Soldering and brazing
Consider the following scenario: You arrive at a job site and need to join copper pipe for a refrigeration system with operating pressures up to 600 psig.
Which method, soft soldering (sweating) or hard soldering (brazing), are you going to use to join the copper pipe? Why did you choose this method?
What must be done to the pipe to prepare it for joining using this method?
What other information should you know to perform a good solder joint?
Give an example where you would use the other type of soldering, and describe this soldering method using questions1-3 above

My first question for the discussion board pertains to Brazing and Soldering. HVAC technicians are masters of our craft. Brazing is a part of our craft. We will not be able to make you an expert in brazing here at college, because with all of the others skills that we need to teach you, we just cant allow you to come to class everyday and do nothing but brazing. You would miss out on a lot of very important skills that you need to be successful in this field. But in order to become well rounded, you must master the skills of brazing.
As we learned in our text book, Brazing is used to join copper to copper or copper to dissimilar metals. When brazing we use temperatures above 842 degrees, but most are joined with temperatures between 1200 and 1550 degrees. With that being said, brazing can be very hazardous to technicians, customers and property.
For our discussion, I want you to name all of the hazards that come along with brazing and then explain some the things that you can do to mitigate these hazards. The hazards include personnel, equipment and property.
