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
