This paper aims to provide details of vision-assisted robotic welding technologies and their applications.


Following a short introduction, this paper first considers the background of vision-assisted robotic welding, the functions of the vision systems and the scenarios where the technology is of benefit. The main section provides examples of vision-assisted welding applications, together with details of the systems and products employed. Finally, brief concluding comments are drawn.


This shows that modern machine vision technologies, often based on lasers, can allow robotic welding systems to compensate for dimensional variations and errors, eliminate the need for complex and costly welding fixtures and act as an alternative to skilled human welders. This technology allows robotic automation to be deployed in welding applications where it was hitherto impossible, technically difficult or not cost-effective.


By considering a section of applications, this paper provides an insight into how machine vision technologies can enhance the capabilities of robotic welding systems.
