Welding ndarira pamba

In pakurapa asiri ferrous nesimbi kazhinji zvakaoma, sezvo mukuru tembiricha dzavo mumuviri zvivako kuchinja. Special nzeve anofanira ndarira nomoto, umo chinoshingaira zingi kwemvura. Pasinei nezvinetso pamwe chiwanikwa ichi ingangodaro kushanda mumhuri ezvinhu.

The chikuru zvinhu zvivako uye gadziriro

Asati Welding nendarira huchakurukurwa zvakadzama, zvinofanira kuva kuziva zvinoitwa acho. The chiwanikwa sezvamunoita zvinosanganisira vaviri vakaisvoipa vamire simbi - zvemhangura uye zinc. Zviri vokupedzisira vavo vanogona anosiyana 5-45 muzana. Zvinonzi akasuma kwete chete kuvandudza mumuviri ehupfumi, asiwo kuderedza mari yokupedzisira chigadzirwa.

Brass akaita vakawanda zvigadzirwa. Izvi zvinosanganisira marudzi ose plugs, adapters, nyere uye siyana decoration okunze. In gadzira yavo inogona kuwedzerwa alloying okunze sei unhu unhu:

• Tin anogona kuvandudza ngura kuramba waivako:
• Aluminum kusvika pamwero akazoita volatility pamusoro zingi;
• Nesilicon kunonatsiridza weldability duku kurasikirwa simba;
• Lead zvinoita kuti vawane kanenge yakasimba chigadzirwa kune nyore yokugadzirisa nayo okurwadzisa nzira.

Somunhu mbishi zvinhu nokuda kwezvifananidzo zvaAtemisi chiwanikwa zingi uye mhangura ndivo workpiece, uyewo dzimwe mhando nedzimwe simbi. Mune zvimwe zviitiko, inogona kushandiswa marara wayo kugadzirwa. Utsotso rinoitwa pamwe chiutsi kufefetedza achishandisa induction yamavira.

Nematambudziko pave zvachose kubatana

zvakanyanya uye zvakanaka rapera nomoto ndarira mumba, unofanira kuziva matambudziko pfungwa. Unsplit remubatanidzwa yaunganidzwa vemunzvimbo kudziyisa achava akavimbika chete pasi chaiwo zvinodiwa. Munguva basa hatigoni kukanganwa pamusoro kuchengeteka matanho, sezvo chafariz mugumisiro ngozi chiutsi dzinounzwa.

Huru dambudziko iri burnup yezviri zingi, iyo chokuita ayo pasi utsotso pfungwa (pakati 419 madhigirii). Vazhinji zvinhu mubasa nokupera. Saka vamwe mugove kunouya neZvapupu okisijeni, pova chena upfu riri dzakwidzwa akafukidza nzvimbo pedyo musono.

Zvokungwarira panguva pakugadzirisa

Self-nomoto nendarira havafaniri achitungamirira paumbwe nengozi mamiriro ezvinhu dzemuviri. Nokuda kunowedzera basa kusunungurwa kugadzikana yeimwe zvinofanira kushandiswa kana kushanda haende. Kunyange paaishandisa chaiwo nzira kurukutika zingi neeSultan kubva 25 kusvika 30 muzana.

It haabvumirwi tiite nomoto mabasa pedyo zvinhu uye zvinhu, nokukurumidza zvinobata moto. Pedyo kubasa havafaniri huni, huni Shavings, hemp kana gasi sepombi. Kwomutoro ezvinhu ndiwo pamberi mhepo mumba.

Urongwa okunze

Kana nomoto rinoitwa nendarira duku ukobvu, kuita pre-kudziyisa hakusi zvakakodzera. Kana mukomboni kuti hombe zvinhu vanorumbidzwa kuti kupisa kurapwa womunharaunda. gadziriro Edge kunogona kuitwa kuti zvinobikwa pakukora 1.5-6 mm.

Kana zvinhu zviri zvikuru muchinjikwa chikamu, chero zvazvingava, unofanira V-zvakaumbwa okurwadzisa sutures. Zviri nyore, asi hazvina Zvakanyanya Kunaka Panguva Yepamuviri. Zvakanakisisa aite vachiuraya X-kuumbwa panguva iyo, pakona yorusvingo yokutanga ndiyo 30-45 madhigirii por divi.

Types ndikarangarira ruzivo kuenzanisa

Muzviitiko zvakawanda, nendarira Welding pamwe argon. Technology migove remubatanidzwa mune imwe inert ezvinhu ichaongororwa kwazvo vaizotibata, sezvo anobvumira kuti vabudirire kumhanya basa. Zvimwewo zvakanakira nezvechisarudzo ichi zvinofanira pachena:

• mukana kuwana vazvo vane pachena geometry uye kuchena;
• homogeneity yechivako chacho mumunda kubatana zvachose;
• rakavimbika mapfundo;
• kunyatsoshanda nokuda kushandisa chipa tungsten electrodes.

