NBT47018 Technical Specifications for Ordering Welding Materials for Pressure Equipment – Transition Period

2017-10-02View Original

Thread Content

The transition period specified in the standard NBT 47018-2017 for the technical requirements regarding welding materials has expired. We are boiler manufacturers, and we still have a considerable stock of welding rods and wires that comply with the old 2011 standards. Can these still be used?

Our company is still using it, and we want to know if it can be used again. Or it is necessary to undergo retesting for the additional inspection items required by the new standards before it can be used.
