pieces was made this allowed the cuts to be made without the blade pinching from one long linear cut (this led to saving of time energy and blades) 4. once the piece was rough cut it was then fitted into a vice and ground with a 4-inch angle grinder to a relatively smooth finish 5. after the grinding process rounded edges were filed to a smooth transition (to prevent premature tearing during the testing process) What's the test specimens were cut and prepped for brazing and soldering the process began. Each piece was mounted in a vice and heated with an oxy acetylene torch until adequate temperature was achieved to get the solder or brazing medium to flow properly. What's the
proper temperature was achieved the solder or brazing medium was applied to the Joint thoroughly until no gaps could be seen between the two pieces being joined. This process was repeated for each specimen except for the Baseline specimens that require soldering or brazing. There was no label on this silver solder supplied by the school but as far as my research could find it would be a 5% silver solder alloy tables will be listed at the end of the report documenting this material The second Silver solder that I used was a plumbing silver solder made by BernzOmatic it was lead-free and had a Melting temperature of 430°F more Details will be listed at the end of the report with the rest of the reference material be providing. The last material used was 1/8-inch flux coated brazing rod made by Lincoln electrode they are described as malleable and are designed to fuse well with cast iron, galvanized iron, steel, brass and copper. A low fuming rod of the highest quality. Designed for high strength and wear resistance. Full details on this product can be found in the back of the report. The copper used was c11000 which is 99% copper and the brass that was used is C36000 free cutting brass / free Machining brass.
