ERICO CADWELD Exothermic Connections

Founded in 1903 as the Electric Railway Improvement Company, ERICO originally specialized in arc-welded rail bonding for the railway and mining industries. While the connections were a significant advancement, the heavy equipment required to complete the welding was a drawback. In 1939, ERICO completed the development of and patented the ERICO CADWELD Exothermically Welded Connection.

ERICO CADWELD Exothermically Welded Connections are specified by engineers and consultants for many industries and installed by contractors and site owners large and small all over the world. With Over 100,000,000 field-proven connections installed around the globe by our very satisfied customers, the “ERICO CADWELD” name has become synonymous with “Exothermic Welding” from the classroom to the job site.

ERICO CADWELD continues to maintain a reputation for electrically superior connections that will never loosen, break, or corrode in most environments.
