Ukuqinisekisa ukuba i-passivation iyasebenza ngokufanelekileyo, iingcali zicoca nge-electrochemically ii-welds ezinde zeendawo ezigoqiweyo zentsimbi engagqwaliyo. Umfanekiso ngoncedo lweWalter Surface Technologies
Khawucinge ngomenzi ongene kwisivumelwano esibandakanya ukwenziwa kwentsimbi engagqwaliyo. Amacandelo esinyithi kunye neetyhubhu ayasikwa, agotywe aze adityaniswe ngaphambi kokuba afike kwindawo yokugqiba. Le nxalenye ineepleyiti ezidityaniswe ngokuthe nkqo kwityhubhu. Ii-weld zibukeka zilungile, kodwa ayilodayimethi egqibeleleyo umthengi ayifunayo. Ngenxa yoko, i-grinder ichitha ixesha isusa isinyithi esidityanisiweyo esingaphezulu kunesiqhelo. Emva koko, hayi, kwavela imibala eluhlaza okwesibhakabhaka engaphezulu - uphawu olucacileyo lokufakwa kobushushu obuninzi. Kule meko, kuthetha ukuba le nxalenye ayizukuhlangabezana neemfuno zabathengi.
Ukwenziwa ngesandla rhoqo, ukugaya nokugqiba kufuna ubuchule kunye nobuchule. Iimpazamo ekugqibeni zinokubiza kakhulu, xa kujongwa ixabiso elinikwe umsebenzi. Ukongeza izinto ezibizayo ezichaphazela ubushushu ezifana nentsimbi engagqwaliyo, iindleko zokulungisa kunye nokufakela izinto ezilahliweyo zinokuba phezulu. Xa zidibene neengxaki ezifana nongcoliseko kunye nokungaphumeleli kokusebenzisa i-passivation, umsebenzi wentsimbi engagqwaliyo owakha waba nenzuzo unokuba yintlekele elahlekayo okanye eyonakalisayo.
Abavelisi bakuthintela njani konke oku? Bangaqala ngokuphuhlisa ulwazi lwabo lokusila nokugqiba, baqonde indima abayidlalayo nganye nganye kunye nendlela ezichaphazela ngayo izinto zokusebenza zentsimbi engagqwaliyo.
Azizo amagama afanayo. Enyanisweni, wonke umntu uneenjongo ezahlukeneyo. Ukugaya kususa izinto ezifana nee-burrs kunye ne-weld metal excess, ngelixa ukugqiba kunika ukugqitywa kumphezulu wesinyithi. Ukudideka kuyaqondakala, xa ucinga ukuba abo baguba ngamavili amakhulu okugaya basusa isinyithi esininzi ngokukhawuleza, kwaye ukwenza njalo kunokushiya imikrwelo enzulu kakhulu. Kodwa ekugubeni, imikrwelo yinto nje emva koko; injongo kukususa izinto ngokukhawuleza, ingakumbi xa usebenza ngeesinyithi ezinoburhabaxa ezifana nentsimbi engagqwaliyo.
Ukugqiba kwenziwa ngamanyathelo, njengoko umqhubi eqala ngegrit enkulu aze aqhubekele phambili ukuya kumavili okugaya acolekileyo, ii-abrasives ezingelukiweyo, mhlawumbi nelaphu le-felt kunye ne-polish paste ukuze afezekise ukugqitywa kwesipili. Injongo kukufezekisa ukugqitywa okuthile kokugqibela (ipatheni yokukrwela). Inyathelo ngalinye (grit encinci) lisusa imikrwelo enzulu kwinyathelo langaphambili kwaye liyitshintshe ngemikrwelo emincinci.
