What is the purpose of using a hammer and dolly in metal repair?

Using a hammer and dolly in metal repair primarily serves the purpose of shaping and smoothing the metal surface. When a vehicle's body experiences dents or deformities, the hammer is used to strike the metal while the dolly provides support from behind. This combination enables the technician to effectively reshape the metal back to its original contour.

The hammer techniques allow precision in manipulating the metal’s surface while minimizing damage, ensuring the repair maintains the integrity of the original design. Achieving a smooth finish is also crucial, as it prepares the surface for subsequent processes such as painting, ensuring a high-quality aesthetic result. This process is fundamental in auto body repair, making the hammer and dolly vital tools for restoring vehicle appearance and functionality.
