Maitiro Ekubatanidza Anoshandiswa muMetallurgy
Kugadzira simbi isayenzi inodzidza hunhu hwesimbi nemakemikari. Chimwe chinhu chakakosha pakugadzira simbi inzira yekubatanidza simbi, inova nzira yekubatanidza simbi mbiri kana kupfuura nekunyungudutsa pamusoro padzo nekuwedzera zvinhu zvinozadza. Heano mamwe matekiniki ekubatanidza simbi anowanzoshandiswa mukugadzira simbi:
1. Metal Inert Gasi Welding (MIG/MAG)
MIG (Metal Inert Gas) neMAG (Metal Active Gas) inzira mbiri dzekubatanidza dzinowanzoonekwa dzakafanana nekuti dzinoshandisa musimboti mumwe chete: gasi rinodzivirira kudzivirira kusvibiswa kwemhepo munzvimbo yekusanganisa. Musiyano uri murudzi rwegasi rinoshandiswa: MIG inoshandisa gasi risingashande senge argon kana helium, nepo MAG ichishandisa gasi rinoshanda senge carbon dioxide.
Zvakanakira zvehunyanzvi uhu zvinosanganisira:
- Kugadzirwa kwepamusoro uye kupinda zvakanaka kwewelding.
- Inogona kushandiswa pamhando dzakasiyana dzesimbi.
– Yakakodzera kupinza otomatiki uye semi-automatic.
2. Kuwedera kweArc yemagetsi (SMAW)
Kuwelda kwesimbi yakavharirwa (SMAW), iyo inowanzozivikanwa seyemagetsi ekugadzira arc welding, inzira yekuwelda inoshandisa electrode yakavharirwa inonyungudutsa simbi yepasi nechinhu chakanyungudutswa kuti igadzire chisungo. Iyi electrode yakavharirwa inoshandawo kudzivirira simbi yakanyungudutswa kubva mukuoxidation uye kusvibiswa kwemhepo.
Zvakanakira zveSMAW welding zvinosanganisira:
- Inogona kushandiswa pamhando dzakasiyana dzesimbi nenzvimbo dzekunamira.
- Inochinjika zvakanyanya pakushanda mumaindasitiri madiki kana mapurojekiti emumunda.
- Hazvidi mamwe maturusi akaomarara.
Zvisinei, zvipingamupinyi zvikuru zvayo idambudziko rekugadzira uye kudiwa kwehunyanzvi hwepamusoro kubva kune vanoshanda nayo.
3. Tungsten Inert Gas (TIG) Welding
TIG (Tungsten Inert Gas) kana kuti Gas Tungsten Arc Welding (GTAW) inzira yekuwedera inoshandisa tungsten electrode isinganyungudike. Chidziviriro chegasi chisina simba chakadai seargon kana helium chinoshandiswa kudzivirira nzvimbo yekuwedera kubva mukusvibiswa.
Mabhenefiti eTIG technique:
- Mhedzisiro yemhando yepamusoro yekuwelda ine chitarisiko chakanaka.
- Inogona kushandiswa kusanganisa simbi dzakatetepa uye zvinhu zvakasiyana-siyana zvakaita setitanium.
- Kudzora kwakanaka kupisa uye kupinda kwemvura.
Zvisinei, chimwe chezvakaipira zvikuru ndechekuti kumhanya kwekugadzira kunononoka kupfuura mamwe matekiniki uye kunoda hunyanzvi hwepamusoro.
4. Kuwedera kweOxy-Acetylene
Kupinza gasi rakanyungudika kunoshandisa musanganiswa weokisijeni neacetylene gases kugadzira moto unopisa zvikuru. Nzira iyi inowanzoshandiswa pakupinza, kucheka, nekugadzirisa simbi.
Zvakanakira zvekubatanidza gasi rakanyungudutswa zvinosanganisira:
- Zviri nyore uye zviri nyore kutakura michina.
- Kuchinjika zvakanyanya mumamiriro akasiyana-siyana uye munzvimbo dzebasa.
- Inogona kushandiswa pamhando dzakasiyana dzesimbi.
Zvisinei, kupinza gasi rakanyungudutswa kunoda kungwarira kwakanyanya nekuda kwenjodzi yekubvira moto nekuputika kunokonzerwa nekushandiswa kwemagasi eokisijeni neacetylene.
5. Kushongedza Plasma
Kusonta plasma inzira yepamusoro inoshandisa arc yemagetsi yakanangana kunyungudutsa simbi. Gasi replasma rinopa simba kuchoto ichi che arc uye rinogadzira tembiricha yakakwira zvikuru, zvichiita kuti kusonta kuve kwakanyatsonaka.
