Mr José Luis Velázquez De La Hoz
PhD Student
Summary
Mr. José Luis Velázquez de la Hoz works full-time in industry as a Principal Engineer. He is also a doctoral researcher at the Mechanical and Aerospace Engineering department. He holds an MSc in Engineering from 香港六合彩搅珠直播 University of London. He is an International Welding Engineer and International Welding Inspector at the Comprehensive Level by the Deutscher Verband für Schweißen und verwandte Verfahren, DVS, in Germany. He is a UK Engineering Council Chartered Engineer and a member of TWI.
Jose is researching the development of a Digital Twin for conduction laser micro-welding for Smart Manufacturing applications. Widely used in high-value manufacturing industries like e-mobility, medical, automotive, aerospace, or pressure equipment fabrication, conduction micro laser welding is characterized by small, shallow melting pools in which viscous forces prevail over inertial ones. In combination with characteristically high cooling rates, the interplay between the melting pool drivers, namely capillarity and thermocapillarity, results in various welding geometries, which are highly complex to analyze empirically. Thus, a key aspect of his research involves the exploitation of advanced multiscale modeling of micro-laser welding and the design of innovative Reduced-Order modeling techniques to manage computationally expensive models. A central part of his study is the development of Physics Informed Machine Learning models.
Driven by the practical implications of his research in fabrication, additional examined concepts are Digital Manufacturing, Cyber-Physical Manufacturing Systems, Zero Defect Manufacturing, an innovative framework for an Intelligent Quality Management System for laser micro-welding, and the consequences of digitization for manufacturers like the vertical and horizontal integration of welding processes and organizations into welding business ecosystems.
