Background
The waveguide is generally formed by filling a hollow metal tube with a medium, the surface of which is generally a continuous single surface, and the hollow metal tube with different cross-sectional shapes is called the waveguide because the hollow metal tube limits and guides electromagnetic waves therein.

According to the thought, various waveguide components with large loss are cut by linear cutting, and the phenomenon of solder overflow at the soldered joint is found; step burrs are found at the joint of some parts; poor roughness of the inner surface of the elbow joint and the like. The existence of the phenomenon is equivalent to poor surface roughness quality of the inner cavity of the waveguide, and is one of main reasons for influencing microwave transmission loss.
