Puneet,
Acceptance criteria for UT is as laid down between the purchaser and supplier, Usually a purchaser's design engineer looks in to it. A UT proc is avlbl in ASTM E 388 for heavy forgings.. But I doubt of acc criteria. It is application specific.

Dear Kevin, AWS -CWI certificate is valuable and really counts for overseas job as a welding Inspector in Middle east. In India its an advantage but as you know its not mandatory in India. As you are working with ABS, after passing AWS -CWI they can send you for offshore welding inspection jobs. In gulf, no doubt its valuable and the salary ranging from - 60K - 150K INR PM depending on your experience. After all getting yourself equipped with certifications and qualifications never be on loosing side. So go for it! best Luck.

Hi, Regarding the foot note, Metallurgically, 0.01% of C equivalent to 0.06 % Mn ; that is why in all specification you could find this general comment. So, if Mn increases to 1.36 % , there will be a definite reduction in Carbon percentage. For, CE = 0.47 , preheat 95 deg Cel is enough to get the good results, As CE increases your weldability decreases, but you cannot directly relate the Mn to weldability. Thanks & Regards, K.Babu

Dear Sir
Thanks for your valuable advice. However we have landed up in one more hurdle in same job discussed below.
The SA105 forging is having Mn content on higher side i.e 1.19%.
as against specification of 1.05% max.
There is a footnote stating that as per --- Mn=1.36% max is also allowed.
The Carbon content is 0.22%.
Due to high Mn content the CE is 0.47.
Now with such high CE should we preheat the joint to the same temp. of 75DegreesC adviced by you ??
Will this high CE of 0.47 and high Mn content affect the weldability of CS#SS joint?
Also as per ASME Sec VIII Div 1, Non-mandatory appendix R (R1 & R7), preheating is not required for this P1#P8 joint.
But client is adamant and says that Non-Mandatory appendix should never be followed. Is this approach true.
Client is telling that only Mandatory appendix should be followed !!
Please advice !

Test should be 100% Body and seat but you can witness the test randomly it mean number of valve wise for example out of 100 valve you can witness the test 15 valves Body as well as Seat test.

WQT aims at judging welder's ability to deposit sound weld using a given electrode/filler and the qualified process per the WPS. The material on which to deposit does not matter.

According to QW-423.1 & QW-433, you can qualify the welder for P No. 1 material using F No.43 consumable.

Definitely NOT POSSIBLE, Tamil! You should use the same material (P45) only for welder qualification
also. The range can be applied from P41 through P49 (not P1) with F Number
fixed Thanks

Thank for your promptly respone and highly appreciated. Unfortunately i don't have B31 code case (181 and 2235). Any one can share with me?

refer code case 181
"ASME B31 committee has developed B31 Case 181 to permit the use of
UT, particularly TOFD in lieu of RT for B31.3 applications. ASME B31
case 181 was apparently taken from ASME Code Case 2235, which
addresses the UT examination in lieu of RT for vessels and not piping.
The major difference from what I can see between B31 case 181 and ASME
Code Case 2235 is the minimum wall thickness requirements and maybe
the acceptance criteria.
As we all know ASME B&PV codes looks at flaws by aspect ratios. a/l or
vertical height divided by length. That gives you the aspect ratio
which is then used to determine the maximum flaw size permitted. You
can actually accept cracks per the ASME B&PV code as long as they are
within the acceptable limits, but not with ASME B31.3.
After looking at the acceptance criteria for B31 Case 181, I see that
they are using the same philosophy.
Where ASME B31.3, Table 341.3.2 does not allow any cracks for RT and
in most cases no IF. Why would cracks be permitted with UT and not RT?
I believe the B31 Case 181 was taken from ASME Code Case 2235 and the
reference to cracks was inadvertently missed. When using TOFD you can
differentiate between linear indications and cracks. Does anyone know
of any reference by ASME B31 committee regarding this issue?"

Subject: [MW:2255] Partial Penetration Joints Hi friends
I need some advice from seniors.
I need to qualify a procedure for a partial penetration joint as per ASME SecIX.
The joint thickness is 56mm, single bevel butt joint. The depth of bevel is only 16mm and thus it is a partial penetration joint.
Now to qualify the WPS/PQR, should i select a 38mm or more thick plate as per QW202.2(b) ??
The statements in QW202.2 are a bit confusing!

Dear Sir Thanks for your valuable advice. However we have landed up in one more hurdle in same job discussed below. The SA105 forging is having Mn content on higher side i.e 1.19%. as against specification of 1.05% max. There is a footnote stating that as per --- Mn=1.36% max is also allowed. The Carbon content is 0.22%. Due to high Mn content the CE is 0.47. Now with such high CE should we preheat the joint to the same temp. of 75DegreesC adviced by you ?? Will this high CE of 0.47 and high Mn content affect the weldability of CS#SS joint? Also as per ASME Sec VIII Div 1, Non-mandatory appendix R (R1 & R7), preheating is not required for this P1#P8 joint. But client is adamant and says that Non-Mandatory appendix should never be followed. Is this approach true. Client is telling that only Mandatory appendix should be followed !! Please advice ! Regards Prem Nautiyal Godrej, Mumbai.
