Welding ndeimwe yeanonyanya kukosha maitiro muindasitiri yekugadzira, uye marobhoti ekuwedha akawana mukurumbira wakakura mumakore achangopfuura nekuda kwekugona kwavo mabhenefiti pamusoro pechinyakare manyorero ekugadzira nzira. Welding marobhoti mashini otomatiki anogona kuita welding mabasa nehupamhi hwepamusoro uye nekumhanya, izvo zvinovandudza kugona kwese uye kunaka kweiyo welding process. Nekudaro, senge chero imwe nzira yekugadzira,welding nemarobhotizvinogonawo kutungamirira kune hurema hunogona kukanganisa kunaka kweweld. Muchikamu chino, isu tichatarisa pane zvakajairika welding defects mumarobhoti welding uye nzira yekuzvigadzirisa.
Common welding defects mune welding marobhoti
1. Porosity: Porosity chirema chewelding chinoitika kana mabubbles egasi akavharirwa musimbi inokwenenzverwa panguva yewelding. Porosity inogona kukonzerwa nezvinhu zvakasiyana, senge kusakwana kudzivirira gasi kuyerera kana simbi dzakasvibiswa dzekuzadza.
2. Kusanganiswa kusina kukwana: Ichi chikanganiso chinoitika kana pane kukundikana mukugadzirisa welding, izvo zvinoguma nekunyunguduka kusina kukwana uye kubatana kwesimbi yepasi. Kusanganiswa kusina kukwana kunogona kukonzerwa neasina kunaka welding parameters kana husina kunaka welding techniques.
3. Undercutting: Ichi chirema che weld apo weld ikanyanya kudzika, uye mipendero yemasimbi epasi inonyungudika zvakanyanya. Undercutting inogona kukonzerwa nekumhanyisa welding, isina kukodzera torch angle, kana kushaikwa kwesimbi yekuzadza.
4. Kupinda kwakanyanyisa: Kupinda kwakanyanyisa kunoitika apo simbi ye weld inopinda yakadzika zvakanyanya mukati mezvinhu zvepasi, zvichiita kuti kusava nesimba kwemaitiro mu weld. Kukanganisika uku kunogona kukonzerwa nekuwedzeredza welding ikozvino kana kutadza kufamba kwetochi.
5. Weld metal cracking: Weld metal cracking inoitika apo kushungurudzika kunoshandiswa kune weld, zvichiita kuti iparadze. Ichi chikanganiso chinogona kukonzerwa nezvinhu zvakasiyana, senge simbi dzisina kufanira dzekuzadza, zvisizvo zvewelding paramita, kana humbowo husina kunaka hwewelding.
Kugadzirisa kukanganiswa kwewelding mumarobhoti welding
1. Chengetedza nzira dzakakodzera dzekugadzirisa: Nzira dzakakodzera dzekugadzira dzakakosha kuti uwane mashizha emhando yepamusoro pasina kukanganisa. Izvo zvakakosha kuve nechokwadi kuti marobhoti ekushongedza marobhoti akarurama uye kuti maparamendi ewelding akaiswa nenzira kwayo zvichienderana nechinhu uye application iri kusungirirwa.
2. Iva nechokwadi chekuchengetedza kwakakodzera kwemidziyo: Kugara uchigadzirisa marobhoti welding uyemidziyo inobatanidzwa mukugadzira weldingzvakakosha pakudzivirira kukanganisa. Welding marobhoti uye midziyo inoshandiswa mukugadzira welding inoda kugara ichiongororwa kuti yakasakara uye kubvaruka uye kucheneswa kana zvichidikanwa.
3. Shandisa gasi rekudzivirira rakakodzera: Gasi rekudzivirira rinoshandiswa mukugadzira welding yakakosha mukudzivirira kukanganisa kwakadai seporosity. Izvo zvakakosha kushandisa iyo chaiyo yekudzivirira gasi uye chiyero chekuyerera kuti uve nechokwadi chekuti weld yakachengetedzwa zvakaringana kubva mukusvibiswa kwemhepo.
4. Shandisa simbi dzemhando yekuzadza: Kushandisa simbi dzemhando yekuzadza kwakakosha mukuwana mawelds emhando yepamusoro. Masimbi asina kunaka ekuzadza simbi anogona kunge aine tsvina iyo inogona kukonzera kuremara muweld. Izvo zvakakosha kuti ushandise simbi dzekuzadza idzo dzakakodzera zvinhu zviri weld uye kuve nechokwadi kuti zvakachengetwa munzvimbo yakaoma uye yakachena.
5. Chengetedza maitirwo ewelding: Kuongorora maitirwo ewelding kwakakosha pakuona zvikanganiso nekukasika zvisati zvanyanya. Welding marobhoti anogona kurongwa kuti atarise maitirwo ewelding uye kunyevera vashandisi nezve chero kutsauka kubva kune yakatarwa paramita inogona kuratidza kukanganisa.
6. Vadzidzisi vezvitima: Kudzidziswa kwakakodzera kwevashandi kwakakosha mukudzivirira kukanganisa kwewelding. Vashandi vanofanirwa kudzidziswa nezve nzira dzakakwana dzewelding, mashandiro emidziyo, uye kugadzirisa kuti vaone kuti maitirwo ewelding anoitwa nemazvo.
Welding defects inogona kukanganisa kunaka uye kushanda kweiyo welding process. Nekudaro, nekutevera matipi ari pamusoro apa, marobhoti ekushongedza anogona kushandiswa kugadzira emhando yepamusoro welds ane hurema hudiki. Kugadzirisa kwakaringana kwemidziyo, kushandisa simbi dzakakwana dzekuzadza uye kudzivirira magasi, kutarisa maitiro ekuwelda, uye kudzidzisa vanoshanda kwakakosha mukudzivirira hurema hwewelding uye kuve nechokwadi chemhando yepamusoro welds. Nepo kumwe kukanganisa kungave kusingadzivisike, kushandisa nzira dzakanakisa kunoita kuti vaonekwe uye vagadziriswe nekukurumidza. Nekuenderera mberi kufambira mberi muhunyanzvi hwekushongedza uye kushandiswa kwemarobhoti ekuwelda, indasitiri yekugadzira inogona kutarisira kugadziridzwa kwewelding maitiro ane emhando yepamusoro welds.
