Welding Inspector:- It is not requirement for a welding inspector to be able to weld,neither does a welding inspector require an in depth knowledge of welding engineering,although some specific knowledge in these areas is essential.For certain contracts it is also necessary for a welding inspector to have a good working knowledge of other related subjects,e.g.radiographic interpretation and post-heat treatment.
The presence of welding inspectors during welding will almost certainly reduce the number of weld defects and metallurgical problems which could otherwise occur,which will in turn,reduce the overall number of failures in service.When an item has failed,it usually means that cracking or fracture has taken place.
There are many types of cracks associated with welds,some of which may initiate at the time of welding - process cracks or years later - in-service cracks.In both these cases,stresses,metallurgical problems and existing weld defects may have contributed to the cause of the cracking.
