The CADWELD
®
process is a method of making
electrical connections of copper to copper or
copper to steel in which no outside source of
heat or power is required.
In this process, granular metals (granular copper
oxide and aluminum) are dumped from a container
into a graphite crucible and ignited.
The reduction of the copper oxide by the aluminum
(exothermic reaction) produces molten copper and
aluminum oxide slag. The slag floats to the surface
and the disk melts, allowing molten copper to flow
into the weld cavity and complete the weld. The
weld is allowed to solidify. The mold is removed
and made ready for the next weld. The process
takes seconds to complete.
BEFORE WELDING: READ, UNDERSTAND
AND FOLLOW ALL SAFETY INSTRUCTIONS
