A study on the seam tracking in CO_2$ fillet welding by using an arc sensor
CO_2$ 용접에서 전기적인 아크신호를 이용한 수평 필릿 용접선 추적에 관한 연구
Abstract
The harsh nature of welding environments makes welding a prime candidate for process automation. Among the variety of welding processes available, gas metal arc welding is one of the most frequently used methods, primarily because it is highly suited to a wide range of applications, and also to automation. Automatic seam tracking method is one of the most demanded techniques for automatic control of arc welding. In this study a seam tracking system has been developed by using the welding arc itself as a sensor. This paper described the principle and experimental result of the arc sensor system, as well as the development and application of the automatic
