Codes such as AWS D1.1 & ASME IX require welders to weld at least one weld every 6 months in a process they are qualified to, in order to maintain their welder qualifications for that process.
In WeldTrace, each welder’s log will be updated automatically on a continuous basis from records of welds performed by a welder within a project (PLUS and PRO plans only).
If a welder is qualified to multiple processes, the continuity update will be applied to the specific process of relevant WPQs. If one of the processes in a multi-process WPQ expires (i.e. no continuity update is applied for over six months), that particular WPQ will expire and it cannot be used in a project.
