We also recently developed our own exothermic welding system which is available under the brand name of DEM- WELD. Exothermic welding, also known as aluminothermic welding is the process of welding copper on copper, steel on steel, and copper on steel in the absence of an external system providing electrical or other types of power.
The process employs an exothermic reaction of a thermite composition to heat the metal, and requires no external source of heat or current. An exothermic weld has higher mechanical strength than other forms of weld, and excellent corrosion resistance. We use and supply numerous products, accessories, and consumables from the well-known manu- facturers for an exothermic application.
