Re: [MW:30285] Re: Hard Facing Overlay Test Required

What you have welded is not a Corrosion Resistance overlap, it is a Hardsurfacing overlap, in which no PRN required. Only Hardness value is required. Thanks

HI,

        Actually when i worked in Aramco project,They recommended min PREN value for overlay portion as per SAES.

common formula for PREN value=%cr+3.3 X Mo%+16 x N%

Dear Mr.Ragul

Thanks for the response.

How to ensure that PREN meeting the chemical analysis. I have tested Welding of ERCoCr-A PTAW powder with ASTM A36, SS316L, F11,F22,F91 MATERIALS.

 Can you provide which standard or value to refer for acceptance and how to check the same?

Dear Experts,

Please give me the guide for Hard facing Overlay:
We did a) Visual Examination, b) LPT, c) Hardness Test, d) Macro, e)
Weld Metal chemical analysis.
Is there any other mechanical or other test required for HFO like
Tensile or Bend test required?
Please guide me with ASME Sec IX 2010.
