Abstract: The first wall for the HL-2M first plasmas is mainly composed of 2mm thick guard plates and 
affiliated supports, which together with the limiters form the protection layer for inner wall of HL-2M vacuum 
vessel. According to the structural design of the first wall and the overall installation specifications of HL-2M 
tokamak, the overall installation process plan of the first wall was proposed. The supports of the first wall were 
fixed by stud welding and argon arc welding. The assistant tools that can adjust the positioning accuracy of the 
parts by the use of studs were applied, and the laser tracker is used to adjust the installation accuracy in real time 
throughout the process. Finally, the overall installation of the first wall of the HL-2M initial plasma is completed. 
The component installation accuracy reaches ±2mm, the weld quality meets the requirements of the first level 
weld, and the structure can withstand a tensile force of more than 3675N.The first wall works well during the 
HL-2M first plasma discharges.
