Projeto de um Dispositivo de Inspeção Para Juntas Soldadas Destinado à Indústria do Petróleo

Abstract

The use of the TOFD (Time of Flight Diffraction) Ultrasonic Technique for identification and dimensioning of internal cracks in welds is an efficient and worldwide method. In the Oil and Natural Gas Industry many structures such as ships and platforms are applied in their production cycles. Therefore, their integrity is fundamental to the safety of installations, crew and the ecosystem. In this context, the Automatic Ultrasonic Inspection Device for Soldered Plates was developed. It was created with the purpose of practically and reliably evaluating the integrity of flat top-level welds on large metal plates. Another feature of the prototype is its simplicity and low manufacturing cost. It consists of trolley and inspection module. They move over the weld bead, performing a complete scan and sending the data for interpretation to external instruments. Its project was developed in the Laboratory of Integrity and Inspection of the Federal University of Paraíba, LabII - UFPB and its manufacture took place in the Mechanic Workshop of the UFPB. The prototype is in the process of being assembled and adjusted. The inspection device will also be used for educational purposes. It will be used as a study bench for engineering students of the institution. The design of the prototype were carried out the steps of sizing, design of the pieces, choice and purchase of materials, machining and assembly of the set. Throughout, this work will be presented the details regarding the stages that led to its creation.
