Case Study: Contamination-Free Orbital Welding for Semiconductor Facilities
A semiconductor fabrication plant in Southeast Asia required ultra-clean orbital welding for its high-purity gas delivery systems. The project demanded mirror-like internal weld beads, minimal heat-affected zone, and full traceability of every joint. Hyzont's cleanroom orbital seam welder (Model CHF-45) was selected for the task.
Challenge
- Welding 38-114 mm electropolished stainless steel tubing in cleanroom environment
- Zero contamination and oxidation inside the weld zone
- Strict documentation requirements for semiconductor industry audits
- Continuous operation with high duty cycle
Solution
The CHF-45 cleanroom orbital seam welder features a water-cooled welding head that maintains stable temperatures during continuous operation, ensuring consistent weld penetration on every joint.
| Tube Diameter Range | 38 - 114 mm |
| Welding Process | TIG Fusion with Orbital Rotation |
| Cooling | Integrated Water Cooling System |
| Gas Purging | Automatic Pre/Post Purge Cycles |
| Environment | Cleanroom Compatible Design |
Results
- Weld bead internal profile met SEMI standards on first inspection
- Oxidation-free joints verified by borescope inspection
- Data logging provided complete traceability for every weld
- Project completed 2 weeks ahead of schedule
The semiconductor facility continues to use Hyzont cleanroom welders for all new tool installations and facility expansions.
The Importance of Clean Welds in Semiconductor Gas Systems
In semiconductor manufacturing, process gases must remain ultra-pure. Any contamination in welded joints can introduce particles, moisture or oxygen that degrade wafer yields. Orbital welding with proper gas purging produces smooth, crevice-free internal weld beads that minimize particle entrapment and outgassing. The water-cooled welding head allows continuous operation without overheating, maintaining consistent weld quality even during extended production runs.
Comprehensive Weld Documentation
- Every weld joint is automatically numbered and recorded
- Welding parameters such as current, voltage, travel speed and gas flow are logged
- Data export via USB for quality assurance records and client reporting
- Real-time monitoring alerts operators to any parameter deviation
