TGX and 308H Electrode weldability

[Lynred]

To all,

Anyone of you could give me technical data for TGX and 308H electrode weldability?

Thanks,

Lynred

What is the application/material specification for TGX? More information regarding this material would help.

metenger,

I looking for an eletrode that can be used without back purge to weld TP304H ss material. Kobe does not have TGX type electrode to weld it. I want to know why it cannot be done.

Appreciate

cheers,

First off probably there isn't that much demand for a flux cored 308H TIG Wire. If you have noticed the fluxed cored SS MIG wires are just beginning to get popular and available.

Flux cored TIG wire is both old and new. They have come on the seen stayed a little while and then disappeared. I first became acquainted with them in the early 60's. They were not very good. They have come back several times and the same thing happened.

In looking around I don't see but 6 alloy wire currently available in flux core SS TIG wire, then by only from limited suppliers.

For another why, it has always been a little problem welding the H alloys in getting to weld metal chemistry to match the base metal chemistry. On several occasions we have had to go to a higher carbon +H type electrode to get the proper chemistry. I would suspect that the loss of carbon could be a problem with a 308H cored rod.

Can you comeback with information on what you are trying to weld. Depending on the end use of the welded joint there are other ways to approach your problem.

You might give these people a call. Cor-Met might have something if there is a sufficient quantity.
