[0002] Microwave components are often used to transmit microwave signals in closed environments, such as communication equipment, radar systems, etc. In these applications, the requirements for airtightness are very high, because even a small gas leak may cause signal loss or equipment performance degradation. In order to ensure the stability of the gas environment inside the microwave component, it will be hermetically sealed and welded during the production process.

[0003] When performing airtight welding of microwave components, first place the microwave components directly on the welding seat, and limit the microwave components through the welding seat to ensure that the position of the device is accurate and stable. Then start the welding head, move it to the welding position, and apply appropriate heat and pressure through the welding head to weld the two components together, so as to achieve airtight welding;

[0004] However, during the welding process, since the welding equipment is exposed, it is difficult to ensure the welding environment. As a result, impurities in the external environment are easy to fall on the surface of the microwave component during the welding process, resulting in uneven heating of the welding area due to surface impurities during the airtight welding process, resulting in poor airtightness at the weld.
