Spot welding inzira inoshandiswa zvakanyanya muindasitiri yekugadzira, inozivikanwa nekushanda kwayo uye nekukasira mukujoinha simbi workpieces.Nekudaro, welding workpieces yekusaenzana ukobvu uye zvakasiyana zvinhu zvinogona kuve basa rakaoma.Muchinyorwa chino, isu tichaongorora matekiniki uye kufunga kwekunyatsoona welding maworkpieces akadaro.
1. Kusarudzwa kwezvinhu:
Usati wanyura mune welding process, zvakakosha kuti usarudze akakodzera welding maelectrodes uye marongero emidziyo iri kubatanidzwa.Masimbi akasiyana ane akasiyana conductivity uye kupisa dissipation zvivakwa, izvo zvinogona kukanganisa kunaka kweweld.Semuenzaniso, kana uri welding simbi kune aruminiyamu, iwe unozoda ehunyanzvi maelectrode akagadzirirwa zvakasiyana-siyana welding.
2. Welding Parameters:
Iwo akakosha maparamendi enzvimbo welding ndeye welding ikozvino, welding nguva, uye electrode simba.Aya ma parameter anofanirwa kugadziridzwa zvichienderana nehupamhi hwezvinhu uye rudzi.Zvishongo zvakakora zvinowanzoda akakwira welding current uye nguva refu dzewelding.Kune zvinhu zvakasiyana-siyana, kuwana chiyero chakakodzera kwakakosha kuti udzivise kuwandisa-welding kana pasi-welding.
3. Electrode Design:
Tsika electrode dhizaini inogona kubatsira kugovera welding simba zvakaenzana pazvishandiso zvebasa, kunyangwe paine ukobvu hwakasiyana.Semuenzaniso, electrode yakatsikwa ine dhayamita yakakura kune rimwe divi inogona kushandiswa kuve nechokwadi cheiyo weld pane yakakora zvinhu uchidzivirira kutsva-kuburikidza pane iyo yakatetepa.
4. Tack Welding:
Tack welding inosanganisira kugadzira diki, preliminary welds panzvimbo dzakarongwa padyo nejoint kubata kwechinguva maworkpieces pamwechete.Izvi zvinogona kunyanya kubatsira kana uchibata nezvinhu zvehukobvu hwakasiyana.Tack welds inova nechokwadi chekuti maworkpiece anogara akabatana panguva yekupedzisira welding process.
5. Welding Sequence:
Kutevedzana kwaunopinza zvinhu zvakasiyana kunogona kukanganisa kunaka kwejoint.Zvinowanzo kurudzirwa kuti utange nezvinhu zvakatetepa wozoenda kune yakakora.Izvi zvinodzivirira kuwanda kwekupisa mukati mezvinhu zvitete, izvo zvinogona kutungamirira mukupisa-kuburikidza kana kukanganisa.
6. Kuedza uye Kuongorora:
Mushure mekupedza weld, zvakakosha kuti uongorore kubatanidzwa kwemhando.Dzakasiyana-siyana dzisiri dzekuparadza nzira dzekuyedza, dzakadai sekutarisa kwekuona, dhayi inopinda mukati, kana X-ray kuongororwa, inogona kushandiswa kuve nechokwadi chekuvimbika kweweld.
7. Kudzidzira uye Kudzidzisa:
Welding zvinhu zvakasiyana-siyana uye workpieces yehukobvu husina kuenzana inogona kuve hunyanzvi hwakaoma.Kudzidziswa kwakakwana uye kudzidzira kwakakosha kuti mawelder agadzirise hunyanzvi hunodiwa kuti nguva dzose vagadzire majoini emhando yepamusoro mumamiriro akadai.
Mukupedzisa, welding workpieces yehukobvu husina kuenzana uye zvinhu zvakasiyana zvine mushini wekugadzira welding zvinoda kunyatsotariswa kwezvinhu, welding paramita, electrode dhizaini, uye welding sequence.Nekutevera iyi nhungamiro uye nekudyara mumidziyo yakakodzera, vagadziri vanogona kuwana yakasimba uye yakavimbika welds mumhando dzakasiyana dzekushandisa, kunyangwe kana vakatarisana nezvinonetsa zvinhu musanganiswa.
