Traditionally, aluminothermic welding has been carried out using different compound powder weights. Each one of them comes in different cartridges which account for numerous product references depending on the type of union required. Due to its characteristics, the powder format has some disadvantages which are solved with the tablet format.
The compound in tablet format Apliweld® Secure+ makes possible every kind of union between conductors using exothermic welding with only two references.
One reference, the most usual one, covers 8 traditional references between 32 and 250 grams of compound powder, whereas the second reference, a larger tablet, is only used if the union is made between conductors of section over 150mm².
The fact that the Apliweld® compound does not come in a plastic container ensures a safer product for the environment. The tablet compound does not require individual packaging so they do not generate any extra waste.
The main advantage of the compound in tablet format for storage is that you only need one reference (two at most) to carry out any kind of welding. This means the storage is simplified and the stock variability is reduced.
The exothermic welding Apliweld® Secure+ is sold in cardboard boxes. Each one of them includes 20 tablets.
Tablet charges do not absorb moisture and are not flammable so they do not require special physical or environmental protection for their storage.
An aspect of great interest to develop improvements in the exothermic welding field is the safety and occupational risk prevention.
Aplicaciones Tecnológicas has replaced the flammable ignition powder and flint gun by the non-flammable ignition caps and a remote electronic ignition unit.
The remote electronic ignition system allows the operator to start the welding remotely with the help of a remote control. The remote ignition with Bluetooth maximizes work safety when carrying out exothermic welding.
The “NTP : Safety in aluminothermic copper welding” is a technical note for prevention of the Spanish National Institute for Occupational Safety and Health, which recommends the remote ignition and the use of non-flammable materials to work safely and eliminate the most important occupational risks.
For this reason, Apliweld Secure+ has become a benchmark in safety for any installation which requires exothermic welding, having to comply with the aforementioned document.
Exothermic welding works are often carried out outdoors.
The handling of tablets and starters is much easier than the handling of powder due to their compact design. For example, the possibility of losing material because of spillage of powder is eliminated. Moreover, work in windy days is just as simple as in days with good weather.
In the mould the number of tablets to be used is indicated according to the type of union to be made.
The tablets have a central notch which makes them easier to be split up manually without effort.

Exothermic weld powder is a special type of welding powder that helps create a stronger, more durable weld. This type of welding powder is most commonly used in industrial applications, where it can help to improve the quality of the welds. Exothermic weld powder is made up of a variety of different metals, all of which have been carefully selected for their ability to create a strong bond. When these metals are heated, they create an exothermic reaction, which helps to fuse the metals together. This type of welding powder is often used in conjunction with other welding techniques, such as arc welding or gas welding. It can also be used on its own, though it is not as common. If you are looking for a way to improve the quality of your welds, then you may want to consider using exothermic weld powder.
Exothermic weld powder is a material that releases energy when it is heated. This energy can be used to weld two pieces of metal together. The exothermic weld powder is placed between the two pieces of metal that need to be joined. The welded powder melts and creates a bond between the two pieces of metal.
The exothermic weld powder is made up of several different materials. These materials are chosen for their ability to release energy when they are heated. The most common materials used in exothermic weld powder are aluminum, magnesium, and titanium. These metals have a high melting point and will not burn or vaporize when they are heated.
The exothermic weld powder is placed between the two pieces of metal that need to be joined. The welding process begins when the two pieces of metal are brought into contact with each other. The heat from the contact between the two pieces of metal melts the exothermic weld powder. As the weld powder melts, it creates a bond between the two pieces of metal.
The advantages of using exothermic weld powder include the fact that it can be used to join dissimilar metals together. It also has a very high melting point, so it can be used to join metals that would otherwise be difficult to weld together. Additionally, exothermic weld powder provides a strong bond between the two pieces of metal being joined.
Exothermic weld powder is a specially formulated mixture of metallic powders that, when ignited, produce an exothermic reaction. This reaction releases heat and produces molten metal that can be used to weld two pieces of metal together.
There are three main components to exothermic weld powder: fuel, oxidizer, and binder. The fuel is typically aluminum or magnesium powder, which will ignite and produce an exothermic reaction. The oxidizer is typically potassium perchlorate or sodium chlorate, which provides oxygen for the reaction. The binder is typically a polymer such as polyethylene or polypropylene, which helps to hold the powders together before ignition.
Exothermic weld powder must be carefully mixed in order to achieve the desired reaction. The ratio of fuel to oxidizer is critical, as too much or too little of either can result in an insufficient or explosive reaction. Once mixed, the powder must be compacted into a pellet or tablet form in order to be used in welding.
When ignited, exothermic weld powder produces an intense heat that can reach °C (°F). This heat is used to melt the metals being joined together, creating a strong weld joint. Exothermic welding can be used on most metals, including iron, steel, aluminum, and copper.
When working with exothermic weld powder, there are a few precautions that should be taken in order to ensure safety.
First, always wear protective clothing, including gloves, goggles, and a respirator. Second, never mix exothermic weld powder with any other type of powder or substance.
Third, always work in a well-ventilated area.
Fourth, when igniting the exothermic weld powder, use a long lighter so that you can keep your hands at a safe distance. Finally, always extinguish the exothermic weld powder completely after use.
