Re: [MW:5546] Active TIG?

Dear Mr Prasad

I have no practical experience on this process, however as far as i know, backing gas is any way required in this process too, active flux acts as penetrating agent only for deep penetration.

Dear Mr. Raghuram,

 

I have gone through the A-TIG process use on SS pipes. Will this flux aovid the root oxidation.  In piping we use Argon gas back shielding to avoid root oxidation.  This paper does not talk about oxidation.

Dear kesavalunanda,

 

 Active-TIG welding ( hereinafter called as A-TIG welding ) is a welding method capable of drastically increasing further its penetration depth than in the conventional TIG welding by applying an active flux on the surface of steel product placed on the welding line. This welding method was proposed in 1960's, and is practically applied so that it can be easily used by the progress of recent research and development. By this, a drastic efficiency improvement can be materialized in TlG welding, drawing remarkable attention to it. which is such a new welding method.welding.