Chimwe chidobi ndiyo gasi nomoto. It hakudi kushandisa kunobva magetsi simba, iyo anoruramiswa dzimwe nguva. In kushandisirwa zvinokwanisika mune zvakakwana siyana kudzora simba exiting murazvo. Zvakakodzera pakusarudza nomoto consumables anobudiswa yepamusoro welds.

Argon nomoto nendarira: urongwa tsananguro

Wednesday of kudzivirirwa gasi chinopa mukana kuderedza zvisina kunaka migumisiro mashoma. Welding ndarira ndarira musimboti ichi, icho anotuma vane kugara kuitika ane yakarurama polarity. Nokuda mukuru mukana nevutsva inokurudzirwa kuti kubata pokusvika nzvimbo pedyo refu chinhu chakakombama.

The electrode akaiswa mukati zhenje, inova conductive mashandiro. Pashure paizvozvo, kuti chinja chikwata. The oparesheni achabatsirwa wakawedzera mitswi, unowanikwa nokuda kunayisa pamusoro zingi mhute. The filler waya iri chakaunzwa pejoinhi noruoko.

Kazhinji nokubatanidza munhu rollers, pane chinoramba kubika michina. Kana embedding kuti mwena, zviri chinodiwa zvishoma kuderedza chinhu chakakombama voltage. Panguva yokupedzisira Danho zvakafanira kubvisa divi. The uchishandisa voltage anofanira kuderedzwa pakarepo, asi zvishoma nezvishoma.

Kushandiswa gasi michina

Munzvimbo dzine kusavapo yemagetsi riemukaari panobva rwokugadzira haagoni ingashandiswa. Zvisinei, muchiitiko ichi, hazvina bvumidzwa gasi nomoto endarira. Zvisinei, pamwe kushandiswa kwayo zvokufonongonwa remubatanidzwa vari vakawana kuti kunodiwa kushanda chaizvo zvinhu zvinokuvadza, iyo pamwe chete reokisijeni kuti aumbe putika wemisanganiswa.

Patinoedza tisanyanyozvidya kwemvura ine zingi kunogona kuva kuburikidza kushandiswa oxidizing burner murazvo rishande. Okisijeni kunge yakakura zvikuru kupfuura iya rehydrogen. Kana kugadzira inowanikwa rinooneka riri pechiso oxide firimu anobvumira pamwero kudzivirira zvinokukanganisa kubva zingi precipitates.

Kana Welding filler waya igadzikwe panguva necheparutivi rworwendo 15 kusvika 30 kurutivi micheto. Dzivisa transverse vibrations ari Implementation hwokushanda. The burner kunge ari necheparutivi 70 kusvika 80 madhigirii kuna workpiece.

Filler zvinhu anoiswa pamusoro yakaumbwa bhati zvakananga kupinda burner womoto. Regai kunyudza tsvimbo zvaishandiswa mukati musono. Kana tunneling chinhu chinodiwa kuomerera imwe nokukurumidza. Kazhinji ndiwo 15-25 masendimita paminiti.

Kana kubatana kusvika workpiece guru pakukora, ivo igadzikwe pa necheparutivi 10 kusvika 15 madhigirii kuna chinjikira. Welding ari ipapo kunze kuwedzera. Kazhinji, sirin'i majoini iyi zvisina asangana, sezvo zvinhu zviri flowable.

Welding pamwe nedzimwe simbi uye alloys

Dzimwe zvakafanira kubatanidza dzendarira nevamwe dissimilar zvinhu. Muchiitiko chino, unofanira kuziva pamusoro zvinhu mabasa akadai. Kana pamwe chete simbi angamuka zvimwe zvinetso, nokuda dzakasiyana physico-namakemikari zvechadenga alloys maviri.

A zvakafanana akaremara nomoto ndiko chimiro makatsemuka pamusoro simbi pamusoro zvakananga pasi marongera nendarira. Kuderedza ngozi urema izvi inokurudzirwa kushandisa nickel chiwanikwa. Best argon chidobi akaita kushandisa tungsten electrodes.

Tikafunga titanium pamwe alloys emhangura kungaita kuti paumbwe kwemakemikari zvisungo haungatani kuputsika. The yakanakisisa zvazviri kunokwanisika kana uchishandisa zvenguva inoisa. Ivo yakagadzirwa titanium chiwanikwa, doped pamwe niobium kana molybdenum. Mune zvimwe zviitiko, akabvumira kuti kushandisa wemishonga alloys.

The ehupfumi kuti niobium muviri zvikuru chakafanana titanium, saka kuchitsanangura welded kune nendarira. Zvisinei, kuvhiyiwa kunofanira kuitwa inert ezvinhu. Special Makamera anowanzoshandiswa, umo muchadenga rinodzorwa chose.

Chikamu chokupedzisira

Zvinofanira kucherechedzwa kuti kwendarira nomoto zvemichina ine zvachiri kuti zvinofanira kufungwa paaisika zvachose kubatana pamba pasina kunobatanidza unyanzvi. Kudzidza zvose acho ingangodaro kuita yakachengeteka kwokubatana blanks. Achitaura pakusarudza nzira, zvinonyanya novimba kuvapo wakananga Hardware uye uchishandisa mamiriro.
