Famous experts do the exothermic type of welding in the Philippines and their prices for welding powder and aluminum welding powder and other equipment are very reasonable. Exothermic welding is a melting process used to create a molecular bond between two pieces of metal placed in a mold without any external heat source. And it does not require an external source of heat or energy. Exothermic welding is most commonly used to permanently join copper conductors or copper tape and copper strips. This is the only acceptable way to connect copper to copper wire. Lightning and grounding systems require connections that maintain a higher current carrying capacity than the conductors used in the system. The exothermic welding process in the Philippines is a method of electrically joining copper to copper or steel without requiring an external source of heat or power.
Welding
The special welding material like welding stainless steel is placed in a mold resistant to high temperatures and ignited. In the process of ignition of the particles, an extremely high temperature and molten metal (exothermic reaction) up to 2000 °C are released to form molten metal slag. This liquid copper metal flows into the weld cavity, filling all available space and completing the weld. The weld is then allowed to cool and solidify before being removed from the mold. After a little brushing, the mold is ready for the next weld. This whole process takes only a few seconds. Exothermic welds form a permanent bond that outperforms any known mechanical or surface-to-surface pressurized contact. In the Philippines, exothermic welding is required when there is a faulty connection between two conductors, which is a common cause of electrical faults.
A correct connection must have the following characteristics:
- Maintenance of electrical continuity and reliability of contacts.
- The ability to withstand overload conditions without melting, igniting, or failing.
- Long service life. Above or below ground, will not corrode, corrode or decompose over time.
- Below are the main characteristics of exothermic welds:
- Molecular bonds of copper scrap and other metals can be formed
- The current carrying capacity is equal to or greater than the conductor.
- does not deteriorate with age
- fails repeatedly
- can be visually checked
- Requires no special skills or manpower
Exothermic welding in Philippine
Exothermic welding, also known as exothermic welding, thermite welding (TW), and thermite welding, is a welding process that uses molten metal to permanently join conductors. This process uses the exothermic reaction of the thermite structure to heat the raw metal and does not require an external source of heat or power. The chemical reaction that releases heat is an aluminothermic reaction between aluminum powder and metal oxide. The exothermic weld has high mechanical strength compared to other forms of welding and excellent corrosion resistance. It is very stable even under repeated short-circuit impulses and does not suffer from increased electrical resistance during the entire lifetime of the installation. However, this process is costly compared to other welding processes, requires a stock of interchangeable molds, suffers from a lack of repeatability, and can be difficult due to wet conditions or inclement weather. Features of exothermic welding: 
- It has better electrical conductivity than the conductors themselves.
- It does not oxidize or decompose over time and is also resistant to galvanic coupling.
- It is able to withstand repeated electrical discharges.
- It never increases its resistance.
- It has higher mechanical strength and crushes resistance than stairs.
- It provides the strong weld and low-resistance connection needed for long-lasting and reliable grounding results.
- This guarantees the most common connections not only between copper cables but also for welded strips and metal parts made of brass, stainless steel sheets, and copper-plated steel earth electrodes.
Amiable is a leading manufacturer and supplier of exothermic welding equipment in the Philippines. Exothermic welding is also marketed under various brand names such as Auraweld, Cadweld, Eriko, Axoweld, Kumwell, Farseweld, Thermoweld, and Aura Weld. AURA WELD is one of the largest manufacturers of exothermic welding fluxes and exothermic welding graphite molds in the Philippines and abroad. Exothermic welding is most often used for the permanent connection of copper conductors. Products are tested and approved by the CPRI government agency. They are also CE and RoHS certified, as well as ISO 9001:2008 certified, a citizen-verified company. 
Exothermic welding powder
In the Exothermic type of welding, we must use the proper powder such as gilsonite powder in order to have the right welding process. Exothermic welding is a procedure that can be used to create high-quality electrical connections between conductors made of copper, copper alloys, or steel. It is a process that is self-sufficient. The procedure entails making use of a graphite mold, which enables the molten metal that is contained within the mold to make contact with the conductors that are there, so welding them in an irreversible manner. The weight of the exothermic metal powder cartridges is adjusted according to the type of weld that will be performed. The cartridges include two different types of powder: - The metal powder can be found under the colored cover. It is a combination of copper and aluminum oxide, and it is used as a raw material to fuse with the conductors that are to be welded. - The ignition powder: It is utilized to start the fusion process when lighting the exothermic welding process. It may be found under the black cover. 
The references of the powder cartridges that need to be used vary depending on the kind of welding that needs to be done and the kind of conductor that needs to be welded. Before pouring the powder into the crucible, the obturation disc, which is also contained in the powder box, is positioned at the bottom of the crucible. The Exothermic Weld Powder is the weld metal that offers the highest level of dependability and performance consistency. After receiving final approval, weld metal is given a special packaging consisting of moisture-resistant plastic tubes sealed with specialized closures. The starting powder is compressed at the bottom of each cartridge with the weld metal on top. The starting powder is released by forcefully tapping the base of the cartridge. Exothermic welding powders are a high-quality blend of aluminum sheet and copper oxide.
