The present work proposes an empirical evaluation of real-time quality monitoring of MIG/MAG welding of dissimilar high strength steels DP800 and DP1000 in T-joints based on the measurement of the processes parameters. A new strategy is proposed to evaluate the quality of the welds of HSS materials using the ISO 5817 standard. From the obtained results, a correlation between the process parameters and the quality of the weld was established. An operational comparison between cobot and manual welding was performed based on their repeatability. The results confirm the higher repeatability of the ..read more

  The application of coatings to protect parts and components against various types of wear mechanisms is notorious in several industrial sectors. The coatings can be applied using different processes and alloys, being, without a doubt, an efficient alternative to provide an increase in the component's lifespan. However, this application favors the emergence of several operational and metallurgical challenges.   At first, it is important to highlight that each specific situation and application requires a different solution.The conditions of the tribological systems (component, coun ..read more

  Ensaios Não Destrutivos (END) são técnicas utilizadas na inspeção de materiais e equipamentos sem destruir ou danifica-los, sendo executadas nas etapas de fabricação, construção, montagem e manutenção. Ou seja, são realizados testes que atestam a qualidade de uma determinada peça, sem que ela seja danificada ou inutilizada.   As principais aplicações dos Ensaios Não Destrutivos podem ser encontradas em diversos segmentos industriais como automotivo, óleo e gás, aeroespacial, ferroviário, nuclear, dentre vários outros, sendo amplamente utilizados para verificar a qualidade nas inspe ..read more

  Non-Destructive Tests (NDT) are techniques used in the inspection of materials and equipment without destroying or damaging them, being performed in the stages of manufacturing, construction, assembly and maintenance. In other words, the NDT are performed to attest the quality of a particular part, without it being damaged.   The main applications of NDT can be found in various industrial fields such as automotive, oil and gas, aerospace, rail, nuclear, among many others, being widely used to verify the quality of weld inspections and to guarantee the integrity of cast materials, f ..read more

Do you know the new modalities of the GTAW process?   In the manufacture of pipelines, the first welding step, known as the root pass, is considered a critical step in the execution of the joining, due to its structural importance of support for the subsequent passes. Commonly, the root pass is performed by the GTAW (Gas Tungsten Arc Welding) process, also known as TIG (Tungsten Arc Welding), and then the chamfer is filled by the SMAW (Shielded Metal Arc Welding) or GMAW (Gas Metal Arc Welding), manually or automatically, causing difficulty in achieving the required quality.   The G ..read more

Você conhece as novas modalidades do processo de soldagem TIG?   Na fabricação de dutos e tubulações, o primeiro passo de soldagem, conhecido como passe de raiz, é considerado como uma etapa crítica na execução da união da junta, devido sua importância estrutural de suporte para os passes posteriores. Comumente, o passe de raiz é realizado pelo processo TIG (Tungsten Arc Welding), também conhecido como GTAW (Gas Tungsten Arc Welding), e então o chanfro é preenchido pelo processo de eletrodo revestido (SMAW) ou MIG/MAG (Metal Inert Gas/Metal Active Gas), de forma manual ou automatizada, ca ..read more

Do you know the effects of the hybridization of a welding process and its influences on the productivity and quality of the weld?   In the late 1970s, Steen W. et al. first introduced the hybrid LASER-arc welding (HLAW) processes. His studies, carried out at the Imperial College of London, clearly showed the advantages of combining a LASER beam with an electric arc for welding.   Through technological advances in the manufacture of high power LASER sources, and instruments that made it easier to understand what actually happens during the HLAW process, the emergence of a new an ..read more
