Re: [MW:27088] Macro Photograph of PQR & Joint Preparation

Dear sir,

1. If you looking for complete penetration then PQR rejected with following details for understanding.

Yes it will be like concave, I agree with you . Until it not fully penetrated will not get fusion . These is problem due to gas cup nozzle size diameter sticking with faying surfaces of wall thickness & higher arc length not advisable in welding.

Generally, AWS D1.1-2015 PG 97 Preqaulification . Will give you idea about root opening range from Min 5 to Max 12 mm ( tolerances added ) in your case 4 mm.

Thanks & Regards

Dear Dinesh,
Thanks for Quick Reply appreciated .

Sir,
The Root Gap is 4mm we are welding it FCAW process Size is 1.2, it can be fusion with backing plate.

However As per the AWS 4.9.1.1 (3)the weld shall be complete fusion (fig 5.4) . If we refer Macro photograph it is not fused with backing plate also it is in concave fusion. Can be passed or reject the PQR.

Re: [MW:27082] distance between welding joints

ASME code does not specify requirement of minimum distance between 2 circumference joints.

Some customer like EIL ask for minimum 300 mm distance. HAZs of both joint should be kept separated to the extend possible

Hi Hani,

Please see the attached datasheet for your reference. It's the data sheet from the OEM. It's not clear from your email, what's the thickness to be welded. However welding with 100 Ksi (UTS) welding consumable would be challenging, cracking may occur for any unspecified reasons.

Also use the welding products of reputed vendors. Also ask for diffusible hydrogen test results and the CE values of the welds (equal or less than the BM),so as to minimize cracking while welding. This is in addition to application of preheat and control of interpass" temperature.

Note these steels are of very high tensile steel, hence application of preheat and control of interpass temperature has to selectively decided , upon consultation with the OEM and consumable vendors.

[MW:27070] RE: 27062] Welding of PLATES STRENX 700

Hi Hani,

Please see the attached datasheet for your reference. It's the data sheet from the OEM. It's not clear from your email, what's the thickness to be welded. However welding with 100 Ksi (UTS) welding consumable would be challenging, cracking may occur for any unspecified reasons.

Also use the welding products of reputed vendors. Also ask for diffusible hydrogen test results and the CE values of the welds (equal or less than the BM),so as to minimize cracking while welding. This is in addition to application of preheat and control of interpass" temperature.

Note these steels are of very high tensile steel, hence application of preheat and control of interpass temperature has to selectively decided , upon consultation with the OEM and consumable vendors.

Thanks,

P.Goswami.P.Eng, IWE.

RE: [MW:27072] B31.1 PWHT for P11 WELDOLET requirement.

A 16-inch diameter pipe of schedule 120 has a 1.219-inch thickness.

An 8-inch diameter pipe of schedule 120 has a 0.719-inch thickness.

Since the 8-inch weldolet is SA-335-P11, presumably so too is the 16-inch pipe, which is an ASME P-No. 4 classification.

Presuming that the weldolet attachment weld is a full penetration weld into the pipe, then the controlling, or governing, thickness of the weldment assembly is 1.219 inches.

Therefore, the PWHT soak time must be a minimum of 1-1/4 hours.

However, it there is a finishing fillet weld whose throat thickness exceeds the pipe thickness, then the throat thickness governs the PWHT soak time, at 1 hr/inch of thickness.

Regards,

D. Thompson

hello.

I need to know about PWHT time for RUN PIPE 16" S120 to 8" S120 P11 WELDOLET PWHT hold time. if anyone know how to figure this time please guide me.

thank you.

Re: [MW:27072] WPS for A105

Yes. New PQR

Dear Experts,
I have a WPS qualified as per ASME Sec IX for ASTM A106 with AISI 4130.Now we have a requirement to weld A105 with AISI 4130. As I understand 4130 is unlisted material as per ASME and we need to qualify WPS every time. Kindly confirm the same or advice. Or can I go ahead with same WPS as there is no requirement for Impact testing.
Thanks in adv.

Re: [MW:27072] Crack after tack welding by using E6013 electrode

Yes, it is not necessary to bake it but to be kept in Quiver at 120°c. It is rutile based flux which is having >15<30ppm hydrogen level, to be kept as it.

one of inspector tell me its not neccesary to backing of 6013 but its packing condition, physical condition must be observed before use.
Dust and material condition may be problem.
grade of material and bcause its for low grade material purpose for welding..afford for tack weld in uppergrade ,7018 is better option for tack also in uppergrade
