Abstract
Methods of forming a weld joint using rotating shielding devices are disclosed. To form the weld joint, the rotating shielding device may 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, disclosed methods of welding may improve efficiency of techniques such as vertical welding. During welding, rotating shielding devices may be coupled to a shielding gas supply, such that the shielding gas exits through an outlet formed in an axle of the rotating shielding device as the device is rotated and moved along the seam. 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.
