Vision-technologies used in welding robots by means of automation is a crucial step in technology based on any industry. The system coupled with top of the line machines and algorithms is able to significantly find faults or errors in the welding done in the primary stages of the process. This helps welds to be of better quality and increases the efficiency of the production process within the industry. With the changing times, the manufacturers requirements for a rational machine as a vision-system increases in order to keep up with the already developed countries standards.
