Ukusebenzisa i-TIG welding lapho usebenza ne-aluminium

Eng-weld uyazi ukuthi amaphrojekthi ahlukene adinga izindlela namathuluzi ahlukene. Ngale ndlela, ukushisela izinto ezahlukene kudinga ukukhetha amathuluzi afanele ukuze uthole imiphumela oyifunayo. Ukusebenza nge-aluminium kunzima ngenxa ye-conductivity ephezulu kanye nephuzu eliphansi lokuncibilika, kuyilapho ifilimu ene-oxidised endaweni ye-aluminium inephuzu elihlukile lokuncibilika ku-aluminium ngokwayo ngakho-ke ikhohlisa ukusebenza ngisho nakubashiseli abanolwazi.

I-Aluminium ifanele kokubili i-MIG kanye ne-TIG yokushisela, umehluko phakathi kwendlela efaneleke kakhulu uvela ekushubeni kwezinto, ngoba i-MIG yokushisela iyanconywa njengoba ikwazi ukwenza umsebenzi ngokushesha, kuyilapho i-aluminium ezacile i-TIG ifaneleka kakhulu. Kulesi sihloko, u-Eng-Weld uzobe ebheka i-Aluminium TIG welding.

Ezimweni eziningi, i-TIG welding isetshenziswa uma usebenza nge-aluminium. Ngenxa yokulawula okwenyukile onakho uma usebenzisa le ndlela, unamandla okuvimbela i-aluminium ekushiseni ngokweqile.

Ukukhethwa kwenduku yokugcwalisa kuyisici esibucayi se-TIG welding, ukusetshenziswa kwezandla zombili kunikeza i-welder ukulawula okuhle kakhulu, ukukhetha induku yokugcwalisa efana neyensimbi yomzali kubalulekile, njengoba nokuba namandla afanayo okuqina kumzali. insimbi inciphisa amathuba okuqhekeka kwi-weld, kanye nokunciphisa amathuba okuyeka ukushisela. Njengoba ungasebenzisi i-mechanical feeding yokushisela i-TIG, okunye okwaziwa ngokuthi yi-GTAW welding, ususa izinkinga zokuphakela ezivame ukuhlotshaniswa nezindlela zokushisela ezisebenzisa izifunzo zezintambo ezizenzakalelayo.

I-TIG welding, ngenxa yesidingo sokusebenzisa izandla ezimbili ukuze usebenzise kokubili ithoshi yokushisela kanye nezinto zokugcwalisa ngesikhathi esisodwa, kukuphoqa ukuthi uthathe isikhathi esiningi ngakho-ke kuyindlela engcono lapho ikhwalithi nokunaka imininingwane kubalulekile. Njengoba uzondla isigcwalisi ngokwakho, uthola nomsebenzi ongenawo ama-spatter, okuholela ekuqedeni okuhlanzekile. 

Umshini wokushisela we-TIG olungile

Amashisela e-TIG afanele i-aluminium ngokuvamile anezici ezilandelayo:

• Inamandla e-AC, enye indlela yamanje iyenza ifaneleke kakhulu ukubhekana nefilimu ye-oxide endaweni ye-aluminium.
• Ububanzi bamandla okukhiphayo bufika ku-500A emishinini emikhulu ye-TIG.
• I-welding kufanele ibe ne-amperage ephansi, okusho ukuthi ukuzinza kwe-arc akumele kudlule ama-ampere ayi-10.
• Umjikelezo wawo womsebenzi kufanele ube phakathi kuka-50% - 80%, nakuba lokhu kungase kuhluke.

Ukuze uthole ama-welds amancane nanembe kakhudlwana namaphrojekthi ahlanganisa i-aluminium, ukushisela kwe-TIG kufaneleka kangcono ngenxa yokusebenza kwezandla ezimbili. Lokhu kuphoqa umshiseli ukuthi enze izinto ngendlela ethe xaxa futhi asebenze ngejubane eliphansi, okuvumela ukunakekelwa okukhulu, okubalulekile lapho usebenza nge-aluminium encane. Le ndlela iphinde ikhiqize isiphetho esihlanzekile nesishelelayo njengoba kufanele ingabi nasici ngenkathi iqinisekisa ukuthi ilunga elithembekile lenziwa. Kodwa-ke, le ndlela edla isikhathi esiningi, ehambisana nokukhuphuka kwezindleko zezinto zokwakha kanye nemishini kwenza lokhu kube indlela ebiza kakhulu yokushisela i-aluminium. 

Kunomehluko omkhulu phakathi kwe-MIG ne-TIG yokushisela, ikakhulukazi uma usebenza nge-aluminium. Indlela ngayinye inezinkinga zayo kanye nezinzuzo zayo.

