Research Abstract

The aim of this study is measure the 3D temperature distribution of axially asymmetrical welding arc plasma. This requires spectroscopic method, multidirectional measurement and tomographic technique with image reconstruction. First, we employed the optical rotational system by one CCD camera and improved the equipment through the evaluation of the appropriate detection directions and numbers. Two TIG electrode arc was measured by this system. Second, we constructed the simultaneous and multidirectional measurement system was constructed to measure the axially asymmetric and non-steady state plasma. To ensure the correct measurement using multi detectors and the interference filters, the calibrations were conducted involving the adjustment of the central wavelength through the filter. We could perform the temperature measurement of the transient and asymmetrical TIG arc plasma such as in the transition period between the peak and base current of the pulsed TIG arc with tilted torch.
