Author: cuprobraze | Size: 1.91 MB | Format: PDF | Quality: Original preprint | Publisher: cuprobraze | Year: 2006 | pages: 110
Forewords
The CuproBraze brazing handbook is a way to share the latest knowledge regarding the CuproBraze process. It deals with technical questions in general. The CuproBraze process is rather young and developments in different areas are still on-going. Therefore, all recommendations in the handbook should be seen as advice, sometimes better or other ways to success can be found. The handbook will be updated from time to time and if there are any questions or other matters which should be included, please contact editors.
The handbook is based on the original manuscript of Leif Tapper, who has retired when this edition comes out.
