Titanium Line Operator LMA

Mission

• To chemically clean casting prior to inspection and reworking using alkaline baths, cold etch baths, and/or hot water washes; to accurately prepare, operate and maintain tanks used for chemical cleaning; to clean castings before routing to shipping.
• To complete all steps necessary for the application of fluorescent penetrant on castings in order to prepare castings for the fluorescent penetrant inspection process; to prepare castings for evaluation by the fluorescent penetrant system.

Objective: to test chemical baths, make corrections and assure conformance to process control specifications.

• Takes alkaline bath samples to determine concentration.
• Takes acid bath samples to lab; checks lab analysis to determine if bath chemistry within specification ranges; determines what additions are required.
• Calculates etch rate using standard formula.
• Adds acids to bath in order to bring chemistry up to specifications, using standard formulas; adds water to alkaline baths if out of compliance; adjusts surface tension as needed.
• Checks operation of and primes circulation pumps; checks for leaks; troubleshoots and reviews pumping diagrams if needed.
• Monitors and maintains chemistry of cold etch baths.
• Changes all filters/screens as required by schedule.
• Wears protective gear when working with chemicals.

Objective: to submerge parts in chemical tanks to clean according to specified procedures for further inspection and/or processing.

• Places fixtures on castings; submerges in alkaline and/or acid baths using hoists or tumblers.
• Removes castings, rinses and transfers to drying ovens; loads and unloads ovens.
• Completes hot water rinses as specified.
• Pumps spent tank solutions into drums and prepares them for transfer to neutralization facility; cleans and rinses tanks.
• Hand etches small parts as needed.
• Hand cleans castings of all markings prior to shipping.

Objective: to complete all steps in the preparation and application of penetrant to castings.

• Visually inspects castings for surface dirt; cleans and degreases as necessary.
• Chemically etches specific castings by local or swab etching, which removes a small amount of metal; neutralizes parts with water and dries; neutralizes holding tank.
• Places clean castings on penetrant line and applies fluorescent penetrant liquid using hand‑held, electro‑static sprayer; allows penetrant to be absorbed.
• Washes castings to remove penetrant after specified time; pre‑dries with fans and places castings in drying cabinets.
• Places castings in developing cabinet for automatic application of powdered developer.
• Visually inspects castings; cleans and degreases as needed.
• Wears protective gear during line operation.

• Completes logs and records, including alkaline concentration, bath etch rates, chemical additions, and part lots.

Objective: to maintain penetrant line equipment and work area in good working order.

• Performs maintenance and minor repairs on equipment.
• Keeps work area and materials clean and orderly.

Objective: to take responsibility for and demonstrate safe work practices.

• Adheres to plant and department safety rules.
• Safely operates all equipment and tools.
