01. Tsanangudzo pfupi
Spot welding inzira yekurwisa simbi inosungirirwa pamakumbo majoini uye kudzvanywa pakati pemaelectrode maviri, uchishandisa kupisa kupisa kunyungudutsa simbi yepasi kuti igadzire majoini ekutengesa.
Spot welding inonyanya kushandiswa mune zvinotevera zvinhu:
1. Kupindirana kwezvidimbu zvitete zvekutsika ndiro, senge mota cabs, macompartments, machira ekukohwa hove, nezvimwe.
2. Ndiro yakatetepa uye maumbirwo esimbi akaumbwa uye zvimiro zveganda, senge ngoro yepadivi madziro uye sirin'i, mapaneru engoro dzetirairi, batanidza mafaniro ekukohwa, nezvimwe.
3. Masikirini, mafuremu emuchadenga nemasimbi emuchinjiko, nezvimwe.
02.Zvinhu
Munguva yewelding, iyo weldment inoumba mubatanidzwa unopindirana uye inotsikirirwa pakati pema electrode maviri. Hunhu hwayo hukuru ndeiyi:
1. Panguva yekugadzira nzvimbo, nguva yekupisa yenzvimbo yekubatanidza ipfupi kwazvo uye kukurumidza kwewelding kunokurumidza.
2. Spot welding inongopedza simba remagetsi uye haidi kuzadza zvinhu, flux, gasi, nezvimwe.
3. Hunhu hwenzvimbo welding hunonyanya kuvimbiswa neapo welding muchina. Iine mashandiro ari nyore, dhigirii repamusoro remakina uye otomatiki, uye kugadzirwa kwakanyanya.
4. Kuderera kwebasa rakaoma uye mamiriro akanaka ekushanda.
5. Sezvo welding inopedzwa munguva pfupi uye inoda yakakura ikozvino uye kumanikidzwa, chirongwa chekugadzirisa chirongwa chacho chinonyanya kuoma, muchina welding une simba guru remagetsi, uye mutengo wezvigadzirwa zvakakura.
6. Zvakaoma kuitisa kuongororwa kusingakuvadzi kwemajoini e solder.
Xinfa welding midziyo ine hunhu hwemhando yepamusoro uye mutengo wakaderera. Kuti uwane ruzivo, ndapota shanya:Welding & Cutting Manufacturers - China Welding & Cutting Factory & Suppliers (xinfatools.com)
03.Kushanda maitiro
Pamberi pekuputika, pamusoro pebasa rekushanda rinofanira kucheneswa. Iyo inowanzoshandiswa yekuchenesa kurapa ndeye pickling, ndiko kuti, iyo inotanga kunyungudutswa mune inopisa sulfuric acid ine mutsara we10%, uye yozoshambidzwa mumvura inopisa. Iyo chaiyo welding process ndeiyi inotevera:
(1) Dyisa iyo workpiece yakabatana pakati pepamusoro nepasi maelectrode eiyo nzvimbo welding muchina uye woisunga;
(2) Kana magetsi akaiswa, nzvimbo dzekusangana dzezviviri zvebasa dzinopisa, dzakanyungudika zvishoma, uye nugget inoumbwa;
(3) Chengetedza dzvinyiriro mushure memagetsi kudzima, kuitira kuti nugget yakanyungudutswa itonhore uye igosimba pasi pekumanikidzwa kuita majoini anotengeswa;
(4) Bvisa kumanikidzwa uye tora workpiece.
04.Kufurira zvinhu
Izvo zvakakosha zvinopesvedzera zvinhu zvemhando yewelding zvinosanganisira welding ikozvino uye nguva yesimba, electrode pressure uye shunt, nezvimwe.
