Welding rigs are mobile workstations equipped with welding equipment, power sources, and tools necessary for on-site welding projects. These rigs are designed to provide a stable platform for welding in remote or difficult-to-reach locations, such as oil rigs, pipelines, or construction sites. They come in various sizes and configurations to suit different welding applications, from small-scale repairs to large-scale construction projects. Welding rigs are operated by trained and certified welders who use them to join metal parts using various welding techniques, including MIG, TIG, and stick welding.
