Exothermic welding is a process that bonds conductors to conductor, or conductors to steel surface together, by molecular bonding with no porosity inside weld joint. This results in excellent electrical conductivity, and superior mechanical strength in every environmental condition. The welded joint can be buried directly in soil or concrete, making it ideal for underground Electrical systems in substations and power plants, Cathodic protection for pipelines, Railway systems, Lightning protection systems, Telecommunication networks, and any installation requiring long-term reliability. Unlike mechanical connections, exothermic welds do not loosen over time and provide a service in life itself.
Graphite Mould
Kumwell Graphite Mould, an exothermic welding mould is manufactured from high-quality graphite, accurate production and expert engineering
- Earnest design: Weld capvity, flow path.
- High-quality raw material
- Accurate tolerance
- Deration: at least 50 times in normal usage and storage.
Example Connection Type
Weld Metal Powder
Kumwell Weld Metal Powder is made from high quality material, test and inspection compliance with international standard UL 467 and IEC 62561-1
- Nontoxic and heavy metal.
- Steady burn without pop and fire out.
- No slag and porosity.
- Consistency of color.
- High conductivity
K-MAX (Electronic Ignitor – Ultra Safety)
K-MAX is an innovative system that provides a safer and easier exothermic welding process. It significantly reduces exposure to smoke and flame commonly associated with traditional flint gun ignition. Designed for convenience, K-MAX is especially suitable for confined or hard-to-reach areas, offering remote ignition capability for operator safety. The K-MAX Elitor comes equipped with a 1.80 m cable, providing flexibility and confidence in every welding operation.
Handle Clamp & Support Handle
Kumwell Handle Clamp & Support Handle are used for handling clamping the mould fit to the right position and tightening, without leakage during the Exothermic welding process.
Handle Clamp for Railway
Kumwell Handle Clamp for Railway Applications has only 3 type differences; HCB00, HCC00 and HCD00, which is suit with many different sizes and types of Railway graphite mould.
Necessary Tools
Kumwell Standard Tools are specially designed to support the Exothermic welding process, ensuring efficiency, safety, and reliable performance.
