Weldability of EN 10219 S355J0H Pipe

This European standard only allows for the use of weldable steel. EN 1011-1 and EN 1011-2 specify the critical parameters for the welding of the products covered by this European standard.

While welding these materials, the primary worry is the development of cold cracking in the welded zone as the product’s thickness, strength level, and CEV grows. Cold cracking happens for a variety of reasons:

  • Enhanced diffusible hydrogen concentrations in the weld metal;
  • Brittle structure in the heat-affected zone;
  • High tensile stress concentrations in the welded joint

Marking of EN10219 S355J0H

Except as provided for in EN10219 10.2 for hollow sections which are bundled, each S355J0H section shall be marked by suitable and durable methods such as painting, stamping, adhesive labels, or attached tags with the following:

— the steel designation e.g., EN 10219-S355JOH;

— the manufacturer’s name or trademark;

— in the case of specific inspection: an identification number, e.g., order number, which permits the correlation of the product or delivery unit to the related document;

— the mark of the external inspection representative (where applicable).

 

When the items are provided bundled, the EN10219 10.1 marking must be on a label that is firmly affixed to the bundle.
