Welding of 9% Nickel

[Jeffro]

Can anybody give some information on the welding of 9% Nickel steel

It depends what material configuration you want to weld. Is it pipe, plate?

You certainly have to perform certain preparations before conducting the welding operation.

Starting with a qualified PQR and generating a WPS would be a good start.

There is good information on

http://www.asme.org

I hope that this is of some help,

Hi izamil

I once worked for a company called RC Technical Welding & Fabrication, and a guy there called Raul Cardona (he's the President) but can weld anything to anything. Have a chat with him at 281-933-6004

needs PWHT . You havnt said if its pipe or if its new or old ...the new grades have different welding requirements they have vanadium in them and can be trickier

See the website for NIDI. It has a lot of information on 9% Ni steel welding. Also get in touch with Esab/Lincoln. They have specialized consumables of the type NiCrMo6 for weldoing these alloys.
