Abstract

The invention discloses a method and a device of measuring welding electric arc spectrum spatial information. Based on a pore imaging theory, an inverted and amplifying real image is formed by a pore,a spectrometer probe is critically controlled by a two-dimensional mobile device and gather in an amplifying real image spatial space in real time, and the welding electric arc spectrum spatial information of characteristic spectral lines with different position and different wave length are obtained in the electric arc spatial area and used for judging electric arc physical information about electric arc spatial particle species and distribution analysis. According to the method and the system of measuring the welding electric arc spectrum spatial information, precise and real-time measurement of the spectrum information in the welding electric arc space is conducted in the welding process.

Description

technical field [0001] The invention relates to the technical field of welding arc spectrum information measurement, in particular to a method and device for measuring welding arc spectrum spatial information. Background technique [0002] In the welding process, in order to obtain a satisfactory welded joint and ensure the connection quality of the weldment, the physical analysis of the welding arc has always been the research direction of many scholars. Among them, the arc spectral space information contains a large amount of arc physical information, so the measurement of the spectral space information It is also an important part, and the current commonly used arc airspace measurement methods are: the light screen behind the convex lens is connected. The arc spectrum information collection method of this method is to build an optical path so that the arc light passes through a convex lens to form a magnified real image, then use a light screen to receive and present the ...
