For 1" RT technique suppose to be superimpose  technique(DWSI) ,so we need to calculate this way 

Double the thickness 4.1+4.1=8.2 and one reinforcement 1.5mm for 1" welding

0.20/9.7*100=2%

Dear sir,
Thanks for reply.

I want make clear my concept about sensitivity.
My point is that
1) sensitivity= thk of visible wire/ base metal thk * 100 ,
is it correct formula or not.

2) Secondly, according to client,  sensitivity means 2% of base metal. It will comes to 0.08mm for 4.1 mm thk base metal. Means, we have show IQI of 0.08mm.i.e. 1st wire of set A.

Request all experts, pls clear my concept about 2% sensitivity.

Regards
Prasad
