Specialty Orbital Welder – High-Purity Process Piping

RTW Industrial Specialties, Inc. is seeking experienced Traveling Specialty Orbital Welders for high-purity and hygienic process piping projects supporting the pharmaceutical and biopharmaceutical.

This is a specialty craft position for experienced orbital welders. Candidates must have hands-on experience with automatic orbital GTAW welding in sanitary/high-purity environments and be prepared to complete project-specific qualification testing.

Required Experience

• Automatic Orbital GTAW welding
• High-purity and/or hygienic process piping
• 316 stainless steel
• Pharmaceutical, biopharmaceutical, food-grade, or comparable sanitary process environments
• Tube preparation, facing, precision fit-up, and alignment
• Closed-chamber orbital weld-head setup and operation
• Purge setup, oxygen control, and contamination prevention
• Weld programs, production coupons, and weld-quality requirements
• Reading WPSs, isometrics, P&IDs, and piping drawings
• Weld documentation, weld maps, logs, and material/heat-number traceability
• Ability to meet project-specific weld qualification requirements

The applicable high-purity specification prioritizes automatic orbital GTAW and requires orbital welding operators to be qualified in accordance with ASME Section IX. 

Specialty Alloy Experience

Experience with the following materials is highly desirable:

• 316 Stainless Steel
• AL-6XN (UNS N08367)
• Alloy 22 (UNS N06022)
• Alloy 276 (UNS N10276)
• Alloy 625 (UNS N06625)

These specialty materials are specifically identified within the hygienic piping specification for high-purity applications. 

Experience with AL-6XN and high-nickel alloys is a significant plus.

Preferred Qualifications

• ASME Section IX orbital welding qualifications
• ASME BPE experience
• Pharmaceutical/biopharmaceutical construction experience
• High-purity water and clean-steam systems
• CIP/SIP systems
• Sanitary process piping
• Experience working under stringent QA/QC and documentation requirements

Travel & Work Requirements

This is a traveling position supporting projects primarily throughout the Southeastern United States, with additional U.S. travel possible based on project needs.

Candidates must be willing to work project-based schedules, including overtime, weekends, shutdowns, and extended assignments away from home.

Engagement Opportunities

Qualified candidates may be considered for W-2 employment or independent contractor/business-to-business opportunities where the engagement qualifies for independent contractor classification. Engagement structure, compensation, per diem, travel arrangements, and project schedule will be communicated for each assignment. 

To Be Considered

Applicants should provide a résumé or detailed project history showing orbital welding experience, high-purity/pharmaceutical or food-grade experience, materials previously welded, orbital equipment operated, certifications/qualifications, and travel availability.
