ABSTRACT
In modern brazing practice furnace brazing makes the greatest numbers of joints, but the greatest number of brazing applications are satisfied by flame heating.
The primary reasons for the popularity of flame brazing are:
1. It is a very flexible heating process. 2. A very wide range of fuel gases can be used. 3. Even relatively unskilled operators can produce acceptable results. 4. It is very easy to develop alternative heat patterns. 5. The equipment for flame brazing with a handheld torch is readily
portable. 6. Brazing on outside locations and within the workshop is easily
undertaken. 7. It can be used for applications that vary from simple one-off joints
made with a handheld torch to highly sophisticated automated brazing systems equipped with a series of specialized torches mounted in fixed positions where the output rate can be up to 4000 parts per hour.