Ngenxa yokuba ukugawula nokugqiba kuneenjongo ezahlukeneyo, zihlala zingahambelani kwaye zinokudlala ngokuchaseneyo ukuba kusetyenziswa icebo elingalunganga lokusetyenziswa. Ukususa isinyithi esigqithisileyo, abaqhubi basebenzisa amavili okugawula ukwenza imikrwelo enzulu kakhulu, baze banike loo ndawo kumntu ofaka impahla, oza kuchitha ixesha elininzi esusa le mikrwelo inzulu. Olu landelelwano lokugawula ukuya ekugqibeni lusenokuba yeyona ndlela isebenzayo yokuhlangabezana neemfuno zokugqiba zabathengi. Kodwa kwakhona, azizo iinkqubo ezihambelanayo.
Iindawo zokusebenza ezenzelwe ukwenziwa azidingi kugaywa nokugqityezelwa. Iindawo ezigayiweyo zenza oku kuphela kuba ukugaywa yeyona ndlela ikhawulezayo yokususa ii-welds okanye ezinye izinto kwaye imikrwelo enzulu eshiywe livili lokugaywa yiloo nto kanye umthengi ayifunayo. Iindawo ezifuna kuphela ukugqitywa zenziwe ngendlela engadingi kukhutshelwa kakhulu kwezinto. Umzekelo oqhelekileyo yinxalenye yentsimbi engatyiwayo ene-weld entle ekhuselweyo yegesi ye-tungsten efuna nje ukuxutywa kwaye ihambelane nephethini yokugqiba ye-substrate.
Iigrinder ezinamavili asuswayo kancinci zinokubangela iingxaki ezinkulu xa zisebenza ngentsimbi engagqwaliyo. Ngokufanayo, ukufudumala kakhulu kunokubangela ukuluhlaza okwesibhakabhaka nokutshintsha iimpawu zezinto. Injongo kukugcina intsimbi engagqwaliyo ipholile kangangoko kunokwenzeka kulo lonke ixesha lenkqubo.
Ngenxa yesi sizathu, kuyanceda ukukhetha ivili lokusila elinesantya sokususa esikhawulezayo ngokwesicelo kunye nohlahlo lwabiwo-mali. Amavili eZirconia asila ngokukhawuleza kune-alumina, kodwa kwiimeko ezininzi, amavili eseramikhi asebenza kakuhle.
Amasuntswana e-ceramic aqinileyo nabukhali kakhulu aguga ngendlela eyahlukileyo. Njengoko eqhekeka kancinci kancinci, awagayi ngokuthe ngcembe, kodwa agcina ubukhali obuphezulu. Oku kuthetha ukuba anokususa izinto ngokukhawuleza, rhoqo ngexesha elincinci kunezinye iivili zokugaya. Oku kwenza amasondo okugaya e-ceramic axabiseke kakhulu. Alungele ukusetyenziswa kwentsimbi engenasici kuba asusa iitships ezinkulu ngokukhawuleza kwaye avelise ubushushu obuncinci kunye nokugqwetheka.
Nokuba umenzi ukhetha liphi ivili lokusila, kufuneka kukhunjulwe ukuba ungcoliseko olunokubakho lufanele lukhunjulwe. Uninzi lwabavelisi bayazi ukuba abanakusebenzisa ivili lokusila elifanayo kwintsimbi yekhabhoni nakwintsimbi engatyiwayo. Abantu abaninzi bayahlula ngokwasemzimbeni imisebenzi yabo yokugaya ikhabhoni kunye nentsimbi engatyiwayo. Kwaneentyantyambo ezincinci zentsimbi yekhabhoni eziwela kwiindawo zokusebenza zentsimbi engatyiwayo zinokubangela iingxaki zongcoliseko. Amashishini amaninzi, afana namashishini amayeza kunye nenyukliya, afuna ukuba izinto ezisetyenziswayo zilinganiswe njengezingenangcoliseko. Oku kuthetha ukuba amavili okusila entsimbi engatyiwayo kufuneka angabi nanto (ngaphantsi kwe-0.1%) yesinyithi, isalfure kunye nekhlorine.
Amavili okusila awakwazi ukuzisila ngokwawo; adinga isixhobo samandla. Nabani na angancoma iingenelo zamavili okusila okanye izixhobo zamandla, kodwa inyani kukuba izixhobo zamandla kunye namavili azo okusila zisebenza njengenkqubo. Amavili okusila e-ceramic enzelwe ii-engile grinders ezinamandla athile kunye ne-torque. Nangona ezinye ii-air grinders zineenkcukacha ezifunekayo, uninzi lwe-ceramic wheel grinding lwenziwa ngezixhobo zamandla.
