A presente invenção se refere a um sistema e métodos com um dispositivo e um suporte de gravação lido por computador associados para pré-avaliação e treinamento de candidatos para o processo de qualificação de soldadores. The present invention relates to a system and methods with an associated computer readable recording device and carrier for pre-assessment and training of candidates for the welder qualification process.
O sistema da presente invenção também pode ser aplicado em processos de seleção de pessoal para qualquer outra função que exija um grau de atenção e habilidade manual mais elevado. The system of the present invention may also be applied in personnel selection processes for any other function that requires a higher degree of attention and manual skill.
Antecedentes da Invenção Background of the Invention
As operações de soldagem exigem adequação a requisitos rigorosos de engenharia e segurança. A realização de soldas inadequadas na montagem de certas estruturas e equipamentos pode resultar em acidentes sérios com prejuízos materiais importantes e, nos casos mais graves, incalculáveis danos ao meio ambiente e perdas humanas.  Welding operations require compliance with stringent engineering and safety requirements. Improper welding when assembling certain structures and equipment can result in serious accidents with significant material damage and, in the most severe cases, incalculable damage to the environment and human loss.
Assim, para diversas aplicações, existem normas técnicas para a especificação de procedimentos que serão adotados de forma a minimizar os riscos e garantir a qualidade da solda. O mesmo nivel de exigência é adotado no processo de qualificação de profissionais de solda. Thus, for various applications, there are technical standards for specifying procedures that will be adopted in order to minimize risks and ensure weld quality. The same level of requirement is adopted in the qualification process of welding professionals.
Os versados na técnica de treinamento destes profissionais sabem que este processo de qualificação é complexo e requer muito tempo de prática, dedicação de instrutores experientes, equipamentos adequados e consumo de materiais. Those skilled in the training technique of these professionals know that this qualification process is complex and requires a lot of practice time, dedication of experienced instructors, proper equipment and material consumption.
Ademais, em virtude do alto grau de habilidade manual, concentração e reflexo aos impulsos visuais, exigidos já durante o processo de qualificação do soldador, torna-se necessário realizar uma pré-avaliação da aptidão de um candidato a soldador para desenvolver estas habilidades. Moreover, due to the high degree of manual skill, concentration and reflex to the visual impulses, already required During the welder qualification process, it is necessary to pre-assess the fitness of a welder candidate to develop these skills.
Para evitar perda desnecessária de material e, de forma geral, tornar mais eficiente e menos dispendioso o processo de qualificação, diversas soluções técnicas foram propostas ao longo dos últimos anos. Vários esforços têm sido dirigidos para recriar um ambiente em que as condições da soldagem sejam simuladas por meio de recursos audiovisuais gerados em resposta aos movimentos do usuário. To avoid unnecessary material loss and generally make the qualification process more efficient and less expensive, several technical solutions have been proposed over the last few years. Several efforts have been directed to recreate an environment in which welding conditions are simulated through audiovisual resources generated in response to user movements.
Por exemplo, o documento US4931018, de 05/06/1990, descreve um dispositivo de simulação para treinamento, incluindo um capacete, uma pistola de solda e sensores de movimento, que simula uma peça a ser soldada em uma tela, produzindo uma resposta visual aos movimentos do usuário. For example, US4931018 of 6/5/1990 describes a training simulation device, including a helmet, a welding gun, and motion sensors, which simulates a part to be welded to a screen, producing a visual response. to the user's movements.
Desenvolvimentos mais recentes desta tecnologia fazem uso de recursos avançados de computação gráfica para conferir maior realismo ao ambiente simulado. Exemplos incluem o documento ES2274736B1, de 01/03/2008, que descreve um dispositivo compreendendo uma pistola de solda, sensores de posição e orientação, que gera uma imagem virtual em um capacete de realidade virtual. Newer developments in this technology make use of advanced computer graphics capabilities to add realism to the simulated environment. Examples include ES2274736B1 of March 1, 2008, which describes a device comprising a welding gun, position and orientation sensors, which generates a virtual image on a virtual reality helmet.
Por sua vez, o documento WO2010020867A2, de 25/02/2010, descreve um dispositivo similar, destacando as vantagens da geração de uma imagem virtual mais realista e em detrimento do treinamento das habilidades manuais ou "memória muscular". In its turn, WO2010020867A2, of 25/02/2010, describes a similar device, highlighting the advantages of generating a more realistic virtual image and to the detriment of training of manual skills or "muscle memory".
Tais tecnologias frequentemente têm alto custo e complexidade, além de não fornecerem ao instrutor dados suficientes para uma avaliação preliminar das aptidões dos candidatos a soldador. Além disso, os dispositivos disponíveis não permitem avaliar a evolução dos candidatos no desenvolvimento destas aptidões durante o processo de seleção e treinamento. Such technologies often have high cost and complexity, and do not provide the instructor with sufficient data for a preliminary assessment of welder candidate skills. Furthermore, the available devices do not allow to evaluate the evolution of the candidates in the development of these skills during the selection and training process.
Frente ao exposto, mostra-se premente suplantar as desvantagens apontadas no estado da técnica. Given the above, it is urgent to overcome the disadvantages pointed out in the state of the art.

Vantajosamente, o sistema da presente invenção é de construção simples, com um custo de produção e instalação muito menor que os dispositivos de simulação atualmente disponíveis. Vantajosamente, o sistema da invenção é capaz de criar curvas de referência para os candidatos com padrões pré-estabelecidos de soldadores experientes, bem como comparar desempenhos dos candidatos durante o processo de seleção e treinamento.  Advantageously, the system of the present invention is of simple construction, with a much lower production and installation cost than currently available simulation devices. Advantageously, the system of the invention is capable of creating reference curves for candidates with pre-established standards of experienced welders, as well as comparing candidate performances during the selection and training process.
Conforme ilustrado na Figura 1, o sistema da presente invenção compreende um corpo de prova 102A e uma chave-teste 102B, conectados a uma unidade 101 que coleta os dados do teste executado por meio do corpo de prova e da chave-teste, e os transmite para o servidor 103, onde são processadas as comunicações e gerenciados os processos principais do sistema, além de fornecer uma interface gráfica. As illustrated in Figure 1, the system of the present invention comprises a specimen 102A and a test switch 102B, connected to a unit 101 that collects test data performed by means of the test specimen and the test switch, and transmits to server 103, where communications are processed and managed the main system processes, and provides a graphical interface.
Como se pode observar na Figura 2, a unidade 101, por exemplo, um CLP, responsável pela aquisição dos dados e pela comunicação com o servidor 103, está disposta no interior de uma caixa.
