D1.8 Certifications

Additional Certificates Available Online.

AWS D1.8 mandates a series of tests that must be performed before various filler metals can be used to make Demand Critical welds. While AWS D1.8 permits these tests to be performed by fabricators and erectors, it also allows for manufacturers like Lincoln Electric to conduct such tests. When three different lot test certificates comply, these approved filler metals fulfill the AWS D1.8 lot waiver requirements. Three certificates are available for the following Lincoln Electric electrodes and diameters online. A sample certificate for each qualified product is included on the following pages.

SMAW and GMAW Certificates of Conformance

SMAW electrodes of the classification E7018, E7018-X, E7018-C3L and E8018-C3, as well as solid GMAW electrodes, are exempt from lot and hi/low heat input testing, providing the Certificate of Conformance shows a minimum of 20 ft•lbf at 0°F. See D1.8, clause 6.3.8.
