Vacuum brazing and soldering

Outline

This is brazing and soldering using a vacuum furnace. Flux is not used, so processing to eliminate the flux is unnecessary. Brazing is performed in a high vacuum, making possible a highly clean brazing without coloration. Further, joining of layer with high dimensional accuracy and airtightness is possible.

Applications

• Upper electrode plates for semiconductor manufacturing device
• Pneumatic pressurizer parts
• Heat exchangers for helium liquidation in linear motor cars
• Mass flow controller parts

Characteristics

• Complex internal liquid or gas flow paths can be configured in three dimensions. Multiple joins can be made simultaneously.

• Multiple joins can be made simultaneously.
• Flow paths with low airtightness at the helium leak level can be manufactured.
  
• We can handle all areas consistently, from materials designation to mechanical processing, joining and surface processing, etc.

Specifications

Joining base metals: It is possible to join stainless steel, heat-resistant alloys, steel, and aluminum alloys.
Piece size: Manufacturing is possible up to device parts of Ф400mm.

Equipment Possessed

Large vacuum furnace

Electron beam welding

Outline

Electron beam welding is a method of welding that creates an electron beam in a vacuum, and methods metal by aiming the electron beam at the object to be welded. As the power density is extremely high, the melting band is narrow, enabling deep melding to be obtained. Further, as welding is performed in a vacuum, there is no contamination from the air, such as oxidation or nitriding.

Applications

• Welding metals with high melting point (Tungsten, Tantalum, etc.)
• Welding metals with high thermal conductivity (Aluminum, Copper, etc.)
• Welding dissimilar metals

Characteristics

• The melting band is narrow, enabling deep melding to be obtained.
  
• The thermal effects are small, enabling warping during welding to be suppressed to a minimum.
• Enables metals with a high melting point to be welded, and metals with high thermal conductivity to be welded.
• As welding is performed in a vacuum, there is no oxidation or nitriding to the welded parts.
• We can handle all areas consistently, from materials designation to machining, bonding and surface processing, etc.

Specifications

• Acceleration voltage: 150kV
• Electron beam current: 100mA
• Electron beam output: Max. 15kW
• Table size: 400 x 420
• Moveable range: 380(X) x 380(Y)
