Thanks you all 

Question 1:  WPS was established in 2008, can it be used now?

Question 2: for a 3 meter dia tank how to give purging to do root weld with GTAW.

Hi.

Both are same P.no8/Group.no1.

So no issue to use the old WPS.

But must be consider,

1. Special requirements other essential variables such as thickness range, 

And supplimentry essential variables,

Based on particular project requirements.

2. Approval of new client.
