An Optimal Design of Multifunctional Vision Sensor System for Welding Robot

To meet the requirements for automation of welding robot, the author suggests an optimal design of multifunctional vision sensor system for welding robot, which have many features, such as remote controling, resisting disturbance from arc, welding environment identifying, initial welding seam guiding, seam tracking, penetration controlling and so on. The vision sensor is used to acquire some ideal images of stainless steel welding process experiments. It will set up the foundation for the later robot welding quality control. The multifunctional vision sensor presented in the paper is showing important practical value as it is simple in construction, low in cost and strong in practicability.
