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.
