Resistance spot welding inzira inoshandiswa zvakanyanya mukugadzira nekuvaka maitiro. Zvinosanganisira kubatanidzwa kwemarata maviri kana anopfuura nekuisa kumanikidza uye magetsi emagetsi kugadzira weld. Iwo anokonzeresa welding majoini anoratidza akati wandei akasarudzika maitiro akakosha kuti unzwisise kunaka uye kutendeseka kweiyo weld. Muchinyorwa chino, isu tichaongorora zvakakosha majoini ewelding anogadzirwa neresistance spot welding michina.
- Nugget size:Imwe yeanonyanya kukosha maitiro ndeye saizi ye weld nugget. Iyo nugget ndiro dziva resimbi rakanyungudutswa rakagadzirwa panzvimbo yekubatana pakati pemagetsi. Inofanira kunge iine saizi chaiyo uye chimiro, iyo inogona kusiyana zvichienderana neiyo welding paramita uye ukobvu hwezvinhu. Iyo yakanaka nugget inowanzotenderedzwa uye yakafanana muhukuru, zvichireva yakasimba uye yakavimbika weld.
- Kudzika Kwekupinda:Kudzika kune iyo weld inowedzera mukati mechinhu chinhu chakakosha chemhando ye weld. Kupinda kwakakodzera kunovimbisa chisungo chakasimba pakati pemashizha ari kubatanidzwa. Kupinda kusina kukwana kunogona kuderedza mubatanidzwa, nepo kupinda kwakanyanya kunogona kutungamirira mukupisa-kuburikidza kana kukanganisa kwezvinhu.
- Weld Spatter:Munguva yekugadzira, madonhwe esimbi akanyunguduka anogona kudzingwa kubva muguge uye kumhara panzvimbo dzakatenderedza. Aya madonhwe, anozivikanwa se weld spatter, anogona kukanganisa kutaridzika uye kutendeseka kwemubatanidzwa. Mawelds emhando yepamusoro anoratidza spatter shoma.
- Weld Uniformity:Kuenderana uye yunifomu weld kwakakosha kuti uwane kutendeseka kwechimiro. Kusiyana kwehukuru hwe nugget, kudzika kwekupinda, kana kupararira kwekupisa pajoinhi kunogona kukonzera kushaya simba kana kukanganisa kunokanganisa kusimba kweweld.
- Interfacial Bond:Iyo yekubatanidza pakati pemarata maviri esimbi inofanirwa kuumba yakasimba metallurgical bond. Kubatana kwakanyatsobatanidzwa kunovimbisa kuti mapepa anoita sechinhu chimwe chete, achiwedzera kutendeseka kwemaitiro. Kusasimba kwekubatana kwechiso kunogona kutungamira mukuparadzaniswa kana delamination yemashiti.
- Nzvimbo Yakakanganiswa Nekupisa (HAZ):Yakatenderedza nugget inzvimbo inobatwa nekupisa, uko simbi inosangana nemhando dzakasiyana dzekupisa kwemafuta. Zvakakosha kudzikisa saizi yeHAZ kudzivirira shanduko yezvinhu, sekuoma kana brittleness, izvo zvinogona kukanganisa kushanda kweweld.
- ChitarisikoKuonekwa kwekuonekwa kweweld joint inowanzova chiratidzo chehutano hwayo. Iyo yakanyatso itwa yekudzivirira nzvimbo weld inofanirwa kuve yakatsetseka uye inowirirana, isina zvimiro, mitswe, kana kunyanyisa kushanduka.
- Kuedza uye Kuongorora:Kuti ive nechokwadi chekuvimbika kweyekudzivirira nzvimbo welds, dzakasiyana-siyana dzisiri dzekuparadza uye dzinoparadza nzira dzekuyedza dzinoshandiswa. Izvi zvinosanganisira ongororo yekuona, ultrasonic bvunzo, X-ray kuongororwa, uye peel test, pakati pezvimwe.
Mukupedzisa, kunzwisisa hunhu hwewelding majoini anogadzirwa neanopesana nzvimbo welding michina kwakakosha kuti uwane emhando yepamusoro uye yakavimbika welds. Vagadziri uye nyanzvi dzewelding dzinofanirwa kunyatso tarisisa maficha aya kuti vaone kuti zvinhu zvakasungwa zvinosangana nezvinodiwa zvesimba uye kusimba, kunyanya mumashandisirwo akakosha akadai sekugadzira mota neaerospace. Kudzidzira kwakaringana, kwakanyatso kudzora parameter, uye kuomarara kwemhando yekudzora matanho ndiwo akakosha kuti arambe achigadzira epamusoro ekupikisa nzvimbo welds.
