Uma kukhulunywa ngokuhlanganiswa kwethusi, ukunemba akuyona nje into enhle ukuba nayo—kuyisici sokwakheka noma ukuqeda ukuqina komkhiqizo, ukusebenza kahle, kanye nobuhle. Kungakhathaliseki ukuthi wenza izingxenye ze-HVAC, izixhumi zikagesi, noma izinto zokuhlobisa zethusi, indlela yokushisela engafanele ingaholela emithungweni enezimbobo, ukulahlekelwa yi-zinc, noma ukuqedwa okungathandeki okuphazamisa amaphrojekthi akho. Uma ubhekene nemiphumela engaguquki evela kumasu endabuko okushisela ithusi, sekuyisikhathi sokubheka ngale kwezisekelo: ukushisela i-TIG kungaba yisisombululo obusifuna.
Okokuqala, ake sihlaziye izinto ezibalulekile ze-Brass Welding ukuze siqale isiteji. I-Brass, ingxubevange yethusi ne-zinc, iyaziswa kuzo zonke izimboni ngenxa yokushisa kwayo okuhle kakhulu, ukumelana nokugqwala, kanye nokuguquguquka—kodwa lezi zakhiwo ezifanayo zenza kube nzima ukushisela. Ngokungafani nensimbi, ithusi linephuzu eliphansi lokubilisa le-zinc (907°C) elingaphansi kwephuzu lokuncibilika kwethusi (1083°C), okusho ukuthi ukushisa ngokweqile ngesikhathi sokushisela kungabangela i-zinc ukuba iphele. Lokhu akugcini nje ngokwenza buthaka ama-weld kodwa futhi kukhiqiza umusi onobuthi, okwengeza izingozi zokuphepha enkambisweni. Ngaphezu kwalokho, ukushisa okuphezulu kwethusi kusho ukuthi ukushisa kuyanyamalala ngokushesha, okwenza kube nzima ukugcina ichibi lokushisela elizinzile ngezindlela ezingacacile.
Iukushisela ngethusiImboni idinga izixazululo ezilinganisela ukusebenza kahle nekhwalithi, ikakhulukazi emikhakheni efana nezimoto, izindiza, kanye namapayipi lapho izingxenye kufanele zihlangabezane nezindinganiso zokuphepha eziqinile kanye nokusebenza. Ekukhiqizweni okuphezulu, ukuhambisana kubalulekile—ukwehluka kwe-batch kuya ku-batch emandleni noma ekubukekeni kwe-weld kungaholela ekubuyiselweni okubizayo noma ekubuyiselweni komkhiqizo. Ngomsebenzi owenziwe ngokwezifiso noma wokuhlobisa, ukuqeda ubuhle kuthatha indawo ephambili; i-weld engcolile ingonakalisa ukubukeka kwezinto zethusi, izinsimbi zomculo, noma imininingwane yokwakha. Lezi zidingo zemboni zichaza ukuthi kungani ochwepheshe abaningi bephendukela ku-TIG welding ukuze bajoyine ithusi ngokunemba.
Ngakho-ke, kungani ukushisela kwe-TIG (okwaziwa nangokuthi i-Gas Tungsten Arc Welding, GTAW) kufanelekela ngokukhethekile ukushisela kwe-Brass? Ake siqale ngokunemba kwayo okungenakuqhathaniswa. I-TIG isebenzisa i-electrode ye-tungsten engasebenziseki kanye ne-foot pedal yokulawula i-amperage, okuvumela abashisela ukuthi balungise ukufakwa kokushisa ngokunemba okumangalisayo. Leli zinga lokulawula libalulekile kuthusi: livimbela ukushisa ngokweqile, linciphisa ukuhwamuka kwe-zinc, futhi linciphisa ingozi ye-porosity—amaphutha avamile kwezinye izindlela zokushisela njenge-MIG noma ukushisela kwegesi. Kumashidi ethusi amancane noma amashubhu amancane (avamile ezinhlelweni ze-elekthronikhi neze-HVAC), ikhono lokufaka ukushisa okuphansi kwe-TIG ligwema nokugoba, ligcina isimo sokuqala kanye nobuqotho bezinto.
