Brazing

Brazing is the joining of two or more metallic parts by heating them to high temperature and adding a filler material into the joint between the parts.   Induction heating is used to heat the parts to be joined until the brazing alloy melts, creating a bond between the metals.  A properly fitted and brazed part can have a strength close to that of the base metals.  The melting point for the braze alloy typically ranges from 1000F to 1500F depending on its' metallurgy, particularly silver content.

It is important that the parts to be brazed are brought to temperature uniformly and cleanly to produce the best braze joint. Heat Station induction  heaters,  with the right heating coil,  provide consistent, repeatable heating of  parts to maximize finished part quality and minimize operator skill required.  Magnefore Heat Station systems are used for brazing carbide to steel, diamond brazing, hydraulic tube fittings, and many more brass, steel, copper, carbide and stainless steel assemblies.

4 carbide inserts are brazed in place on to a steel base for a debarking tool.  Braze strips are placed beneath each carbide with flux. Heat time is approx 50 seconds using a HS5000R2 heater

A carbide insert is brazed to a steel carrier using a HS5000R2 heater. The coil is form at a 90 degree angle sothat the insert and the steel base are heated simultaneously.

A high pressure hydraulic fitting is brazed to a steel tube.  The spacing of the coil and the smaller diameter around the tube provide the correct heat pattern.

A completed braze joint for a hydraulic fitting.  The silver braze material flows through the joint by capillary action when the heating is right.

A cutter head is brazed to a steel shaft.  Heating time using an HS2500R2 heater is approx 10 seconds.

A stainless tube is brazed to a stainless steel sensor body. 

A large carbide insert is brazed to a steel base using an HS5000R2 heater using tri-met braze strips ,

The coil is formed to put the heat at the braze joint.

A cutter head is brazed to a steel shaft.  Heating time using an HS2500R2 heater is approx 10 seconds.

3 carbide inserts are brazed into  an insert that is brazed at the same time to a steel drill bit carrier.

A carbide insert is brazed to a steel carrier.  The coil is angle to fit the heating fixture. A ceramic rod is used to position the carbide.
