Panel beating is the technique of repairing and reinstating a truck back to its original, new state, following a mishap or as part of the repair project. Truck panel beaters have vast knowledge and experience in respect to panel beating. Panel beaters specialise in various areas of expertise. For example, if you need repair work on your boat you may call in a boat panel beater. Some have specialty in repair of classic or vintage cars while others deal mainly with collision repairs. A number of techniques are often used by truck panel beaters when eliminating dents and restoring a damaged truck into a new truck. Here are some of the main techniques applied in panel beating.
Panel beaters are able to pound out metal dents by placing a dolly on the inside of the dented bodywork and hammering the other side using a pounding hammer. When the metal is pounded, part of it bulges in while the surrounding metal budges out. Panel beaters work around the dent, pounding the rebound section of the dents. With time, the rebound dent goes down, and the deep dent disappears.
When the body work of a car is smashed, the damaged area often gets stretched out due to the crash impact. Apart from the use of a shrinking hammer, panel beaters may also use an alternative shrinking technique. This approach seeks to heat the stretched area until it’s red hot and then applies water onto the area to quench the metal. As a result, the metal shrinks quickly and solidifies, and the metal section becomes strengthened.
This is a hand-driven technique that involves applying surface finish to the bodywork by finely contouring and smoothing it. A unique hammer known as a planishing panel hammer is used to straighten the damaged panel, re-establishing the original outline. The panel is pushed against a contouring tool, referred to as a planishing stake. Basically, the shape of the planishing stake matches up to the desired work piece shape of the panels and thus helps to re-establish the original outline.
Truck panel beaters carry out welding by melting metal pieces and incorporating a filler material to create a weld pool that cools to form a strong joint between two corresponding metal surfaces. Various energy sources are used to generate the weld, such as gas flames, lasers, electric arcs, electronic beams and ultrasound.
Lastly, the restored panel is spray painted using a strong paint, which is resistant to chipping. Before painting, the panel is sanded and primed to ensure the paint sticks well and to ensure the achievement of a smooth surface finish. The type of spray paint chosen should match up the original paint colour of your vehicle so that the panel repairs may remain undetected.
