Making a FurseWELD joint is a simple procedure as illustrated below:
|
Locate the conductors to be joined in the weld cavity and close the mould.
|
|
Locate the steel retaining disc in the base of the crucible. Pour in the weld powder followed by the starting powder.
Ignite starting powder with a spark gun. The resulting exothermic reaction reduces the weld powder to molten copper alloy.
|
|
The molten copper alloy melts the retaining disc and flows into the weld cavity where it partially melts the conductors.
|
|
The molten copper alloy cools to leave a fusion weld.

| Moulds
The
FurseWELD system of exothermic welding uses moulds to contain the
exothermic reaction that creates safe and robust connections. Different
types of moulds are available, whose use depends on the requirements of
the project.
Graphite Moulds
Market leading FurseWELD graphite moulds are extremely robust and capable of producing over 75 connections each.
Mini-Moulds
FurseWELD
mini-moulds are a cost effective alternative to full-sized moulds,
especially where lower numbers of connections are required. They are
smaller overall, less robust and therefore lower priced. Care is
required in order to achieve similar service lives to full-sized moulds.
SureSHOT
The
FurseWELD SureSHOT system is a single-use ceramic mould supplied
complete with retaining disc and powders. It has been designed for use
in applications where only a few connections are required.
