Re: [MW:32724] QW 200.4: Combination of Welding Procedures

Sir, wishing you a very happy new year!!

QW-200.4(b) is an alternative to QW-200.4(a).

Under QW-200.4(a) we can combine the two PQRs, in my below case describe in my earlier email . Writing  one WPS allowing both processes with the following ranges

Base metal: 1.5 to 16 mm

SMAW weld metal: 16 mm maximum

SAW weld metal: 16 mm maximum.

there is no need to use the alternative provisions in QW-200.4(b) to do that. Thus root pass PQR with 13 mm is not required. All I was looking is an interpretation if one js available. 

Thanks for your message.

In 2019, it is clearly mentioned that when combination is made, the process which is going to be used for Root pass, shall have qualified at least 13mm thick.

In 2021, it is not specific about root pass process qualification thickness, but it is clear that u can combined/individual the process in  which each combined or individual might have been qualified at least on 13mm thick. 

If any of process is not qualified on 13mm thick, shall not be combined. any process can be used for root pass with max 2t and another one with maximum base metal thick.

Hi,

Currently one of my clients is having an ambiguity in applying the requirements of ASME Section 09 Clause QW 200.4: Combination of Welding Procedures, Subclause:  a & b requirements. Hence, support is required in finding an interpretation from ASME Section 09. (Interpretation in CS connect is not apparent for this clause)

Background: Two PQRs were qualified separately, PQR A is qualified with SAW process using 8 mm thickness plate and PQR B is qualified with SMAW process using 8 mm thickness plate.

Question: While combining the two PQRs to weld a plate with thickness(es) ranging from 1.5 mm to 16 mm.

Do as per QW 200.4, it is necessary to have the root pass process PQR need to be qualified on a minimum 13 mm thickness plate?

I'm pretty sure it is not required to have a root pass process PQR with minimum 13 mm thickness in the above case. However, it would be helpful if you found any interpretation on this.

Basically 13mm changed from Weld metal thickness to Base Metal thickness and qualified weld metal thickness is 2t.

Just to add,

Process applicable for SMAW,SAW etc..

Only if the maximum BM thickness beyond the qualified range during PQR then qualifying for 13mm separate process is applicable during combination.

[MW:32712] QW 200.4: Combination of Welding Procedures

Hi,

Currently one of my clients is having an ambiguity in applying the requirements of ASME Section 09 Clause QW 200.4: Combination of Welding Procedures, Subclause:  a & b requirements. Hence, support is required in finding an interpretation from ASME Section 09. (Interpretation in CS connect is not apparent for this clause)

Background: Two PQRs were qualified separately, PQR A is qualified with SAW process using 8 mm thickness plate and PQR B is qualified with SMAW process using 8 mm thickness plate.

Question: While combining the two PQRs to weld a plate with thickness(es) ranging from 1.5 mm to 16 mm.

Do as per QW 200.4, it is necessary to have the root pass process PQR need to be qualified on a minimum 13 mm thickness plate?

I'm pretty sure it is not required to have a root pass process PQR with minimum 13 mm thickness in the above case. However, it would be helpful if you found any interpretation on this.

Regards,

Sudhakar K CEng MWeldI,IWE.

There are no any guidelines in Codes for NDT after or before PWHT.

For Gr 91 welding , it is now after PWHT only.

In General  , industry standard is  as below

1. For Alloy steel,  NDT is after PWHT .

2.For Carbon steel , NDT is done before PWHT.

Re: [MW:32705] WPS/PQR software

There are software for making WPS/PQR and developed almost 15 years back like CSPEC, etc..which I have used.

But these are licensed, user friendly and not available as freebies.
