Nzvimbo yezvombo zvewelding arsenals inowanikwa kurwisa basa rekugadzirisa simbi yakakura zvakanyanya nekufamba kwemakore, kusanganisira runyorwa rweanotsikisa alfabheti.
Kana iwe uri pamusoro pemakumi mashanu, iwe unogona kunge wakadzidza welding neSMAW (Shielded Metal Arc kana Electrode) welding muchina.
Ma1990 akatiunzira kurerukirwa kweMIG (simbi inert gasi) kana FCAW (flux-cored arc welding) welding, izvo zvakaita kuti mabuzzers akawanda aende pamudyandigere.Munguva pfupi yapfuura, tekinoroji yeTIG (tungsten inert gasi) yapinda muzvitoro zvekurima senzira yakanaka yekusevha simbi, aluminium uye simbi isina tsvina.
Kukurumbira kuri kukura kweakawanda-chinangwa welders ikozvino kunoreva kuti ese mana maitiro anogona kushandiswa mupakeji imwe.
Pazasi pane mapfupi welding makosi ayo anovandudza hunyanzvi hwako kune zvakavimbika mhedzisiro, zvisinei kuti unoshandisa welding process.
Jody Collier akazvipira basa rake kune welding uye welder kudzidziswa.Mawebhusaiti ake Weldingtipsandtricks.com uye Welding-TV.com akazadzwa nemazano anoshanda uye matipi emhando dzese dzewelding.
Iyo gasi inosarudzwa yeMIG welding icarbon dioxide (CO2).Kunyangwe CO2 ine hupfumi uye yakanakira kugadzira yakadzika yekupinda welds mumasimbi akakora, gasi rinodzivirira iri rinogona kupisa zvakanyanya kana uchipinza simbi dzakatetepa.Ndosaka Jody Collier achikurudzira kuchinja kune musanganiswa we75% argon uye 25% carbon dioxide.
"Oo, unogona kushandisa argon yakachena kuMIG weld aluminium kana simbi, asi zvinhu zvitete chete," akadaro."Zvimwe zvese zvakashongedzwa neArgon yakachena."
Collier anocherekedza kuti kune yakawanda gasi musanganiswa pamusika, senge helium-argon-CO2, asi dzimwe nguva yakaoma kuwana uye inodhura.
Kana uri kugadzirisa simbi isina tsvina papurazi, iwe uchada kuwedzera misanganiswa miviri ye100% argon kana argon uye helium yekugadzira aluminium uye musanganiswa we90% argon, 7.5% helium uye 2.5% carbon dioxide.
Kupinda kweMIG weld kunoenderana nekudzivirira gasi.Carbon dioxide (kumusoro kurudyi) inopa yakadzika yekupinda welding kana ichienzaniswa neargon-CO2 (kumusoro kuruboshwe).
Usati waita arcing paunenge uchigadzirisa aluminium, iva nechokwadi chekunyatsochenesa weld kuti usaparadza weld.
Weld cleaning kwakakosha nekuti alumina inonyunguduka pa3700°F uye base metals inonyunguduka pa1200°F.Naizvozvo, chero oxide (oxidation kana chena corrosion) kana mafuta pane yakagadziriswa nzvimbo inodzivirira kupinda kwesimbi yekuzadza.
Kubvisa mafuta kunouya pekutanga.Zvadaro, uye chete ipapo, kusvibiswa kweoxidative kunofanira kubviswa.Usachinje kurongeka, anoyambira Joel Otter weMiller Electric.
Nekukwira kwemukurumbira wemachina wekugadzira waya muma1990s, vakaedza uye vechokwadi nyuchi welders vakamanikidzwa kuunganidza guruva mumakona ezvitoro.
Kusiyana neaya mabuzzers ekare aishandiswa chete pakuchinjanisa ikozvino (AC) mashandiro, mawelder emazuva ano anoshanda pane ese ari maviri alternating current uye direct current (DC), achichinja welding polarity ka120 pasekondi.
Mabhenefiti anopihwa nekuchimbidza kwe polarity iyi akakura, anosanganisira kutanga nyore, kunamatira kushoma, spatter shoma, welds anoyevedza, uye nyore kuruka uye pamusoro welding.
