In , nVent ERICO completed the development of and patented the nVent ERICO Cadweld Exothermically Welded Connection. nVent ERICO Cadweld. Cadweld molds position and prep materials that need to be welded. Ground your equipment with a welding mold from GME Supply. Give us a call or live chat us. Because the CADWELD® PLUS process uses a high temperature reaction of powdered Copper oxide and Aluminium the mold needs to withstand these high .

Uses lightweight, inexpensive equipment. Requires no external source of power or heat. Requires no special skills. Weld metal a mixture of copper oxide and aluminum is dumped into the top of the mold. The mold is covered and the weld metal ignited.
The exothermic reaction produces molten copper, which produces a permanent, high conductivity connection. Bonds with terminals formed on the ends are often used for bonding pipe joints and fittings. The formed terminal allows a smaller weld metal size to be used. Formed Terminal Bonds may be made in the field using sleeves one per conductor end and forming them in a hammer die. Insulated formed terminal bonds with insulated pigtails are used to bond across the joint and to bond both the middle ring and follower ring of “Dresser Type” couplings.
In colder climates, water distribution pipes occasionally freeze in the winter.
To thaw the ice, a high current for example, from a welding machine is applied to heat the pipe and thaw the ice. To accomplish this, each pipe joint must be cadwled bonded to control the electrical path and to prevent burning the pipe gaskets. The bonding straps have been tested at over amperes.
Molds – Cadweld
The straps may also be used to provide continuity for cathodic protection or grounding systems. The 5-hole model is used on “Dresser Type” pipe couplings with two welds to the pipe and three to the coupling, made through the holes.
A 2-hole model is used across standard mechanical joints or across “Dresser Type” joints when the coupling does not have to be bonded. However, some reports from the field suggest that all ductile iron is not the same. Cadwele some cases, the material for steel will not work.
In such cases, the molds and weld material for cast iron do work. Please contact Farwest Corrosion Control Company for sizes and ordering information. Type CATA connections are available for any combination of run and tap conductor sizes.
If mold only less frame is required, order Welder Part No. Each tube contains the starting powder fadweld the bottom of the plastic tube, with the weld metal on top.
These containers are packaged, with metal disks, in polyethylene boxes. The welding metal cannot ignite spontaneously. They can be handled and stored without danger and can be shipped with no special packaging or marking. Shim Stock is useful to adapt the conductor when a variety of sizes exist and only a few connections of each one are required.
Small conductors may be built up to fit the opening of larger size welders using either adapter sleeves or shim stock. Self-igniting propane torch head.
Squeeze the control knob for an instant flame. Release, and it’s out. And the burn tip remains cool during normal use. Operates on its side or upside down. Can withstand Molsd winds without flareout. Fits all cwdweld 14 and 16 oz propane lighters. Extension Flint Lighter, 30″ long. Replacement Flint Igniter Only. Fits all CAA price welders and pipes up to 6 inches. Once attached to the mold handle, the BN2 securely holds the mold to large flat or slightly curved horizontal steel surfaces during the connection process.
Powerful welding magnet 50 lb rating securely positions mold during connection process. Helps with mold stability to reduce the chance of weld metal leakage. BN2 attached to mold frame on steel pipe during connection process. S and Canada only Call our National Headquarters You have no items in your shopping caeweld. Home Products Marine Caadweld.

Cable Connections Uses lightweight, inexpensive equipment. Therefore, no galvanic corrosion can occur at the interface. With mechanical connections, surface contacts are present, and can corrode, resulting in an ineffective current path. CADWELD connections for cathodic protection use a special alloy to provide minimum heat effect on the steel, especially important on thin wall, high stress pipes.
CADWELD connections are also used for header cable taps, conductor splices and terminations, and ground rod connections. Has current carrying capacity equal to that of the conductor. Is permanent – cannot loosen or corrode to cause a high resistance connection. Can be easily checked for quality. A test weld should be made on a section of the pipe being used to determine possibility of detrimental metallurgical effects.
Field Made Bonds Formed Terminal Bonds may be made in the field using sleeves one per conductor end and forming them in a hammer die. In both, under Corrosion Control, the code allows the attachment of electrical leads using exothermic welding but limits the size of the weld metal used to: CA15 for steel pipe. When larger sized conductors must be attached to pressure piping systems covered by these codes, several alternative solutions are available: The mokds model is used for “Dresser Type” couplings and the 2-hole model for standard joints.
The strands of a larger 7 strand conductor can be spread and each strand welded separately as noted in the following table: F alloy is used for all connections of cable to cable and cable to steel or stainless steel pipe. The F weld metal containers have green caps. XF alloy is used for all connections to cast iron. XF weld metal containers have orange caps. Size Packed per Box Std. Send Us Your Feedback.
