[MW:28154] dimension for fillet weld

what should be leg length and throat if thickness is given in drawing only ?
how to decide it should be fillet of equal leg length or unequal leg length?
if the T joint ( fillet ) plates thickness are same or different than how do decide throat and leg size without help of drawing ?
please reply on the basis of asme sec 9 only.

[MW:28154] Re: Nitrogen measurement by PMI

hiii

 In PMI test by using x-ray fluorescence machine , it is very difficulty to get level of nitrogen ,carbon ,sulfer etc.I think you can find out this element by using optical emission spectograph machine.

Re: [MW:28154] WELD PLAN REQUIREMENT

Hi

 

Each organization will have their own format based on their own quality requirements.

 

Some may call weld register, weld table, weld descriptions, weld summary plan etc. etc..

 

The points is wherever welding is involved, it should be indicated & supported with qualified WPS/PQR as minimum, NDT requirements / Welder identifications may be added if required.

 

All Pressure parts and Non Pressure parts / attachments, including repairs, buttering, Fillets, dissimilar weld etc.…shall be included in your weld plan.

 

You may check with your quality team / procedure of your organization and previous project reference if any, how the weld plan is finally approved ! 

Thanks and Regards

Re: [MW:28151] Weld bead length

Hi

 

I rather prefer to use the word single "pass" instead of your single "bead" mentioned.

 

Bead is the maximum width of weld metal deposited either by stringer or weaving, which may be allowed Not more than 3 times of your diameter - practical limitation

 

Pass is the no of layers deposited either by single run or multiple run

 

Bead is NOT essential & isn't a code requirement in general case, but Pass has requirement.

 

Change in multiple to single pass/side is supplementary variable as per QW-410.9

What is the sequence used in your PQR ?

 

For Beads, There is restriction in Sec 8 –UCS 56 (4)(-a) for weld repairs after PWHT - The maximum bead width shall be four times the electrode core diameter

 

Since you are welding LTCS material, which have more effect on your impact requirement. Because of faster cooling rates and subsequent metallurgical effects.



Thanks and Regards

My quarry:-

1)As per the applicable Aramco Standard ( SAES-W-012) , for Manual Welding process PQR can be qualified to either ASME SEC IX or API 1104, but many are insisting to use API 1104 to qualify as it is a pipeline . So kindly advise

2) Impact test required?

3)Suggested Welding Consumables for a) SMAW only b) GTAW & SMAW

4)Contractor is insisting for all pass Downhill welding using cellulosic electode E7010 for all passes,to avoid baking and storage requirements of Low hydrogen electrode(E7018).Is it possible ?

5)Hardness required for PQR?

6)Can this PQR be used for welding API 5L Grade B joints, without re-qualification?

Apologize for the lenghty quarry, waiting your valuable reponses.

[MW:28146] BONNET CLADDING WELDING || GTAW || FILLER WIRE SELECTION

Dear team,

Reference to the above mention subject, i would like to know selection of filler wire when welding cladding material for following situation.

1. I have job having below M.O.C for heater bonnet, 
 CHANNEL PLATE M.O.C - SA 240 GR 304
 BODY FLANGE M.O.C - SA 516 GR 70
 CLADDING RING M.O.C - SA 240 GR 304
(also find attachment for design joint)

Now my query is on selection of filler wire, can i use following filler wire for above situation

1. ER 309 LMO - It is for root run between body flange and channel plate for above situation. 
2. ER 308L - For subsequent layer and final run.

Also can i use wps qualifying with following criteria?.

(see attachment-WPS-1)-For root run welding
(see attachment-WPS-2)-For subsequent & final layer welding.

Or i need to qualify additional wps using two filer wire.

Thanks in advance

Re: [MW:28143] Weld bead length

Greetings,

Debate regarding weaving starts with fact that many of WPS  states weaving as 3 times diameter, without any particular need. However, for 9 mm width, I believe no standard mandates multi-weave. At maximum, heat input can be measured and co related with pqr value.

By doing multi run, u can improve toughness properties. Start with left and again start with right and finish at the centre .

Re: [MW:28140] Weld bead length

Dear Steve,
Thanks for your suggestion, but my client asking us to start multi run welding after hot pass, actually we are doing multi run for cover pass. As it is very difficult to weld multi run in narrow groove.

All,

Your client is right, multi bead welding  for cover pass - with SMAW - ensures fine grain weld metal and eliminates the risk of undercut which is the result of high amperage and incorrect electrode control.

Re: [MW:28136] acceptance edition of asme

Hi

I am unable to understand your question fully. 

 

Your plate is already produced / certified  before issuing  2017 edition, you can't do anything.

 

Even, Supplier can't provide you same MTC with same heat number or batch numbers !!!

 

Pl refer attached screen shot from "Sec IIA-P2 mandatory appendix ii Basis for use of acceptable asme, astm, and non-astm Editions" which may be helpful .

 

Anyway, you can use that raw material said by earlier members on this topic




Thanks and Regards

You need to compare with 2017 edition, if found fulfilling all mandatory requirements then you have to recertify as 2017.
