Brazing Solutions

This is a twin station fixture that is typical of the type of machine used for brazing welding torches and oxyacetylene cutting torches. The parts to be brazed consist of brass bodies and heads with either brass or stainless steel interconnecting gas tubes.  The use of two heating stations allow one part to be heated whilst the other is cooling, or being loaded/unloaded. 

The induction heater seen here on the right hand side, can be positioned up to 100 metres (100 yards) away from the brazing fixture if required.  This two station system makes full use of the induction heater.  Whilst a group of components are being induction heated, the other group is being loaded/unloaded.The PLC diverts the heating energy from one work coil to the other and as the whole system is under PLC control, the heating times and powers etc. can be set so as to allow different sized components to be brazed on each half of the fixture.  For instance, a tube may have different fittings at each end.  The first end can be brazed in the first coil assembly and then the parts can be transferred to the second coil to have the other end brazed.  This of course provides true inline production.

This photograph shows several mineral insulated, stainless steel, sheathed data communication conductors being brazed into a stainless steel disk.  The completed assembly is typical of a high vacuum "lead through".  The vacuum brazing method is used to create very high integrity joints and as the joint is made without the use of flux, the problem of flux entrapment within the joint is totally eliminated.

This photograph shows the simultaneous brazing of 10 assemblies.  These particular components are for use in the automotive industry, however the general arrangement is typical of that used for multiple brazing.
