Welding can be done with a variety of metals, but it's most commonly used with steel and aluminum. Steel is the most common choice because it's strong and easy to weld, but aluminum also has its benefits. Aluminum doesn't corrode, and it's lighter than steel, making it more efficient for some applications.

There are several factors to consider when choosing a welding service: the type of metal being welded, the thickness of the metal being welded, the size of the project, the skill level of the welding crew, and the price of the welding service.

When choosing a welding service, it's important to consider both the technical skills required and the crew's experience. It's also important to find a welding crew that has experience working with your particular metal type and with your specific project requirements. Finally, it's important to determine how much the welding crew will charge to do the work and how long it will take to complete the job. 

High-quality welders can create features at a variety of angles, such as 45-degree angle bends in tubing or pipe, as well as butt joints in flat stock. The type of welding required depends on the desired result. For instance, certain welding applications require heavy-current applications, while others may require more DC current output with cooled spool guns. Welder welds aluminum, steel and other materials that are a good fit for the application.
