Pin Brazing for Cathodic Protection Applications - A Beginner's Guide

Pin Brazing is ideally suited for many applications including continuity bonding between pipes, across flanges, connection of cathodic protection test and current carrying cables and connection of bracelet galvanic anodes etc.

The Pin Brazing equipment is very robust, easy to operate, easy to maintain and ideal for on site works.

The kit is powered by a 36V DC battery pack (or suitable welding generator when using the generator gun) capable of delivering 240A for use with fused brazing pins, ceramic ferrules and cable lugs.

With the earth device in place the gun trigger is depressed and after approximately 1.5 to 2 seconds the circuit is mechanically broken as the fuse wire breaks, and the brazing pin is held into the molten pool of brazing alloy that rapidly cools into a homogenous and very strong connection.

This short video demonstrates the three key steps to applying a successful pin braze to a structure for cathodic protection cabling.

The video has been presented in slow motion to better highlight each of the processes.
