This paper aims to design a conceptual model of a Smart Product-Service System (SPSS) for Intelligent Welding System (IWS). To achieve this goal, a detailed literature review, analysis of the welding industry (WI), and a training-educational-design workshop on SPSS and IWS were conducted at a business partner, a welding plant. This allowed the researchers to develop an SPSS in which the tangible component is the IWS (welding robot, sensors, monitoring devices, supporting devices, network infrastructure), enriched with an intangible component, i.e., services and a digital component in the form of a platform and a mobile application. Focusing on specific problems, requirements, and needs of welding plant employees, the developed model aims to draw attention to important elements of the plant in the context of global digital transformation and environmental protection. Thanks to this solution, the WI receives several advanced innovations integrating digital technologies, services, and automation. Additionally, the approach to developing SPSS presented in the article emphasizes the need to combine theoretical knowledge with practical knowledge in welding. This contributes to developing innovative training, education, and design methods for innovative solutions in the digital era.
