Electron Beam Welding (EBW) Business

Clean processing is possible for machining in a vacuum! High-precision welding with minimal distortion.

Our company acquired all of the electron beam welding equipment business from NEC Platforms, Inc. in August 2020, and we are engaged in the design, manufacturing, sales, and maintenance of electron beam welding machines, as well as contract processing for electron beam welding. Electron beam welding machines perform high-quality welding by accelerating electrons in a vacuum and irradiating them onto specific areas of the workpiece. The electron beam welding process is not a thermal conduction process. It directly melts the necessary parts with electrons. As a result, machining with extremely low thermal distortion is achieved compared to conventional welding methods. [Features] - High-precision welding with minimal distortion due to high-density heat source welding - No oxidation of the welded parts due to welding in a vacuum - Very high heat source efficiency (approximately 85%) *For more details, please refer to the PDF materials or feel free to contact us.

basic information

【Features of the Electron Beam Welding Machine】 ■ High-performance electron gun with a high degree of beam focus and a long focal depth ■ High-quality and high-precision welding can be performed quickly due to the high power density of the electron beam ■ The acceleration voltage and beam current can be independently adjusted, allowing for stable welding from ultra-thin sheets (25μm) to thick plates (100mm: 30KW) *For more details, please refer to the PDF document or feel free to contact us.
