INTERNATIONAL ASSOCIATION OF GEOSYNTHETIC INSTALLERS
Certified Welding Technician
Welder's Certification Program
Benefit to Engineers
Engineers
benefit from IAGI's Certified
Welding Technicians (CWT) program because it verifies
that the welders on their job have experience
in welding. Additionally, they can
specify that the polyethylene geomembrane welders are certified for the
type of welding they will perform. The CWT program
certifies welders for both extrusion and
fusion welding methods.
Purpose
IAGI developed a welder's
certification program so installers could
define standards of proficiency, recognize
the knowledge, experience and skills
of installers, and reward those who qualify with industry recognition.
Certification Includes:
·
Proctored
written examination
• Hands-on welding
demonstration with third party laboratory pass/fail evaluation
• Testing for polyethylene & reinforced
geomembranes; wedge & extrusion welding

Specification
To make it easier
for engineers and designers to include
this information in job
specifications, we have created
the following wording for engineers to use:
"The Geomembrane Installer shall
designate a Master Seamer. The Master Seamer shall
be present during all seaming operations and shall
have a minimum of
(your company's minimum requirement)
square feet (your company's minimum requirement) square meters of
field seaming experience and hold an International Association of Geosynthetic Installers (IAGI) Certified Welding Technician
(CWT) certification in both extrusion
welding and fusion welding."
