Embodiment Construction
[0019] see Figure 1 ~ Figure 3 . In the following embodiments, only the mounting plate with an eccentric annular seam is used as the component to be welded, and this embodiment is used to further illustrate the present invention, and these embodiments are only used to illustrate the present invention without limiting the present invention. The mounting plate is mainly composed of a mounting seat 1 and a sealed oil inlet nozzle 2 to be welded, a sealed air inlet nozzle 3 , a sealed air outlet nozzle 4 , and a sealed oil outlet nozzle 5 distributed around the central axis of the installation seat 1 . Sealed oil inlet nozzle 2, sealed air inlet nozzle 3, sealed air outlet nozzle 4, and sealed oil outlet nozzle 5 are all parts to be welded with eccentric annular seams, and they are divided into electron beam welding I, II, III, and IV.
