Abstract

The invention relates to the technical field of submerged-arc welding, in particular to a submerged-arc welding droplet collection and arc plasma characterization device and method.The submerged-arc welding droplet collection and arc plasma characterization device comprises a translation mechanism, a cooling component, a metal conductive component and a plurality of spectral signal guiding components, and the cooling component is arranged on the translation mechanism; the metal conductive member is arranged on the cooling member; the plurality of spectral signal guiding components are arranged on the metal conductive component and are sequentially arranged at intervals along the length direction of the metal conductive component; the spectral signal guide member is formed with a conduction channel. By means of the device, submerged arc welding molten drops can be collected, and due to the fact that the molten drops are rapidly cooled, the collected molten drops are in a non-equilibrium state, and part of the characteristics of the molten drops in an electric arc cavity can be reserved. By utilizing the synergistic effect of the spectral signal guide component, the translation mechanism and the spectrometer, the plasma spectral information in the arc cavity can be stably collected in multiple sections, and the in-situ spectral analysis of the plasma is realized.

Description

technical field [0001] The present application relates to the technical field of submerged arc welding, in particular to a device and method for collecting droplet and characterizing arc plasma in submerged arc welding. Background technique [0002] At present, with the rapid development of my country's shipbuilding industry, it poses challenges to the shipbuilding cycle and hull tonnage. Submerged arc welding is a (semi) automatic arc welding method that covers the arc under the welding machine particles and slag. It has the characteristics of high deposition efficiency, good weld metal formability and strong welding stability, and is widely used in important manufacturing fields such as ships and offshore pressure vessels. In submerged arc welding, flux plays the roles of stabilizing the arc, creating slag, controlling the forming of weld metal and isolating air. Due to the intense chemical reaction among the flux, the molten pool and the arc cavity, and the plasma materia...
