[0053]Contraction belowFigure 1-2Further detailed description of the present application.
[0054]The present application discloses a fan welding process, and the process steps of the fan welding process are as follows:
[0055]S1, the housing is welded:
[0056]S11, welding processes: Clean up the welding position of the upper casing and the lower case by the high pressure nozzle;
[0057]S12, the upper housing and the lower housing are positioned: the upper casing and the lower housing are limited by the welding tool, the upper casing and the lower housing are made, so that the upper casing and the lower housing are positive, and then the pin is passed Perform a preliminary positioning, and then weld the upper casing and the lower housing;
[0058]S13, the weld position of the upper housing and the lower housing is preheated, and the temperature of the preheating to the weld position of the upper casing and the lower housing is 80-150 ° C;
[0059]S14, then segment the upper casing and the lower ho...
