The JAM WELD Exothermic Welding System provides the ultimate in permanent molecular bonding. The process of exothermic welding, in which no outside source of heat or power is required, is the universally preferred method of making electrical connections of copper-to-copper or copper to steel. Lightning protection and grounding systems require connections that maintain current carrying capacity exceeding that of the conductors used in the system.cadweld connections provide higher fusing capacity than the conductors to which they are bonded. System resistance, impedance, and ampacity relate directly to functionality, safety, and regulatory compliance. JAM WELD meets these challenges and delivers assurance.
Exothermic welding, also known as exothermic bonding, thermite welding (TW), and thermit welding, is a welding process that employs molten metal to permanently join the conductors. The process employs an exothermic reaction of a thermite composition to heat the metal, and requires no external source of heat or current. The chemical reaction that produces the heat is an aluminothermic reaction between aluminium powder and a metal oxide.