Iigrinder ezingenamandla aneleyo kunye ne-torque zinokubangela iingxaki ezinkulu, nokuba zinezinto ezirhabaxa eziphucukileyo. Ukungabikho kwamandla kunye ne-torque kunokubangela ukuba isixhobo sinciphise isantya xa siphantsi koxinzelelo, nto leyo ethintela amasuntswana e-ceramic kwivili lokusila ukuba enze oko ayenzelwe ukukwenza: ukususa ngokukhawuleza iziqwenga ezinkulu zesinyithi, ngaloo ndlela kunciphisa ubungakanani bezinto ezishushu ezingena kwivili lokusila.
Oku kuyawuqinisa umjikelo onzima: Abaqhubi bokugaya babona izinto zingasuswa, ngoko ke batyhala ngamandla ngokwemvelo, nto leyo edala ubushushu obugqithisileyo kunye nokuluhlaza okwesibhakabhaka. Bagqibela ngokutyhala ngamandla kangangokuba bagquma amavili ngeglasi, nto leyo ebenza basebenze nzima kwaye bavelise ubushushu obuninzi ngaphambi kokuba baqaphele ukuba kufuneka batshintshe amavili. Ukuba usebenza ngale ndlela kwiityhubhu ezincinci okanye amaphepha, bagqibela behamba ngqo kwizinto.
Kakade ke, ukuba abaqhubi abaqeqeshwanga kakuhle, nokuba besebenzisa izixhobo ezilungileyo, lo mjikelo unzima unokwenzeka, ingakumbi xa kufikwa kuxinzelelo abalubeka kwindawo yokusebenza. Eyona ndlela ilungileyo kukusondela kangangoko kunokwenzeka kumlinganiselo wangoku wegrinder. Ukuba umqhubi usebenzisa igrinder ye-10 amp, kufuneka acinezele ngamandla kangangokuba igrinder itsala malunga ne-10 amp.
Ukusebenzisa i-ammeter kunokunceda ukwenza imisebenzi yokusila ibe semgangathweni ukuba umenzi ucubungula intsimbi engagqwaliyo eninzi ebiza kakhulu. Kakade ke, zimbalwa izinto ezisebenzisa i-ammeter rhoqo, ngoko ke eyona ndlela ilungileyo kukumamela ngononophelo. Ukuba umqhubi uyeva aze azive i-RPM ihla ngokukhawuleza, usenokuba utyhala ngamandla kakhulu.
Ukumamela izinto ezichukunyiswayo zilula kakhulu (oko kukuthi, uxinzelelo oluncinci kakhulu) kunokuba nzima, ngoko ke kule meko, ukunikel’ ingqalelo ekuhambeni kwentlantsi kunokunceda. Ukugaya intsimbi engatyiwayo kuya kuvelisa iintlantsi ezimnyama kunentsimbi yekhabhoni, kodwa kufuneka zibonakale kwaye ziphume kwindawo yokusebenza ngendlela ehambelanayo. Ukuba umqhubi ngequbuliso ubona iintlantsi ezimbalwa, kusenokwenzeka ukuba akasebenzisi uxinzelelo olwaneleyo okanye akagqumi ivili.
Abaqhubi kufuneka bagcine i-engile yokusebenza ehambelanayo. Ukuba basondela kwi-workpiece kwi-engile ephantse ibe tyaba (phantse ilingane ne-workpiece), banokubangela ubushushu obukhulu; ukuba basondela kwi-engile ephezulu kakhulu (phantse ityeke), banomngcipheko wokugrumba umphetho wevili kwisinyithi. Ukuba basebenzisa ivili lohlobo lwe-27, kufuneka basondele kumsebenzi kwi-engile ye-20 ukuya kwi-30 degrees. Ukuba banamavili ohlobo lwe-29, i-engile yabo yokusebenza kufuneka ibe malunga ne-10 degrees.
