Patent ID: 10265801

Abstract:
Rotating shielding devices for supplying a shielding gas to a weld pool as a weld joint is formed may be configured to be moved continuously along a seam formed between two structures being welded, so as to avoid having to remove the rotating shielding device during, for example, welding around corners. In this manner, rotating shielding devices and methods of welding may improve efficiency of welding techniques such as vertical welding. In operation, rotating shielding devices may be coupled to a supply of shielding gas, which may exit through an outlet formed in an axle of the rotating shielding device. The rotating shielding device may contain a plurality of partitions defining one or more chambers, the partitions and chambers being positioned between spaced-apart rotating portions, with the rotating shielding device configured to direct the shielding gas towards the weld pool during welding.
