[MW:33191] Re: Welding Process for Rail Material A75 ( DIN 536)

Dear Vinu ,  

please  refe tthe AWS standard / ISO standrds for this  flash but welding / thermit welding of rails  

AWS D15.2/D15.2M- Recommended Practices for the Welding of Rails and Related Rail Components for Use by Rail Vehicles to get some basic idea about qualification  and ask your cleint are they having project specifcations for  rail welding.

type of tests required for any welding procedure will be confimed by welding code , contrsctuintion code& project specifications& recommended practices applicable for a project .

common test fro rail welds are 

NDT - RT/ UT(PREFERABLE) , MT

weld chemistry 

macro

hardness

metallurgucal test

bend test 

TRANSFER TESTS  

 MICRO (METALLURGYCIAL ANALYSIS )

Thanks & regards,

Re: [MW:33190] RE: PWHT Segment Wise for 9 Meter Dia Vessel

Dear Jayakumar

Not exactly. UW 4-(a)(8) covers everything else. As i mentioned it is not a preferable/recommended method (either go with Modular or Internal firing are most appropriate). 

"provided that other measures (based upon sufficiently similar, documented experience or evaluation) are taken that consider the effect of thermal gradients,

all significant structural discontinuities (such as nozzles, attachments, head to shell junctures), and any mechanical loads which may be present during PWHT.

The portion of the vessel or component outside the soak band shall be protected so that the temperature gradient is not harmful".

It is straight forward method for cir seams, however for long seams you have to work a methodology for placing coils locally using WRC 452 guidelines, probably  supplimented with an FEA to check thermal stresses

Dear All,

 

We are fabricating a Vessel of Diameter 9 Meter at Site, requires PWHT: Material Grade SA 516 Gr. 70.

 

 For Circumferential Joint PWHT can it be performed Segment Wise as diameter is more??

 

Pl. Confirm as per ASME Sec VIII Div 1 can it be done in Segment Wise.

Dear Vishal 

As I understand  correctly , the vessel circumference is 9 mtr  and  your query is that you want to carry out the PWHT of the Circumferemtial seam in segments.

The answer is No . You have to carry out PWHT  of  ENTIRE Circumferencial joint in ONE cycle.

You can do it by LOCAL PWHT method by wrapping Electric Resitance Coil on job and attaching job thermocouples.

Many HT contracter are doing such type jobs regularly.

Re: [MW:33177] RE: PWHT Segment Wise for 9 Meter Dia Vessel

What diameter can your furnace accommodate?. 9 Meter seems to be Big.

There are some options if your Furnace cannot accommodate.

1.  Try for a Temporary furnace with proper insulation and Heating arrangements. Hope there are some subcontractors available.

2. Try for LOCAL PWHT of the seams.

3. Below option may be useful if you have difficulty accommodating the Length in one Heat.

Thanks & Regards

Re: [MW:33162] PQR test required

RT is not mandatory according to ASME sec IX. 

1. It is to help you for destructive testing sampling you can discard the defective location.

2. Most of the customer expects RT examination

3. Additionally you have an provision to prefer UT in lieu of RT
