Abstract

The invention discloses a method for processing a seam of an accelerating tube. By using the method, the seam of the accelerating tube can be processed effectively, and metallic vapor contaminants attached to the outer surface of a porcelain ring are effectively cleared. The method comprises the following steps: (1) carrying out manual amendment on the seam of the accelerating tube; and (2) putting the accelerating tube in a closed sandblasting chamber of a sandblasting machine for sandblasting.

Description

technical field [0001] The invention relates to a welding seam processing method, in particular to an accelerated pipe welding seam processing method. Background technique [0002] The ceramic rings and electrode sheets of the high-voltage accelerating tube in the electron accelerator are stacked and assembled at intervals. After arranging circular ring sheet solder between the two ends of each accelerating tube ceramic ring and the corresponding electrode sheet, put it into the accelerating tube welding furnace to heat to melt the solder, so as to connect the ceramic ring and the electrode sheet. Under the above-mentioned conditions of vacuum and protective atmosphere, the weld seam after brazing will overflow, and there is a layer of metal vapor pollutants on the outer surface of the ceramic ring, which will affect the physical properties of the ceramic ring, such as voltage resistance. Deterioration, the phenomenon of creepage on the surface of the object, etc. Content...
