Each month the Copper Development Association of South Africa (CDAA) brings insight into the dos and the don’ts of copper soldering.
The following tips are there to assist the craftsperson to achieve lasting results.
Brazing is the second most commonly used method for joining copper tube. Making brazed joints is similar to making soldered joints with respect to measuring, cutting, reaming, cleansing, assembly, and support. And as in soldering, the brazing filler metal is melted by the heat of the tube and the fitting and is drawn into the joint by capillary action.
The major differences between soldering and brazing are:
- type of flux used;
- composition of filler metal; and
- amount of heat required to melt the filler metal.
