The paper presents an analysis of the state of research in the field of steel structures elements strengthening using carbon fiber reinforced composites (CFRP), highlighting the importance of the subject as well as the results of the presented studies. The research results analysed in this article consistently highlight the potential of CFRP composites to significantly improve the fatigue behaviour and extend the service life of welded steel structures, in particular, through strengthening techniques based on external application. Practical case studies reinforce the feasibility and benefits of using CFRP in various industrial applications. Although there are still challenges and limitations, such as high costs and the absence of dedicated design standards or norms, continuous research and development efforts actively contribute to overcoming these obstacles and pave the way for a wider adoption of this technology.
