Pipe Welder at Confidential Phoenix, AZ

Stainless Steel Pipe Welder

This role requires a highly skilled TIG welder with strong experience in stainless steel process piping and 6G welding. You will perform precise open-root butt welds on stainless steel pipe across various schedules, interpret technical drawings and welding symbols, and consistently produce high-quality welds in a clean shop environment. The position demands excellent hand–eye coordination, attention to detail, and the ability to work both independently and as part of a team on a variety of changing projects.

• Perform high-quality TIG (GTAW) welding on stainless steel pipe, including open root butt welds on Schedule 10 through Schedule 160 pipe.
• Execute butt welding of stainless steel pipe by properly beveling pipe ends, cleaning joint areas, and utilizing GTAW (TIG) techniques to achieve 100% penetration.
• Carry out open root butt welding on stainless steel pipe with appropriate root gaps and bevels to ensure full penetration and high-strength joints.
• Perform 6G pipe welding on fixed pipes positioned at 45 degrees, mastering flat, horizontal, vertical, and overhead weld positions within a single joint.
• Apply back purging techniques to protect the root side of welds with inert gas, preventing oxidation, contamination, and sugaring on stainless steel and other reactive metals.
• Set up and operate TIG torches (200 AMP or higher) and related welding equipment; when needed, utilize flux core and MIG processes for applicable tasks.
• Interpret and work from technical drawings, blueprints, and welding symbols to plan and execute accurate welds on pipe, stairs, ladders, and other fabricated structures.
• Select appropriate welding parameters, consumables, and techniques based on pipe schedule, material thickness, and service conditions, including high-pressure applications.
• Inspect welds visually and with basic measuring tools to verify alignment, fit-up, and weld quality, making necessary adjustments to maintain standards.
• Maintain a clean and organized work area, ensuring tools such as squares, levels, hold pins, and tape measures are used correctly and kept in good condition.
• Follow all welding safety protocols, including proper use of PPE, safe handling of equipment, and adherence to shop safety procedures.
• Collaborate with team members in both shop and field settings to complete projects efficiently while meeting quality and schedule requirements.
• Adapt to a variety of projects and tasks, including pipe welding, structural components such as stairs and ladders, and other custom fabrication work.
• Work consistent overtime as required, maintaining productivity and quality standards during extended hours.

• Minimum of 3–5 years of experience as a TIG welder, specifically working with stainless steel process piping and 6G welding.
• Proficiency in TIG (GTAW) welding on stainless steel, including thin-wall and heavy-wall pipe across multiple schedules (Schedule 10–160).
• Demonstrated ability in 6G pipe welding, welding fixed pipes at a 45-degree angle in flat, horizontal, vertical, and overhead positions.
• Strong capability in open root butt welding on stainless steel pipe, including precise joint preparation, fit-up, and full penetration welds.
• Hands‑on experience with back purging techniques using inert gas (typically Argon) to protect the root side of welds on stainless steel and other reactive metals.
• Ability to read and interpret technical drawings, blueprints, and welding symbols accurately.
• Excellent hand–eye coordination, manual dexterity, and attention to detail for precise weld control.
• Solid understanding of the metallurgical properties of stainless steel and related alloys as they apply to welding and joint integrity.
• Familiarity with welding safety protocols and consistent use of appropriate personal protective equipment (PPE).
• Ability to work both independently with minimal supervision and collaboratively as part of a welding and fabrication team.

• Experience welding 2-inch Schedule 80 stainless steel pipe and other high-pressure piping applications.
• Knowledge of industrial, plumbing, or high-pressure piping systems where…
