Brazing service and set-up new brazing processes:

       Our company provides the following brazing services: 

(a)   Vacuum brazing of metals including stainless steel, titanium, copper alloys and aluminum alloys,

(b)   Vacuum brazing of metals to ceramics including alumina, zirconia, silicon carbide,

(c)   Torch brazing of steels, copper alloys, and titanium.

Dimensions of parts to be brazed should be able to fit into the hot zone of our vacuum furnace (See Fig. 1). Maximum brazing temperature is 1250°C (2282°F). The furnace is equipped with a programmable controller, survey thermocouples and two view ports allowing a direct observation of the brazing processes. If requested, customers can receive a time/temperature record of the brazing cycle.

We also perform the service involved with development, testing and setting-up new brazing and soldering processes. This service includes:

 (a)  Consulting in design of brazed and soldered joints, as well as brazed assemblies;

(b)   Selection of brazing filler metals, solders, and fluxes,

(c)    Brazing or soldering of new materials,

(d)   Testing and evaluation of brazing and soldering processes,

(e)  Trouble shooting of existing processes in order to improve quality of products and strength of brazed and soldered joints,

(f)   Transition from laboratory runs to mass production of brazed and soldered assemblies.

 Testing of brazed or soldered joints includes:


  1. Shear and tensile strength testing according to AWS C3.2M/C3.2:2008 “Standard Methods for Evaluating the Strength of Brazed Joints”
  1. Bending tests of brazed or soldered joints
  1. Corrosion resistance of brazed or soldered joints according to:

-         ASTM G48-03 “Standard Tests Methods for Pitting and Crevice Corrosion Resistance of Stainless Steels and Related Alloys by Use of Ferric Chloride Solution”, and

-         ASTM G31-72 “Standard Practice for Laboratory Immersion Corrosion Testing of Metals”
