Abstract

Abstract: The magnetic permeability of HL-2M support system was controlled within the design value, i.e.
≤1.03, when the special nitrogen control stainless steel was adopted, the GMS310 welding wire and Ar (96%) +
N2 (4%) shielding gas were employed in welding, and the scheme of low speed and large feed rate in machining
process was performed. In order to ensure the precise positioning of the coil system during assembly, it was
necessary to preinstall the poloidal field coils support subsystem in development stage.

Key words: HL-2M tokamak, Support components, Welding magnetic permeability, Preassembly
