Abstract
A level entry bore welder that is easier to use and less expensive to purchase. It has an adjustable step feature that allows the operator to control the bead placement inside the bore of a work piece. It includes a simple remote control apparatus that adjusts the welding torch rotation speed as a function of the diameter of the bore. The remote control apparatus also permits the operator to turn the wire feed mechanism on and off. The welder is suited for bores up to 12 inches in diameter.
Claims18
A portable bore welding machine for circular deposition of a weld bead on an inside surface of a bore, said machine comprising a torch assembly comprising a torch head attached to a torch head extension tube bottom end by a first adjustable swivel means, a second adjustable swivel means attached to said torch head extension tube top end for placing said torch head in a desired location adjacent to said inside surface of the bore, a motor assembly for advancing said torch head into the bore and for rotating the torch head around said inside surface of the bore, an electrical swivel connector for providing electrical connectivity to the torch head as it rotates, a feed assembly for feeding a consumable welding wire electrode to the torch head and a control assembly for controlling the operation of said welding machine.
A portable bore welding machine for circular deposition of a weld bead on an inside surface of a bore, said machine comprising a torch assembly comprising a torch head attached to a torch head extension tube bottom end and fixed at an angle thereto, an adjustable swivel means attached to said torch head extension tube top end for placement of said torch head in a desired location adjacent to said inside surface of said bore, an electric motor assembly for advancing said torch head linearly into the bore and for rotating the torch head around said inside surface of the bore, an electrical connector for providing electrical connectivity to the torch head as it rotates, a feed assembly for feeding a consumable welding wire to the torch head and a remote control assembly for controlling the operation of said welding machine.
