Automatic Real-Time Bead Height Control with Arc Sensor in TIG Welding

概要

論文の詳細を見る
Arc sensor, which utilizes the welding arc as a sensor, gives important groove information during welding. The automatic seam tracking control system with an arc sensor developed by NKK has a feature in that the turning point of transverse weaving with constant arc length control (AVC) is decided by the condition when torch height reaches a constant set level. Applying the above control system, variations of groove and deposition area can be detected from the trace of weaving. An automatic real-time bead height control system has been developed utilizing the above detected information. The area and width of weaving trace have close correlation with the areas of groove and deposition. Experiments conducted with varied groove width proved satisfactory control ability of the system for all-position TIG welding.
