basic information

**Microplasma Welding Method** The microplasma welding method we use was developed by the Swiss company Seschillon (now OERLIKON) in response to the need for equipment development at the European Organization for Nuclear Research (CERN). It is a highly airtight technology, and our founder has applied and developed the welding philosophy and techniques learned during training in Geneva, Switzerland, for over 40 years to reach the present day. **Customer Feedback** Thank you for your cooperation in shortening the process and improving quality, from the production of welded pipes to the manufacturing of flanges, assembly processing, and helium leak testing after assembly. ● For more details, please contact us or download the catalog.
