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.

Company information
Nissei Kiko Co., Ltd. has been engaged in precision welding processing, primarily focusing on stainless steel foil materials (ultra-thin materials), for 40 years since the founder encountered 0.05 mm butt welding, with the motto of being a pioneer in precision welding. In addition to stainless steel, we also handle welding of pipes with butt joints of 1.0 mm or less in materials such as titanium, Hastelloy, and Inconel, and we provide contract processing for precision equipment parts, including vacuum devices, semiconductor manufacturing equipment, ultra-low temperature devices, fuel cells, and nuclear-related components, from welding to assembly. From prototype development with a single piece to batch production of several hundred pieces, we offer precision, accuracy, and sincerity with the nimbleness characteristic of a small factory.
