| Abstract: |
| The gap control technology is an important technology to ensure the vacuum brazing quality of the slotted waveguide array antenna. By studying the method of controlling the deformation of parts and dimension stability, ultra poor parts of the form and position tolerance can be improved, and 95% parts can meet the brazing requirement. Through the control of the assembly surface roughness, deformation control, and welding jig technology, the assembly clearance of the site can be compensated, and the gap requirements of vacuum brazing can be ensured. The quality of welding can be improved, the antenna pass rate after brazing is close to 100%. |
