WELDER GENERAL

Performs welding, burning, brazing, silver soldering (by arc or torch) as required in the work assignments of general maintenance trades (Electricians, Pipefitter, Machine Repair, Industrial Truck Repair, Millwrights and Carpenters).

WELDER TOOL & DIE

Performs welding, burning, brazing, silver soldering (by arc or torch) as required in the fabrication, repair and mainte­nance of dies and aids attached to dies, (such as lifters, kickers, chutes) fixtures, jigs and gauges in the Die Room (including fixtures and machine shop areas) and in Die Tryout.

WELDER REPAIR

1. Construct, maintain, tryout, and repair welding fix­tures (including original, reconstruction, modifica­tion, and engineering changes) used for production purposes (i.e. resistance, CO₂ (MIG) and arc welding processes). Such equipment shall include, holding, C-frame, press table top, piano, single point, over and under, and special fixtures. The foregoing processes will include fabrication of all fixture details, by any welding process available.
   
2. Construct, maintain, tryout and repair automation, (drop stops, transfer rails, kickers, extractors, ejectors, lifters, strippers, outriggers, idle stations, etc.) when the primary base mounting is to the welding fixture “C” frame platen or welding press platen. [Ref: Millwright #50 and Electrician #38]
   
3. Install, and/or remove welding fixtures, production aids, automation, conveyors, roller racks, and related equipment to facilitate change over of welding lines, utilizing required vehicles to accomplish equipment movement. Cycles and tryout the welding lines to secure Quality Control approval of parts.
   
4. Constructs and maintains hydraulic power unit on provided frame work. Maintains air packs. (Pipefitters initially install air valves on automation that is part of the stationary frame work). [Ref: Electrician #3, Millwright #21]
   
5. Installs, repairs, and maintains sequential welding timers, brain units, back panels, probe control panels, and electrical components such as wiring limit switches within the welding fixture, including removal and replacement of whips connected to hydraulic and air valves outside the fixture but control the welding process. Repairs maintains and adjusts welding timer panels and trouble shoots through aux­iliary panels.
   
6. Constructs, assembles and attaches Portable Welding Gun Accessory Trays (skirts or shrouds) to trans­former housing. (Hangs and try out completed unit on rail). Maintain portable welding gun installations. (Electricians connect and disconnect wires from power source to portable welding gun transformers, junction boxes, and install ground wire from the hanging welding gun transformers to building ground on new installations). [Ref: Electricians #6]
   
7. Performs preventive maintenance, weld checks for OK panels, trouble shoots, analyzes, checks and maintains hydraulic fluid levels on welding operations.
   
8. Install, remove, and make adjustments on I.S.I. extractors or transfers when in the welding fixture.
   
9. Replace valves on power packs.
   
10. Maintain and repair all equipment on index or “whirly bird” machines used for welding, locating, and unloading parts (examples: air cylinders, air probes, limit switches, and replacement of solenoid valves). Make necessary adjustments in Tool Control Center panel as necessary for weld schedule. [Ref: Electrician #26]
    
11. Load and unload welding fixtures entering and leaving the plant.
    
12. Trouble shooting new installation of welding fixture and guns with necessary corrections and cycling out for proper sequence with Electrician before equipment is released to Welder Repair for production. [Ref: Electrician #14]
    
13. Hang portable gun transformers.
    
14. Construct, maintain, tryout and repair production processing checking fixtures.
    
15. Adjust, replace and changeover induction welders and welding coils. [Ref: Electrician #1]
    
16. Perform welding related maintenance and repair to weld tool head mounted on robot, and make necessary “weld point” corrections. [Reference Electrician #37]
    
17. Perform related maintenance and repair to weld tool head mounted on robot, and make necessary “weld point” corrections (moving parts or welding guns) by manually stepping robot through the program.  [Ref: Electrician #14, #37 and Machine Repair #27]
    
18. Aim Vision systems in process checking fixtures. [Ref: Electrician #41]
