文摘Pseudo color measuring of the infrared radiation from molten pool is used to gather information on the seam position and on the welding penetration. Characteristics are detected using color sensing devices. Test results from both thermal simulation and robotic arc welding are regular and reproducible. The pseudo color values were found to be directly relative to the seam position and welding penetration, therefore, they could be used for monitoring welding penetration and for seam tracking.
