Re: [MW:36054] Weld overlay on F6 Nm

Preheat substrate  base material to 150-260degC.

Use 309L or 309LMo as barrier layer or buffer layer for 1-2 passes.

Apply E410 for better corrosion resistance.

Perform Tempering on the weld

Thanks & Regards

Yes, you can use multiple PQRs to support a single WPS under AWS as well but it’s handled a bit differently than in ASME Section IX, and you need to be careful about how you justify it.

Dear experts,

For procedure qualification as per ASME SEC IX- "Multiple PQRs may support one WPS",

Likewise can we follow the same practice in AWS also?  Because which is not mentioned directly on the code that we can use multiple PQRs to support one WPS.(And I'm not using prequalified WPS)

Thanks & regards

Prabaharan
