Umehluko Phakathi kwe-MIG ne-TIG Welding

Izindlela zokushisela ze-MIG ne-TIG zijoyina izinsimbi ngokusebenzisa i-arc kagesi kanye negesi evikelayo eyenza ukushisela. Nakuba afana ngezindlela eziningi, anezici eziwahlukanisayo. Njengoba ngayinye yalezi zindlela inobuhle nobubi bayo, kubalulekile ukuthi ube nalo lonke ulwazi ngaphambi kokunquma ukuthi iyiphi indlela ozoyisebenzisa.

Lesi sihloko sizogqamisa umehluko omkhulu phakathi kwezindlela zokushisela ze-MIG ne-TIG. Ukwengeza, izoxoxa ngezinzuzo nezingozi zabo.

Kuyini ukushisela kwe-MIG?

Igesi ye-inert yensimbi ukushisela kubizwa nangokuthi i-gas metal arc welding (GMAW). Le nqubo isebenzisa i-semi-automatic noma i-arc ezenzakalelayo ngokuphelele ukuze ikhiqize i-weld ngento esetshenziswayo yokugcwalisa i-electrode. Iphinde isebenzise igesi evikelayo ukuze ivikele i-weld, ithuthukise ukungena kwe-weld, futhi inciphise ubuhlalu be-weld porosity.

Igesi evikelayo kanye ne-electrode kufakwa ngaphakathi ithoshi yokushisela noma isibhamu. Inhlanganisela yegesi evikelayo ihlanganisa u-75% we-argon no-25% we-carbon dioxide. Ezinye izingxube zingasetshenziswa kuye ngezinto zenqubo yokushisela nezinye izinto eziguquguqukayo ezifana nobukhulu nobukhulu bezinto zokusebenza. Ububanzi be-electrode yezintambo ezisetshenziswayo eziqhubekayo buyahlukahluka kuye ngezinhlobo zensimbi ezihlanganiswayo, ukumiswa kwamalungu, kanye nogqinsi lwengxenye. I-electrode ifakwa endaweni yokushisela ngesivinini esinqunywa izilungiselelo zesivinini sokuphakela kwezintambo (WFS) ukuze kunikeze ukushisela okwanele ukujoyina insimbi.

– Abashiselayo badinga ukuvikeleka entuthwini

Kuyini ukushisela kwe-TIG?

Igesi ye-inert ye-Tungsten ukushisela kubizwa nangokuthi i-gas tungsten arc welding (GTAW). Inqubo isebenzisa i-arc kanye ne-electrode ye-tungsten engadleki kanye nento ehlukile yokugcwalisa esebenzisekayo. Lesi sigcwalisi siyinduku efakwa ngesandla echibini lokushisela; ngaleyo ndlela zombili izandla zisetshenziswa, lapho eyodwa ibambe i-tungsten kanti enye, induku yokugcwalisa.

I-weld eyenziwayo inquma ukubunjwa nobukhulu benduku yokugcwalisa. Inqubo yokushisela ye-TIG isebenzisa igesi evikelayo engu-100% argon. I-carbon dioxide ayisetshenziswa ngoba iholela ukudinwa ukwakheka kwe-oxide, okugqoka ngaphambi kwesikhathi i-electrode futhi kungcolise i-weld. Le nqubo futhi idinga i-foot pedal ukuze opharetha alawule i-amperage futhi alungise ukushisa ngesikhathi sokushisela.

buhle

- Ama-welds ahlukahlukene akwazi ukuhlanganisa uhla olubanzi lwezinsimbi ezincane nezincane

- Izinsimbi eziqinile, ezithandekayo, nezinembe kakhulu

- Impahla yokugcwalisa inketho

bawo

- Ihamba kancane ngenxa yomsebenzi wokulungiselela owengeziwe, ukwandisa izikhathi zokukhiqiza

