The arc welding technology area focuses on the most commonly used arc welding processes, mainly GMAW/MIG, GTAW/TIG, SMAW/stick, and plasma. The articles and press releases cover processes and power sources, plus all of the related items—electrodes and wire, wire feeders, fixtures, manipulators, positioners, and power sources. If you need information on personal protective gear, ventilation systems, and safety practices for welders, see our Safety coverage area.

Automatic orbital gas tungsten arc welding is used in a variety of industries in which maximum leak integrity, high performance, or ultra-cleanliness is important. Automatic orbital welding provides enhanced precision and reliability compared to manual techniques. Small, portable inverter power supplies, advanced control systems, and other advancements have made orbital welding systems practical for a range of applications.

Thanks to a specific vision and a high-end equipment purchase, C.F. Roark Welding & Engineering Co. Inc. is anything but ordinary. Founded in 1949, the company specializes in electron beam (EB) welding of complex, specialty parts and components for the aerospace, defense, and research industries. In a short amount of time it has carved a niche as the premier EB welding firm of the Midwest.
Autogenous orbital welding on large projects has become nearly routine with large numbers of successful welds completed with very low reject rates. Thus it is very easy to become complacent. However, installers need to be alert to potential problems and take immediate action when a problem occurs.
