Abstract
A system and method provide gasless, mechanized, field welding of an exterior of a tubular structure such as a pipeline, without the need for an enclosure. An embodiment consolidates some of the welding equipment on a skid for ease of transport to and from a remote worksite. The gasless weld may be achieved despite the presence of wind, by precisely controlling an arc voltage as disclosed. The footprint and weight of the system may be minimized, along with the associated labor, expense, and environmental impact otherwise incurred by conventional welding techniques using enclosures.
