P 10Haidê Kronbauer MartinelliABSTRACTThe shipbuilding industry, from its inception to the present day, had evolved, and followingthe needs of the industry, classification societies were founded. They, as non-governmentalorganization, regulate the fabrication of new ships or offshore structures based on their ownestablished codes, rules and standards. As, nowadays, the most widely used joining techniqueon shipbuilding activities is welding, these welded joints must be certified and ensured thataccomplish the quality expected and allow repeatability for the specified materi
