In what circumstance can a CWI whose certification has expired accept D1.1 work?

Accepting D1.1 work with a current visual acuity test is valid because visual acuity is a critical competence for a Certified Welding Inspector (CWI). It ensures that the inspector can accurately evaluate welds and other components, a fundamental requirement in maintaining the quality and integrity of welding work. As such, having a current visual acuity test signifies that the inspector can still effectively perform inspections despite their certification having lapsed. This provision allows for a practical compromise in ensuring that quality standards are upheld while addressing the inspector’s certification status.

In contrast, options like waivers from AWS or letters of recommendation do not have a recognized basis in the D1.1 code for reinstating a CWI's ability to accept work, nor do they address the essential skills necessary for performing inspections. Additionally, re-certification within the last year does not apply to a CWI with an expired certification; re-certification must occur before the expiration to ensure continual compliance with industry standards.
