Xa kufikwa ekudibaniseni ithusi, ukuchaneka akusiyonto imnandi nje ukuba nayo—yinto yokwenziwa okanye yokuyiqhekeza ukuze imveliso ihlale ixesha elide, isebenze kakuhle, kwaye ibukeke kakuhle. Nokuba wenza izinto ze-HVAC, izihlanganisi zombane, okanye izixhobo zobhedu zokuhombisa, indlela engalunganga yokuwelda inokukhokelela kwimithungo eneembobo, ukulahleka kwe-zinc, okanye ukugqitywa okungathandekiyo okubangela ukuba iiprojekthi zakho zingaphumeleli. Ukuba ujongene neziphumo ezingahambelaniyo kwiindlela zemveli zokuwelda ithusi, lixesha lokujonga ngaphaya kweziseko: ukuwelda i-TIG kusenokuba sisisombululo obusikhangela.
Okokuqala, masihlalutye izinto ezibalulekileyo zeBrass Welding ukuze silungiselele inqanaba. Ibrass, i-alloy ye-copper kunye ne-zinc, ixatyiswa kakhulu kumashishini ngenxa yokuqhuba kwayo kakuhle kobushushu, ukumelana nokugqwala, kunye nokuguquguquka—kodwa ezi mpawu zenza kube nzima ukuyihlanganisa. Ngokungafaniyo nentsimbi, ibrass ine-zinc esezantsi yokubila (907°C) ephantsi kune-copper's melting point (1083°C), oko kuthetha ukuba ukufudumala ngexesha lokuhlanganisa kunokubangela ukuba i-zinc iphele. Oku akugcini nje ngokwenza buthathaka ii-welds kodwa kukwavelisa umsi onobuthi, kongeza iingozi zokhuseleko kwinkqubo. Ukongeza, ukuqhuba okuphezulu kobushushu bebrass kuthetha ukuba ubushushu buphela ngokukhawuleza, okwenza kube nzima ukugcina ichibi elizinzileyo le-weld ngeendlela ezingachanekanga kangako.
Iukuwelda ngobheduIshishini lifuna izisombululo ezilungelelanisa ukusebenza kakuhle nomgangatho, ingakumbi kumacandelo afana neemoto, i-aerospace, kunye ne-plumbing apho izixhobo kufuneka zihlangabezane nemigangatho yokhuseleko engqongqo kunye nokusebenza. Kwimveliso ephezulu, ukuhambelana kubalulekile—ukutshintsha kwe-batch-to-batch kumandla okanye imbonakalo ye-weld kunokukhokelela ekusetyenzisweni kwakhona okubiza kakhulu okanye ekubuyiselweni kwemveliso. Kumsebenzi owenziwe ngokwezifiso okanye wokuhombisa, ukugqitywa kobuhle kuthatha indawo ephambili; i-weld engcolileyo inokonakalisa ukukhangeka okubonakalayo kwezinto zobhedu, izixhobo zomculo, okanye iinkcukacha zokwakha. Ezi mfuno zoshishino zichaza ukuba kutheni iingcali ezininzi zijika kwi-TIG welding ukuze zidibanise ngokuchanekileyo i-brass.
Ngoko ke, kutheni i-TIG welding (ekwaziwa ngokuba yi-Gas Tungsten Arc Welding, GTAW) ifanelekile ngokukodwa kwi-Brass Welding? Masiqale ngokuchaneka kwayo okungenakuthelekiswa nanto. I-TIG isebenzisa i-electrode ye-tungsten engasetyenziswayo kunye ne-foot pedal yokulawula i-amperage, ivumela abawelda ukuba balungise ubushushu ngendlela echanekileyo. Eli nqanaba lolawulo libalulekile kwi-brass: lithintela ubushushu obugqithisileyo, linciphisa ukufuma kwe-zinc, kwaye linciphisa umngcipheko we-porosity—iziphene eziqhelekileyo kwezinye iindlela zokuwelda ezifana ne-MIG okanye i-gas welding. Kwii-brass sheets ezincinci okanye iityhubhu ezincinci (eziqhelekileyo kwizicelo ze-elektroniki kunye ne-HVAC), amandla okufaka ubushushu obuphantsi e-TIG akwathintela ukugoba, ukugcina imo yokuqala kunye nokuthembeka kwezinto.
