Overlay WPS?

Overlay WPS?

Overlay WPS?

(OP)
Can I develop an overlay WPS using QW-451.1?
For instance it would be a GMAW P1 to P1 or P8 to P8.
Is this possible without actually welding up a groove?

RE: Overlay WPS?

Refer to QW-453 for overlay qualification.

RE: Overlay WPS?

QW -453 is applicable.

We are following the same.  

RE: Overlay WPS?

By 255.1:
- QW 403.22 point out QW-453.
- QW 403.20 point out that each P number grouping or combination    must be qualified separetaly: P1-P8, P1-P1 or P8-P8.
- QW-216 point out that test coupon and testing of hardfacing or corrosion are quiet different that groove welds.  

RE: Overlay WPS?

(OP)
Are you guys following QW-453 Corrosion-Resistant Overlay or Hard-Facing Overlay?

 

RE: Overlay WPS?

m3brunof,
QW-453 has the provisions and qualificatin for both. For corrosion resistant overlay applications, follow the provision for such therein.

To further answer your question 1.
No. P1 to P1 and P8 to P8 qualifications do not qualify a corrosion resistant overlay.

To further answer your question 2.
Yes, per QW-453.  

RE: Overlay WPS?

"Are you guys following QW-453 Corrosion-Resistant Overlay or Hard-Facing Overlay?"
you are the only one to decide which one apply to your WPS
