Survey of Robotic Seam Tracking Systems for Arc Welding

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...

Robotic Shielded Metal Arc Welding

In this work, the development and validation of a methodology for robotic welding with covered electrodes (SMAW) using a variation of the tool center point (TCP) model is shown. The covered electrode becomes part of the kinematic model of the robot as an additional prismatic joint, whose movement is determined by the electrode consumption or melting rate. This allows programming the trajectory ...

Design and validation of a universal 6D seam-tracking system in robotic welding using arc sensing

This paper presents the design and validation of a novel and universal 6D seam tracking system that reduces the need of accurate robot trajectory programming and geometrical databases in robotic arc welding. Such sensor driven motion control together with adaptive control of the welding process is the foundation for increased flexibility and autonomous behavior of robotic and manufacturing syst...

A flexible seam detection technique for robotic laser welding

This thesis deals with the problem of seam detection for robotic laser welding applications. Within the Mechanical Automation laboratory of the Engineering Technology faculty, a compact, lightweight and multi-purpose welding head is developed. The integrated welding head is attached to a robot and should be able to detect seams, learn trajectories, do the laser welding and inspect the welds. A ...
