Beginning with the September 2014 school, the length of the CPWI+ class will be four and ½ days. Classroom presentations will be held on Monday, Tuesday and Wednesday. On Thursday, the entire day will be devoted to the “Hands-On” Portion of the school. We have learned from previous attendees that they enjoyed actually using the inspection instruments, the welding booths with the different processes and inspecting actual welds from 4” though 18” with different defects.

Learning to measure the actual pipe diameters with a “PI” tape, measuring for pipe magnetism, measuring miter joints, measuring wall thickness with a UT gage, measuring for dents and Hi-Lo among other inspection tasks take a little longer than we originally expected. We will be adding more inspection tasks the inspector may encounter in the field as well.

The cost of the four and ½ day program including the test on Friday will be $1800.00. Your consideration of our new and improved program is very much appreciated.

Since 1977 the national Welding Inspection School (NWIS) has served the Oil and Gas industry by conducting training programs to more than 20,000 attendees representing most of the major companies.

The welding inspection course for "Pipeline Construction and In-Service welding" leads to a Certified Pipeline Welding Inspector's Certificate (CPWI).

Our schools are for inspectors, welders, engineers, superintendents, managers and others involved in the construction of pipelines and plants.

Your consideration of our training programs is very much appreciated. Each class provides a certification in the respective subject.  As we have done in the past, classes can be tailored to your company needs.
