SAW welding // SA240 TYP201LN // consumable selection

[atul jha]

DEAR EXPERT

I am searching for welding consumables as per below requirement  for cryogenic vessel MDMT -196⁰ C 

Base material- SA 240 TYP 201LN.( UTS 655N/mm².

Imapct test- (-196⁰c,LE must be 0.38 mm,energy 34J.

Bend test at 4t,180⁰.

Previously I welded this material by Ni Cr Mo-3 filler wire and flux from a reputed manufacturer and result was acceptable all marine class surveyor.

At persent I am looking for  any alternative consumables which satisfy above requirements and cheaper than Ni Cr MO-3.

As required quantity is huge so I can go with unassigned welding consuambles also.

Guidance  regarding consuambles is highly appreciated.

Regards

Atul jha .

Dear Mr.Jha

If the material thickness is above 10mm ,you have no choice but to use Mo3 consumables.

Sir 

you may refer  ASMEIIA  for chemical composition and subsequently you may  proceed  effect of alloying element as I also don't have any specific paper regarding this.
