Yintoni i-TIG Welding : Umgaqo, ukusebenza, izixhobo, izicelo, izinto eziluncedo kunye nezingeloncedo

Namhlanje siza kufunda malunga nokuba yintoni na i-TIG ukuwelda umgaqo wayo, ukusebenza, izixhobo, isicelo, iingenelo kunye nobubi kunye nomzobo wayo.I-TIG imele i-tungsten inert yegesi yokuwelda okanye ngamanye amaxesha le welding yaziwa ngokuba yi-gas tungsten arc welding.Kule nkqubo ye-welding, ubushushu obufunekayo ukwenza i-weld bubonelelwa nge-arc yombane enamandla kakhulu ephakathi kwe-electrode ye-tungsten kunye nomsebenzi.Kule welding i-electrode engasetyenziswayo isetyenziswa enganyibilikiyo.Ubukhulu becala akukho nto yokuzalisa efunekayo kule ntouhlobo weldingkodwa ukuba kuyafuneka, intonga ye-welding ifakwe kwindawo ye-weld ngokuthe ngqo kwaye inyibilika ngesiseko sesinyithi.Le welding isetyenziswa ikakhulu welding aluminiyam ialloy.

Umgaqo-siseko we-TIG we-Welding:

I-TIG welding isebenza kumgaqo ofanayo wewelding arc.Kwinkqubo ye-TIG ye-welding, i-arc ephakamileyo ephakamileyo iveliswa phakathi kwe-electrode ye-tungsten kunye nomsebenzi.Kule welding ubukhulu becala isiqwenga umsebenzi iqhagamshelwe terminal elungileyo kwaye electrode iqhagamshelwe terminal negative.Le arc ivelisa amandla obushushu aphinda asetyenziswe ukudibanisa ipleyiti yesinyithi ngeukudibanisa ukuwelda.Kukwasetyenziswa igesi ekhuselayo ekhusela umphezulu we-weld kwi-oxidization.

Umthombo waMandla weSixhobo:

Iyunithi yokuqala yezixhobo ngumthombo wamandla.Umthombo wamandla ophezulu ngoku ofunekayo kwi-TIG welding.Isebenzisa zombini umthombo wamandla we-AC kunye ne-DC.Ikakhulu i-DC yangoku isetyenziselwa intsimbi engatyiwa, iMild Steel, Copper, Titanium, Nickel alloy, njl.njl kwaye iAC yangoku isetyenziselwa ialuminium, ialluminiyam ialloy kunye nemagnesium.Umthombo wamandla uquka i-transformer, isilungisi kunye nolawulo lombane.Ubukhulu becala i-10 - 35 V iyafuneka kwi-5-300 A yangoku ukwenzela ukuveliswa kwe-arc efanelekileyo.

TIG Totshi:

Yeyona nxalenye ibalulekileyo ye-TIG welding.Le totshi inamacandelo amathathu aphambili, i-tungsten electrode, iikholethi kunye nombhobho.Le totshi inokupholiswa ngamanzi okanye ipholiswe ngumoya.Kule totshi, ikholethi isetyenziselwa ukubamba i-electrode ye-tungsten.Ezi zifumaneka kwi-diameter eyahluka-hlukeneyo ngokwe-diameter ye-tungsten electrode.Umbhobho uvumela i-arc kunye neegesi ezikhuselekileyo ukuba zingene kwindawo ye-welding.Icandelo lomnqamlezo wombhobho lincinci elinika i-arc ephezulu.Kukho iipasi zeegesi ezikhuselekileyo emlonyeni.Umlomo we-TIG kufuneka utshintshwe rhoqo ngekhefu ngenxa yokuba uyaphelelwa ngenxa yobukho bentlantsi emandla.

Inkqubo yoBonelelo ngerhasi yokukhusela:

Ngokuqhelekileyo i-argon okanye ezinye iigesi ze-inert zisetyenziswa njengegesi ekhuselekileyo.Injongo ephambili yegesi ekhuselekileyo ukukhusela i-weld kwi-oxidization.Irhasi ekhuselweyo ayivumeli ioksijini ezayo okanye omnye umoya ungene kwindawo edityanisiweyo.Ukukhethwa kwerhasi ye-inert kuxhomekeke kwintsimbi ekufuneka idityaniswe.Kukho inkqubo elawula ukuhamba kwerhasi ekhuselweyo ukuya kwindawo edityanisiweyo.

