Brazing copper and copper alloys
Figure 1 Brazing takes place above 840 degrees F but below the melting point of the base metal.Source: CDA, Copper Tube Handbook. Four processes to consider when joining copper and copper alloys are mechanical couplings, welding, soldering, and brazing. Brazing is suitable for small parts... Read more...

The need to feed aluminum
Aluminum, especially thin-gauge, presents unique welding obstacles. Gas metal arc welding (GMAW) in particular presents challenges in wire feeding and selecting the right type of filler metal and equipment. However, several options can aid in effective aluminum welding. In its pure form,... Read more...

Phases, structures, and the influences of temperature
But phase changes can take place in many metals while still in the solid state. These phase changes are directly related to temperature and take place in the metal's crystalline structure. And while temperature is what controls these transformations, stress, cooling rate, and alloy or chemical... Read more...

Brazing copper tubing
This tool modifies copper fittings by making a shallow impression in the fitting wall, shortening the socket depth to 3/8 in. It should be used only for joints that will be brazed. Strength of Tube Joints Butt joints between copper tubes can be just as strong as the copper itself if... Read more...
