Orbital welding is the backbone of hygienic piping in pharmaceutical and biotech facilities. Repeatable heat input, consistent purge gas coverage, and qualified procedures are essential for ASME BPE compliance.
Every project should maintain WPS/PQR documentation, welder qualifications, and visual plus boroscope inspection records for critical joints. Traceability from heat number to isometric drawing gives QA teams confidence during audits.
Automatic orbital welding reduces variability compared to manual techniques, especially on repetitive loop installations. For tie-ins and complex geometry, certified manual welders remain essential — the quality system must cover both.
Midex welding teams work to documented procedures with full inspection records, supporting client turnover packages and ongoing maintenance traceability.
