Secondary fusing leads to gas leakage, can only carry out leak stopping by multiple repair welding after welding, product quality is poor.And it is based on existing structure, hand
Weld seam can not be directly heated and be observed at the multiple steps being affected to electrical specifications when work flame welding, solder dissolve and pricker
Material heap product situation is difficult to observe.Simultaneously because two waveguide bend weld seams are up to 225mm, postwelding end stress concentration is serious, later stage dress
Timing easily causes waveguide bend end to be snapped.
2. the bulk between liang waveguide mouth only leans on end cavity in connection to ensure have between two waveguide bends super
The hanging of 200mm is crossed, post welding distortion is big, two waveguide mouth central space distances 25.05 0.1 of drawing requirement, 75 ° of space angle
± 10 ' extremely difficult guarantees, can only be by postwelding school shape, but school shape process easily leads to weld cracking.
3. step piece cavity is the vital part for influencing transmitting-receiving feed insertion loss, step piece thickness only 1mm therein, warp
After crossing processing and welding, the deformation of step piece is serious, it is difficult to ensure that symmetry ± 0.05mm.
4. the deeply narrow chamber of cavity part and step cavity configuration feature in cavity coupler are at present external coordination electrical discharge machining, add
Work efficiency rate is low, of high cost, and part process cycle is long, restricts model batch production progress.
