Technology of Automatic Orbital Welding of Small Diameter Pipelines of Carbon and Low-alloy Steels

Welding of small diameter pipelines of carbon and low-alloy steels is in great demand in various industries. However, the scientific literature covering all welding methods of said pipelines practically does not exist. The article analyzes the existing literature, as well as the own developments of the authors. The review found that technologies of non-consumable electrode welding in inert gases are the most common. The ar t icle present s the main point s of a non-consumable electrode welding in inert gases and the ways of future development of small diameter pipe welding of carbon and low-alloy steels.
