Pin Brazing
Pin brazing is basically 'Drawn-arc Silver Brazing', considered a Brazing process and not (as is sometimes incorrectly stated) 'Electric-arc Silver Soldering', as the working temperature or melting point of the filler material is below that of the base metal or substrate but above 426.6 Degrees Celsius (800 Degrees Farenheit). The filler metal, in the case of Pin Brazing is a Silver alloy consisting typically - Ag 55%, Cu 21%, Zn 22% and Sn 2%, which when molten flows directly into the closely fitted surfaces between the desired connection type and the substrate material by Capillary Action... Read more | Online Publication

The above factors can often be overlooked individually, often creating inadequate results and expensive delays so it is important that both operators and companies ensure that they have either received or made provision for training and certification by qualified, experienced Instructors... Read more | Online Publication

Cadmium Free Pin Brazing
