Iyini i-TIG Welding: Isimiso, Ukusebenza, Izisetshenziswa, Izicelo, Izinzuzo kanye Nemibi

Namuhla sizofunda ukuthi iyini i-TIG yokushisela isimiso sayo, ukusebenza, imishini, isicelo, izinzuzo kanye nokubi ngomdwebo wayo.I-TIG imele i-tungsten inert gas welding noma ngezinye izikhathi lokhu kushisela kwaziwa ngokuthi yi-gas tungsten arc welding.Kule nqubo yokushisela, ukushisa okudingekayo ukuze kwakhiwe i-weld kunikezwa i-arc kagesi enamandla kakhulu okuyifomu phakathi kwe-electrode ye-tungsten nesiqeshana somsebenzi.Kule welding i-electrode engadleki isetshenziswa engancibiliki.Ikakhulukazi akukho mpahla yokugcwalisa edingekayo kulokhuuhlobo lwe-weldingkodwa uma kudingekile, induku yokushisela ifakwa endaweni yokushisela ngokuqondile futhi incibilike ngesisekelo sensimbi.Le welding isetshenziswa kakhulu ukushisela i-aluminium alloy.

I-TIG Welding Principle:

I-TIG welding isebenza ngomgomo ofanayo wei-arc welding.Enqubweni yokushisela ye-TIG, i-arc eqinile ephezulu ikhiqizwa phakathi kwe-electrode ye-tungsten nesiqeshana somsebenzi.Kule welding ngokuvamile ucezu lomsebenzi luxhunywe kutheminali evumayo futhi i-electrode ixhunywe esikhumulweni esingesihle.Le arc ikhiqiza amandla okushisa aphinde asetshenziswe ukuhlanganisa i-metal plate byi-fusion welding.Kusetshenziswa futhi igesi evikelayo evikela i-weld surface kusuka ku-oxidization.

Umthombo wamandla wezisetshenziswa:

Iyunithi yokuqala yemishini ingumthombo wamandla.Umthombo wamandla ophezulu wamanje odingekayo ukuze kushiselwe i-TIG.Isebenzisa kokubili umthombo wamandla we-AC kanye ne-DC.Ikakhulu i-DC current isetshenziselwa insimbi engagqwali, iMild Steel, Copper, Titanium, Nickel alloy, njll. kanti i-AC current isetshenziselwa i-aluminium, i-aluminium alloy ne-magnesium.Umthombo wamandla uhlanganisa i-transformer, isilungisi kanye nezilawuli zikagesi.Ikakhulu i-10 - 35 V iyadingeka ku-5-300 A yamanje ukukhiqiza i-arc efanele.

TIG Isibani:

Kuyingxenye ebaluleke kakhulu ye-TIG welding.Lesi sibani sinezingxenye ezintathu eziyinhloko, i-tungsten electrode, ama-collets kanye nozzle.Lesi sithoshi kungaba ngamanzi apholisiwe noma umoya opholile.Kulesi sibani, i-collet isetshenziselwa ukubamba i-electrode ye-tungsten.Lezi zitholakala ngobubanzi obuhlukahlukene ngokuya ngobubanzi be-tungsten electrode.I-nozzle ivumela i-arc namagesi avikelekile ukuthi ageleze endaweni yokushisela.I-nozzle cross section incane enikeza i-arc eqinile.Kukhona ukudlula kwamagesi avikelekile ku-nozzle.Umlomo we-TIG udinga ukushintshwa ngezikhathi ezithile ngoba uyaguga ngenxa yokuba khona kwenhlansi eshubile.

I-Shielding Gas Supply System:

Ngokuvamile i-argon noma amanye amagesi angenayo asetshenziswa njengegesi evikelekile.Inhloso eyinhloko yegesi evikelekile ukuvikela i-weld kusuka ku-oxidization.Igesi evikelekile ayikuvumeli ukufika komoyampilo noma omunye umoya endaweni eshiselwe.Ukukhethwa kwegesi ye-inert kuncike ensimbi ezoshiselwa.Kukhona uhlelo olulawula ukuhamba kwegesi evikelekile endaweni eshiselwe.

