Exothermic Welding

Introduction

Exothermic welding, also known as exothermic bonding, thermite welding, and thermit welding, is a welding process that employs molten metal to permanently join the conductors. The process employs an exothermic reaction of a thermite composition to heat the metal, and requires no external source of heat or current.

Exothermic welding is a cost efficient method of making large or small numbers of high quality electrical connections.

Moulds

Exothermic welding uses moulds to contain the exothermic reaction that creates safe and robust connections.

Power Cartridges

Exothermic Welding Powders are a high quality mixture of copper oxide and aluminium – the starting powder is compacted at the bottom of each cartridge with the weld metal on top.

Accessories

Handle clamps enable the mould to be handled when hot, and the two halves of the mould to be opened and clamped together.
