the easier it is to make invisible. Once all the elements are welded cast disc, proceed to the treatment of joints. Protruding above the surface of the weld to whittle down a large abrasive sandpaper, followed by grinding to produce seamless abrasive sandpaper with a smaller one. Now, when the level of weld on par with the level surface, place rihtuem repair and paint carefully chosen paint. Sure, the paint color should be chosen as closely as possible to avoid the difference of colors on a single disc. In principle, we can paint the entire disc, or even all four discs. After these procedures should drive carefully dry. If all the repairs were carried out rather neatly repaired disk can be very difficult to distinguish from new.
