What is an ironworker's primary tool for cutting steel?

The primary tool for cutting steel used by ironworkers is the oxy-acetylene torch or plasma cutter. These tools are specifically designed for cutting through various types of metal, including steel, with precision and efficiency.

The oxy-acetylene torch utilizes a flame produced by mixing oxygen and acetylene gas to reach high temperatures capable of melting steel. This makes it ideal for cutting along intricate shapes or making straight cuts in heavier materials.

Similarly, a plasma cutter uses an electric arc and a gas to create a plasma jet that can cut through conductive metals. Both tools are favored in the industry for their ability to cut through thick materials quickly, allowing ironworkers to perform the necessary tasks on-site efficiently.

While other tools, such as band saws and angle grinders, can also cut steel, they are generally utilized for specific applications or smaller tasks. The hammer and chisel can shape or break metal but are not practical for cutting large pieces of steel. Thus, the oxy-acetylene torch or plasma cutter remains the primary and most effective choice for steel cutting in ironworking.