Ukushisela kwe-TIG kungawufanelekela kangcono umsebenzi wakho wokushisela i-aluminium uma:

• Ukushisela kwakho kudinga ukujabulisa ngobuhle futhi kunikeze isiphetho esihle, lokhu kufinyelelwa ngobuhlalu bokushisela obufanayo.
• Kudingeka ukunaka okukhulu emininingwaneni.
• Umsebenzi wakho kufanele ungabi ne-spatter, okuholela ekuqedeni okuhlanzekile.
• Indawo yakho yokusebenza ihlanzeke ngokwedlulele.
• Amaphrojekthi amancane ngaphakathi nature.
• I-weld ayibandakanyi insimbi ekhonjiwe.
• Ufisa ukuba nokulawula okwengeziwe phezu kwe-weld yakho.
• Kudingeka amashisela aqinile.
• Kudingeka ukulungiswa okuncane, njengalapho kushiselwa i-MIG, akukho ukusetshenzwa kwesihlabathi noma ukuhlanza okudingekayo phakathi kwemisebenzi.

Amagesi Asetshenziswayo 

Ngesikhathi sokushisela kwe-TIG, amagesi angenayo asetshenziswa ukuze kuvikelwe i-weld pool ezintweni ezingcolisa ezifana nomswakama, ezinemithelela eyingozi ekuthembekeni kwe-weld. Ngokuvamile, lapho usebenza nge-aluminium, i-Argon gas isetshenziswa. 

Njengegesi engasebenzi, ehloniphekile, ayinambala, ayinaphunga, futhi okubaluleke kakhulu ngokombono womshiseli, iyigesi engasebenzisi amakhemikhali. Lokhu kusho ukuthi i-aluminium encibilikisiwe ngeke isabele ngegesi evikelayo, iqinisekise ukuthi i-weld ihlala imsulwa. 

Nakuba kufanele kuqashelwe ukuthi i-Argon ivame ukuhlanganiswa ne-Helium, i-Hydrogen ne-Carbon Dioxide, njengoba ingxube inganikeza izakhiwo ezithile i-Argon yedwa engakwazi. Isibonelo, ngokuhlanganisa i-Argon ne-Helium, i-welder iyakwazi ukuzuza ukungena okujulile, kuyilapho iqinisekisa ukuthi i-weld pool ihlala imanzi. Ukwengezwa kweHydrojeni kuzonikeza umphumela ofanayo nalowo ozuzwe ngokusebenzisa i-Helium, kodwa enamandla kakhulu. 

Isihluthulelo siwukusebenzisa amagesi angenayo i-oxidising, njengoba lezi zizobhubhisa i-electrode ye-tungsten. 

I-TIG Welding kanye ne-Tungsten Electrodes

Ukukhetha umshini wokushisela we-TIG ofanele kudinga ukuba ucabangele ngokucophelela umsebenzi osuwenzile, kanye nezinye izinto eziguquguqukayo, njengokusebenzisa i-alternating noma yamanje eqondile, futhi kunengqondo efanayo lapho kukhethwa i-electrode ye-tungsten efanele. 

Kumelwe ucabange ukuthi akuzona zonke izinhlobo zama-electrode ezifanele ukusetshenziswa ne-alternating current, i-current predominant esetshenziswa uma kushiselwa i-TIG nokusebenza nge-aluminium, kodwa kunezinye izici okufanele zicatshangelwe. Umsebenzi othize uzoba nomkhulu umthelela ekukhethweni kwe-electrode ye-tungsten efanele, njengoba ungakhetha ku-tungsten ehlanzekile noma i-tungsten enezithako ze-oxidic, eziletha izakhiwo ezahlukene. 

I-Zirconium oxide (ZrO2) inika amandla i-arc ezinze kakhulu uma iqhathaniswa ne-tungsten emsulwa, konke ngenkathi yehlisa ukuhwamuka, kuyilapho i-Cerium oxide inika i-tungsten enhle kakhulu yokuthungela kanye nezakhiwo zokubusa. I-Lanthanum oxide nayo inezindawo ezinhle kakhulu zokuthungela, kuyilapho inenzuzo eyengeziwe yokwandisa impilo yesevisi ye-electrode. I-tungsten ehlanzekile okwamanje, inika amandla i-arc ezinzile kodwa ayinawo amandla okuthwala afanayo amanje, ukuthungela kalula noma impilo ende yesevisi enawo ama-electrode anezithasiselo ze-oxidic.

I-TIG yokushisela ifaneleka kakhulu kubashiseli abanolwazi olunzulu nalabo abadinga ukushiselwa okucocekile.
