[MW:35182] AWS D1.1 Material Groups and PQR Qualification

Dear Sirs,

if we are qualifying a PQR with EN10025 S355JR to S355JR is this PQR qualifies to weld S355J2 to S355J2?

Re: [MW:35183] AWS D1.1 Material Groups and PQR Qualification

Dear Biju,

It's unlisted to unlisted material qualification, specific material grade.

Change in material grade requires new qualification as per AWS D1.1

Re: [MW:35184] ISO standard for qualification of WPS and Welders on Alu Zinc material.

Dear,

Thank you for your reply. My doubt is which section we need to refer ISO 15614-1 for steel or ISO 15614-2 for Aluminium. Aluzinc is coating on steel sheet.

Thanks & Regards

Ganesh

[MW:35184] Minimum base metal thickness qualified for prequalified Fillet joint ( AWS D1.1)

Re: [MW:35188] AWS D1.1 Material Groups and PQR Qualification

Hi Baiju,

It depends on your operating conditions. If you don't require J2 impact conditions, meaning only strength is the design consideration, then you can use S355 JR instead of S355J2 (considering impact conditions do not apply).

However, as per the code, unassigned material requires a separate PQR.

[MW:35190] Re: WELD DISTANCE AS PER ASME

ASME does not outline this, whereas some British standards, such as "BS 4515:2009," require 4 times the wall thickness of the thinner part to be joined.

ARAMCO says in "SAES W11" spacing shall be 3x wall thickness or 20mm, whichever is greater.

If you're working on a project, double-check the specifications or applicable code. If you're preparing for an interview, remember both.

Re: [MW:35191] Re: WELD DISTANCE AS PER ASME

Dear Sir,

The minimum distance between welds is specified as follows: 

 1. ASME B31.3 Process Piping:

For Circumferential Welds: The minimum spacing between circumferential welds must be at least four times the thickness of the thicker component, with a mandatory minimum of 25 mm (1 inch).

For longitudinal welds on adjacent shells or sections, the required distance should be no less than five times the wall thickness of the thicker section, with a minimum spacing of 38 mm (1.5 inches).

2. AWS D1.1 Structural Steel Welding:

 The distance between welds in structural steel applications should be at least four times the thickness of the thinner member being joined, with a minimum requirement of 10 mm (0.4 inches). 

3. API 1104 Pipeline Welding:

For adjacent girth welds, the minimum spacing must be at least one pipe diameter, or 100 mm (4 inches).

Best regard,

Mostafa Daif, Cweng,

Re: [MW:35194] Dressing # Grinding ( PQR & wqt )

On weld caping dressup not effect for mechanical testings. Weld caping (above based metal) consider as excessive material. So we can allow start ,stop point dressup.

On this case code is silent.

Review the MTC of plate material and tolerance of specific heat / lot number and then identify the thickness of the lowest shell course thickness.

 

For lowest shell course, one spot radiography on every vertical joint.

 

Hope this will clarifies your doubt.

Re: [MW:35175] Filler wire for 321H

If GTAW, use 321 H if it is available otherwise 321 itself. IF process other than GTAW, use 347

Re: [MW:35176] Filler wire for 321H

Hi,

You can use 321 with higher carbon content .

You need to ensure carbon content of filler wire .

The above mentioned test coupon impact and hardness testing failure. Impact value is getting lower and hardness value getting higher. 

The impact required average value is 55J and hardness max value is 225BHN but the impact actual value getting 22J and the hardness min actual value getting 208BHN.

What is the exert problem for this failure?

Please give us a deeper explanation for this failure. What is the solution?

Re: [MW:35161] Reg: Mechanical Testing Failure Analysis

Dear ,

- P22 is used for creep resistance ... why go for -29C temp. ... u can check with engineering department .

- for your case try to modify joint design for minimizing the weld cross section as much as you could ... go for the lowest available SMAW electrode diameter , GTAW wire diameter .. try to use string passes and avoid waving technique .. temp. after PWHT to be controlled during cooling process

- for hardness i see it is OK .. just Charpy is the point to concentrate

- if results still not OK .. check with engineering to go fo 1% Ni electrode but it will be differ than base metal chem. composition Cr% 

 

Best Regards ,
