Modelo de maturidade aplicado à células de soldagem robotizada: uma proposta baseada no modelo CMMI

Abstract

The high competitiveness of the industry today makes the search for modernization and improvement in processes become fundamental. The automation of welding processes offers numerous benefits for companies, ranging from higher productivity and welding consistency to lower costs for production, labor and materials, safety and quality. Industry 4.0 proposes to make the industry even more automated, so that machines equipped with sensors will be able to communicate with each other and thus make the process even more efficient and allow for real-time monitoring of what occurs in the welding process, also providing that the machine or robot is the process quality inspector. In view of this, it is noticed that barriers arise so that automated welding projects do not reach the expected result due to internal and external aspects. A maturity model is a way to assess how skillful a company is to manage and implement its projects, this means that it enables the identification of the maturity level and, thus, helps the company to define the best path for full success of the project is achieved. Among all the models that help in the assessment of maturity, CMM can be considered as its firstborn. There are several ways to validate a maturity model, including the one proposed in this article, through the evaluation of specialists in the field of robotic welding and users of the systems. The validation of this model was successful because, as proposed, all the average scores obtained were above 3. As a main result, this work presents a maturity model focused on robotic welding cells, which is a gap in the existing literature.
