The reusable graphite refractory crucible (mold) consists of two chambers: the upper chamber for thermite reaction and the lower welding cavity.
The reaction occurs in the upper chamber after the welding material is ignited. The resulting alloy consists of molten copper and aluminum oxide. The alloy flows into the welding cavity and forms a reliable connection after hardening on the parts to be welded.
During the welding operation, the parts to be welded are placed inside the crucible, which then must be secured by a special clamp.
This crucible is designed for making multiple butt welded connections of 30x4 mm tapes.
The crucible inner surface must be cleaned from waste slag by special accessories after each welding operation.

Crucible clamp (clamping device)
The manual universal clamp securely fixes parts to be welded inside the crucible and prevents the molten alloy from flowing out.
A clamping device type 4 is required to make the butt connection of 30x4 mm tapes.
Charge (thermite powder)
Thermite is a powder mixture consisting of:
- A metal having a large oxidation heat value, such as aluminum, which is very active when combined with oxygen resulting in the easy recovery of other metals from oxides under certain conditions;
- A second metal oxide with a small formation heat value (e.g., copper or iron oxide).
When the thermite burns down it forms a molten metal, which fills the parts to be welded and forms a welded connection.
A charge weighing 0.115 kg is needed to make the butt connection of 30╤В╨е╨┤тХи╨е4 mm tape.
