" The BURNDYWeld™ connection process is a simple, efficient method of welding copper to copper or copper to steel" One advantage is that NO outside power is required when using the BURNDYWeld™ exothermic process.
The BURNDYWeld™ process uses high temperature reaction of powdered copper oxide and aluminum.
The reaction takes place in a semi-permanent graphite mold.
These molds will last for fifty or more welds if proper care is given.
The reaction takes place very rapidly,
therefore the total amount of heat applied to the conductors or surfaces is
considerably less than that of brazing or soldering. It is important to remember
this when welding to insulated cable or thin wall pipe.
This system is very field friendly, since it is light and portable and
requires no outside power source. It requires very little time or skill to obtain
an efficient, maintenance free connection when using the BURNDYWeld™ process.
The move to lead-free is the most dramatic change to have occurred in
the connector industry, with repercussions throughout the logistical chain,
affecting all product lines and production platforms. To manage this change,
an FCI project team was formed, which used project management principles
and carefully selected guidelines to develop technologies in line with
customer requirements.
The BURNDYWeld™ connection is a molecular weld. The weld metal has the same melting point as copper.
These factors along with the increased cross section of the connection, BURNDYWeld™ connections:
1. Will not be affected by a high current surge. Tests have shown that the electrical
conductor will melt before the BURNDYWeld™ connection when subjected to high short circuit
current. Consult IEEE Standard 837-1989.
2. Will not loosen or corrode at the point of weld. There are no contact surfaces or
mechanical pressures involved. A BURNDYWeld™ connection becomes an integral part of the
conductor.
3. Have a current-carrying capacity equal to or greater than that of the conductors.
