Welding
(OP)
Hi All,
I am a fresh graduate, just graduated 3 months ago and have since been working in an oil and gas company. I have some questions regarding welding and like to seek some professional helps.
1. My manager told me welding is not done on AISI 41XX. May I ask why is that so? If that is the case, then my next question will be (2)
2. What are the materials that can use for welding?
3. The maximum permissible Carbon Equivalent value. I believe this is used in welding. Yes? No?
4. A colleague of mine requires weld repairs for his test flanges which are made of AISI 4130. My manager suggested to use 625 overlay. Is there any rational behind this?
I think I want to know more is, what kind of materials are suitable for welding process and why is it so.
Thank you and appreciate the great advise given.
Thanks,
Jeffrey

Why can't you approach your manager about this and ask him the same questions?
This would show the manager you are keen and interested to learn.

Hi Desertfox,
My manager is busy with his works. He prefers us to be independent and find the solutions ourselves.
Thanks.
RE: Welding
If weld repairs to 4130 flanges are required because of corrosion, the use of E/ER NiCrMo-3 or other NI-CR-MO alloys may well be warranted.
RE: Welding
Thanks! The information you provide is very useful.

It might be wordt buying that one (or googling for a copy, perhaps...)
