Some advantages of Exothermic Welding Powder- Xinchang TuAn Machinery Co., Ltd.

Exothermic welding powder is a highly effective and cost efficient method of making electrical connections mainly between copper to copper and copper to steel. It is a simple self-contained system that uses the high temperature reaction of powdered copper oxide and aluminium within a mould to form permanent electrical connections with no outside source of heat or power required.

The process is very versatile and can be used to make all kinds of connections requiring no external heat or current. In addition to its flexibility, this process is also extremely portable and has no maintenance issues - it can be submerged in water without losing the integrity of the connection or causing hydrogen pickup.

It is also a great choice for joining wires that are in electronics. This process does not damage the electronics and can even join wires that have very low resistance and conductivity levels.

A molten copper alloy is formed during the reaction which flows into the weld cavity, partially melting the conductors to create a permanent joint. Once the molten alloy cools, it hardens into a solid copper fusion weld with excellent mechanical and electrical integrity.

The weld is insulated to protect the conductors from any accidental contact with any other part of the circuit. It is a completely safe, clean and easy to use connection that is superior in performance to any mechanical or pressure type surface-to-surface connection.

This process is particularly useful in grounding circuits, where the ability of a connection to withstand repeated fault currents and not loosen or increase in resistance over the lifetime of a grounding circuit is important. A successful earthing circuit relies on the integrity of its connections and only exothermic welding provides the superior quality, conductive, permanent and long-lasting earthing connections needed for a reliable grounding network.

These connections are tolerant to repeated fault currents and demonstrate excellent corrosion resistance, making them ideal for all sorts of applications including buried ground circuits in substations, power plants, railways, for cathodic protection and lightning protection. The exothermic weld is a superior choice for grounding connections and has been recommended by IEC and IEEE for the highest standards of safety, reliability and longevity.

Its superior performance makes it the preferred choice for a wide variety of applications, from power transmission to agrichemicals. The exothermic weld is also a very efficient method for joining large cables and other components that can be difficult to weld using traditional methods, such as arc welding or brazing.

A complete exothermic welding system consists of a mould, refractory sealant to close the seams in the mold, exothermic welding powder, an oxidizing agent, preheating gas torch and tanks, clamps or holders, separator and an ignition source. The equipment is lightweight and portable, ideal for field use.

Exothermic Welding Powder

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.
