Dear all, I have a question regarding P45 materials welding. I have a qualified WPS that made with UNS N08020 (SB729) PQR. And I want to use this procedure on Alloy 20 which is UNS N08825 numbered material.

According to ASME you can weld the materials that are in the same P number and G number. And both of those material is P45 (no group) material, I dont see any problem with it but I heard something else, could you check this too.

Pratheesh,

Chemical composition should meet the requirements of EN 10219 only. There is no specifc DNV chemistry requirement other than meeting the EN standard . Section 3.1.2 of DNV 2.7-1. If we require additional elements then we should specify at the time of the order or it will be standard elements.

The material should meet the requirments of EN 10219 with regard to NDE  and marking as per EN 10219. See below

Impact as per DNV Figure 3.1 

9.4.2 Electric welded sections 

The weld seam of electric welded hollow sections shall be tested in accordance with one of the following European 

Standards. The standard to be applied is at the discretion of the manufacturer. 

a) EN 10246-3 to acceptance level E4, with the exception that the rotating tube/pancake coil technique shall not 

be permitted; 

b) EN 10246-5 to acceptance level F5; 

c) EN 10246-8 to acceptance level U5. 

9.4.3 Submerged arc welded sections 

The weld seam of submerged arc welded hollow sections shall be tested either in accordance with EN 10246-9 to 

acceptance level U4 or by radiography in accordance with EN 10246-10 with an image quality class R2. 

Butt welds, used to join lengths of strip/plate together in the spiral submerged arc weld process, shall be permitted, 

provided that the butt weld is tested to the same type of procedure and meets the same acceptance level as the 

main weld seam

10 Marking 

10.1 Except as provided for in 10.2 for hollow sections which are bundled, each hollow 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-S275J0H; 

 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).
