• Experience welding Schedule 10, Schedule 40, Schedule 80, or heavier-wall piping as required.
• Ability to read and interpret piping isometric drawings and welding symbols.
• Knowledge of pipe preparation, fit-up, welding techniques, and quality requirements.
• Familiarity with applicable ASME welding codes and procedures.
• Ability to operate welding machines, grinders, cutting equipment, and other fabrication tools.
• Strong attention to detail and commitment to producing quality welds.
• OSHA 10 certification preferred.
• Ability to work independently and as part of a mechanical construction crew.

Preferred Experience

• Large commercial construction projects, including data centers, hospitals, universities, high-rise buildings, and manufacturing facilities.
• Central utility plants and large mechanical rooms.
• Chilled water, heating water, condenser water, and steam piping systems.
• Large-diameter carbon steel piping.
• TIG root and Stick fill/cap welding procedures.
• Stainless steel pipe welding and back-purging techniques.
• Pipe welding on chiller plants, boiler systems, and cooling tower installations.
• Experience with ASME B31.1, B31.3, or B31.9 piping requirements, as applicable to the project.
• Welding qualifications in accordance with ASME Section IX.
• Experience working with pipefitters on prefabricated piping assemblies and field installations.
• Experience with visual inspection, radiographic testing, ultrasonic testing, or other weld quality requirements.

Physical Requirements

• Ability to lift and carry up to 75 pounds.
• Stand, bend, kneel, crouch, and climb throughout the workday.
• Perform welding in overhead, vertical, horizontal, and restricted positions.
• Work from ladders, scaffolding, and aerial lifts when properly trained.
• Perform welding in mechanical rooms, elevated areas, and confined spaces when authorized.
• Work indoors and outdoors in varying construction conditions.
• Ability to work overtime, weekends, and extended schedules as required.

Project Information

• Large-scale commercial mechanical construction.
• Installation of HVAC, hydronic, and mechanical piping systems.
• New construction, expansions, and major facility upgrades.
• Field welding and pipe fabrication opportunities.
• Overtime opportunities based on project schedules.
• Competitive pay based on experience and welding qualifications.
• Per diem opportunities for qualified travelers, where applicable.
• Potential long-term project opportunities.

Ideal Candidate
