The arc atmosphere of stainless steel flux-cored wire is difficult to be detected online. Therefore, a digital fiber optic spectrometer has been applied to collect the arc spectrum of stainless steel flux-cored wires with different welding parameters. The spectrum collected was comparatively analyzed and used to identify the arc atmosphere element it implied. Furthermore, the characteristics of welding process and varying pattern of radiation were studied. This method can effectively detect the element in arc atmosphere and has provided theoretical and experimental basis for detecting the welding arc atmosphere of stainless steel flux-cored wires.