Enye inzuzo enkulu yokuwelda kwe-TIG xa kuhlanganiswa ubhedu kukugqitywa kwayo okucocekileyo, okungenazingxobo. Ngokungafaniyo nokuwelda okunamathelayo, i-TIG ayifuni ukujijeka, nto leyo ephelisa isidingo sokucoca emva kokuwelda ukuze kususwe iintsalela ze-slag—okonga ixesha elininzi kwiindawo zokusebenzela ezixakekileyo. Igesi yokukhusela engangenisi mandla (eqhele ukuba yi-argon okanye umxube we-argon-helium) esetyenziswa kwi-TIG welding ikwakhusela ichibi lokuwelda ekungcolisweni komoya, ithintela i-oxidation kwaye iqinisekisa umthungo ogudileyo, ofanayo oqinileyo kwaye okhangayo. Oku kutshintsha umdlalo kumsebenzi wokuhombisa ubhedu okanye izinto apho ukumelana nokugqwala kungaxoxiswana, njengeendawo zasemanzini okanye zepayipi.
Ukhuseleko lolunye ummandla apho i-TIG ikhanya khona kwi-Brass Welding. Nangona zonke iindlela zokuwelda zebrass zinomngcipheko wokuvezwa ngumsi we-zinc, ulawulo oluchanekileyo lobushushu lwe-TIG lunciphisa ubungakanani bokufuma kwe-zinc xa kuthelekiswa neendlela zobushushu obuphezulu ezifana ne-oxyacetylene welding. Xa idibene nomoya ofanelekileyo kunye nezixhobo zokuzikhusela (PPE), i-TIG idala indawo yokusebenza ekhuselekileyo—into ephambili kumashishini afuna ukuthobela imigaqo ye-OSHA kunye ne-HSE. Ukongeza, ukuwelda kwe-TIG akubangeli sparks okanye ukusasazeka, okunciphisa iingozi zomlilo kwiindawo zokusebenzela ezinezixhobo ezinokutsha.
Kubalulekile ukuqaphela ukuba i-TIG welding ayisosisombululo esifanelekileyo kuzo zonke izinto, kodwa ukusetyenziswa kwayo ngeendlela ezahlukeneyo kuyenza ihambelane neemfuno ezininzi zokudibanisa ubhedu ngokuchanekileyo. Isebenza nge-low-zinc (alpha) kunye ne-high-zinc (alpha-beta) brass alloys, kwaye inokusingatha ubukhulu ukusuka kwiigeyiji ezincinci (ngaphantsi kwe-1.5mm) ukuya kwi-9mm ngezinto ezifanelekileyo zokugcwalisa. Kwi-high-zinc brasses, ukusebenzisa intonga yokugcwalisa engenazinc kunye negesi yokukhusela ene-helium eninzi kunciphisa ngakumbi imveliso yomlilo kunye nokubola, kuqinisekisa ii-welds ezinamandla nezithembekileyo.
Kubathengi kunye nabenzi bezinto abavavanya iindlela zokuWelda ngeBrass, isigqibo ekugqibeleni sixhomekeke kwizinto eziza kuqala kuwe. Ukuba ufuna isantya ngaphezu kwayo yonke into, ukuWelda ngeMIG kusenokufanelekela iindawo zobhedu ezityebileyo. Kodwa ukuba ukuchaneka, ukuhambelana, kunye nomgangatho akunakuxoxiswana ngazo—ingakumbi kwizicelo ezibalulekileyo okanye ezintle—ukuWelda ngeTIG lukhetho olucacileyo. Ijongana nemingeni eyahlukileyo yobhedu njengezinto, ihlangabezana nemigangatho engqongqo yamashishini aphambili, kwaye inika iziphumo ezinciphisa ukuphinda kusetyenziswe kwaye iphucule ixabiso lemveliso yokugqibela.
Kwihlabathi lokudibanisa ibrass ngokuchanekileyo, ukunqumla iindlela ngeendlela ezisisiseko zokuwelda kudla ngokukhokelela kwiingxaki ezininzi ekuhambeni kwexesha. Ukuwelda kwe-TIG akuyonto inyukayo kwiindlela zemveli—kukutyala imali kumgangatho ohlawula ukusebenza ngcono, imisebenzi ekhuselekileyo, kunye nabathengi abonwabileyo. Nokuba ungumenzi wezinto onamava okanye usaqala ukusebenza ngebrass, ukutshintshela kwi-TIG kunokuba ngumahluko phakathi kweziphumo ezilungileyo nezibalaseleyo.
