About

Jukka Martikainen is a prominent Finnish welding engineering researcher whose work sits at the intersection of industrial automation, advanced manufacturing processes, and materials science. Best known for his contributions to robotic and mechanized welding technologies, Martikainen has helped drive the transition away from manual welding in hazardous environments toward sophisticated sensor-based robotic systems — a body of work reflected in his most-cited publication on robotic arc welding sensors and industrial programming (2015, 125 citations), which has become an important reference in the field. A significant portion of Martikainen's research addresses the welding of dissimilar and non-ferrous metals, particularly aluminium alloys, motivated by the transportation and energy industries' growing demand for lightweight, high-strength structures that reduce fuel consumption and emissions. His paired 2014 studies on gas metal arc welding (GMAW) processes for dissimilar metals — collectively accumulating 80 citations — demonstrate both his technical depth and his awareness of real-world industrial challenges. Martikainen has also investigated the material properties of high-strength aluminium alloys under welding conditions, exploring how surface chemistry and process parameters influence structural integrity. His work collectively provides researchers and engineers with practical, evidence-based guidance for implementing advanced welding solutions across automotive, aerospace, and energy applications.