Zvakasanganiswa nenyaya yekuti stick welding inoburitsa zvakadzika welds, yakanakira basa rekunze (MIG yekudzivirira gasi inopeperetswa nemhepo), inoshanda nemazvo nezvinhu zvakakora, uye inopisa kuburikidza nengura, tsvina, uye pendi.Michina yeWelding zvakare inotakurika uye iri nyore kushanda, saka iwe unogona kuona kuti nei itsva electrode kana akawanda-processor welding muchina wakakodzera kuisirwa mari.
Joel Orth weMiller Electric anopa anotevera electrode anonongedzera.Kuti uwane rumwe ruzivo shanya: millerwelds.com/resources/welding-guides/stick-welding-guide/stick-welding-tips.
Hydrogen gasi injodzi yakakomba yewelding, ichikonzera kunonoka kwewelding, HAZ kutsemuka kunoitika maawa kana mazuva mushure mekunge welding yapera, kana zvese zviri zviviri.
Zvisinei, kutyisidzira kwehydrogen kunowanzobviswa nyore nyore nekunyatsochenesa simbi.Inobvisa mafuta, ngura, pendi uye chero hunyoro sezvo ivo vari sosi yehydrogen.
Nekudaro, haidhirojeni inoramba iri kutyisidzira kana welding yakakwira-simba simbi (inowedzera kushandiswa mumidziyo yemazuva ano yekurima), makobvu esimbi profiles, uye munzvimbo dzinorambidzwa zvakanyanya.Paunenge uchigadzirisa zvinhu izvi, iva nechokwadi chekushandisa yakaderera hydrogen electrode uye preheat nzvimbo weld.
Jody Collier anonongedza kuti maburi ane sponji kana mabhuru madiki emhepo anoonekwa pamusoro peiyo weld chiratidzo chechokwadi chekuti weld yako ine porosity, iyo yaanofunga iyo yekutanga dambudziko newelding.
Weld porosity inogona kutora mafomu akawanda, anosanganisira pamusoro pores, wormholes, craters, uye cavities, anooneka (pamusoro) uye asingaoneki (yakadzika mu weld).
Collier anorayirawo kuti, “Dzimba ngarigare rakanyungudutswa kwenguva refu, zvichiita kuti gasi ribude mumoto risati raoma.”
Nepo madhayamita ewaya akajairika ari 0.035 uye 0.045 inches, waya diki dhayamita inoita kuti zvive nyore kugadzira weld yakanaka.Carl Huss weLincoln Electric anokurudzira kushandisa 0.025 ″ waya, kunyanya kana welding zvinhu zvitete 1/8 ″ kana zvishoma.
Akatsanangura kuti mawelders mazhinji anowanzo kugadzira welds akakurisa, izvo zvinogona kukonzera kupisa-kuburikidza.Diki dhayamita waya inopa yakatsiga weld pane yakaderera ikozvino zvichiita kuti isanyanya kupisa.
Ngwarira kana uchishandisa nzira iyi pane zvakakora (3⁄16″ uye zvakakora), sezvo 0.025″ waya yedhayamita inogona kukonzera kusakwana kunyungudika.
Kamwe chete kurota kunoitika kune varimi vachitsvaga nzira iri nani yekupinza simbi dzakatetepa, aruminiyamu uye simbi isina tsvina, TIG welders ari kuwedzera kuwanda muzvitoro zvepapurazi nekuda kwekukura kukuru kwevazhinji-processor welders.
Nekudaro, zvichibva pane zvakaitika kwauri, kudzidza TIG welding hakusi nyore sekudzidza MIG welding.
TIG inoda maoko maviri (imwe kuti ibate chitubu chekupisa muzuva-inopisa tungsten electrode, imwe kudyisa tsvimbo yekuzadza muarc) uye imwe tsoka (kushandisa tsoka inotsika kana ikozvino regulator yakaiswa patochi) Nzira nhatu dzekubatanidza dzinoshandiswa kutanga, kugadzirisa uye kumisa kuyerera kwezvino).
Kuti udzivise mhedzisiro seyangu, vanotanga uye avo vari kutsvaga kukwenenzvera hunyanzvi hwavo vanogona kutora mukana weaya TIG welding matipi, mumashoko eMiller Electric consultant Ron Covell, Welding Tips: Chakavanzika cheTIG Welding Success.
