Metal sheet welding chikamu chakakosha chekugadzirwa kwezvinhu zvakasiyana siyana zvesimbi. Spot welding inoshandiswa zvakanyanya muindasitiri yekugadzira mota, indasitiri yemidziyo yemidziyo yemumba, uye indasitiri yesimbi bhokisi. Tekinoroji yemazuva ano inoda kuwedzera yakakwira welding mhando. Muchikamu chino, isu tichatsanangura iyo nzvimbo welding maitiro zvakadzama uye kukurukura zvakanakiranzvimbo weldingmuindasitiri yemotokari.

Chii chinonzi Spot Welding

Spot welding imhando yeresistance welding. Zvinosanganisira kuisa maviri ekushanda pakati pepamusoro uye epasi maelectrode, kudzipisa nemagetsi emagetsi, uye kushandisa kumanikidza kugadzira mamiriro epurasitiki panzvimbo yekusangana yezvishandiso, zvichivabvumira kuti vabatane pamwechete. Nheyo yaro iri nyore: nekuitisa magetsi kuburikidza nemagetsi maviri emhangura, kushorwa kunowedzera tembiricha yezvishandiso zvebasa, zvichiita kuti zvinyunguduke uye zvibatane pamwe chete. Ndosaka ichinziwo resistance welding. Kuenzaniswa nemamwewelding process, spot welding haidi kuwedzera welding zvinhu, uye kushanda kuri nyore.

Nzira yekuona Weld?

1: Workpiece Surface Kuchenesa

Spot Welding Kazhinji Zvishandiso

Aluminium: Aluminium inonyanya kuwanda mumoto welding, kunyanya muindasitiri yemotokari, uko huremu hwayo hunogona kutsiva zvimiro zvakaomarara. Nekudaro, welding aluminum inonyanya kunetsa nekuda kweiyo yakakwirira conductivity, inoda zvakapetwa kaviri zvazvino zvezvakajairika. Naizvozvo, kana welding aluminium, unofanira kusarudza midziyo ine simba rakakwirira.

Simbi: Simbi ndiyo inonyanya kushandiswa mune nzvimbo welding. Icho chinhu chakaoma, uye zvinhu zvakawanda zvemotokari zvinoshandisa simbi. Spot welding inowanzo shandiswa kusungirira miviri yemotokari uye yakaoma nzungu zvinhu.

Mhangura: Spot welding mhangura inoda hunyanzvi hunyanzvi. Mhangura ine high thermal uye magetsi conductivity, zvichiita kuti ive nyore kunamatira kune electrode. Nokudaro, tinosarudza tungsten kana molybdenum electrodes. Munguva yekushongedza, brazing zvinhu zvinoda kuwedzerwa pakati pezvishandiso zviviri, saka brazing yemhangura inowanzoshandiswa.

Galvanized steel: Welding galvanized simbi yakanyanya kuoma pane welding simbi, inoda yakakwirira ikozvino. Nzvimbo yakanyunguduka yekuputira yakashongedzwa yakaderera pane yesimbi, saka zviri nyore kupfachukira uye kugadzira splashes panguva yewelding.

Workpiece Surface Kuchenesa

Usati welding, zvakakosha kutarisa kana maworkpiece ane ngura kana oxidation. Kana vakadaro, maworkpieces anoda kurapwa. Iwe unogona kushandisa sandpaper kana grinder kuita kuti pasi pave pakanaka. Zvikasadaro, pachave neakawanda splatter, izvo zvinogona kukanganisa welding mhando.

2: Kufunga 4 Variables Usati Welding uye Kuisa Paramita

Pressure

Kusarudza kumanikidza kwakakodzera kwakakosha. Kana iyo electrode pressure yakanyanya kana yakaderera, inogona kuderedza simba re weld uye kuwedzera kupararira kwayo. Kana welding, zvakakosha kuti titarise maitiro eiyo workpiece paunenge uchiisa kumanikidza.

Welding Nguva

Kuisa yakakodzera welding nguva kwakakosha. Kana iyo yelding nguva ipfupi, iyo workpiece inogona kusanyungudika zvakakwana kuti isangane nezvinodiwa zvekushongedza. Nekune rumwe rutivi, kana nguva yewelding yakarebesa, chishandiso chinowanzoita deformation, zvichiguma neakakura weld mamakisi.

Welding Current

Iko welding ikozvino uye nguva zvinopindirana, asi ivo vanewo miganhu. Kuwana chiyero chakanaka pakati pezviviri ndicho chinhu chikuru chekugadzira mawelds akakwana.