- Inqubo ebizayo njengoba idinga izingxenye eziningi nesikhathi

- Kunzima ukufunda ukuletha i-weld enembile futhi enembile

Umehluko phakathi kwe-MIG ne-TIG yokushisela

I-1. Izindleko

Uma kubhekwa izindleko ngonyawo ngalunye lobuhlalu, ukushisela kwe-TIG kubiza ngaphezu kokushisela kwe-MIG. Kunamazinga aphansi e-deposit kumashisela e-TIG adinga ama-opharetha anolwazi kakhudlwana, okuyizindleko ezinkulu ukuwaqasha. Le nqubo idinga nomsebenzi owengeziwe wokulungiselela, ophakamisa inani lezindleko. Ukwengeza, izinto zokushisela ze-MIG kanye nemishini ivame ukubiza kancane kune-TIG. Zonke lezi zici zibonisa ukuthi ukushisela kwe-TIG kubiza kakhulu uma kuqhathaniswa nokushisela kwe-MIG.

2. Ijubane

Izishicileli ezipholile emoyeni ze-MIG ziphakela izinto zokugcwalisa ngokuzenzakalelayo ku-weld pool futhi zine-arc ebanzi neyindilinga eqeda ukushisa kalula. Ngenxa yalokho, ama-opharetha ahambisa i-weld puddle ngokushesha kuyilapho benza ama-run amade ngaphandle kokushisa ngokweqile.

Ngakolunye uhlangothi, abashiseli be-TIG abakwazi ukuhlinzeka ngezinduku zokugcwalisa ezanele ukuze baphume ngesivinini se-MIG njengoba bengakwazi ukuhambisa i-weld puddle ngokushesha. Futhi, amathoshi apholile emoyeni ku-TIG welding ngokuvamile ashisa kakhulu phakathi nokugijima isikhathi eside. Ngokujwayelekile, zidinga ukupholisa noma ukushintshaniswa ngamathoshi abiza kakhulu apholile ngamanzi.

3. Izinto ezisebenzayo

Kunomehluko omncane phakathi kwe-TIG ne-MIG uma kuziwa ekukhetheni izinto ezibonakalayo. Zombili izindlela zokushisela i-arc zifanele uhla olubanzi lwezinsimbi njenge-carbon steel, i-aluminium, nensimbi engagqwali. Nokho, ukushisela kwe-TIG kusebenza kangcono ngezinsimbi ezincane, kuyilapho ukushisela kwe-MIG kulungele izinsimbi eziwugqinsi. Ukwengeza, i-TIG welding inikeza ukulawula okungcono kokusebenza, okunciphisa ukucekelwa phansi kwendawo yokusebenza.

4. Amandla e-weld

Amashisela e-TIG anamandla kunalawo akhiqizwa ukushisela kwe-MIG. Lokhu kungenxa yokuthi abashiseli be-TIG benza i-arc encane futhi egxilile enikeza ukungena okungcono ensimbi. Futhi, ubuhlalu bokushisela be-TIG, uma busetshenziswe ngendlela efanele, buqukethe izimbobo ezimbalwa kanye nokunye okungalungile okungase kunciphise ukushisela.

Noma kunjalo, ukushisela kwe-MIG kungakha amashisela aqinile anokungena kahle kwensimbi ngokusika noma ukugaya umsele omise okwe-V ungene ekuhlanganyeleni. Lokhu kufanele kwenziwe ngaphambi kokuqala inqubo yokushisela ukuze kuthuthukiswe ukungena. Ukwengeza, umthengi angakwazi ukusebenzisa isivinini esihle sokuhamba kanye nethoshi ukuze athuthukise amandla okushisela kwe-MIG.

5. Ubunzima benqubo

Inqubo yokushisela i-MIG kulula ukuyifunda esikhundleni sokushisela i-TIG. Lokhu kungenxa yokuthi ukushisela kwe-TIG kuhilela ukusetshenziswa kwezandla ezimbili, lapho enye ihambisa ithoshi yokushisela kanti enye iphakela induku yokugcwalisa echibini lokushisela. Ngaphezu kwalokho, kukhona i-foot pedal esetshenziselwa ukulawula i-amperage. Konke lokhu kunyakaza kudinga ukuvumelanisa ukuze kuzuzwe ukushisela okufunayo futhi ngaleyo ndlela kungase kube nzima ukukwazi kahle.