Impahla Yokugcwalisa:

Ikakhulukazi ukushisela amashidi amancanyana akukho mpahla yokugcwalisa esetshenziswayo.Kepha nge-weld ewugqinsi, kusetshenziswa izinto zokugcwalisa.Izinto zokugcwalisa zisetshenziswa ngendlela yezinduku ezifakwa ngqo endaweni yokushisela ngesandla.

Ukusebenza:

Ukusebenza kwe-TIG welding kungafingqwa kanje.

• Okokuqala, i-voltage ephansi enamandla aphezulu okunikezwayo kwamanje okunikezwa umthombo wamandla ku-electrode yokushisela noma i-tungsten electrode.Ikakhulukazi, i
  I-electrode ixhunywe kutheminali enegethivu yomthombo wamandla kanye nomsebenzi kutheminali evumayo.
• Lokhu okunikezwayo kwamanje kwenza inhlansi phakathi kwe-tungsten electrode nomsebenzi.I-Tungsten iyi-electrode engasebenziseki, enikeza i-arc enamandla kakhulu.Le arc ikhiqize ukushisa okuncibilikisa izinsimbi eziyisisekelo ukwenza ijoyinti yokushisela.
• Amagesi avikelekile njenge-argon, i-helium inikezwa nge-valve yokucindezela kanye ne-valve elawulayo kuthoshi lokushisela.Lawa magesi enza isivikelo esingavumeli noma yimuphi umoya-mpilo namanye amagesi asebenzayo endaweni yokushisela.Lawa magesi adala i-plasma ekhulisa amandla okushisa e-arc kagesi ngaleyo ndlela ikhulise ikhono lokushisela.
• Ekushiseleni izinto ezincanyana akukho nsimbi yokugcwalisa edingekayo kodwa ukwenza ilunga eliwugqinsi okuthile okusetshenziselwa izigxobo ezaziphakelwa ngesandla umshiseli endaweni yokushisela.

Isicelo:

• Okuvame ukusetshenziselwa ukushisela i-aluminium ne-aluminium alloys.
• Isetshenziselwa ukushisela insimbi engagqwali, i-carbon base alloy, i-copper base alloy, i-nickel base alloy njll.
• Isetshenziselwa ukushisela izinsimbi ezihlukene.
• Isetshenziswa kakhulu ezimbonini ze-aerospace.

Okuhle nokubi:

Izinzuzo:

• I-TIG ihlinzeka ngokuhlanganyela okuqinile ngokuqhathanisa nokushisela kwe-arc yesihlangu.
• Ijoyinti alikwazi ukumelana nokugqwala futhi lidubule.
• Ukuqina okubanzi kokwakheka okuhlanganyelwe kungakheka.
• Ayidingi ukuguquguquka.
• Kungenziwa ngokuzenzakalela.
• Le welding ifaneleka kahle kumashidi amancane.
• Inikeza isiphetho esihle esingaphezulu ngenxa yokuthi i-splatter yensimbi enganaki noma izinhlansi ze-weld ezilimaza indawo engaphezulu.
• Ukuhlangana okungenasici kungadalwa ngenxa ye-electrode engasebenziseki.
• Ukulawula okwengeziwe kupharamitha yokushisela uma kuqhathaniswa nokunye ukushisela.
• Kokubili i-AC ne-DC yamanje ingasetshenziswa njengamandla kagesi.

Ububi:

• Ubukhulu bensimbi okumele bushiselwe bukhawulelwe mayelana ne-5 mm.
• Kwakudinga umsebenzi wamakhono aphezulu.
• Izindleko zokuqala noma zokusetha ziphezulu uma ziqhathaniswa ne-arc welding.
• Kuyinqubo ye-welding ehamba kancane.

Lokhu kumayelana nokushisela kwe-TIG, isimiso, ukusebenza, okokusebenza, isicelo, izinzuzo kanye nokubi.Uma unombuzo mayelana nalesi sihloko, buza ngokubeka amazwana.Uma uthanda lesi sihloko, ungakhohlwa ukwabelana ngaso ezinkundleni zokuxhumana.Bhalisa isiteshi sethu ukuze uthole izindatshana ezithakazelisayo.Siyabonga ngokuyifunda.
