Orbital Welding
Cleanrooms are used in the orbital welding industry to provide a controlled, particulate-free environment essential for high-purity piping and tube fabrication. By eliminating atmospheric contaminants and moisture, these environments ensure the integrity of golden welds required for semiconductor gas lines, aerospace fuel systems, and pharmaceutical processing. Maintaining a sterile atmosphere prevents oxidation and microscopic defects, guaranteeing the safety and reliability of critical fluid and gas delivery systems.

Standards, Certifications, and Control Measures
- ISO 14644-1: Specifies the maximum allowable concentration of particles in the air and outlines testing and monitoring procedures to ensure air cleanliness in cleanrooms and controlled environments.
- Federal Standard 209E: Stringent cleanroom standard outlining air cleanliness standards federally.
- CFR Title 21 Part 211: Outlines the current good manufacturing practice (cGMP) requirements for cell and gene therapies. It covers all aspects of manufacturing, including facility design, equipment validation, and documentation.
- FDA Guidance for Industry - cGMP for Phase 1 Investigational Drugs: This guidance document provides recommendations for the manufacture of investigational drugs for use in Phase 1 clinical trials. It covers topics such as facility design, environmental monitoring, and personnel qualifications.
- EMA Guidelines on GMP Specific to Advanced Therapy Medicinal Products: Requirements for the manufacturing of advanced therapy medicinal products, including cell and gene therapies.
- WHO Guidelines on GMP for Biological Products: Recommendations for the manufacture of biological products, including cell and gene therapies. They cover all aspects of manufacturing, including facility design, equipment validation, and documentation.
It is important to note that these standards and regulations are not exhaustive, and additional guidelines may apply depending on the specific product being manufactured and the regulatory jurisdiction in which it is being produced.
Cleanrooms can be certified by a third party in many ways. Some common options include:
- Particle counting: Measures airborne particle concentration using laser particle counters.
- Airflow velocity measurement: Measures airflow velocity using an anemometer or similar device.
- Filter Integrity test: Ensures the filter does not have pin holes that could be compromising the overall performance.
- Smoke studies: Introduces smoke to observe airflow movement and design.
- Pressure differential measurement: Measures pressure differential to ensure proper isolation from outside contamination.
To maintain the standard of this certification, a cleanroom should be checked – at 6 month intervals for ISO 5 and 12 month intervals for ISO 6 and above – using the same or similar methods to the certification process.
- Use of appropriate personal protective equipment (PPE)
- Establishment and maintenance of a cleanroom environment that adheres to standards and regulations
- Implementation of proper cleaning and disinfection procedures
- Proper handling and storage of materials and equipment
- Proper cleanroom balancing to maintain positive cascading pressure (from the main cleanroom to the anterooms then to the outside)
- Regular monitoring and testing of the cleanroom environment to ensure continued compliance and minimize the risk of contamination.
