Resistance spot welding inzira yakajairika uye yakakosha mumaindasitiri akasiyana, asi wakambozvibvunza here nezvemhando dzakasiyana dzemacroscopic fractures dzinogona kuitika nenzira iyi yewelding?Muchinyorwa chino, isu tichaongorora akasiyana macroscopic fracture mhando dzinogona kucherechedzwa mukupikisa nzvimbo welding.
- Interfacial Fracture: Interface fractures, inozivikanwawo se "interface separation," inoitika pakusangana kwezvinhu zviviri zvakasungwa.Rudzi urwu rwekutyoka runowanzo kubatanidzwa nehusina kunaka weld uye inogona kubva kune nyaya senge kusakwana kudzvanywa kana zvisina kufanira welding paramita.
- Button Pullout: Mabhatani ekudhonza mafractures anosanganisira kubviswa kwesimbi yakanyungudutswa bhatani rakaumbwa panguva yewelding process.Izvi zvinogona kuitika kana weld material isina kunyatso sungirirwa kune base zvinhu, zvichitungamira kuti bhatani riburitswe panguva yekuyedzwa.
- Tear: Kutsemuka kwemisodzi kunoratidzwa nekubvaruka kwezvinhu zvepasi zvakatenderedza nzvimbo yeweld.Rudzi urwu rwekutyoka runowanzoitika kana paine kupisa kwakanyanya kupinza kana kana maparamita ewelding asina kudzorwa zvakanaka.
- Plug: Plug fractures inoitika kana chikamu chechimwe chezvinhu zvakashongedzwa zvakaparadzaniswa zvachose kubva kune imwe weld.Mhando iyi yekutyoka inogona kukonzerwa nezvinhu zvakasiyana siyana, kusanganisira kusvibiswa pamagetsi emagetsi emagetsi kana nzira isina kunaka yewelding.
- Edge Crack: Mupendero wakatsemuka makatsemuka anoumba padyo nekumucheto kwenzvimbo yakasungwa.Zvinogona kuguma kubva kune zvakasiyana siyana senge kutadza kugadzirira kwezvinhu kana kusarongeka kwe electrode.
- Nugget Fracture: Nugget fractures inosanganisira kukundikana kwepakati weld region, inozivikanwa se "nugget."Aya mafracture akakosha nekuti anogona kukanganisa kutendeseka kwese weld.Nugget fractures inogona kukonzerwa nekusakwana kwehudhini hwemagetsi kana zvisina kufanira welding paramita.
- Fissure: Fissure fractures inowanzoita madiki madiki kana kuputika mukati me weld material.Izvi zvinogona kunetsa kuona zvinoonekwa asi zvinogona kunetesa iyo yakazara weld chimiro.Fissures inogona kuitika nekuda kwenyaya neiyo welding process kana kunaka kwezvinhu zvinoshandiswa.
Kunzwisisa idzi mhando dzakasiyana dzemacroscopic fractures muresitorendi nzvimbo welding kwakakosha kuti ive nechokwadi chemhando uye kuvimbika kwemajoini akakwenenzverwa mukushandisa kwakasiyana.Welding vanoshanda uye vanoongorora vanofanirwa kusvinura mukuona uye kugadzirisa aya mafractures kuchengetedza kurongeka kwechimiro chezvakarukwa.
Mukupedzisa, resistance spot welding inogona kuguma nemhando dzakasiyana dzemacroscopic fractures, imwe neimwe iine seti yayo yezvikonzero uye zvinorehwa.Kuziva izvi zvakatyoka uye kugadzirisa zvikonzero zvadzo zvakakosha pakugadzira emhando yepamusoro welds inosangana neyakaomesesa miitiro yemaindasitiri emazuva ano.
