For CVN test min thick qualification 12 mm to unlimited for 25 mm thick weld coupon plate but we need below 12 mm plate thick qualification we have taken 06 mm weld coupon plate thick. but standard mentioned... minimum thickness qualification 03 mmwe need 03 mm thick ness to unlimited thickness QUALIFICATION what should do..a) either required two weld coupons 25 mm and 06 mm thickness those 25 mm weld coupons complete the limite 12 mm to unlimited and 06 mm weld coupons complete the limite 2T that is 03 mm to 12 mm Thick....Please clear this concern..
