Exothermic welding material is the electrical connection by using the method of an Exothermic Reaction process. Exothermic welding, also called Thermit welding makes use of the following two indispensable applications - - 'weld metal powder' and 'semi permanent graphite mould' or 'ceramic mould' (one time mould).
Exothermic welding material is mainly used for electrical connectors especially in electrical grounding/earthing, lighting protection etc. It is categorized as grounding/earthing material as grounding/earthing bonding.
WELDING POWDER COPPER is the high quality welding powder that has been used in several major projects. The TECHWELD powder is packed in a tube with different sizes to choose for different welding moulds. The welding powder is placed on the starting powder which will be ready for welding work.
The welding powder consists of copper oxide and aluminum which is measure into specific weight in grams for the connections should be made approximatly 97 % of the contents of this cartridge is the weld metal, the remaining part is a starting powder which is tamped into the bottom of the each cartridge.
STEEL DISC
Steel discs are very important. The disc acts timing device to allow the welding powder to heat to proper temperature, the disc away allowing the molten copper to a point where it would weld metal to enter the weld gravity before ignition.