3: Spot Welding Machine

Midziyo inodiwa pakugadzira nzvimbo ndeyenzvimbo welding muchina, iyo inouya mumhando dzakasiyana. Kusarudza iyo chaiyo nzvimbo welding muchina zvinoenderana nehunhu hweiyo workpiece uye nezvinodiwa welding. Semuyenzaniso, kana iwe uchida kubatanidza pamwe maviri 2mm Stainless simbi mahwendefa kuti uwane inodiwa yevabereki simba rezvinhu, unozofanirwa kusarudza muchina wekuisa welding une simba repamusoro. Iyo yakajairwa nzvimbo welding muchina une 130KVA inogona kuita izvi. Nekudaro, kana iwe uchida weld 2mm gobvu aluminium mahwendefa, iwe unozoda yakajairwa nzvimbo welding muchina une 260KVA.

4: Isa Chishandiso Pakati PeElectrodes Uye Kutanga Welding

Kana uchinge wasarudza yakakodzera nzvimbo welding muchina, inguva yekutanga welding. Mushure mekubatanidza magetsi uye kugadzirisa ma parameters, isa iyo yakagadzirirwa workpiece pakati pezvivirielectrode cap. Dzvanya bhatani retsoka pedal, uye ma electrode anodzvanya pasi, kupisa uye kudzvanya maworkpieces, nekudaro achibatanidza mapoinzi ekusangana eaviri maworkpieces pamwechete.

5: Iyo Peel Test Mushure meWelding

Mushure mekucheka iyo workpiece, zvakaoma kuongorora kusimba kweweld neziso rakashama chete. Ndipo paunoda kushandisa zvishandiso kuyedza kusimba kweweld. Peel test inzira yakanaka. Panguva yekuyedzwa peel, tarisa iyo yakanyanya tensile simba inosvika pakupepura workpiece. Mamwe maworkpiece ane chaiwo anodiwa kune iyi kukosha kuti aone weld inogamuchirwa.

The Benefits Of Spot Welding For Automotive Indasitiri

Majoini Akasimba Uye Anogara kwenguva refu

Zvikamu zvakasungwa uchishandisa resistance welding zvinogadzira majoini akasimba uye akasimba. Zvigadzirwa zvakagadzirwa nenzira iyi zvakasimba uye zvakagadzikana, izvo zvakakosha muindasitiri yemotokari. Semuenzaniso, kana nzungu isina kunyatsobatanidzwa, inogona kukonzera tsaona mumugwagwa. Kurongeka uye kuvimbika kwakakosha muchikamu chemotokari, uko kunyangwe kukanganisa kudiki hakugamuchirwe. Naizvozvo, resistance welding inoita basa rakakosha mukuona kuti zviyero izvi zvazadzikiswa.

Kufanana Mumajoini

Mune welding mota zvikamu, hazvina kukosha chete kuti ma welds ave akasimba asiwo kuti zvigadzirwa zvakakandwa zvitaridzike zvinoyevedza. Resistance welding inogona kuita ichi chinodiwa. Kunyanya ye welding yemuviri wemota, yega yega weld point inofanirwa kunge isingaonekwe, sezvo ichikanganisa kunotevera kugadzirisa uye kutaridzika kwese kwemotokari.

Kubatanidzwa Kwezvinhu Zvakasiyana

Resistance welding inokodzerawo welding dissimilar materials. Muindasitiri yemotokari, pane zvikamu izvo simbi dzakasiyana dzinoda kubatanidzwa pamwechete. Apa ndipo panouya kuramba welding, nekuti inogona kujoinha zvinhu zvakasiyana, sesimbi nealuminium.

Welding Speed

Resistance welding haidi filler waya. Inokurumidza kupinza zvidimbu zvidiki. Muindasitiri yemotokari, umo madiki madiki akaiswa welded, maitiro acho anokurumidza uye nyore otomatiki, kuchengetedza vashandi uye kuwedzera welding kunyatsoshanda.

Kudzokorora

Nekuda kwekukodzera kwayo kune welding inodzokororwa zvigadzirwa, kuramba welding kungangoda parameter uye gadziriso yemidziyo paunenge uchichinja kune akasiyana zvirevo. Nekudaro, yakanyatsokodzera kune welding yakakwira-vhoriyamu zvigadzirwa. Zvigadzirwa zvemotokari, chaizvo nekuda kwehunhu uhu, tsvaga kuramba welding yakanyanya kukodzera indasitiri yemotokari.

Resistance welding iri kuwedzera kushandiswa zvakanyanya mumaindasitiri emazuva ano. Tekinoroji yayo inoramba ichivandudzwa kuti ienderane nekusimudzira maindasitiri, ichienda kune otomatiki. Kuti udzidze zvakawanda nezve resistance welding, ndapota tevera zvinyorwa zvedu.
