Abstract
Abstract A welding device including a welding head and circular welding mechanism detachably secured thereto. The circular welding mechanism includes a barrel and a housing. The barrel is detachably secured to the housing and rotatably driven by a drive therein so as to make circular inside or outside welds on a workpiece. The barrel comprises a first connection end adapted to be secured to the housing and a second remote end telescopically and angularly adjustable with respect to the connection end.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
117 words
A welding device for welding circular welds with a length of welding wire comprising a welding head with an associated drive therein for feeding said welding wire, a circular mechanism detachably connected to said welding head, means for supplying inert gas to the circular welding mechanism, said circular welding mechanism including housing means containing motor drive, angle drive gearing, and an adapter driven by said drive gearing, said circular welding mechanism also including a hollow barrel having a connection end connected to the adapter for rotation therewith, and a remote end, the remote end being disposed at an angle with respect to said connection end for effecting a circular weld as the adapter and barrel are rotated.
Claim 2
Dependent Claim
117 words
A welding device for welding circular welds with a length of welding wire comprising a welding head with an associated drive therein for feeding said welding wire, a circular mechanism detachably connected to said welding head, means for supplying inert gas to the circular welding mechanism, said circular welding mechanism including housing means containing motor drive, angle drive gearing, and an adapter driven by said drive gearing, said circular welding mechanism also including a hollow barrel having a connection end connected to the adapter for rotation therewith, and a remote end, the remote end being disposed at an angle with respect to said connection end for effecting a circular weld as the adapter and barrel are rotated.
Claim 3
Dependent Claim
34 words
A welding device as in claim 1 wherein the remote end is telescopically secured to said connection end so as to selectively position the tip of the remote end at a selected adjusted position.
Claim 4
Dependent Claim
23 words
A welding device as in claim 1 wherein the remote end is both telescopically and angularly adjustable with respect to the connection end.
Claim 5
Dependent Claim
44 words
A welding device as in claim 1 wherein the remote end is telescopically adjustable with respect to the welding head to accommodate different size workpieces and is angularly and rotatably adjustably with respect to the connection end for making either inside or outside welds.
Claim 6
Dependent Claim
20 words
A welding device as in claim 1 including fastening means detachably joining the adapter and connection end of the barrel.
Claim 7
Dependent Claim
91 words
A welding device as in claim 5, wherein the adapter has an opening therethrough and the housing means includes an inlet block having a longitudinal opening for receiving welding wire from the welding head, a hollow shaft rotated by the angle gearing having an opening therethrough, said shaft opening communicating at one end with the inlet block opening and at the other end with the adapter opening, whereby welding wire may be fed through the openings in the inlet block, hollow shaft and adapter into the barrel, which openings are aligned.
Claim 8
Dependent Claim
55 words
A welding device as in claim 6 wherein said inert-gas-supplying means includes a connection on said housing means communicating with said aligned openings in the hollow shaft and adapter to the hollow barrel for discharge from the said remote end to provide a desired shielded atmosphere about the welding wire at the place of welding.
Claim 9
Dependent Claim
70 words
A welding device as in claim 6 wherein power means are connected tO the housing means for receiving power from a source, and communicating same to the adapter, the adapter and the barrel both being electrically conductive, whereby welding wire passing from the remote end of the barrel engages the remote end and carries current therefrom, thus striking an arc when the welding wire engages the work to be welded.
