Introductions:

LEDWELD exothermic welding is a simple, efficient, high-quality and self contained method for connecting metal conductor. The compact process requires no external power or heat source making it highly portable and easy to use. LEDWELD exothermic welding process is achieved by pouring superheated molten copper alloy (approximately 3000°C) on and around the conductors to be connected according to the aluminothermy process (2Al + 3Cuo--------------3Cu + Al2O3). The reaction is controlled within a graphite mould and it only takes a few seconds. Generally, one single mold has a life-expectancy of 50 times (up to 100 times if appropriately maintained).

Applications:

The LED exothermic welding is widely used and applicable for welding connection type illustrated as following:

 

Electronic Igniter

Insulated gloves

Mould clean shovel

Mould clean brush

Card torch

Steel disc

Packing and shipping:

Weld metal shall be pre-measured, packaged and sealed in tamper-proof containers to prevent spillage during shipping. Integral weld metal cups shall be packaged in be moisture resistant, recyclable containers.
