[MW:3309] Re: application of SS Flux cored wire for GTAW, SFA 5.22

Yes, STT is a good option only if you could use GMAW process. And its worth an investment only if such jobs are regular.

Besides STT, even Miller Electric has developed their patented technology RMD - Regulated Metal Deposition. Machine Model is Pipepro 450. Its somewhat similar to STT and a little more to offer. check www.millerwelds.com

Dear members

We have typical vessel (site assembly), where backing gas arrangement could not be done for a stainless steel joint due to Safety (confined space), as well as space constraint.

One of the options will be using flux cored wire for GTAW.

Please share your view on these consumables for root pass of GTAW Stainless steel; where backing gas application is impractical, any body used these consumables?

Kobleco is manufacturing these wires under TGX series, any other manufactures who has similar product for this application?
