Laser Brazing

Laser brazing is comparatively a new brazing technique in the world of brazing. It provides a suitable platform for the joining of the materials which pose difficulty to braze. Compared to other brazing processes, laser brazing offers a suitable possibility to decrease the working temperature and to join the un-brazeable material compositions. The joints produced are very strong and are characterized by a smooth surface and seams with almost no pores. Thus laser brazing has the benefit of conventional brazing and laser welding.


Advantages of Laser Brazing

• One of the major advantage of using laser into the brazing is the capability of selectively applying heat energy to small areas without heating the whole section.
  
  
• It's other advantage is close control of heat input and the ability to position or locate the heat accurately.
  
  
• It also helps in controlling grain structure and inter-metallic formations.
  
  
• Due to its centralized and localized heating it is capable of making joints near the thermally sensitive connections, such as in the production of miniature and thin precision parts.

Disadvantage
Perhaps the only disadvantage of laser brazing is the high cost of laser equipment. This method is used only when all other brazing methods are not found to be adequate.

Industries
In recent years it has become widely accepted as a reliable joining technology for visible joints in a number of industries like:

• Automobile
• Tool Making
• Ceramic to Metal Joining
• Refrigeration and Air Conditioning
