[MW:3282] Re: [MW:/] Re: application of SS Flux cored wire for GTAW, SFA 5.22

Sir,

May I know the thickness of the pipe and of grade of SS? 

I do not have any idea of Kobelco or Metrode product. In my opinion, Magna 39FC TIG will be able to do your job without Back Purging. The product is expensive but it is designed for jobs which cannot be back-purged or even sometimes even to eliminate back-purging setup. It will leave a very fine Slag in the inside of the pipe  which will easily come off with a little tapping after welding. And offcourse the slag can be easily drained off with water. The weld will pass X-ray.

Its best for the root, rest of the fill-cap can be done with any wire. 

If you are interested, contact me, i should be having its literature OR you can check www.magnagroup.com

Regards

Since purging option is ruled out due to space constraint. that is the reason for switching to flux cored wire

Hi,

I have tried in the past for mock up using Kobelco and Metrode GTAW Flux Cored wires. At site it depends upon accessbility of weld joint and welder skill .

If possible , purge the joint with argon / nitrogen and weld with GTAW flux cored wire .

Alagu
