Spot welding inzira inoshandiswa zvakanyanya yekujoinha mumaindasitiri ekugadzira, anosanganisira emota uye aerospace sector.Mune yepakati frequency inverter welding michina, kuramba kwenzvimbo welding kunoita basa rakakura mukuona kunaka uye kuvimbika kweiyo weld.Ichi chinyorwa chinoongorora kushorwa kunobatanidzwa mukuwodhesa nzvimbo uye kukosha kwayo mukuwana akabudirira welds.
Tsanangudzo yeresistance in spot welding:
Resistance in spot welding inoreva kushorwa kunowanikwa nemagetsi emagetsi paanopfuura nepakati pezvishandiso zviri kubatanidzwa.Kupokana kunokonzerwa nezvinhu zvakasiyana-siyana, zvinosanganisira zvinhu zvemukati, mamiriro ekunze, dhizaini ye electrode, uye kusangana kwekupokana pakati pema electrode uye workpieces.
Zvinhu zvinokanganisa kuramba mu spot welding:
Material zvivakwa: Zvishandiso zvakasiyana zvinoratidzira zvakasiyana-siyana zvemagetsi, izvo zvinokanganisa kuramba kwavo kuyerera kwemagetsi ikozvino panguva yewelding.Zvishandiso zvine yakakwirira yemagetsi resistivity, senge simbi isina simbi, kazhinji zvine kukwirira kwepamusoro kana zvichienzaniswa nezvinhu zvakaita semhangura kana aluminium.
Mamiriro epamusoro: Hutsanana uye mamiriro epamusoro ezvishandiso zvinokanganisa zvakanyanya kubatwa kwemagetsi uye, nekudaro, kuramba panguva yewelding.Oxidation, machira, kana zvinosvibisa pane workpiece nzvimbo zvinogona kuwedzera kuramba uye kutadzisa kuumbwa kwesimba weld.
Electrode dhizaini: Dhizaini uye chimiro chema electrode zvinopesvedzera nzvimbo yekubata uye kudzvanywa kunoiswa kune workpieces.Yakakodzera electrode dhizaini inovimbisa kushanda kwazvino kuchinjisa uye inoderedza kushorwa pane electrode-workpiece interface.
Bata kuramba: Iko kusangana kwekupokana pakati pe electrode uye workpieces kunokanganisa kupikisa kwese kweiyo nzvimbo welding process.Izvo zvakakosha kumisikidza yakanaka yemagetsi kusangana pakati pee electrode uye workpieces kuderedza kuramba uye kufambisa inoshanda ikozvino kuyerera.
Kukosha kwekudzora kuramba mune spot welding:
Kudzora kupokana munzvimbo welding kwakakosha kuti uwane anowirirana uye emhando yepamusoro welds.Kupokana kunobata zvakananga chizvarwa chekupisa, nugget kugadzirwa, uye yakazara weld simba.Optimal kuramba inovimbisa yakakwana kupisa kupinza kunyungudutsa workpiece nzvimbo uye kugadzira yakasimba metallurgical bond.Kutsauka mukupikisa kunogona kukonzera kusakwana kwe weld fusion, majoini asina simba, kana kukuvara kwe electrode.
Mune yepakati frequency inverter welding michina, kupokana kunobatanidzwa mune nzvimbo welding kunoita basa rakakura mukuita welding.Kunzwisisa zvinhu zvinopesvedzera kuramba uye kudzora mukati meiyo yaunoda chiyero kwakakosha pakugadzira akavimbika uye anogara akasimba spot welds.Nekukwenenzvera kusarudzwa kwezvinhu, kuchengetedza nzvimbo dzakachena dzebasa, kugadzira maelectrode akakodzera, uye nekuona kwakaringana electrode-kune-workpiece kuonana, vashandisi vanogona kunyatso kubata kuramba uye kuwana akabudirira nzvimbo welds nemhando yaunoda uye kuita.
