Red Seal Sheet Metal Worker Practice Exam

What is a common purpose of using a slip roll machine?

1. To cut sheets into strips

2. To create flat sheets from coils

3. To create cylindrical shapes from flat sheets

4. To weld metal pieces together

The correct answer is: To create cylindrical shapes from flat sheets

The purpose of using a slip roll machine is to create cylindrical or curved shapes from flat sheets of metal. This equipment is designed to bend and form metal sheets through a series of rollers that gradually shape the material into a desired curve or cylinder. The adjustable rollers facilitate the process, allowing for controlled and consistent bending, which is essential for achieving the specific radius or diameter needed in various applications, such as ducts and other cylindrical components in sheet metal fabrication. In contrast, other options outline processes that are not performed by a slip roll machine. Cutting sheets into strips, creating flat sheets from coils, and welding metal pieces together involve different tools and techniques, such as shears, rollers, and welding machines, making those options unsuitable for the primary function of a slip roll machine.
