Welding using Advanced Robotics

The Robotic welding has been able to replace physical welding in hostile conditions with extreme temperature and gas vapors because now sensor-based features are available for controlling the robots in welding processes which is a great tech. advancement. The industrial robots are mainly used in the GMAW which gas metal arc welding and in high-capacity productions. Greater capability to manage welding settings and robotic movements, as well as enhanced problem identification and repair, have been necessary as robotic welding has become more widely used. The requirement to adjust for imperfections in work piece fixtures, fluctuations in dimensions of work piece, improper preparation of edge, and thermal distortions etc. issues that semi-automatic robotic welding (needing very minimum human interaction) encounters. Seam tracking and detection of edge of joint, controlling penetration of weld and measuring joint dimensions are some major issues. To tackle these challenges the best way is to use the sensors and take the feedback signals from the weld joint .Therefore, from evaluating underway weld quality, variation in shape & position of joint to tracking of joint, sensors play a vital role . This paper discusses robotic welding in general, robotic welding system programming, and robotic welding difficulties. This research expands knowledge of robotic welding, the importance of sensors in the welding process by the robots, and the issues that come with it.