Amavili okusila ohlobo lwama-28 (anciphileyo) adla ngokusetyenziselwa ukusila kwiindawo ezithe tyaba ukususa izinto kwiindlela zokusila ezibanzi. La mavili anciphileyo asebenza kakuhle nakwii-engile zokusila ezisezantsi (malunga nama-5 degrees), ngoko ke anceda ekunciphiseni ukudinwa komqhubi.
Oku kwazisa enye into ebalulekileyo: ukukhetha uhlobo olufanelekileyo lwevili lokusila. Ivili lohlobo lwe-27 linendawo yokudibanisa kumphezulu wesinyithi; ivili lohlobo lwe-28 linomgca wokudibanisa ngenxa yesimo salo esijiyileyo; ivili lohlobo lwe-29 linomphezulu wokudibanisa.
Okwangoku amavili ohlobo lwe-27 aqhelekileyo anokwenza umsebenzi ugqitywe kwiindawo ezininzi, kodwa imilo yawo yenza kube nzima ukuphatha iindawo ezineeprofayili ezinzulu kunye namagophe, njengeendibano ezidityanisiweyo zeetyhubhu zentsimbi engagqwaliyo. Imilo yeprofayili yevili lohlobo lwe-29 yenza kube lula kubasebenzi abafuna ukugawula indibaniselwano yeendawo ezigobileyo nezithe tyaba. Ivili lohlobo lwe-29 lenza oku ngokwandisa indawo yoqhagamshelwano lomphezulu, oko kuthetha ukuba umsebenzisi akufuneki achithe ixesha elininzi egawula kwindawo nganye - icebo elihle lokunciphisa ukwakheka kobushushu.
Enyanisweni, oku kusebenza nakweyiphi na ivili lokusila. Xa usika, umqhubi akufuneki ahlale kwindawo enye ixesha elide. Masithi umqhubi ususa isinyithi kwi-fillet yeenyawo ezininzi ubude. Angaqhuba ivili ngesantya esifutshane sokunyuka nokuhla, kodwa ukwenza njalo kunokuyitshisa kakhulu i-workpiece kuba ugcina ivili kwindawo encinci ixesha elide. Ukunciphisa ukungenisa ubushushu, umqhubi anganqumla yonke i-weld kwicala elinye kufutshane nozwane olunye, aze aphakamise isixhobo (esinika i-workpiece ixesha lokuba iphole) aze anqumle i-workpiece kwicala elifanayo kufutshane nozwane olunye. Ezinye iindlela ziyasebenza, kodwa zonke zinophawu olunye olufanayo: ziyakuphepha ukutshisa ngokugcina ivili lokusila lihamba.
Iindlela ezisetyenziswa rhoqo "zokufaka amakhadi" nazo ziyanceda ekufezekiseni oku. Masithi umqhubi ucola i-butt weld kwindawo ethe tyaba. Ukuze anciphise uxinzelelo lobushushu kunye nokumba kakhulu, wayekuphepha ukutyhala i-grinder ecaleni kwejoyinti. Endaweni yoko, uqala ekupheleni aze atsale i-grinder ecaleni kwejoyinti. Oku kuthintela nevili ekumbeni kakhulu kwizinto.
Kakade ke, naluphi na uhlobo lobugcisa lunokutshisa kakhulu isinyithi ukuba umqhubi uhamba kancinci kakhulu. Hamba kancinci kakhulu kwaye umqhubi uya kushushu kakhulu isiqwenga somsebenzi; hamba ngokukhawuleza kakhulu kwaye ukugaya kungathatha ixesha elide. Ukufumana indawo emnandi yesantya sokutya kudla ngokufuna amava. Kodwa ukuba umqhubi akaqhelananga nomsebenzi, angagaya inkunkuma ukuze afumane "uvakalelo" lwesantya sokutya esifanelekileyo sesiqwenga somsebenzi esisesandleni.
