Intelligent robotic welding is a trend in the development of welding manufacturing and has a great application prospective. Weld pool dynamics plays a vital role in assuring the production of high-quality welds. Precision measurement of the weld pool surface characteristics is a bottleneck for accurate control of weld penetration as well as for successful development of next-generation intelligent welding system. In this article, the current progress in arc welding pool sensing is detailed and challenges in weld pool measurement analyzed. The key factor that hinders the development of intelligent robotic welding systems is identified and the approaches that realize the intelligent welding are also discussed. Lastly, the trend of intelligent welding manufacturing is predicted.
