What is a common use for air chisels in metalwork?

Air chisels are primarily used in metalwork for the purpose of tearing thinner metal after welding. This is due to their ability to deliver powerful, rapid blows that can quickly remove material or separate welded joints. The design of air chisels often allows them to work effectively on sheet metal and other materials where precision tearing or stripping is required.

In contrast, creating precise cuts in thick metal typically requires tools that offer greater control and cutting capabilities than what an air chisel provides. Polishing welds is usually done with specific tools designed for finishing surfaces rather than using an air chisel, which is more suited for cutting and tearing operations. Additionally, air chisels do not apply heat during cuts; instead, they rely on mechanical force to break the material apart. Therefore, the use of air chisels aligns with their intended function, making them ideal for tearing thinner metal after welding.
