How to Use Exothermic Welding Powder

Update:03 Nov,2022

The first step is to prepare the welding chamber. It should be clean and free from debris. Then place two conductors in the Weld cavity. If the tap hole is blocked, use a metallic disc to block it. Next, pour the Exothermic Welding Powder Material. Then, sprinkle starting powder on top of the mould. This process will take approximately 3-4 seconds. Once complete, the resistance will decrease due to the fusion of the two metals.

The exothermic welding powder process requires various tools, including a handle clamp, mould, and welding powder. It is used to join two metals, such as copper and steel. Copper provides better electrical conductivity and is resistant to degradation. Therefore, the connection will be long lasting and low-resistance.

Exothermic welding can be used for different applications. For example, it can be used to connect steel reinforcing bars. The metals are heated using a thermite exothermic reaction. The result is an irreversible bond between the two metals. Exothermic welding is very efficient, and can be used on a variety of materials. In addition to copper, it is possible to use aluminium in combination with iron oxide. Thermite can be made from copper or chromium.

Another use for exothermic welding is in the electrical field. It is used to tie copper conductors together and creates electrical joints with minimum resistance and stability. Exothermic welding is also a great way to improve the reliability of ground contact joints. Weak ground contact joints can lead to high currents, corrosion, and other safety risks.

Exothermic Welding Mould

Exothermic Soldering 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.
