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...

Successful Pin Brazing
The key to successful Pin Brazing as with traditional Brazing techniques relies upon many key factors and there are several main factors, but when it comes to Pin Brazing there are just five areas on which we primarily focus when providing training classes or presentations. These are Power Supply, Surface Preparation for your connection, Surface Preparation for your Earth Device, having the correct Adjustment Setup and finally Operator Proficiency. 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...

Cadmium Free Pin Brazing
Today Pin Brazing is a widely used and versatile Electrical Bonding process, from Railroad to Offshore and Earthing to Utilities. Cadmium-free silver brazing filler metals were developed back in the 1940’s and all early Brazing Pins contained filler metals which were Cadmium-free, but in recent years these have become less widely used by other Pin Brazing Manufacturers in favour of Brazing Pins containing Cadmium Bearing Alloys and mainly distributed throughout the Pipeline Industry due to their lower working temperatures and compatibility with Pipeline materials...
