Due to violent disturbance of the welding arc, signal processing is the key problem of ap-plication of the sensor. By means of the new technique the arc sensor can recognize not only V-groove but also lap joint and butt joint. The sensor has good recognition ability even for welding process with very large current disturbance, e.g. pulsed arc and short circuit welding process, etc. The proposed technique is developed on the basis of modern digital filtering theory and mathematic transformation of the signals from time domain into frequency domain.

The Influence of all variables, such as materials of a measured object, condition of its surface, distance, and shut off time m the measurement of temperature field by colorimetric method with ICCD as sensor, is analyzed theoretically and studied by experiments. The obtained results prove the feasibility and reliability of the developed method.

The real-time measurement of welding temperature field by colorimetric method is described, and with the data acquired from it closed-loop control system of the parameters of temperature field is developed and tested. Ex-perimental results prove that it has high measurement speed (time of a field within 0.5s) and good dynamic response quality. Weld penetration can be controlled satisfactorily under unstable welding condition.

【期刊论文】Arc sensing system for automatic weld seam tracking (I)-Mathematic model

Arc sensor, one of the most popular and effective sensors for automatic seam tracking of arc welding, is systematically studied. A mathematic model of the static and the dynamic properties of the sensor derived on the basis of control theory and experimental method are described. The model extends our understanding of arc sensor from qualitative level to quantitative level. This is important for its design and further development.
