Abstract

Abstract:

The welding deformation of 20 sectors in the vacuum chamber of HL-2M tokamak and the precision control of the ring forming dimension are realized by combining the group welding platform with a large numerical control machine tool. High vacuum helium leak detection was carried out on the weld seam of the vacuum chamber after the ring was formed. The size, shape and position accuracy of the vacuum chamber were detected by large numerical control machine tool combined with theodolite, and the results met the design requirements.

Key words: HL-2M tokamak, Vacuum chamber, Ring formation process, Group welding platform
