Automatic Tracking of Welding Line by Autonomous Mobile Robot for Welding of Plates. Tracking of Linear and Angled Welding Lines.

Seam Tracking of Intelligent Arc Welding Robot

Intelligent welding robots obtain a good quality of the welding results. Research on automatic and intelligent control of Arc welding is an important means for ensuring weld quality, raising productivity, and improving labor conditions. Despite its widespread use in the various manufacturing industries, the full automation of the robotic welding has not yet been achieved partly because mathemat...

Automatic Welding System Using Speed Controllable Autonomous Mobile Robot∗

A prototype of autonomous mobile robot with two vision sensors for automatic welding of steel plates was constructed. The robot can move straight, steer and turn around the robot center by controlling the driving speed of the two wheels respectively. At the tip of the movable arm, two CCD cameras are fixed. A local camera observes the welding line near the welding torch and another wide camera ...

Seam Tracking for Laser Welding with an Industrial Robot

Because of their construction and flexibility, industrial robots are suitable to be used, with a laser source and an optical fiber, for laser welding of 3D products. However, the positioning accuracy of robots are insufficient for laser welding. Also the product and clamping tolerances are too wide for laser welding. These problems can be solved by applying sensors, which measure the location o...

The autonomous detection and guiding of start welding position for arc welding robot

Purpose – The recognition and positioning of start welding position (SWP) is the first step and one of the key technologies to realize autonomous robot welding. The purpose of this paper is to describe a method developed to accomplish successful autonomous detection and guiding of SWP. Design/methodology/approach – The images of workpieces are snapped by charge coupled device (CCD) cameras in a...
