Re: [MW:18556] why ferrite measurement is always cheking prior PWHT.

It has to be before PWHT otherwise heat treatment itself can cause sigma phase embrittlement or 885 F embrittlement of austenitic stainless steels; chances of which increase with higher ferrite content. Therefore, in order to perform a heat treatment without having any possible embrittlement, a prior measurement of ferrite content is necessary.

[MW:18544] RE: 18541] 4'',check valve bad surface finishing

Dear Ezat

This casting is a defective casting could be an old and used, as now a days
the valves suppliers
pick up the scrapped castings also and use them after a bit of
cleaning/painting. This is clearly
seen in this case as the neck shows the signs of having some sort of putty
filled and dressed up.

The other possibility is that it is a 3rd Grade casting used to meet the
urgent requirements.

The recommendation is that IT SHOULD NOT BE ACCEPTED.

Re: [MW:18545] 4'',check valve bad surface finishing

dear sir,

 i think ,to adjust hexagonal nut face of it as it forged there is chances of nut get tightened in tapered ,which makes uneven stresses at tightening.

Re: [MW:18540] Current & Voltage Ranges for WPS

Hi,

As a general guide you can take 25 to 30 times the electrode size for Current (Amps). The Welding consumable manufacturer will give you the recommended Amps and Polarity.

Just my 2 cents.

Re: [MW:18538] Current & Voltage Ranges for WPS

Hi Kishore,

you can get those recommended datas from manufacturers Catalogues , like ESAB, Hyundai, Lincoln, Thyssen,  whatever brand you have selected.

for each size and the position of welding .

Before making PQR, you should always refer to the welding manufacturer's recommendation for Amps, Volts, polarity, type of coating, AWS Classes etc .

Cheers ,

You can use AWS/SFA E 316L-15 ( IS E19.12.2.LB20), an extra low carbon 17/14/2.5 Mo type SS basic coated

electrode with good corrosion resistance qualities.

This electrode is exceptionally good for welding AISI 316,316L, 317L & 318 type  material and provides a maximum

of 2.0 % ferrite . Such electrodes are designed for urea reactors and similar chemical equipment  used for temperature

services.

Typical chemistry:

C - 0.03 max.,         Mn 1.0 to 2.50,        Si- 0.20 to 0.45,          Cr – 17.0 to 18.50,         Ni – 13.0 to 14.0,     

Mo- 2.0 to 3.0,         S/P 0.02 max.                Ferrite content – 2.00 max.

UTS: 520-630 Mpa.         El % – 35 to 45     &     impact of 60 to 100 joules at 27±2⁰ C.

 

On same basis,  E 316-L – 16 (LF) type special  Electrodes are also available with ferrite less than 0.50%.

C - 0.03 max.,         Mn 5.0 to 7.0,        Si- 0.30 to 0.80,          Cr – 17.0 to 20.00,         Ni – 13.0 to 16.0,     

Mo- 2.0 to 3.0,         S/P 0.02 max.                Ferrite content – 0.50 max.

UTS: 520-630 Mpa. El %– 35 to 45 and impact of 30 to 75 joules at -196⁰ C.

Corrosion rate as per ASTM  A262 practice C  is 0.50 grams per m²/hr. Max. – 22 mpy.

 

All above electrodes are made to order  and may be available with leading electrode manufactures

like Adore, Esab, D & H, GE  and others  in our country.

Similarly you can scout for equivalent TIG  filler wires also after stipulating  your requirement from

manufactures from abroad or any  of their local agencies in India.

As per my opinion,

1. check the ferrite number of the base metal. 

2.Select a consumable batch having a ferrite number such that the average ferrite number of the base metal and the consumable is with in the range what required for you. Normally after welding an average ferrite number will be in the weld.

3. Do a sample weld and check the ferrite number. 

4. For the same manufacturer and brand name there will be slight variations in the ferrite number. So check the batch certificate and select a batch having a low ferrite number. Also do a small weld pad and check whether the ferrite number you are getting (Using your ferrite meter) is same as in batch certificate.

5. Also

keep the heat input to the minimum possible and keep the cooling rate to the minimum possible.

Dear Mr Ankit

i) The weld ment Ferrite to be checked after final Weld However the depth at which the ferrite to be checked depends upon spec requirement

ii) For  to get Ferrite between 2-5 is very low hence generaly Nil Ferrite consumables are to be used (also Basic coated electrodes are being used) where you require to take extra precaution during welding to avoid Hot Crack(Shrinkage Crack)

Dear Exerts,

 

Kindly suggest on following issue

We have a job on which ferrite content test is essential. we are welding with root run by GTAW & sub sequent layer by SMAW. Please confirm whether it is essential to check the ferrite content of the root or final weld.(top of the weld.)

Base Material-SA 240 TP 316L

Filler Wire/Electrode:- ER-316L & E-316L

Also our requirement is 2FN to 5FN kindly suggest any filler wire/Electrode manufacturer.

 

Regards
