This presentation is the DVD component of a self paced, competency based, learning package. Neither brazing nor so-called braze welding is a fusion process. They are more akin to the lead/tin soldering processes. Only the temperatures required are much higher. Accordingly the demonstration explains what the process is, how bonding occurs and the importance of cleaning when preparing the joint. The selection of rods, tips and flame settings for both braze welding and brazing are detailed. Temperature control is stressed as it is very important for a successful joint with either process. The demonstration concludes with a series of typical problems experienced by the learner.
Duration: 11 minutes.