Zvakanakira zvikuru zve plasma welding zvinosanganisira:
– Kupinza simbi nekukurumidza uye kupinda mukati memvura yakadzika.
- Inogona kushandiswa pasimbi yakakora uye yakatetepa.
- Kutarisirwa kwakanaka kwenzvimbo inopisa.
Zvisinei, michina yekushongedza plasma inowanzo kudhura uye inoda vashandi vakadzidziswa zvakanyanya.
6. Kukwesha Kwemagetsi Nekusanganisa (FSW)
Kukwesha simbi neFriction Stir inzira itsva yekubatanidza simbi isingade kunyungudutsa simbi. Pane kudaro, chishandiso chakakosha chinogadzira kupisa kuburikidza nekukweshana uye chinosanganisa simbi nekukurunga zvinhu zviri pajoini.
Zvimwe zvakanakira FSW zvinosanganisira:
- Kuwedera kusina kukanganiswa kwakanyanya uye kusashanda zvakanaka.
– Inogona kusanganisa simbi dzakaoma kusanganisa nenzira dzechinyakare, dzakadai sealuminium/lithium alloys.
- Hunhu hwekunamira hunogara huripo uye hwakasimba.
Zvisinei, nzira iyi yakakodzera chete kune majoini akapfava kana majoini emuhudyu ane maumbirwo akareruka kana kuti akatenderera.
7. Kushongedza neLaser
Kupinza neLaser kunoshandisa chiedza cheLaser chakanyatsogadzirwa kuti simbi inyunguduke nekudziya. Iyi nzira inonyanya kubatsira pakushandisa zvinoda kupinza nekushandisa nemazvo.
Zvakanakira nzira dze laser welding zvinosanganisira:
- Kunyatsorongeka kwakanyanya uye nzvimbo isinganyanyi kukanganiswa nekupisa.
– Kumhanya kwakanyanya kwekushongedza.
- Kukanganisa kushoma uye kushanduka.
Dambudziko nderekuti michina inodhura uye kudiwa kwehurongwa hwakakosha hwekuchengetedza kuti hushande nemalaser ane simba guru.
8. Kushongedza kweUltrasonic
Kushongedza ne ultrasonic inzira yekushongedza inoshandisa high-frequency ultrasonic vibrations kubatanidza zvinhu zviviri pamwe chete. Maitiro aya anowanzo shandiswa pamapurasitiki, asi anogonawo kushandiswa kusimbi dzakareruka, dzakadai searuminiyamu nemhangura.
Zvakanakira zvikuru zve ultrasonic welding:
- Maitiro acho anokurumidza, kazhinji anotora masekondi mashoma chete.
– Hazvidi kuti kupisa kupinde, zvichideredza njodzi yekushanduka kwekupisa.
- Inoshanda zvikuru pakugadzira zvinhu zvidiki zvakawanda.
Zvisinei, nzira iyi haina kukodzera simbi dzakakora uye dzakaoma.
Kumwe Kushongedza
Dzimwe nzira dzekupinza dzinofanira kutaurwa ndedzinotevera:
– Kukwesha kwesimbi: Kunoshandiswa kukwesha simbi dzakatetepa nekuisa simba remagetsi panzvimbo ine simba shoma.
– Kunyungudutsa Arc Welding (SAW): Kugadzira welds neelectrode inonyunguduka nguva dzose pasi pechikamu cheflux yakanyungudutswa, yakakodzera kugadzirwa kwehuwandu hwakawanda uye hunhu hwakafanana.
Mhedziso
Maitiro akasiyana-siyana ekunamira mukugadzira simbi ane zvakanakira zvawo zvakasiyana, zvichiita kuti zvive zvakanaka pakushandiswa kwacho. Zvakakosha kufunga nezvehunhu hwezvinhu zvinonamira, pamwe nemamiriro ekunze nemamiriro ekushanda, pakusarudza nzira yakakodzera yekunamira. Kuvandudzwa kuri kuramba kuchienderera mberi muhunyanzvi hwekunamira kunoramba kuchivandudza mhando, kushanda, uye kushanda zvakanaka kwekunamira simbi, zvichiita kuti kugadzira simbi kuve kwakanyatsogadzirwa uye kwakavimbika mumaindasitiri akasiyana-siyana.
Nekufambira mberi kwetekinoroji, tinogona kuona matekiniki matsva ekunamira mune ramangwana anoshanda zviri nani, akachengeteka, uye asingadhuri. Nokudaro, kunzwisisa matekiniki aripo ekunamira uye kugara tichidzidza nezvezvinhu zvitsva zvakakosha kune vese vanoita zvesimbi.
