Welding questions, answered by experts

Cutting round ductwork requires precision and the right tools. A duct cutter, specifically designed for circular ducts, is ideal. First, mark the cutting line on the duct using a measuring tape and pencil. Then, position the duct cutter's blade on the marked line. Apply steady pressure, rotating the cutter around the duct. The sharp blade creates a clean, precise cut. Alternatively, a reciprocating saw with a metal-cutting blade can be used for larger round ducts. Ensure the duct is securely held in place while making the cut to prevent slips and maintain accuracy.

While a high-speed circular saw will cut through metal, and even cut through multiple sheets at once, the fast-spinning saw blades create a lot of heat. This heat can damage paint and other protective coatings, leading to serious problems like rust over time. The cost to paint a metal roof again to avoid this damage is typically an additional $0.50 to $1 per square foot.

There are a few things you can ask welders before you hire them to get an idea of their experience and ability levels:

  • Are you licensed and certified?

  • How long have you been in the welding business?

  • Do you commonly do the type of welding I need?

  • Do you offer any kind of warranty for your work?

  • Do you charge by the hour or by the project?

  • How long do you expect my welding project to take?

  • What steps do you take to minimize errors in your work?

Welding is the process of using extreme heat—and, sometimes, pressure—to attach two pieces of metal. In contrast, metal fabrication is a more involved process that can include welding, sheet metal work, bending, and other forms of metal manipulation. Metal fabrication is a large-scale project that may or may not involve welding, while welding is more often a step in larger fabrication projects.

Yes, but you’ll need reliable steel-cutting tools and safety gear to get started. Shipping containers are typically around ¾ inch thick, so it’s entirely possible to cut through them, but experience and the right equipment are very important. When possible, try to get a container as close to the size you want it as possible.
