Abstract
Abstract A welding head assembly has a pair of rigidly connected, bifurcated, open-ended tubes with rollers which bear against one side of a plate projecting from the base plate to which it is to be welded. A weld wire emerges between the ends of the bifurcated tubes which carry a supply of flux to surround the tip of the weld wire. The assembly also has a downwardly depending arm which has a drive wheel. The arm is pivotably biassed so that the drive wheel bears against the other side of the plate with the result that the drive wheel propels the welding head assembly.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
140 words
A welding head assembly for automatically welding a projecting plate to another plate consisting of a hollow member moveable in a predetermined horizontal plane, a weld wire projecting from said hollow member, said hollow member supplying flux therethrough and around the projecting tip of said weld wire, a further member pivotably secured to said hollow member, rotatable means on one of said members bearing against one side of said projecting plate, driven rotatable means on the other of said members, and means coupling said members together whereby the driven rotatable means on the other of said members bears against the other side of said projecting plate to propel said welding head assembly along said projecting plate, the tip of said weld wire being adjacent to the juncture of said projecting plate and said other plate to provide a welded joint.
Claim 2
Dependent Claim
140 words
A welding head assembly for automatically welding a projecting plate to another plate consisting of a hollow member moveable in a predetermined horizontal plane, a weld wire projecting from said hollow member, said hollow member supplying flux therethrough and around the projecting tip of said weld wire, a further member pivotably secured to said hollow member, rotatable means on one of said members bearing against one side of said projecting plate, driven rotatable means on the other of said members, and means coupling said members together whereby the driven rotatable means on the other of said members bears against the other side of said projecting plate to propel said welding head assembly along said projecting plate, the tip of said weld wire being adjacent to the juncture of said projecting plate and said other plate to provide a welded joint.
Claim 3
Dependent Claim
41 words
A welding head assembly according to claim 1, wherein said hollow member is formed from the connection of the corresponding ends of a pair of spaced-apart tubular members, each providing a supply of flux to the tip of said weld wire.
Claim 4
Dependent Claim
48 words
A welding head assembly according to claim 1, wherein said rotatable means and said driven rotatable means comprise a pair of spaced-apart wheels bearing agaInst said one side of said projecting plate, and at least a single, opposed wheel bearing against said other of said projecting plate, respectively.
Claim 5
Dependent Claim
27 words
A welding head assembly according to claim 3, wherein said pair of wheels and said opposed wheel are positioned on opposed sides of said weld wire tip.
Claim 6
Dependent Claim
86 words
A welding head assembly according to claim 2, wherein said weld wire is carried in a rigid tube located between said tubular members, said rigid tube having an external pivot wheel bearing against a plate connecting said tubular members adjacent their respective open ends, and means moving said rigid tube at a point removed from the tip of said weld wire with respect to said pivot wheel to pivot said tube about said pivot wheel and alter the position of the tip of said weld wire.
Claim 7
Dependent Claim
17 words
A welding head assembly according to claim 1, wherein said driven rotatable means is a serrated wheel.
Claim 8
Dependent Claim
33 words
A welding head assembly according to claim 1, wherein said driven rotatable means is supported on said second member with drive means carried on said second member to drive said driven rotatable means.
