University of Anchorage Alaska Metallurgy final project Report Weld A287 Metallurgy Eli Ringelenstein, Instructor Objective: to observe, document and report any and all findings from the experiment performed on copper and brass soldering and brazing tensile strength comparative testing. The goal of this scientific experiment would be to compare the tensile strength of solder, silver solder, and brazing of copper and brass. Four specimens would be prepared from each type

of material, one would be a standard tensile strength test specimen to give a baseline test of what the specimen is capable of, the remaining three specimens one would predominantly just be regular plumbing solder on a square 1-inch tensile strength test specimen, one would be silver soldered, and the last one would be braised. The ultimate goal of this is to compare the strengths of the three joining materials and to compare them to the relative strength of the base metal, as to my knowledge I have never heard nor have tried to tensile strength test any kind of soldering or brazing this would bring a wealth of knowledge and questions answered in my mind and I’m sure others. To start each piece was prepped in accordance with the template acquired from the instructor So that each sample was uniform and met the criteria for being put in the tensile test machine, an extra inch was added to each side of the test specimen for those that were brazed or soldered together (Attached at the end of the report will be pictures of samples and templates used). Each specimen had the paper template attached 1. the template was then trimmed and lines were scribed to follow while cutting on a bandsaw 2. quick cuts were made to the depth needed to trim the most material possible (a reference picture will be added at the end of the report) 3. once the quick lines were cut then one long line to detached the small individual tooth like
