Yakadzama Ongororo Yemhando Yekutarisa Tekinoroji dzeWelded Joints muMedium-Frequency Inverter Spot Welding Machines.

Hunhu hwemajoini akakwenenzverwa anogadzirwa nepakati-frequency inverter spot welding michina yakakosha pakuona kutendeseka uye kuita kwezvakasiyana zvigadzirwa. Kuti uwane anowirirana uye anovimbika welds, zvakakosha kuti tiite anoshanda emhando yekutarisa maitiro. Ichi chinyorwa chinopa tarisiro yakazara yemaitiro ekutarisa anoshandiswa kuongorora kunaka kwemajoini akaiswa mukati mepakati-frequency inverter spot welding michina.

1. Kuongorora Kwekuona: Kuongorora kwekuona inzira yakakosha yekuongorora kunaka kwemajoini akasungwa. Vashandi vanotarisa nzvimbo yeweld kuti vaone kukanganisa kwakajairika senge isina kukwana fusion, yakawandisa spatter, kutsemuka, kana kuumbwa kwakashata nugget. Ongororo yekuona inogona kuitwa uchishandisa maturusi ekukudza, senge microscopes kana borescopes, kuwedzera kuongororwa kweakaomesesa kana akaoma-kusvika-kusvika-welds.
2. Nzira dzisiri dzekuparadza dzekuedza (NDT): Nzira dzisiri dzekuparadza dzekuyedza dzinoita basa rakakosha mukuongorora kuvimbika kwemukati uye pamusoro pemajoini akasungwa pasina kukuvadza. Mamwe anowanzo shandiswa NDT matekiniki ekutarisisa kunaka mune yepakati-frequency inverter spot welding michina inosanganisira:

• Ultrasonic Testing (UT): UT inoshandisa mafungu e-high-frequency sound waves kuti aone kukanganisa kwemukati sekushayikwa kwe fusion, porosity, kana kuputika mujoini yakasungirirwa. Mafungu anoratidzwa anoongororwa kuti aone kukura, chimiro, uye nzvimbo yezvakaremara.
• Radiographic Testing (RT): RT inosanganisira kushandiswa kweX-rays kana gamma rays kugadzira mifananidzo yejoini yakasungwa. Inogonesa kuonekwa kwekuremara kwemukati, zvakadai se inclusions, voids, kana kukanganisa. Radiographic mifananidzo inogona kupa ruzivo rwakadzama nezve weld mhando uye kutendeseka.
• Magnetic Particle Testing (MT): MT inonyanya kushandiswa kune ferromagnetic zvinhu. Maitiro acho anosanganisira kushandiswa kwemagineti uye kushandiswa kwemagineti particles. Chero kukanganisa-kupwanya kwepamusoro, zvakadai sekutsemuka kana kuputika, kunokanganisa magnetic field, zvichiita kuti zvimedu zviungane panzvimbo dzakakanganisika uye zvionekwe.
• Dye Penetrant Testing (PT): PT inokodzera kuona kuremara kwepamusoro mune zvisiri-porous zvinhu. Nzira yacho inosanganisira kuisa dhayi ine ruvara pamusoro, ichibvumira kuti ipinde chero ipi zvayo yakakanganiswa. Dhayi yakawandisa inobviswa, uye mugadziri anoiswa kuti awedzere kuoneka kwehurema.

3. Mechanical Testing: Mechanical yekuyedza nzira dzinoshandiswa kuongorora ma mechanic zvivakwa uye kusimba kwemajoini akasungwa. Mamwe maitiro akajairika anosanganisira:

• Tensile Testing: Tensile kuyedzwa kunosanganisira kuisa simba rekumanikidza kujoinhi yakasungwa kusvika yatyoka. Muedzo uyu unobatsira kuona kwekupedzisira kusimba kwejoinhi, kusimba kwegoho, uye kurebesa, ichipa manzwisisiro mukuperera kwayo kwemichina.
• Kuomarara Kuyedzwa: Kuomarara kuyedzwa kunoyera kuoma kwejoint yakasungwa uchishandisa midziyo yakasarudzika, yakadai seyekuomarara. Inopa chiratidzo chesimba rejojo ​​uye kurwisa deformation.

4. In-Process Monitoring: In-process monitoring techniques inobvumira nguva chaiyo-yekuongorora ye welding parameters uye zviratidzo zvehutano panguva yekushanda kwewelding. Matekinoroji aya anowanzo sanganisira kushandiswa kwemasensa kana masisitimu ekutarisa kutora uye kuongorora data rine chekuita neazvino, voltage, tembiricha, kana simba. Kutsauka kubva pazvikumbaridzo zvakatarwa kana zvakafanotsanangurwa zvinogona kukonzeresa chenjedzo kana otomatiki gadziriso kuchengetedza inowirirana weld mhando.

Maitiro ekutarisa emhando anoshanda akakosha pakuona kuvimbika uye kushanda kwemajoini akaiswa anogadzirwa nepakati-frequency inverter spot welding michina. Nekubatanidza kuongorora kwekuona, nzira dzisiri dzekuparadza dzekuyedza, bvunzo dzemakanika, uye mukati-maitiro ekutarisa, vagadziri vanogona kunyatso ongorora mhando yewelds. Aya matekiniki anogonesa kuona nekukurumidza kwehurema, kuve nechokwadi chekuti zviito zvekugadzirisa zvinogona kutorwa nekukurumidza kuchengetedza emhando yepamusoro welds uye kusangana nezvinodiwa zvinodiwa. Kuita akasimba emhando yekutarisa matekiniki anosimudzira kugona kwese uye kushanda kwepakati-frequency inverter spot welding michina, inotungamira.