I-TIG iyinqubo yokushisela ethuthuke kakhulu njengoba izinsimbi ezihlanganisiwe kufanele zihlanzwe futhi zilungiswe kahle ukuze kwenziwe inqubo. Ngokuphambene, i-MIG welding kulula ukuyiqonda. Ayikho i-foot pedal yokulawula futhi impahla yokugcwalisa ifakwe ngokuzenzakalelayo kusibhamu sokushisela, okudinga isandla esisodwa kuphela ukudala i-weld.

6. I-Electrode

The i-electrode esetshenziswa ku-MIG noma ku-TIG iyahluka. Inqubo yokushisela ye-MIG isebenzisa i-electrode yocingo esetshenziswa ngokuqhubekayo lapho ihlanganisa izingcezu ezimbili zensimbi. I-TIG, ngakolunye uhlangothi, isebenzisa i-electrode ye-tungsten engadleki kanye nensimbi yokugcwalisa ehlukile. Ngenxa yalokho, abathengi bazosebenzisa isandla esisodwa ukwenza ukushisela kwe-MIG ngokuphambene ne-TIG, ukushisela lapho kudingeka babe nesandla esisodwa phezu kwethoshi kanye nesinye ezintweni zokugcwalisa.

7. Umthombo wamandla

Ku-MIG welding, umthombo wamanje (DC) oqondile usetshenziselwa ukudala ukuzinza ku-arc kagesi. Amandla aphinde anikeze ukungena okwanele kwezinsimbi. Ngokuphambene, ukushisela kwe-TIG kunikeza ukuguquguquka okuningi njengoba kungadonsa amandla kokubili emithonjeni yamandla ashintshayo (AC) kanye namanje aqondile (DC). Nokho, ukukhethwa amandla kuncike izinsimbi ukushisela, inani le-spatter echibini lokushisela, kanye ne-arc kagesi oyifunayo.

8. I-Weld aesthetics

Amashisela e-TIG abonisa izimfanelo zobuhle ezingcono kakhulu uma kuqhathaniswa nokushisela kwe-MIG. Amashisela e-TIG ane-spatter encane noma awanayo nhlobo edinga kuphela ukupholisha ukukhanya ukuze kuqedelwe futhi kususwe ukuguquguquka kombala. Isibonelo, izinhlamvu zemali ezishiselwe ze-TIG zenziwa ngendlela yokushisela ejabulisa kakhulu futhi zingasetshenziswa ukwenza amashisela angapendiwe abukeke kangcono.

Ngokuphambene, ama-MIG weld awafiseleki kangako ekubukekeni. Kudinga abashiseli abanolwazi ukuze bakhe ubuhlalu bokushisela obubukekayo be-MIG. Ukushisela kwe-MIG kulungile ezinhlelweni lapho ukubukeka kungathathwa njengokubaluleke kangako. Ukwengeza, i-aesthetics ayidingeki lapho ama-welds kufanele ahlanganiswe ukuze amboze ukubukeka kwejoyinti.

Isiphetho

Ngokusobala, kokubili i-MIG kanye ne-TIG kungabhekwa kangcono kunomunye njengoba kokubili izinqubo zokushisela zinezinzuzo kanye nokubi ngokusekelwe esimweni sokufaka isicelo. I-MIG ngokuvamile kulula ukuyifunda futhi iyashesha kuyilapho i-TIG ithathwa njengokukhiqiza amashisela ekhwalithi ephezulu. Noma kunjalo, zombili izimo zingase zibe nokuhlukile futhi ukukhetha komthengi kuncike emisebenzini eyenziwa. Abathengi kufanele babe namaphrojekthi engqondweni futhi bacabangele izici ezimbalwa njengezindleko, uhlobo lwempahla, okokusebenza, kanye nezidingo zangemuva kokucubungula ukuze benze izinqumo zokushisela ezinolwazi.