Enye inzuzo enkulu yokushisela i-TIG yokuhlanganisa ithusi ukuthi ihlanzekile, ayinayo i-slag. Ngokungafani nokushisela okunamathelayo, i-TIG ayidingi i-flux, okususa isidingo sokuhlanza ngemva kokushisela ukuze kususwe izinsalela ze-slag—okonga isikhathi esikhulu ezindaweni zokusebenzela ezimatasa. Igesi yokuvikela engasebenzi (ngokuvamile i-argon noma ingxube ye-argon-helium) esetshenziswa ekushiseleni i-TIG iphinde ivikele ichibi lokushisela ekungcolisweni komoya, ivimbele i-oxidation futhi iqinisekise umthungo obushelelezi, ofanayo oqinile futhi okhangayo ngokubonakalayo. Lokhu kushintsha umdlalo womsebenzi wethusi wokuhlobisa noma izingxenye lapho ukumelana nokugqwala kungaxoxiswana khona, njengezingxenye zasolwandle noma zamapayipi.
Ukuphepha kungenye indawo lapho i-TIG ikhanya khona ngokushisela ithusi. Nakuba zonke izindlela zokushisela ithusi zinengozi yokuchayeka ku-zinc fume, ukulawula ukushisa okunembile kwe-TIG kunciphisa inani lokushiswa yi-zinc uma kuqhathaniswa nezindlela zokushisa okuphezulu njengokushisela i-oxyacetylene. Uma kuhlanganiswe nomoya ofanele kanye nemishini yokuzivikela yomuntu siqu (i-PPE), i-TIG idala indawo yokusebenza ephephile—okuyinto eza kuqala kumabhizinisi afuna ukuhambisana nemithetho ye-OSHA kanye ne-HSE. Ngaphezu kwalokho, ukushisela i-TIG akukhiqizi spark noma ukuchitheka, kunciphisa izingozi zomlilo ezindaweni zokusebenzela ngezinto ezivuthayo.
Kuyaphawuleka ukuthi ukushisela i-TIG akuyona ikhambi elifanelana nosayizi owodwa, kodwa ukuguquguquka kwayo kuyenza ivumelane nezidingo eziningi zokuhlanganisa ithusi ngokunemba. Isebenza kokubili ngama-alloy ethusi aphansi (alpha) kanye ne-high-zinc (alpha-beta), futhi ingaphatha ubukhulu obuvela kuma-gauge amancane (ngaphansi kuka-1.5mm) kuya ku-9mm ngezinto zokugcwalisa ezifanele. Kuma-brasses ane-zinc ephezulu, ukusebenzisa induku yokugcwalisa engenazinc kanye negesi yokuvikela egcwele i-helium kunciphisa kakhulu ukukhiqizwa komusi kanye nokumbozwa, kuqinisekisa ukushisela okuqinile nokuthembekile.
Kubathengi kanye nabakhi abahlola izinketho zokushisela ngethusi, isinqumo ekugcineni sincike ezintweni eziza kuqala kuwe. Uma udinga isivinini ngaphezu kwakho konke okunye, ukushisela nge-MIG kungase kufanelane nezingxenye zethusi ezijiyile. Kodwa uma ukunemba, ukuhambisana, kanye nekhwalithi kungaxoxiswana ngakho—ikakhulukazi ngezicelo ezibucayi noma ezinhle—ukushisela nge-TIG kuyindlela ecacile. Kubhekana nezinselele ezihlukile zethusi njengento, kuhlangabezana nezindinganiso eziqinile zezimboni ezibalulekile, futhi kuletha imiphumela enciphisa ukusebenza kabusha futhi kuthuthukise inani lomkhiqizo wokugcina.
Ezweni lokuhlanganisa ithusi ngokunemba, ukusika amakhona ngezindlela eziyisisekelo zokushisela kuvame ukuholela ezinkingeni eziningi kamuva. Ukushisela i-TIG akuyona nje isinyathelo esisuka kumasu endabuko—kuwukutshala imali ekhwalithini okuholela ekusebenzeni okungcono, ukusebenza okuphephile, kanye namakhasimende ajabule. Kungakhathaliseki ukuthi ungumenzi wezinto onolwazi noma usaqala ukusebenza ngethusi, ukushintshela ku-TIG kungaba umehluko phakathi kwemiphumela emihle nemihle.
