STUDY ON FRONT SIDE ARC LIGHT SENSING IN KEYHOLE MODE PLASMA ARC WELDING

Abstract

Abstract: The maintenance of a stable keyhole during PAW welding process is of critical importance and the ultimate quality of the weld and the process stability depend strongly on the keyhole stability. A compact arc light sensor is developed based on the spectroscopic study on the plasma arc. By using this sensor, information concerning the keyhole formation and keyhole collapse could been extracted. The makeup of the arc light sensor, physical model of arc light sending and signal characteristics, are discussed.

Key words: Arc light, Keyhole, PAW, Sensor, Design, Design thinking, Innovation, Innovation method, Innovative design
