Soldering and Brazing

Soldering and Brazing are joining processes where parts are joined without melting the base metals.  Soldering filler metals melt below 840 F.  Brazing filler metals melt above 840 F.  Soldering is commonly used for electrical connection or mechanical joints, but brazing is only used for mechanical joints due to the high temperatures involved.

Soldering and Brazing Benefits

  •  Economical for complex assemblies
  •  Joints require little or no finishing
  •  Excellent for joining dissimilar metals
  •  Little distortion, low residual stresses
  •  Metallurgical bond is formed
  •  Sound electrical component connections

Soldering and Brazing Issues

We can help optimize your joining process variables. Evaluate your current joining parameters and techniques.  Help eliminate common joining problems and discontinuities such as those listed below: 

Soldering and Brazing Joining Problems

  •  No wetting
  •  Excessive wetting
  •  Flux entrapment
  •  Lack of fill (voids, porosity)
  •  Unsatisfactory surface appearance
  •  Base metal erosion

If your company is experiencing these or other soldering or brazing problems you can engage us to improve your soldering or brazing processing.  Hire our consultant to act as your soldering or brazing specialist.
