How to CAD Weld on Ductile Iron Pipe

By Jerry Regula, ENV SP, NACE CT 02/18/2021 In Installation Technical

Thermite welding, often referred to as CAD welding, on Ductile iron pipe (DI pipe) and products is a common practice in our industry today. This welding technique of using heat from an exothermic reaction to produce coalescence between two metals is most often used to bond the Ductile iron joints for cathodic protection or for the opportunity to add a cathodic protection system at a later date. In this Iron Strong Blog, we will discuss when, why, and how to properly CAD weld on DI pipe.
