What information must be marked on each welding wire spool?

Each welding wire spool must be permanently and legibly marked on the outer face of one or both flanges with no less than the following information: Alloy name, specification number, size, quantity or weight, heat number (if applicable), manufacturer’s identification, and EESOH-MIS label.

How must welding rods be packaged and marked?

Welding rods will be suitably packaged to ensure against damage during shipment and be legibly marked to be visible from the outside of each unit package with no less than the following information: specification number, manufacturer’s identification, size/weight, and lot, control, or heat number.

What happens when a new lot of welding wire or rod does not conform to marking requirements?

If new lots of welding wire and rod are received as not conforming to this requirement, then the entire lot must be marked as non-conforming, segregated, and returned to the supplier.

How long can unknown welding material remain in the unknown material area?
