The Koike Aronson / Ransome Automatic Girth Welder (AGW) A.K.A. (3:00, 3 O'clock Welder, ) performs x-ray quality horizontal welds up to 20 times faster than standard manual techniques, cutting in-field welding time for storage tanks by up to 40%.
Operating at speeds from four to 105 inches per minute, the AGW can handle plates as thick as 1 ¾" and tank diameters from the largest to as small as 15'. The adjustable A-frame telescopes manually to handle six- to 10-feet high steel plates.
Ergonomically designed for efficiency, convenience, and accessibility, the AGW includes the Lincoln NA-3 solid state control and welding head fitted with nozzles, wire feed rolls, strengtheners and 50 lb. wire reels for either single or twin-arc wire.
Lincoln NA-5 controls as well as a DC-1000 power source is also available. The submerged arc flux belt mechanism ensures retention of the flux at the joint for efficient recycling.
It is available as a single sided or dual sided mobile welding station completely equipped with welding heads, all controls, flux support belts and flux recovery units.
The AGW straddles the tank shell plates, riding on serrated steel drive wheels that can be adjusted for tank diameter.
The AGW's operator platform is a sturdy and solid workstation with guardrails and all-weather curtains for operator safety and comfort. The double platform is fully equipped with its own direction and speed controls. An access ladder allows movement to the primary flux separator tank and to the side of the dual unit.
The Koike Aronson / Ransome VUP single pass automatic welding system delivers faster, consistent, x-ray quality vertical welds on field erected storage tanks and other applications.
The VUP can handle vertical joint welding on plates 3/8" to 1" thick 6' to 10' high. With the optional oscillator, plates from 1-1/4" to 2" can be joined together.
The VUP's power supply consists of a skid-mounted Lincoln® DC-1000 with NA3 control and water flow panel.
The standard Lincoln NR-431/NR-432 Innershield® Processes offer significant savings, providing deposition rates of 48 lbs./hr.
The VUP is also ideal for other applications, including shipbuilding and manipulator-mounted butt-welding of 6' to 50' vertical plates.
The VUP's sturdy mainframe features a vertical column mounted on a carriage and roller assembly that rides on the top of tank plates. Its self-locking gear reducer with variable speed drive is electronically integrated with the welding control, which automatically adjusts speed to maintain the optimum copper-shoe-to-weld puddle relationship.
The lift controls include an up/down switch, low/high speed potentiometers and rapid speed selector.
Requiring just one operator, the VUP can complete 10 to 12 vertical seams per work shift.
Options available are water re-circulating system, power lateral travel, nozzle oscillator for plates 1-1/4" to 2" thick, electrical other than 230/460-3ph-60Hz, or other-than-standard wiring, and wiring for cable spans longer than 200' (61 meters).
Portable Track-Guided VUP Welding System
The Track-Guided VUP is a versatile, easy-to-use, easy-to-set-up system for in-plant vertical-up applications. It is ideal for accurate seam welding of gaped square butt and single vee-welds on plates from 3/8" to 4" and up to six feet in height. Additional track is available in six-foot heights.
The VUP consists of a vertical track, a powered carriage with special Lincoln nozzle, oscillator for plates up to 4" thick, water-cooled copper dam, nozzle and seam cross, and in-out adjustment. It features the Lincoln LN9V or NA5 solid-state control and wire feeder with 50 lb. reel. This model is wheel-mounted for in-plant mobility.
All parameters can be preset to monitor current, voltage and wire speed. A copper dam is automatically maintained in a fixed relation to the weld puddle. A flow regulator along with a switch in the water cooling circuit protect against no- or low-flow.
The Lincoln DC-1000 power supply features multi-conductor cables to supply control functions and 25' of double 4/0 ground cable standard. Assembly includes water hoses, wire feeder pressure rolls and inlet/outlet guides for either 3/32" or .120" diameter wire fed through 15' conduit.
Options include a water re-circulator cooler system, skid for power supply and water re-circulator, wiring for other-than-standard or 50Hz, and additional track for welds taller than six feet.
