The Differences Between Soldering, Brazing, and Welding

Brazing and soldering are commonly used as essential assembly techniques. Because you are working with a precipitation hardening alloy, temperature and heat time may be standardized and controlled. Welding is known to offer specific advantages that other structural alloys do not. This is especially the case for cold work strength. Welded joints made with copper beryllium typically retains 90% or more of the mechanical properties of the base metal. Common welding problems, such as surface depletion and sensitization, are not experienced when using this alloy. Each process works with straight and cut wire.

When the temperature is below 300 degrees Fahrenheit and the thermal and electrical conductivity is hard to ensure, soldering is the best option. Soldering is commonly used because of its performance with heating and resistance. It is also known to withstand induction, flames, and infrared. Typical application techniques include wave, immersion, vapor phase, and more. This process works well with plated wire.

When compared to soldering, brazing provides superior resistance and higher strength to thermal exposure when at moderately elevated temperatures. Brazing must be performed at relatively high temperatures, and it is common for brazing to be done before age hardening. When using a rapid brazing cycle, it is possible to join the alloy effectively.

Beryllium Copper

Welding is another useful joining process, but when welding, you must be careful with metallurgical planning. It would help if you took the time to consider joint design, weld technique, and post welding practices. You can resistance weld Beryllium copper wire by seam or spot welding. When necessary, ultrasonic and laser welding are performed.

  Copper alloys are known to tarnish and oxide when exposed to air. Tarnish will accelerate with the presence of high temperatures and moisture. Heat treatment typically causes oxidation. Keeping copper alloys clean and dry will help prevent this.
