Cutaway car generally refers to a type of smuggled car. It cuts complete cars into parts, usually a sedan in three large pieces, in order to use a small ? Fidelity? (motorboats with more than four engines) to be loaded or placed in containers for smuggling. It is rewelded and repainted in the smuggling syndicate's factory to look like a new car to be resold. Because the car was cut and rewelded, the original overall safety features were destroyed. The wing and C-pillar are one piece and the cutting starts at the C-pillar. The original welds have to be drilled out before the cut can be severed.
After drilling out the weld joints, they need to be rewelded, but the original weld joints are concave while the new ones are gas welded and raised, so the weld joints will disappear. If you don't sand it, the weld joint will be raised. You can see there is still a weld at the top of the picture, but it disappears at the bottom. It's a typical cut with raised weld joints that are poorly polished. In the welding shop of an automobile factory, I can briefly describe the process from welding to painting: 1. The company that supplies the parts will send them to the shop. Various parts would be sent to various production lines.
The production lines are responsible for producing the parts and components stamped out of the press shop into the various parts of the automobile. The automobile production lines are divided into packaging lines and main welding lines. The lines are divided into the front compartment, front floor, rear floor, left side wall, right side wall, longitudinal beam, and door caps. The main welding assembly line is responsible for putting together the parts produced by the teams into a body. After the main welding wire has welded the body, it will reach the adjusting wire. The adjusting line is responsible for installing the four doors, hair covers, and various nuts. After passing through the adjusting wire, the grinding line will use mills and grinders to grind dings, defects, CO2 weld holes, etc. on the body.
When all the processes are complete, the BIW is sent to the paint shop via a plate chain. The paint tester is used to test the paint thickness. Normally the paint thickness is thicker where the cuts are made and putty is applied. However, the newly welded fenders have a thinner paint thickness because they are original and a little paint will do the trick. Finally, to summarize, if there is paint on the inside of the C-pillar, be sure to pull out the seals, check the weld joints, and use a paint tester to further test to determine whether there is a cut or sheet metal repair, because the C-pillar repair and welding are accident cars. Check the welded joints mainly to see whether the welded joints are uniform, whether the same steel ends are welded, whether the cross-section is uniform, and whether it is lubricated to the touch; if A/B/C columns are injured in a car accident, the corresponding position needs to be cut, and the cut part will not be the original welded joints, the strength is not as good as before, and the consequences of the second accident are unimaginable.
