Exothermic welding is a process that involves heating two or more metals in a mould. This is done to produce a bond that will improve the structural, mechanical, and electrical properties of the joint. This type of welding generally uses graphite moulds to form the joints, as well as electrodes and welding powder. These powders are of the highest quality and are made from copper and aluminium.
Exothermic welding powders are made of copper oxide and aluminium and are packed in plastic cartridges. The weight of each cartridge ranges from 25 to 250 grams. There are metal retaining discs at the bottom of the cartridge, which compact the powder. The powder does not ignite spontaneously, is shock-resistant, and does not cause sparks.
The exothermic welding process is a quick, easy, and efficient way to weld copper. It does not require any outside power. The heat of reaction between the copper oxide and the aluminum powder is transferred to the weld area, causing the metals to fuse together. This method can produce high temperatures of 2400 degrees C.

Exothermic Welding Powder Is A Simple, High-Efficiency, High-Quality Metal Joining Process That Utilizes The Chemical Reaction Heat Of A Metal Compound As A Heat Source, Through Superheated (Reduced) Molten Metal, Directly Or Indirectly Heated, In A Special Graphite Mold A Welded Joint With A Certain Shape And Size In Accordance With Engineering Requirements Is Formed In The Welding Chamber. At Present, Exothermic Welding Has Generally Replaced The Mechanical And Physical Connection Methods Between Metals In The Past. Many International Standards Recommend The Use Of Exothermic Welding Processes In Grounding Systems, Such As IEEE, IEC, NEC, ASME, Etc.
