Red Seal Sheet Metal Worker Practice Exam

What is often added to sheet metal to prevent sharp edges?

1. Beveling

2. Welding

3. Seaming

4. Finishing

The correct answer is: Beveling

Beveling is a process where the edge of the sheet metal is tapered, creating a sloped angle rather than a sharp corner. This technique helps to reduce the risk of injury from sharp edges, making it safer to handle and work with the metal. In many applications, particularly in areas where individuals will be in contact with the metal, such as in HVAC installations or in the manufacturing of appliances, beveling serves as an effective way to enhance safety by minimizing the possibility of cuts or scratches. In contrast, welding, seaming, and finishing may serve different functions. Welding connects pieces of metal, seaming involves joining edges for structural integrity, and finishing enhances the surface for aesthetic or protective purposes. While these techniques may also provide some level of edge treatment, they do not specifically target the reduction of sharpness in the manner that beveling does. Thus, beveling is uniquely recognized for its role in preventing sharp edges.
