Welding

TPI has a serious welding experience in TIG welding and Electron-Beam welding

  • RCC-M, RCCM-R and CODAP welding and welders qualifications........
  • CS, SQMOQ and SQS welding methods:
  • Cofrend 2 qualified controllers for penetrant testing:

 

TIG Welding

TIG-welding principle replaces the fusible wire by a non-consumable tungsten electrode retaining the advantage of protecting the welding zone under an inert gas. Since the electrode is not fusible, TIG welding implies filler metal.

A wide range of TIG welding units (up to 400A) are available at TPI

 

Electron Bean Welding

Electron-beam welding is a metal joining technique used to obtain high strength joints with minimal deformation of the assembled parts.

TPI uses 3 electron-beam welding machines

• Techmeta: 1 kW gun power with a 1.8 m3 chamber
o Moving table X-axis stroke  2200mm
o Able to perform circumferential welding
 
 
• Air Liquide: 10 kW gun power with a 1 m3 chamber
       o Moving gun X-axis stroke 300mm
       o Able to perform radical welding
 

• Techmeta : 15 kW gun power, with a 10 m3 chamber
       o Moving table X-axis stroke 2300mm / Y-axis stroke 500mm
       o Able to perform circumferential welding

Brazing

Brazing is an extremely versatile process, allowing to join a wide range of metals, whether ferrous or non-ferrous. Since brazing does not melt the base metal, it is ideal for joining metals with different melting temperatures.

TPI with its "Nicrobraz®" brazing chamber conducts under vacuum induction brazing on small parts, thus enabling the development of brazing processes.

TPI works together with CELES when developing the type of suitable of inductor a given brazing process.