Izinto zokuSigcwalisa:

Ubukhulu becala ukuwelda amashiti abhityileyo akukho nto yokuzalisa isetyenziswayo.Kodwa kwi-weld eshinyeneyo, kusetyenziswa izinto zokugcwalisa.Izinto zokugcwalisa zisetyenziswa ngohlobo lweentonga ezondla ngokuthe ngqo kwindawo ye-weld ngesandla.

Ukusebenza:

Ukusebenza kwe-TIG welding kunokushwankathelwa ngolu hlobo lulandelayo.

• Okokuqala, i-voltage ephantsi yombane ophezulu unikezelo lwangoku olunikezelwa ngumthombo wamandla kwi-electrode ye-welding okanye i-tungsten electrode.Ikakhulu, i
  I-electrode iqhagamshelwe kwi-terminal engalunganga yomthombo wamandla kunye nomsebenzi kwi-terminal eqinisekileyo.
• Le yangoku ebonelelweyo yenza intlantsi phakathi kwe-tungsten electrode kunye nomsebenzi.I-Tungsten yi-electrode engasetyenziswayo, enika i-arc ebukhali kakhulu.Le arc ivelise ubushushu obunyibilikisa isiseko sesinyithi ukwenza i-welding joint.
• Iigesi ezikhuselekileyo ezifana ne-argon, i-helium inikezelwa ngevalve yoxinzelelo kunye nevalve elawulayo kwitotshi ye-welding.Ezi gesi zenza ikhaka elingavumeli nayiphi na ioksijini kunye nezinye iigesi ezisebenzayo kwindawo ye-weld.Ezi gesi zikwadala iplasma eyonyusa umthamo wobushushu we-arc yombane ngoko yonyusa isakhono sokuwelda.
• Ukuwelda imathiriyeli ebhityileyo akukho ntsimbi yesihluzi efunekayo kodwa ukwenza umdibaniso ongqindilili ezinye izinto ezisetyenziswa ngohlobo lweentonga ezityiswa ngesandla yi-welder kwindawo yokuwelda.

Isicelo:

• Ikakhulu isetyenziselwa ukuwelda ialuminiyam kunye neealloyi zealuminiyam.
• Isetyenziselwa ukuwelda insimbi engenasici, i-carbon base alloy, i-copper base alloy, i-nickel base alloy njl.
• Isetyenziselwa ukuwelda iintsimbi ezahlukeneyo.
• Isetyenziswa kakhulu kwimizi-mveliso ye-aerospace.

Izinto eziluncedo kunye nezingeloncedo:

Izinto eziluncedo:

• I-TIG ibonelela ngokudityaniswa okuqinileyo ngokuthelekisa kunye nekhaka le-arc welding.
• Umdibaniso uxhathisa ngakumbi kwi-corrosion kunye ne-ductile.
• Ukunyaniseka okubanzi koyilo oludibeneyo kunokubumba.
• Ayifuni flux.
• Iyakwazi ukuzenzekelayo ngokulula.
• Le welding ifaneleke kakuhle kumaphepha amancinci.
• Inika umphezulu ogqibeleleyo ukugqiba ngenxa yokuba i-splatter yensimbi engathandabuzekiyo okanye iintlantsi ze-weld ezonakalisa umphezulu.
• Umdibaniso ongenasiphako unokudalwa ngenxa ye-electrode engasetyenziswayo.
• Ulawulo ngakumbi kwi-welding parameter thelekisa nezinye i-welding.
• Zombini i-AC kunye ne-DC yangoku ingasetyenziswa njengonikezelo lwamandla.

Izinto ezingeloncedo:

• Ubungqingqwa bentsimbi ukuba bufakwe kwi-weld bulinganiselwe malunga ne-5 mm.
• Yayifuna umsebenzi wobuchule obuphezulu.
• Iindleko zokuqala okanye zokuseta ziphezulu xa kuthelekiswa ne-arc welding.
• Yinkqubo ye-welding ecothayo.
