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 cop-
per 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 BURNDYWeld
®
process has been used
to weld materials other than copper for elec-
trical purposes. Materials welded include:
Stainless Steel
Columbium Brass
Copperweld® Plain Steel
Bronze
Nichrome V
Everdur® Niobium
Galvanized Steel
Kama
Chromax
Silcone Bronze Steel Rail
Cast Iron
Copper Clad Steel Cor-Ten® Monel
When welding to galvanized steel it is recom-
mended to resurface exposed bare steel.
The BURNDYWeld
®
connection is a molecu-
lar 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 electri-
cal conductor will melt before the
BURNDYWeld
®
connection when sub-
jected 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.