Icebo lokugqiba lijikeleza imeko yomphezulu wento njengoko ifika kwaye iphuma kwicandelo lokugqiba. Chonga indawo yokuqala (imeko yomphezulu efunyenweyo) kunye nendawo yokuphela (ukugqitywa kuyafuneka), uze wenze isicwangciso sokufumana eyona ndlela ilungileyo phakathi kwezo ndawo zimbini.
Amaxesha amaninzi indlela engcono ayiqali ngesikrweqe esinamandla kakhulu. Oku kunokuvakala kuchasene nengqondo. Kaloku, kutheni ungaqali ngesanti erhabaxa ukuze ufumane umphezulu orhabaxa uze udlulele kwisanti ecolekileyo? Ngaba bekungayi kuba luncedo ukuqala ngesanti ecolekileyo?
Akunyanzelekanga ukuba oku kuphinde kudibane nendlela ezihlanganiswa ngayo izinto. Njengoko inyathelo ngalinye lifikelela kwi-grit encinci, i-conditioner ithatha indawo ye-scratches enzulu nge-scratches ezinzulu nezincinci. Ukuba ziqala nge-sandpaper ye-40-grit okanye i-flip disk, ziya kushiya imikrwelo enzulu kwisinyithi. Kungangcono ukuba loo mikrwelo isondeza umphezulu kufutshane nokugqitywa okufunekayo; yiyo loo nto ezo zinto zokugqiba i-grit ezingama-40 zikhona. Nangona kunjalo, ukuba umthengi ucela i-finish yeNombolo 4 (i-directional brushed finish), imikrwelo enzulu eyenziwe yi-Nombolo 40 abrasive iya kuthatha ixesha elide ukuyisusa. Ii-Dresser zidlula kwiisayizi ezahlukeneyo ze-grit, okanye zichithe ixesha elide zisebenzisa i-abrasives ezicolekileyo ukususa loo mikrwelo mikhulu kwaye ziyitshintshe nge-scratches encinci. Oku akupheleli nje ekubeni kusebenze kakuhle, kodwa kukwangenisa ubushushu obuninzi kwindawo yokusebenza.
Kakade ke, ukusebenzisa izinto ezirhabaxa ezicolekileyo kwiindawo ezirhabaxa kunokucotha kwaye, xa zidityaniswe neendlela ezingezizo, kunokubangela ubushushu obuninzi. Kulapho idiski ye-two-in-one okanye i-staggered flap disc inokunceda khona. Ezi diski ziquka amalaphu arhabaxa adityaniswe nezinto zokunyanga umphezulu. Zivumela ngokufanelekileyo i-dresser ukuba isebenzise izinto ezirhabaxa ukususa izinto ngelixa ishiya ukugqitywa okuthambileyo.
Inyathelo elilandelayo ekugqibeni kokugqibela linokubandakanya ukusetyenziswa kwee-nonwovens, nto leyo ebonisa olunye uphawu olukhethekileyo lokugqiba: inkqubo isebenza kakuhle ngezixhobo zamandla ezinesantya esiguquguqukayo. I-grinder ye-engile yasekunene esebenza kwi-10,000 RPM inokusebenza nezinye izixhobo zokusila, kodwa iya kunyibilikisa ezinye ii-nonwovens kakuhle. Ngenxa yesi sizathu, abagqibezeli banciphisa isantya sibe phakathi kwe-3,000 kunye ne-6,000 RPM ngaphambi kokuba baqale inyathelo lokugqiba ngee-nonwovens. Kakade ke, isantya esichanekileyo sixhomekeke kusetyenziso kunye nezinto ezisetyenziswayo. Umzekelo, ii-drums ezingelukiweyo zihlala zijikeleza phakathi kwe-3,000 kunye ne-4,000 RPM, ngelixa iidiski zonyango lomphezulu zihlala zijikeleza phakathi kwe-4,000 kunye ne-6,000 RPM.
