TIG Welder

PRIMARY FUNCTION

Set-up and operate Tungsten Inert Gas (TIG) and automatic inert gas (plasma) weldingequipment to buttweld tube sections together. Grinds welds smooth; welds wear beadsutilizing automatic Tungsten Inert Gas (TIG) process and straightens tubes, all inaccordance with approved weld procedure specifications.

WORKING PROCEDURE

• Receives work instructions from supervisor
• Operates automatic TIG and/or electric arc welding equipment to buttweld tubing
• Places work into position on worktable, fixture, rotator, positioner, or where welding is to be performed
• Uses prescribed methods, procedures, gas flow and wire; visually checks predetermined settings as needed
• Manually advances, measures, marks and cut tube to per-order lengths using abrasive cut-off saw
• Grinds and polishes weld reinforcements smooth with stationary power grinder and/or hand grinder to close tolerances; uses hydraulic press to straighten tubes as required
• Checks I.D. of insulated feed tubes by inserting section of liner tube inside feed tube
• Uses automatic TIG process to weld wear beads on feed tubes; grinds wear beads to ring gagedimensions
• Welds beads on liner tubes; od polishes tubes as required
• Inspects own work in process, but work is subject to in-process and/or final inspection by others, measures, marks, identifies work, records production data, etc., as directed
• Responsible for performance of duties and for good housekeeping in immediate work area
• Cooperate with and receive assistance from other shop personnel in the performance of work functions
