Introduction/Table of ContentsThe CADWELD ProcessCADWELD connections are the accepted method ofattaching Cathodic Protection leads to pipes (steel or cast iron), tanks and structures.CADWELD connections weld the conductors and the structure to be protected so no galvanic corrosion can occur at the interface. The CADWELD process isspecifically formulated to provide minimum heat effect on steel, which is especially important on thin-wall, high-stress pipes.CADWELD connections are also used for header cabletaps, conductor splices and terminations, and ground rodconnections.ERICO®FactsA CADWELD Connection . . .• Has current carrying capacity equal to that of the conductor.• Is permanent with a low resistance connection that cannot loosen or corrode.• Uses lightweight, inexpensive equipment.• Requires no external source of power or heat.• Requires no special skills.• Can be easily checked for quality.ERICO is the pioneer of the CADWELD ExothermicWelding Process for permanent Cathodic Protectionconnections. Specifying the CADWELD Process in your construction plans will dramatically extend thelifespan of infrastructure systems.CADWELD connections are made with a semi-permanentgraphite mold, which holds the conductors to be welded.Weld metal (a mixture of copper oxide and aluminum) isdumped into the top of the mold. The mold is coveredand the weld metal ignited. The exothermic reaction produces molten copper, which results in a permanent,high conductivity connection.TABLE OF CONTENTSINTRODUCTIONConnections to Steel PageCAHA Type 1CAHC Type 2CAVS Type 3Connections to Cast IronCAHB Type 4CAHE Type 4CAVH Type 4Connections to Ground RodType CAGR 5Type CAGT 5Connections of Cable to CableType CAPC 6Type CASS 6Type CATA 7Connections of Cable to LugType CALA 7BondsPlain Strap Bonds 8Punched Strap Bonds 9Formed Terminal - Factory & Field Made 10Formed Terminal - with Pigtail 11Welders and Molds 12Weld Metal 12Tools and Materials 13 - 15Technical InformationPIPING CODE 16PIPE WALL THICKNESS 17Ductile Iron 17Cross Reference 18E394CT09NAEN:LT0398  3/5/09  4:22 PM  Page II
