Do I still need to enter the welder’s ID?
Thread Content
Previously, after pipeline welding was completed, it was necessary to mark the weld site with the welder’s stamp at a distance of about 50 mm from it; it seems that using such stamps is no longer recommended nowadays. Please share your practices.
Our approach is to, after the pipeline welding is completed, mark the welder’s ID, welding date, and weld joint number on one side of the weld joint using an oil-based marker, to facilitate non-destructive testing and inspections by various parties.
Sometimes, welder numbers are marked by region
If the method of using labels combined with line diagrams is employed, those labels will inevitably fade over time. So, in the event of a leak in underground pipelines in the field, how can it be determined which welder is responsible? It’s not possible to dig up all the pipelines just to check the serial numbers of their welds. Are there any specific guidelines regarding the identification of welders?
