Job Description

The CHW X-Ray Welder is responsible for performing high-quality welding on chilled water (CHW) piping systems, meeting radiographic (X-ray) inspection standards. This position requires a high level of skill and precision in welding processes (typically GTAW/TIG, SMAW/Stick), with a focus on weld integrity, cleanliness, and adherence to industry codes such as ASME and AWS.

Key Responsibilities:

Interpret and follow detailed welding procedures, blueprints, piping isometrics, and technical drawings specific to CHW systems. Perform welding on chilled water piping systems (typically carbon steel or stainless steel) in accordance with X-ray (RT) quality standards. Execute welds using TIG, Stick (SMAW), or other required processes depending on material and code specifications. Conduct root pass, hot pass, fill, and cap welds ensuring complete fusion and minimal defects. Ensure all welds meet or exceed standards for radiographic inspection (ASME Section IX or project-specific criteria). Conduct or assist in pre-weld preparation including fit-up, alignment, and tacking of pipe joints. Maintain traceability of welds, including proper marking and weld log documentation. Participate in non-destructive testing (NDT) processes, including X-ray inspection coordination. Follow all site-specific and general safety procedures, including use of PPE and hot work permits. Maintain welding equipment, tools, and work area in clean and safe condition. Collaborate with QA/QC inspectors, foremen, and engineers to resolve weld-related issues. Support pressure testing and flushing of CHW systems as needed.

Requirements:

High school diploma or equivalent; trade or technical school preferred. Minimum 3-5 years experience as a welder in industrial or HVAC mechanical piping environments. Proven experience in X-ray quality welding on CHW or similar process piping. Certified welder per ASME Section IX, AWS D1.1, or project-specific WPS (Welding Procedure Specification). Ability to pass required weld tests for radiographic standards (6G, 5G, etc.). Strong knowledge of pipe materials, joint configurations, and welding metallurgy. Experience with safe rigging, lifting, and handling of pipe and fittings. Excellent hand-eye coordination, attention to detail, and manual dexterity. Able to read and interpret welding symbols and piping specifications. Familiarity with OSHA safety regulations and mechanical piping codes. Willingness to work in confined spaces, at heights, or under adverse conditions.

Preferred Qualifications:

Current or prior certification from a recognized body (e.g., ASME, NCCER, AWS). Experience working on large-scale HVAC or industrial piping systems. Familiarity with pre-fabrication shop and field welding environments. Valid OSHA 10 or 30 certification. Understanding of QA/QC documentation and turnover packages.

Work Conditions:

Work may be performed in both shop and field environments. Exposure to high heat, noise, confined spaces, and elevated work areas. Must be able to lift up to 50 lbs and perform physically demanding tasks. Work may require overtime, weekend, or night shifts depending on project needs.
