Welding 20ga Stainless Steel without distortion

Friends
I am inquiring to see if anybody has some helpful ideas to weld the project that is in the picture without the distortion. We have been using GTAW for the welding but have been unsuccessful to do it without distorting the shell in between the nozzles. Thank you in advance.

we have now removed the 20ga section and going with 10ga. This will help to minimize the distortion. Thank you all for your input.
tbuelna: if i may ask what is a joggled hole? The nozzle shown is a pad flange that is welded to the inner shell with a cone welded to the pad for the lagging to be welded. It is the lagging that is distorting VERY BADLY. We have since removed that section of lagging and are going with 10ga now which should help alot.

I have seen cases where they raised a flange 90deg to the shell and then placed the inserts into them for welding. The reinforcement will minimize distortion.

We are back stepping the welds and skipping around to minimize heat input.

We are unable to use brazing at this time due to not having a procedure and to little time to make one.
We have successfully completed the welding without distortion but only by switching to 10ga.
I will try to get a picture uploaded today.
Thank everyone for the comments and suggestions. It is greatly appreciated.
