CE Certified Orbital Welding Machine: Technical Specifications and Compliance for Regulated Industries
CE Certified Orbital Welding Machine: Technical Specifications and Compliance for Regulated Industries
An orbital welding machine is a precision automated welding system that rotates an electrode around a stationary pipe or tube to produce consistent, high-quality welds. KEPUNI is a brand of Shanghai Chuanli Industrial Co., Ltd., a high-tech enterprise certified by the Ministry of Science and Technology of China, specializing in orbital welding machines, tube-to-tube sheet welders, open pipe welders, and related equipment. With CE certification covering multiple product lines, KEPUNI orbital welding machines serve regulated industries such as pharmaceutical, semiconductor, food & beverage, oil & gas, and chemical processing.
Why Certification and Compliance Matter in Industrial Orbital Welding
In high-purity and safety-critical environments, weld quality directly impacts product integrity, process reliability, and regulatory approval. Manual welding often introduces variability and contamination risks. Automated orbital welding addresses these challenges, but equipment must also carry recognized certifications to satisfy audit requirements. For buyers evaluating orbital welding machine options, CE certification demonstrates conformity with EU health, safety, and environmental standards, while industry-specific approvals (e.g., 3A, SEMI F57, ASME) provide additional assurance.

Step-by-Step Selection Guide by Industry Compliance Needs
- Identify pipe/tube dimensions and material – Determine outer diameter, wall thickness, and material (stainless steel, alloy). KEPUNI machines support steel and alloy materials.
- Match to industry certification – For semiconductor applications requiring SEMI F57 cleanliness, choose the XD-20PRO with 5H Series split weld head. For pharmaceutical WFI (Water for Injection) systems demanding 3A standards, the XD-20PRO with 10H Series is suitable.
- Select power supply type – The XD-20PRO and XD-20W power supplies cover OD up to 168 mm. For heavier-wall pipes (≥2.5 mm), the open pipe XD-K Series or girth welding XD-GH Series is required.
- Verify certification documentation – Request the CE certificate that matches your target market. KEPUNI provides certificates issued by UDEM and anbotek for the EU.
Real-World Project Results
Semiconductor Ultra-Pure Gas Piping (28nm Fab)
Four units of XD-20PRO Hi-Purity with tube-sheet heads were used for UPG distribution and DI water loops. Results: SEMI F57 cleanliness standard met, zero particle exceedance events, and uninterrupted FAB production.
Pharmaceutical WFI Pure Water System
Three units of XD-20PRO with weld heads were deployed for SS316L WFI piping and CIP/SIP lines. Results: 3A Sanitary Standard certification, zero contamination incidents, and 100% pressure test pass rate. The project also passed EU GMP audit on first attempt.
