Welders and brazers are responsible for performing manual continuity or submitting verification of welder and/or brazer continuity by their employer for welding and brazing performed on the job.  Written verification of welder and/or brazer continuity by the employer must be submitted using approved United Association continuity forms and can be returned by email to 

If you are working and have used your welder or brazer certification on the job prior to the date your certification expired, the date you last welded or brazed on the job must be used to submit verification of continuity by the employer.  Welder and/or brazer continuity forms may be accepted after the date of expiration of certification if the form has been filled out correctly by the company representative responsible for being aware that the welder/brazer performed the welding/brazing process is verified. Once a welder or brazer obtains verification of continuity from the employer it is the responsibility of the welder and/or brazer to submit verification of their continuity to maintain current welder/brazer certifications.
