Brazing Procedure – Practice Makes Perfect

October 21, 2011/0 Comments/in Medical Gas Training / by Cary Darden

As part of the ASSE 6010 Medical Gas Installer Course, proper brazing procedures are taught.

It is rare that an individual will braze a successful horizontal and vertical coupon on the first try.  Reasons for failure include:

-Improper sequence of feeding the rod into the coupling

– Improper amount of heat to cause the melted rod material to flow to the center of the coupling by capillary action, or the proper amount of heat in the wrong place on the coupling (i.e. the edge of the coupling is hotter than the center of the coupling).

– Improper position of the rod while feeding it into the coupling.

– Improper position of the torch while heating the coupling/piping assembly and while feeding the rod into the edge of the coupling.

– Improper amount of rod being fed into the edge of the coupling (not enough rod to fill the coupling).

-Improper amount of time spent doing the coupling.

We recommend practicing the procedure prior to attending an exam session. We offer a DVD of the brazing procedure, available in English or Spanish, for $20.00 plus applicable taxes and shipping costs. We can send a DVD to you at anytime.

EMGS has an almost perfect pass rate for students taking the practical brazing exam, and this is directly related to our method.  Please contact us at 770-459-5920 if you wish to become certified to install medical gas, or would like to order a DVD on the correct brazing procedure.
