Purity Orbital Welder

Job Description

Sieber Industrial Contractors, a Talica Group company

Job Type: Full-time, on-site

Company overview:

Sieber, part of the Talica Group, provides precision fabrication and fabrication-related services for high-purity and hygienic industries, including pharmaceutical, biotech, and specialty food/beverage. We design, assemble, and commission sanitary piping and vessel systems that meet strict industry standards and customer specifications. This role focuses on high-purity orbital welding for cleanroom and process piping environments.

Position summary:

We are seeking an experienced High Purity Orbital Welder to join our fabrication team in the Wilmington area. The ideal candidate will have a proven track record performing high-purity orbital TIG welds on sanitary stainless steel tubing and fittings, with a strong commitment to quality, traceability, and cGMP/compliance. This on-site role requires excellent technical skill, attention to detail, and the ability to work safely in cleanroom and controlled environments.

Key responsibilities:

· Perform high-purity orbital TIG welding on sanitary piping (304/316/316L, Hastelloy and related alloys) using approved welding procedures and equipment.

· Set up, adjust, operate, and maintain orbital welding equipment; verify process parameters meet WPS/PQR requirements and project specifications.

-Read and interpret isometric drawings, P&IDs, process specifications, welding procedure specifications (WPS), and quality records; document welds with traceability.

· Prepare joints and fit-up, clean surfaces to required cleanliness levels, and maintain passivation and surface finish requirements per client/spec. (e.g., Ra targets and standard surface finishes used in high-purity systems.)
-Conduct pre-weld cleaning, fit-up checks, leak testing (e.g., helium leak tests), and post-weld inspection; perform nondestructive examination as required (e.g., dye penetrant/pressure tests).

· Ensure compliance with cGMP, FDA/ISO guidelines, ASME BPVC Section IX weld qualifications, and ASME BPE guidelines as applicable.

· Document weld maps, welder qualifications, batch records, and any deviations; maintain accurate QA/QC records for traceability.

· Troubleshoot weld defects, implement corrective actions, and participate in root-cause analysis and continuous improvement activities.

· Maintain and calibrate welding equipment and related tools; perform routine preventive maintenance and inventory control for filler metals and consumables.

· Coordinate with engineers, QA, and project teams to support on-time project delivery; participate in safety programs and maintain a clean, organized work area.

· Travel to client sites or job locations as required (occasional, up to a moderate percentage of time depending on project needs).

Required qualifications

· 3–5+ years of practical experience performing orbital welding on high-purity sanitary piping and vessels; biotech/pharma, food & beverage, or related clean-process environments preferred.

· Demonstrated proficiency with orbital TIG welding equipment and process parameters; ability to interpret WPS/PQR, drawings, and P&IDs.

· Knowledge of or experience with ASME BPVC Section IX weld qualifications and ASME BPE guidelines; familiarity with FDA/cGMP requirements and cleanroom protocols.

· Ability to work in cleanroom environments, with appropriate PPE, and maintain stringent contamination-control practices.

· Strong attention to detail, hand-eye coordination, and manual dexterity; good problem-solving and communication skills.

· High school diploma or equivalent; technical/structural welding training or an associate degree in welding technology, industrial maintenance, or related field preferred.

· Certification or demonstrated qualification as an orbital welder is highly desirable.

Preferred qualifications

· Prior experience with surface finishes and passivation processes relevant to high-purity systems.

· Experience with non-destructive testing methods (dye penetrant, pressure tests) and leak testing procedures.

· Valid welding certifications (AWS or equivalent) and/or ASME/BPE-specific welder qualifications.

· Ability to read…
