FurseWELD Introduction
TSC-0912 - 09.10.12
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. Details of the SureSHOT system can be
found on pages 160-161.

Making a FurseWELD joint is a simple procedure as illustrated below:
1 Locate the
conductors (A) to be
joined in the weld
cavity (B) and close
the mould (C).
2 Locate the steel
retaining disc in the
base of the crucible (D).
Pour in the weld
powder (E) followed by
the starting powder (F).
Ignite starting powder
with a spark gun.
4 The molten copper alloy cools to leave a
fusion weld of great mechanical and
electrical integrity.
3 The resulting exothermic
reaction reduces the weld
powder to molten copper
alloy which melts the
retaining disc and flows
into the weld cavity where
it partially melts the
conductors (G).
