During the PANNDT 2025 event, Karl Jauvin, NDT Instructor at the Centre de Métallurgie de Quevec (CMQ), shared the advances that are positioning the institution as an international benchmark in technologies such as 3D metal printing. Through an applied approach that combines research, development, business collaboration and technical training, the CMQ drives customized solutions for the metalworking industry.
From the laboratory to industry: a collaborative model
CMQ operates as an applied research center with a model based on specific projects with companies, where companies present specific needs and the center responds with comprehensive solutions ranging from initial simulation to final validation of the parts.
To achieve this, the institute’s team includes researchers, engineers, teachers, university students and even doctoral students. This synergy between academia and industry favors knowledge transfer, accelerates innovation and generates highly qualified talent.
The power of 3D metal printing
One of the most innovative thrusts of CMQ’s work is the use of 3D metal printing, which, unlike traditional plastic printing, is a process that uses metal powders, including aluminum and titanium. The center even has the ability to create its own alloys and atomize them to produce ultra-fine powders tailored to very specific technical requirements.
This type of additive manufacturing allows the development of complex components that would be very difficult, if not impossible, to produce with conventional techniques such as welding. Geometric accuracy, reduced material waste and design flexibility are just some of its advantages.
Specific application: repair of a pipeline
During the interview, Karl Jauvin explained the specific case of rebuilding a section of steel pipe that would normally require welding, illustrating the benefits of metal 3D printing. Traditionally, when an industrial pipe suffers damage or wear, the affected section is cut out and replaced with a new piece joined by welding. This process, while effective, brings with it certain complications, such as the application of heat that generates internal stresses, can deform the original part and alter its mechanical properties.
With the methodology developed by CMQ, instead of resorting to conventional welding, additive metal fabrication was used to directly fabricate the new pipe section, integrating the original geometry and functional requirements. Most notably, this part was designed to fit seamlessly with the rest of the system, without the need for subsequent adjustments.
By minimizing the application of heat, uneven material shrinkage is avoided, significantly reducing deformation and allowing the repaired part to retain its original dimensions. This facilitates reinstallation without affecting system performance or generating extended downtime.
Non-destructive testing as a pillar of the process
At CMQ, all parts developed undergo a rigorous validation system that includes NDT and destructive testing, to ensure that the components meet the quality and safety standards required by the user industries. Non-destructive testing allows for the detection of internal or surface defects without altering the part, which This is especially essential in components manufactured with additive technologies, where the microstructure can vary depending on the process.
Thermal spraying and functional coatings
In addition to 3D printing, the institute works with other technologies such as thermal projection, which involves projecting materials such as ceramics or even particles with molten diamond at high speed onto metal surfaces to create protective coatings. These coatings are applied to improve the wear, friction or corrosion resistance of components subjected to extreme conditions, offering a much longer service life.
Training as a development axis
Another key aspect is the integration of technical, university and even doctoral students in the center’s active projects, a strategy that not only strengthens practical training, but also ensures a constant renewal of knowledge.
Students participate from early stages in real tasks of the production cycle, such as computer-aided design, material preparation, 3D printing, quality testing and analysis of results. This model allows them to gain experience with advanced technologies and develop technical competencies aligned with the current needs of the industrial sector.
Perspectives and emerging technologies
The future of metallurgy is linked to the digitization of processes and the adoption of technologies such as 3D printing, computational simulation and intelligent inspection systems. By integrating advanced manufacturing with nondestructive testing and a strong educational component, the Quevec Metallurgy Center is consolidating its position as a strategic ally for the metallurgical industry that seeks to evolve without losing efficiency and safety.