1. Welding ikozvino uye simba-panguva
Zvinoenderana nehukuru hweiyo welding ikozvino uye kureba kwesimba-nenguva, spot welding inogona kupatsanurwa mumhando mbiri: hard gauge uye soft geji. Tsanangudzo inopfuura yakakura ikozvino munguva pfupi inonzi yakaoma tsanangudzo. Iyo ine mabhenefiti ekugadzirwa kwepamusoro, hupenyu hurefu hwe electrode, uye diki deformation ye weldment, uye inokodzera simbi yekushongedza ine yakanaka yekupisa conductivity. Geji rinopfuura diki ikozvino kwenguva yakareba inonzi geji yakapfava, ine chibereko chakaderera uye inokodzera simbi inopinza iyo inowanzoomesa.
2. Electrode pressure
Panguva yekugadzira nzvimbo, kudzvanywa kunoitwa paweldment neelectrode kunonzi electrode pressure. Iyo electrode pressure inofanira kusarudzwa zvakakodzera. Kana kudzvinyirirwa kwakakwirira, shrinkage uye shrinkage cavities zvinogona kuitika apo nugget inosimbisa inogona kubviswa. Zvisinei, kushorwa uye ikozvino density ye electrode yakaderedzwa, zvichiita kuti kusakwana kupisa kwe weldment uye kuderedzwa kwehupamhi hwe nugget. Simba rejoint solder rinoderera. Saizi ye electrode pressure inogona kusarudzwa zvichibva pane zvinotevera zvinhu:
(1) Material weldment. Iyo yakakwirira yekushisa kwepamusoro simba rezvinhu. Iyo yakakura iyo electrode pressure inodiwa. Naizvozvo, kana welding simbi isina-stainless uye simbi isingapise kupisa, yakakwirira electrode pressure inofanirwa kushandiswa pane kana welding low carbon steel.
(2) Welding parameters. Iyo yakanyanya kuoma iyo welding yakatarwa, iyo yakakura iyo electrode pressure.
3. Kutsauka
Munguva yekugadzira nzvimbo, ikozvino inoyerera kunze kweiyo main welding circuit inonzi shunt. Iyo shunt inoderedza ikozvino inoyerera kuburikidza nenzvimbo yewelding, zvichikonzera kusakwana kwekudziya, zvichikonzera kuderera kukuru kwesimba rejoinhi rekutengesa uye kukanganisa kunaka kwewelding. Izvo zvinhu zvinokanganisa dhigirii rekutsauka zvinonyanya zvinosanganisira zvinotevera zvinhu:
(1) Weldment ukobvu uye welding point spacing. Sezvo kureba pakati pemajoini ekutengesa kunowedzera, shunt kuramba inowedzera uye dhigirii reshunting rinoderera. Kana yakajairwa point spacing ye30 kusvika 50 mm ikashandiswa, iyo shunt current account ye25% kusvika 40% yezvese zvazvino, uye nekukora kweweldment kunodzikira, degree reshunting rinodererawo.
(2) Surface mamiriro e weldment. Kana paine maokisi kana tsvina pamusoro peiyo weldment, kusangana kwekupokana pakati pemaviri weldment kunowedzera, uye ikozvino inopfuura nepakati penzvimbo yewelding inoderera, ndiko kuti, dhigirii reshunting rinowedzera. Iyo workpiece inogona kuve yakabikwa, sandblasted kana kupushwa.
05.Safety precautions
(1) Chitsiko chetsoka chemuchina welding chinofanira kunge chine chivharo chakasimba chekudzivirira kudzivirira kuita netsaona.
(2) Nzvimbo yekushandira inofanira kunge yakashongedzerwa nemabaffles kudzivirira kuti pfarivari dzinoshanda dzirege kubhururuka.
3
(4) Nzvimbo inoiswa muchina we welding inofanira kugara yakaoma, uye pasi panofanira kugadzirwa ne-anti-skid plates.
(5) Mushure mekunge basa rekushongedza rapera, magetsi anofanira kubviswa, uye kushandura mvura inotonhorera inofanira kuwedzerwa kwemasekonzi gumi isati yavhara. Kana tembiricha yadzikira, mvura yakaunganidzwa mumvura inofanira kubviswa kudzivirira kutonhora.
