Abashiseli be-TIG, ababizwa nangokuthi ama-tungsten anert gas welders, basebenzisa ama-electrode e-tungsten angasebenziseki ukuze akhiqize i-weld ensimbi. Lawa mashisela ahlukahlukene njengoba ehambisana nokushisela izinhlobonhlobo zezinsimbi, okuhlanganisa i-aluminium, ithusi, ithusi, i-magnesium, insimbi engagqwali, negolide, phakathi kwezinye izinsimbi. Njengoba abashiseli be-TIG sebevamile, le mishini itholakala kalula.
Ukwazi ukuthi yikuphi phakathi kwezinketho ezifanele izinhlelo zokusebenza ezahlukene zokushisela kungaba inselele. Ngakho-ke, lesi sihloko sizohlola izici ezibalulekile okufanele uzicabangele ngenkathi ukhetha i-TIG welder. Izophinde ibheke izinhlobo ezahlukene zamashiseli e-TIG atholakalayo ukuze asize abathengi ukuthi bathole okufanelana nezidingo zabo kangcono.

Isiphetho
Uhlolojikelele lwemakethe yomhlaba wonke ye-TIG welders
Imakethe yokushisela ye-TIG yomhlaba wonke ifanelekile US $ 13 billion futhi kulindeleke ukuthi ifinyelele ku-US$ 25 billion ngo-2032, ikhula ngezinga lokukhula elihlanganisiwe lonyaka (CAGR) lika-6.7%. Ukukhula kwemakethe kugqugquzelwa yisidingo semishini yokushisela evela emikhakheni eyahlukene yezimboni, okuhlanganisa izimboni zezimoto, i-aerospace, ezokuthutha, nezimboni zikawoyela negesi.
Isidingo somthengi sokushisela izinsimbi ezingavamile ezinobukhulu obuhlukene siholele ekukhuleni kosayizi wemakethe yama-welders we-TIG. Njengoba bekhiqiza ukushisela okunembe kakhudlwana nasezingeni eliphezulu, abaningi bakhetha ukushisela igesi ye-tungsten inert kunemishini yokushisela izinti.
Amathiphu okukhetha abashiseli be-TIG
Izinga le-amperage
Lapho uthenga i- TIG welder, cabangela izinga le-amperage. Kungamandla kagesi asuka emshinini wokushisela okalwa ngama-ampere. Imishini enamazinga aphansi e-amperage inikeza ukuzinza okuhle kwe-arc ekuqaleni nokuqedela ama-welds.
Amashisela e-TIG asezingeni eliphansi afanele izinsimbi ezincane ngoba angakhiqiza amashisela aqinile ngaphandle kokuwashisa. Ngakolunye uhlangothi, abashiseli bezinga eliphakeme le-amperage bafanele ochwepheshe abasebenza ngezinsimbi eziwugqinsi.
I-AC ne-DC welding
Ngaphambi kokutshala imali ku-welder ye-TIG, kubalulekile ukucabangela izinketho zayo zamanje. Amashisela atholakalayo ahlinzeka ngenketho ye-DC noma enye i-DC/AC. Lezi zinketho zincike ohlotsheni lwensimbi ezingashisela ngalo kahle.
Isibonelo, ukushisela i-DC TIG kufanelekile uma kushiselwa izinsimbi ezivamile njengensimbi. Lapho usebenza ngezinsimbi ezilula neziqinile njenge-aluminium, a Umshini we-DC/AC ifanela inhloso ngendlela efanele.
Izilawuli ezifanele
Ukuhlola izilawuli ze-welder nakho kubalulekile ngenkathi uthenga isishiseli esithembekile se-TIG. Le mishini yakhelwe nge-foot pedal esiza ukulungisa izinga le-amperage. Kuba lula ukulawula ukunemba kwe-welding kanye nekhwalithi yokugcina ngokulawula izinga le-amperage.
Ngakho-ke, abathengi kufanele bahlole izilawuli futhi baqinisekise ukuthi ziqinile futhi zivikelekile ngomshini. Ukuhlola kahle i-welder kugwema ukulimaza i-weld lapho uthinta isilawuli esingalungile. Ukuhlola imininingwane ebalulekile njengezilawuli eziqinile nezilungile kuqinisekisa inqubo yokushisela ebushelelezi ngaphandle kokuyekethisa ikhwalithi yomphumela wokugcina.
Ukusebenza kwe-welding ephansi
Ukuhlola ukusebenza komshiseli ku-amperage ephansi kubalulekile ngaphambi kokuthenga. Imishini ene-amperage ephansi inganikeza ama-arcs azinze kakhulu. Futhi, banikeza isiqalo se-weld esilula, ukulawula ikhwalithi engcono ye-weld, kanye nomthamo omuhle kakhulu wokugcwalisa i-crater.
Ama-welders ane-amperage ephansi zinokwethenjelwa lapho usebenza ngezinsimbi ezincane. Ngokuphambene, ama-welders aphezulu asebenza kabi ezinsimbi ezincane. Akhiqiza ama-weld arcs aqinile angathungela futhi alimaze insimbi.