Ukuba nezixhobo ezifanelekileyo (ii-variable speed grinders, i-finishing media ezahlukeneyo) kunye nokumisela inani elifanelekileyo lamanyathelo kubonelela ngemephu etyhila eyona ndlela ilungileyo phakathi kwezinto ezifikayo nezigqityiweyo. Indlela echanekileyo iyahluka ngokwendlela esetyenziswa ngayo, kodwa ii-trimmers ezinamava zilandela le ndlela zisebenzisa iindlela ezifanayo zokucheba.
Iirola ezingalukwanga zigqibezela umphezulu wentsimbi engatyiwayo. Ukuze ugqibezele kakuhle kwaye uphile ubomi obufanelekileyo, izixhobo ezahlukeneyo zokugqiba zisebenza kwii-RPM ezahlukeneyo.
Okokuqala, bathabatha ixesha labo. Ukuba babona into yokusebenzela ebhityileyo yentsimbi engagqwaliyo ishushu, bayayeka ukugqiba kwenye indawo baze baqale kwenye. Okanye basenokuba basebenza kwizinto ezimbini ezahlukeneyo ngaxeshanye. Basebenza kancinci kwenye baze basebenze kwenye, nto leyo enika enye into ixesha lokuba iphole.
Xa upolisha ukuya kugqiba isipili, ipolisha ingapolisha ngedrama yokupolisha okanye idiski yokupolisha, kwicala elithe nkqo kwinyathelo elidlulileyo. Upolisha ngesanti enqamlezileyo ubonisa iindawo ezifuna ukudibana nepatheni yokukrwela yangaphambili, kodwa aziyi kufikelela kumphezulu kwisipili esinguNombolo 8. Nje ukuba yonke imikrwelo isusiwe, kufuneka ilaphu elithambileyo kunye nevili lokuthambisa ukuze kugqitywe ukukhazimla okufunekayo.
Ukuze kugqitywe ngendlela efanelekileyo, abavelisi kufuneka banike abagqibi izixhobo ezifanelekileyo, kuquka izixhobo zokwenyani kunye neendaba, kunye nezixhobo zonxibelelwano, ezinje ngokuseka iisampulu ezisemgangathweni zokumisela ukuba kufuneka kujongeke njani ukugqitywa okuthile. Ezi sampuli (eziposwe kufutshane nesebe lokugqiba, kumaxwebhu oqeqesho, nakwiincwadi zokuthengisa) zinceda ekufumaneni wonke umntu kwikhasi elifanayo.
Ngokuphathelele izixhobo zokwenyani (kuquka izixhobo zamandla kunye nezixhobo ezirhabaxa), ijiyometri yeendawo ezithile inokubangela imingeni nakubasebenzi abanamava kakhulu kwicandelo lokugqiba. Kulapho izixhobo zobungcali zinokunceda khona.
Masithi umqhubi kufuneka agqibezele indibano yetyhubhu yentsimbi engagqwaliyo enodonga oluncinci. Ukusebenzisa iidiski zeflap okanye iidrama kunokubangela iingxaki, kubangele ubushushu obugqithisileyo, kwaye ngamanye amaxesha kwenze nendawo ethe tyaba kwityhubhu ngokwayo. Apha, ii-sander zebhanti ezenzelwe iityhubhu zinokunceda. Ibhanti yokuhambisa ijikeleza uninzi lobubanzi bombhobho, isasaze iindawo zokunxibelelana, inyuse ukusebenza kakuhle kwaye inciphise ukungena kobushushu. Oko kuthethiweyo, njengakwezinye izinto, i-dresser isadinga ukuhambisa i-sander yebhanti kwindawo eyahlukileyo ukunciphisa ukwakheka kobushushu obugqithisileyo kwaye iphephe ukuluhlaza okwesibhakabhaka.
Oku kuyasebenza nakwezinye izixhobo zokugqiba zobungcali. Cinga nge-finger belt sander eyenzelwe iindawo ezixineneyo. I-finisher ingayisebenzisa ukulandela i-fillet weld phakathi kwamabhodi amabini nge-engile ebukhali. Endaweni yokuhambisa i-finger belt sander ngokuthe nkqo (njengokuxukuxa amazinyo akho), i-dresser iyishukumisa ngokuthe tye ecaleni konyawo oluphezulu lwe-fillet weld, ize ilandele unyawo olusezantsi, ngelixa iqinisekisa ukuba i-finger sander ayihlali ixesha elide.
