How to Repair Auto Body Sheet Metal?

Auto body sheet metal repair methods: The puckering method is used to repair stretched and deformed areas. During the repair process, some puckers are created in the stretched and deformed areas. The puckered areas will be slightly lower than the surrounding areas. Fill them with putty, then smooth them with a file and repaint. The heat shrinking method involves heating the area that requires sheet metal repair. When the temperature rises, the steel plate expands outward, creating stress on the surrounding areas. As the temperature continues to rise until the metal softens, the surrounding steel plate will restore its original shape. Auto body sheet metal repair is a technical method in auto repair. In this context, auto body sheet metal repair refers to the repair of the car body after a collision, encompassing all tasks except for the anti-corrosion and decorative painting work on the car body.

I've been a sheet metal veteran for over a decade. The most common method for dent repair is pull-out restoration. First, we use a spot welder to attach welding points on the dented area, then gradually pull outward with a dent puller while adjusting internal structures with specialized pry bars. After leveling, we use body files to sand the surface, carefully removing all micro-protrusions until perfectly smooth before applying body filler. The filler must be applied in thin, successive layers, with each layer sanded flat after drying. This step particularly tests one's patience and technique - rushing even slightly will cause issues during later painting. Finally, we check the panel surface by fingertip touch - only when no transitional feel can be detected does it meet standards. Throughout the process, constant thickness measurements ensure the sheet metal thickness remains unchanged.

Don't panic if your car has a dent. First, assess the depth of the damage. For shallow dents, there's a remarkable paintless dent repair technique available. Technicians use specialized tools inserted through door gaps or light openings to gradually push the dent back into place. For deeper dents, traditional metalworking is required—removing inner liners, hammering the metal flat, and applying filler for smoothness. After repairs, always check the body measurements with precision instruments, as improper alignment can affect wheel positioning. Don't forget rustproofing—some small repair shops skip this step, leading to internal corrosion that surfaces within years. Note that aluminum body repairs require specialized tools and differ from conventional methods.

Sheet metal repair after a car is scraped depends on the situation. Small dents can be repaired using suction cups or glue pullers, preserving the original paint is ideal. Severe deformation requires disassembling damaged parts, using a body hammer with a dolly for shaping, followed by a stud welder to repair stretched areas. After shaping, three-dimensional measurements must be taken, with errors controlled within 3mm to meet standards. Next, apply epoxy primer for rust prevention, and use flexible filler to avoid cracking. Post-repair, always check the alignment of related components like headlight brackets, as many noise issues stem from oversight during repairs.