Ukuzinza kwe-arc ku-amperage ephansi nakho kuyadingeka ukuze kuqedelwe ukushisela. Isibonelo, i-concave enkulu ingase yakheke lapho kushiselwa i-aluminium, engase iqhekeke ngemva kokuphola kwe-weld. I-low amperage welding yakha i-concave encane ukunciphisa amathuba okuqhekeka lapho i-welding iphola.
Izinketho ze-Plasma cutter kanye ne-stick welding
Abathengi kufanele futhi bacabangele ukufuna i-tungsten inert gas welder enezici ezengeziwe. Ukuba nezici ezengeziwe kumshini wokushisela kuvumela ukufezwa kwemisebenzi eminingi emshinini owodwa. Ngokwesibonelo, a umshini wokufaka insimbi enikeza izici zokusika i-plasma nezici zokushisela izinduku kwenza insimbi isebenze umsebenzi ongenazihibe.
I-TIG welder ingasebenzisa i-electrode ye-tungsten ukuze inikeze kokubili izinzuzo zokusika i-plasma kanye nokushisela izingcezu zensimbi ezisikiwe ndawonye. I-stick welder iba enye indlela yokushisela i-TIG uma kudingeka inketho yokusekelayo. Ukwengeza, ukuba ne-a I-welder ehlukahlukene yonga ezindlekweni zokuthenga imishini ehlukene kanye namandla azowasebenzisa ngokuphelele.
Power
Kubalulekile ukucabangela inani lamandla i-welder edinga ukusebenza. Kuya ohlotsheni lwensimbi olushiselwayo. Isibonelo, i-aluminium, i-magnesium, nama-alloys amaningi ensimbi zisebenzisa ama-welders anamandla aphezulu. Insimbi emaphakathi nensimbi engagqwali zidinga ukusebenzisa imishini yokushisela enamandla aphansi.
Inani lamandla ongakhetha nalo lincike kusayizi wesitolo. Izitolo ezincane ezenza i-welding encane zingase zifune ukusebenzisa i-welder edla amandla amancane. Izitolo ezinkulu zokushisela zingakhetha umshini osebenzisa amandla aphezulu.
Ukuqina kwensimbi nakho kunquma ukuthi yimuphi umshini wokushisela ongawuthola. Ezinsimbi eziwugqinsi, i-TIG welder enamandla amakhulu ifanelekile. Izinsimbi ezizacile zilungile ukusebenza ngemishini edla amandla amancane.
Izinhlobo zokushisela ze-TIG
AC/DC TIG welder
Amashisela e-AC/DC TIG ayimishini eguquguqukayo engashintsha yamanje kuye ngensimbi esebenza kuyo. Ziletha ukusebenza okuthembekile nokungaguquguquki futhi zingasetshenziselwa izinhlelo zokusebenza ezihlukahlukene, okuhlanganisa umsebenzi wamapayipi, umsebenzi ohlanganyelwe, nokulungiswa kwezimoto.
Ukushisela i-AC kusetshenziselwa ukushisela i-aluminium ne-magnesium kuyilapho i-DC isetshenziselwa insimbi emnene nensimbi engagqwali. Ama-welders e-AC/DC anikeza izilungiselelo zamanje eziguquguqukayo, izilungiselelo zemithambeka phezulu/phansi, i-pedal yonyawo, nezilawuli zesikhathi eziningana, okuvumela abashiseli ukuba benze ama-welds ahlukahlukene futhi basebenze ezinhlotsheni ezahlukene zezinsimbi.

- Ukwakheka kwama-crater amaningi kakhulu kuholela ekuqhekekeni kokushisela lapho kuphola.
I-Pulse TIG welder
Lezi zithuthuke kakhulu kwezobuchwepheshe Imishini yokushisela ye-TIG kushintshana phakathi kwamandla aphezulu naphansi, okunikeza abashisela ukulawula okwengeziwe nokunemba ngenkathi beshisela izinsimbi.
buhle
- Angakwazi ukukhiqiza ama-welds ahlanzekile futhi anembile ngisho nasezindaweni okunzima ukufinyelela kuzo.
- Bakhiqiza ama-welds ngokushesha ngenxa yekhono labo lokulawula ngokunembile ubude nokwakheka kwe-arc yokushisela.
– Awonga kakhulu amandla.
bawo
- Abiza kakhulu kunezindlela zendabuko zokushisela.
- Kudinga ikhono eliphezulu lokuzisebenzisa ngendlela efanele.
- Akhiqiza ukushisa okunamandla futhi akhiqize amagesi amaningi angaba yingozi kanye nentuthu. Ngakho-ke, badinga izinyathelo ezifanele zokuphepha okufanele zithathwe lapho bezisebenzisa.
Isiphetho
Abashiseli be-TIG bahlinzeka ngokushisela okunembile nokunembile uma kuqhathaniswa nabashiseli bendabuko. Uma ukukhetha i-welder efanelekile kuyinselele, amabhizinisi angalandela amathiphu angenhla okwenza isinqumo esifundisiwe. Ngakho-ke kufanele babe nesikhathi esilula sokukhetha i-welder ye-TIG enikeza ama-welds ekhwalithi futhi aqinile.
