Yes, everybody will say that touch time's happens in their career as an inspection engineer, some at the time of an inspection, some at the time of giving a decision and some at the time of sign-off of an item.
There will be some situations which inspection engineer will repetedly face during inspections, irrespective of projects.
Some good resolutions for such situations are discussed below.
See the situation which happened at the time of survilence inspection:
At the time of site visit it is found that there is an heating quiever where 2.5dia E7018 electrodes are mixed up with E8018 B6L,3.5 mm dia electrodes. The assistant to helper says that he has not given any 2.5 mm dia electrodes to welder and welder says that he has not used any 2.5 mm dia electrodes. In an around the 18",SA335 Gr P5 joint, which is welded, there was structural welding going on using E7018, 2.5mm dia. The supervisor incharge requested to ignore the issue and the welder is a reputed welder of that organisation having good track record.
What will be the decision to be given as an inspector?
The instant and most common decision, most inspectors will give, is to cut and reweld the joint.
What my inspector done was, he checked for the electrode bits around the job and it was found that all are of E8018 B6L. He then gone to electode baking/storage area and checked for the mixup of electrodes. Both situations are found favourable. Then he gave the decision to continue the welding after ensuring the removal of all the E7018 electrodes from the quier. A tool box talk was given to the welder assistant and welder to ensure such issues. Instruction was given to the electrode baking area incharge and his assistant, to issue electrodes after ensuring that the quier is empty and no bits of electrodes are in it.
