Resistance spot welding inzira inoshandiswa zvakanyanya yekujoinha mumaindasitiri akasiyana siyana, kunyanya mukugadzira mota neaerospace. Iyi nzira inosanganisira kushandisa magetsi emagetsi uye kumanikidza kugadzira zvisungo zvakasimba pakati pemashizha esimbi kana zvikamu. Chimwe chinhu chakakosha chinowanzo mutsa mibvunzo ibasa rezvino uye voltage mukuona kunaka uye kushanda kwenzvimbo welds. Muchinyorwa chino, isu tichaongorora maitiro ezvino uye voltage marongero pane resistance spot welding.
Kunzwisisa Resistance Spot Welding
Usati wanyura musimba rezvino uye voltage, zvakakosha kuti ubate izvo zvekutanga zveresistance spot welding. Mukuita uku, nzvimbo mbiri dzesimbi dzinounzwa mukusangana uye dzinoiswa kune yakakwira magetsi ikozvino. Iyi ikozvino inoyerera kuburikidza nesimbi uye inogadzira kupisa nekuda kwekudzivirira kwayo. Kupisa kunonyungudutsa chikamu chidiki chesimbi, zvichiita kuti nugget yakanyungudutswa inotonhodza nekuoma kuita weld.
Basa Rezvino
Ikozvino kuseta mukupikisa nzvimbo welding inoita basa rakakosha pakuona kunaka kweiyo weld. Inobata mwero wekudziya, saizi ye nugget, uye simba rose rebhondi. Heino maitiro:
- Mwero wekupisa:Mazinga epamusoro azvino anotungamira kukurumidza kupisa mwero. Izvi zvinogona kubatsira kune zvinhu zvitete nekuti zvinoderedza kupisa uye zvinokonzeresa nzvimbo diki-inokanganiswa nekupisa. Nekudaro, kune zvakakora zvinhu, yakawandisa ikozvino inogona kukonzera kupisa-kuburikidza kana spatter.
- Nugget size:Izvozvi zvinopesvedzera saizi yeakanyungudutswa nugget yakaumbwa panguva yewelding. Mazinga epamusoro emazuva ano anowanzo kugadzira nuggets hombe. Iyo nugget saizi yakakosha nekuti inobata zvakananga kusimba kwejoinhi. Kusakwana ikozvino kunogona kutungamira kune isina simba, undersized nuggets, kukanganisa kuvimbika kwe weld.
- Bond Simba:Unhu hwe weld hwakanyatsobatanidzwa kune ikozvino. Kunyatsogadziriswa mazinga azvino anovimbisa yakasimba uye yakasimba weld. Kutsauka kubva kune yakakurudzirwa ikozvino mutsara kunogona kutungamirira kune isina simba zvisungo uye kuderedzwa kwemaitiro kutendeseka.
Basa reVoltage
Voltage, yakabatana neyazvino, inoita basa rinotsigira mukupikisa nzvimbo welding:
- Arc Initiation:Voltage ine basa rekutanga arc pakati pe electrode uye workpiece. Inoda kukwana kuti ikunde kuramba kune electrode-workpiece interface. Yakaderera voltage inogona kukonzera kusagadzikana arcs uye hurombo weld mhando.
- Kudzora kweWeld Pool:Voltage inokanganisawo chimiro cheweld pool uye kugadzikana. Inobatsira kudzora kuyerera kwesimbi yakanyungudutswa uye inova nechokwadi chekugovaniswa kwakafanana, kudzivirira kukanganisa mu weld bead.
Optimizing Current uye Voltage
Kuti uwane yepamusoro-yemhando yekudzivirira nzvimbo welds, zvakakosha kukwirisa zvese zvazvino uye voltage marongero. Izvi zvinosanganisira kufunga nezvezvinhu zvakaita sekukora kwezvinhu, mhando yesimbi, uye dhizaini ye electrode. Vagadziri vanowanzopa welding nhungamiro uye kurudziro yezvakananga zvinhu uye maapplication.
Mukupedzisa, zvazvino uye voltage ndiwo akakosha paramita mukupikisa nzvimbo welding. Kunyatsogadzirisa marongero aya kwakakosha kuburitsa akavimbika uye akasimba welds. Kutsauka kubva kune zvinokurudzirwa zvinogona kukonzera kukanganisa, kuderedzwa kwesimba rebhondi, uye kukanganisa kwemaitiro kunogona kuitika. Naizvozvo, kunzwisisa hukama pakati pezvino, voltage, uye welding zvabuda kwakakosha pakuona kushanda kweresitorendi nzvimbo welding maitiro mumaindasitiri akasiyana.
