Common applications include wave guides heat sinks and electronic chassis which have leak tightness or stringent EMI criteria. The primary advantage of aluminum dip brazing is the ability to join thin and thick sections in one or multiple areas of a part.
How To Braze Properly Metal Brazing Procedures Brazing Gas Supply Refrigeration And Air Conditioning
Resistance brazing is effective for joining relatively small highly conductive metal parts.
. For many dip brazes the dip process is completed by hand. Closed assemblies should allow easy escape of gases and in dip brazing easy entry as well as drainage of flux. The assembly is pre-heated to 1025F to ensure uniform temperature in dissimilar thicknesses and then dipped in a saltwater brazing flux at 1095F which quickly and evenly heats all of the components and melts the filler alloy bonding the pieces.
The filler metal should be in contact with the parts to be joined. Making use of the proper brazing sheets helps ensure a uniform temperature throughout the material during the brazing process while imbuing the final product with additional strength. Preheat at 985F Cycle time is dependent on mass and part configuration.
