Leister Proctors IAGI Certified Welding Technician Program
PLANTSVILLE, CONN.―New England Liner Systems, a Connecticut-based lining installation contractor, recently hosted IAGI’s PE Certified Welding Technician (CWT) program. The CWT program is administered (proctored) by an independent third-party on behalf of IAGI; in this case, Steve Hobbs, Leister Technologies’ manager of Geo-systems for North America, served as the proctor.
“It’s a very thorough and comprehensive exam,” said Mr. Hobbs. “If a field technician can pass the CWT test, they’re going to be an asset in the field.”
To qualify to take the CWT exam, each candidate must provide a resume of experience demonstrating a minimum of 1,000,000 square feet of installation experience, from at least five different job sites. Nine members of New England Liner Systems’ field installation crew participated and now are eagerly awaiting their results.
According to IAGI, the importance of the program is to “recognize the knowledge, experience and skill of welders in high density (HDPE) and linear low density polyethylene (LLDPE) geomembrane welding.” The exam provides candidates with two hours to complete the written portion of the exam, when booklets are collected and sent to IAGI headquarters for review.
During the practical session, an additional two hours are allotted to complete each hands-on skill. The hands-on session consists of creating three wedge welds and two extrusion welds on a variety of membrane types and thicknesses―both HDPE and LLDPE―as well as a variety of smooth and textured materials of different thickness. Machine set-up and selection of weld parameters are the responsibility of the candidate.
Candidates submit samples of their best completed welds, and each weld is sent to an independent third-party laboratory for testing. Those with passing scores will be awarded the Certified Welding Technician (CWT) certificate. The CWT credential is a requirement on certain jobsites.
