Iyo yekusiyanisa maitiro ekupikisa munzvimbo yewelding panguva yekuitamedium frequency spot weldinginyaya yakakosha yedzidziso muresistance welding. Mushure memakore ekutsvagisa, maitiro ekusiyana kweakasiyana-siyana anopokana mukupokana welding munzvimbo dzinotonhora uye dzinopisa akatemerwa, pamwe nehukama hwavo nezvinhu zvakaita semamiriro ekunze, simba remagetsi, welding ikozvino, nezvimwe.
Izvo zvakasimbiswa zvakare kuti dynamic kuramba, iyo inofunga voltage uye zvazvino zvinhu, ine hukama hwepedyo nehukuru hweiyo fusion musimboti. Iyo yakapusa voltage yekutarisa nzira inogona kuratidza zvirinani mamiriro efusion musimboti kukura. Kwemakore makumi maviri apfuura, vanhu vakashandisa dzidziso yakakosha iyi, kunyanya hukama huripo pakati pekupokana uye fusion core chizvarwa, kugadzira tekinoroji yekutarisa welding, ichiva nzira inoshanda yekutarisisa kunaka kwenzvimbo. Parizvino, dynamic resistance monitoring masisitimu ave achishandiswa zvakanyanya mukugadzira mukati mekunze nekunze.
Nheyo yeDynamic Resistance:
The resistance change curve (kureva, dynamic resistance curve) inogona kuwanikwa kuburikidza nezviyedzo. Kana zvinhu zvesimbi zvakaiswa mavara, hunhu hwavo hwekupikisa curve hunogona kucherechedzwa.
Muinjiniya tekinoroji, hunhu hwepakarepo hunogona kurapwa nenzira inotevera: kutora welding ikozvino sechikamu chehafu-kutenderera, izvo zvinosiyana mukati mehafu yekutenderera zvinoonekwa sezvinogara. Kana kuti, humwe hunhu hunokosha hwezvakasiyana-siyana mukati mehafu yekutenderera hunotorwa. Nokudaro, peak voltage pakati pema electrode maviri inotsanangurwa seyakakosha ikozvino inobudirira mukati mehafu yenguva, uye kushorwa kunosvika kana kukwirira kunowanikwa kunotsanangurwa sekupikisa mukati mehafu yenguva. Iyi tsananguro inonyatso bvisa pesvedzero yemamwe magineti emagetsi nekutora peak voltage uye inosanganisira iyo inopisa chinhu nekutora iyo inoshanda yazvino kukosha. Nekudaro, pane hukama hwepedyo pakati pekupokana kwesimba uye fusion core size.
Zvinoenderana neakambotaurwa ekupikisa curve, hunhu hwayo ndehwekuti pakutanga kwenzvimbo welding, kupokana kunokurumidza kuderera sezvo kushomeka kwekubata kunopera. Zvadaro, kupikisa kunoramba kusingashanduki, kuumba mutsara wakatsetseka. Ichi chikamu chekupikisa curve hachichinji nekusiyana kwehukuru hwefusion core. Naizvozvo, zvinhu zvine hunhu hwakadaro curves hazvina kukodzera kushandisa nzira dzemagetsi ekutarisa kuona kunaka kwewelds. Monitoring spot welding quality zvichienderana nehunhu hwemhando yekutanga ye dynamic resistance curve inonyanya kutora mafomu maviri: tracking resistance curve method uye kuramba shanduko kana kuramba shanduko rate nzira.
Iyo yekutevera yekudzivirira curve nzira inoshandisa microprocessors uye peripheral maseketi kutanga kuchengetedza ane simba ekupikisa macurves eanokwanisa welds kana hukama hwekuita basa hunotarwa kuburikidza nekuyedza. Zvino, kune yega yega weld uye yega yega hafu kutenderera kwakazobatanidzwa, iyo welding ikozvino inoverengerwa uye kugadziridzwa kuti imanikidzire kusimba kweiyo weld mukuita kuumbwa kutevedzera dynamic kuramba curve yeanokwanisa welds kana akatsunga kuramba basa hukama, nekudaro. kuve nechokwadi chemhando yeweld yega yega.
Iyi nzira inoda kugashirwa kwewelding ikozvino uye peak voltage pakati pemagetsi ega ega hafu kutenderera, uye kukosha kwekupokana kweiyo hafu kutenderera kunofanirwa kuverengerwa. Inofanirawo kuenzaniswa neyakachengetwa dynamic curve. Kana kutsauka kunoitika, iyo welding ikozvino inofanirwa kugadziridzwa mune inotevera hafu kutenderera kuti ive nechokwadi chekuti kushorwa kweiyo weld kunogara kuchitevera dynamic resistance curve yeanokwanisa welds. Iyi nzira inonetsa, asi nekukurumidza uye kwakaringana kugona kwekuverenga komputa kana microprocessors, otomatiki kutonga kunogona kuwanikwa.