Ukuwelda, ukugaya kunye nokugqiba intsimbi engagqwaliyo kungenisa enye ingxaki: ukuqinisekisa ukungasebenzi kakuhle. Emva kwazo zonke ezi zinto ziphazamisayo kumphezulu wezinto, ngaba kukho naziphi na izinto ezingcolisayo ezinokuthi zithintele umaleko we-chromium yentsimbi engagqwaliyo ukuba ungakheki ngokwemvelo phezu komphezulu wonke? Into yokugqibela umenzi ayifunayo ngumthengi onomsindo okhalaza malunga neendawo ezigqwalisiweyo okanye ezingcolisiweyo. Kulapho ukucoca kunye nokulandeleka ngokufanelekileyo kubandakanyeka khona.
Ukucoca nge-electrochemical kunokunceda ukususa izinto ezingcolisayo ukuqinisekisa ukuba zingcoliswa ngokufanelekileyo, kodwa kufuneka kwenziwe nini oku kucoca? Kuxhomekeke ekusetyenzisweni. Ukuba abavelisi bacoca intsimbi engagqwaliyo ukuze bakhuthaze ukungcoliswa ngokupheleleyo, badla ngokwenza oko kwangoko emva kokuwelda. Ukungaphumeleli ukwenza oko kuthetha ukuba isixhobo sokugqiba sinokuthatha izinto ezingcolisayo ezingaphezulu kwindawo yokusebenza size sizisasaze kwenye indawo. Nangona kunjalo, kwezinye izicelo ezibalulekileyo, abavelisi banokukhetha ukufaka amanyathelo okucoca ongezelelweyo—mhlawumbi bade bavavanye ukungcoliswa ngokufanelekileyo ngaphambi kokuba i-stainless iphume kumgangatho wefektri.
Masithi umenzi udibanisa intsimbi engagqwaliyo ebalulekileyo kwishishini lenyukliya. Umenzi we-arc welder ochwephesha wegesi ubeka umthungo wedayime obonakala ugqibelele. Kodwa kwakhona, le yindlela ebalulekileyo. Umsebenzi kwicandelo lokugqiba usebenzisa ibrashi eqhagamshelwe kwinkqubo yokucoca nge-electrochemical ukucoca umphezulu we-weld. Emva koko wafaka uzwane lwe-weld ngeentsiba esebenzisa ilaphu elirhabaxa nelingenalukiweyo waza wagqiba yonke into ngendlela elinganayo. Emva koko kuza ibrashi yokugqibela enenkqubo yokucoca nge-electrochemical. Emva kokuhlala usuku okanye ezimbini, sebenzisa isixhobo sokuvavanya esiphathwayo ukuvavanya inxalenye ukuba ayiphazamisi ngokufanelekileyo. Iziphumo, ezirekhodwe kwaye zigcinwe nomsebenzi, zibonise ukuba inxalenye yayiphazamisiwe ngokupheleleyo ngaphambi kokuba iphume kumzi-mveliso.
Kwiindawo ezininzi zokwenza izinto, ukugaya, ukugqiba kunye nokucoca i-stainless steel passivation kwenzeka ngokulandelelana. Enyanisweni, zihlala zenziwa ngaphambi kokuba umsebenzi uthunyelwe.
Iindawo ezingagqitywanga kakuhle zivelisa ezinye zezona zinto zibiza kakhulu kwaye ziphinde zilungiswe, ngoko ke kuyavakala ukuba abavelisi bajonge kwakhona amasebe abo okugaya nokugqiba. Ukuphuculwa kokugawula nokugqiba kunceda ekunciphiseni iingxaki ezinkulu, ukuphucula umgangatho, ukuphelisa iintloko ezibuhlungu, kwaye okona kubaluleke kakhulu, ukwandisa ulwaneliseko lwabathengi.
