Re: [MW:33375] WELDER QUALIFICATION

Dear Mr. Saleem

Please note that as far the essential variables of the welder are within the ranges of the second WPS, the welder is qualified to weld using the second or any number of WPS.

Please note for welder qualification actual essential variable and the qualified essential variables alone are mandatory in the Report and the WPS used for welding coupon is non mandatory as per my knowledge.

Regards
Sham Shahabuddin

Re: [MW:33370] USER's definition in API codes

Dear Krishna, 

In your case you must use epoxy grouts in all cases, 
And the Client/User/Owner can say whether the use epoxy grouts for all machinery can have any other alternative method or not. 
EPC dont have the right to override this. You may also raise a TQ to get a waiver or any alternative ways for this from client.

regards

Re: [MW:33365] Clarification on Case hardening process

Material is not suitable for surface hardening as it is a ordinary construction steel.

Op 5 aug. 2022 om 08:07 heeft SURESH <qms.pjgpl@gmail.com> het volgende geschreven:

Dear Experts
Please need some suggestions on the below query.

Case Hardening process to achieve 60±2 HRC, Hardness Depth:1.5mm

Material: EN 10025-2 Grade S355J2/ 1.0577 DIN

We have tried carburizing and Nitriding methods to achieve this, but we have failed to achieve 60HRC. Instead, we achieved only 41HRC at the top surface and 23HRC on the 1.5mm surface during the examining in hardness survey.

Can anyone help me out with how to achieve this hardness?

Can anyone explain about the Acceptance criteria of Hardness for the weld metal. If my PQR is as per ASME SEC IX and if the hardness test is done, on what basis the test results are acceptable. 

Also please explain the same condition if we are qualifying dissimilar metals
