Izinto Eziphambili Ezichaphazela Umgangatho Weld
Ukuwelda kokumelana kusebenzisa isiphumo sobushushu sombane. Xa umbane udlula kwiipleyiti ezimbini zesinyithi eziza kuwelda, ubushushu obuphezulu obuveliswa kukuxhathisa kwisekethe yokuwelda bunyibilikisa iipleyiti, ezithi emva koko zihlanganiswe phantsi koxinzelelo kwaye zipholiswe. Ukuxhathisa kokuwelda kuqulathe amacandelo amabini: ukuxhathisa kokunxibelelana phakathi kweepleyiti zesinyithi kunye nokuxhathisa komzimba weepleyiti ngokwazo. Ke ngoko, ukuze kufezekiswe ukuwelda okuhle, kuyimfuneko ukunciphisa ukuxhathisa kokunxibelelana ngelixa kwandiswa ukuxhathisa komzimba kwezinto.
Ukulawula umgangatho we-weld, ezi parameter zintlanu zilandelayo kufuneka zilungiswe: ukumelana ne-welding, uxinzelelo lwe-welding, ukugqithana, isantya se-welding, kunye nenye into eguquguqukayo—i-tinplate. Ezi zinto zimisela isithuba se-weld nugget, ubungakanani bokunyibilika, imo, kunye ne-microstructure yee-weld nuggets. Ezi parameters zinxulumene; xa i-parameter enye itshintsha, iimeko ze-welding kufuneka ziphinde zisetyenziswe.
(1) Ubudlelwane Phakathi kwesantya sokuWelda kunye nombane wokuWeldaXa ezinye iimeko zihlala zingaguquki, ukuze kufunyanwe i-weld elungileyo, isantya sokuwelda esimiselweyo kunye nomsinga wokuwelda kufuneka kuqinisekise ukuba i-tinplate iyanyibilika ngokufanelekileyo kwaye ii-weld nuggets zidibana. Xa isantya sokuwelda sisanda, umsinga kufuneka unyuswe ngokuthe ngcembe. Ukuba isantya sokuwelda siphantsi kakhulu, i-tinplate inokutshisa kakhulu, nto leyo ebangela ukuba ii-weld nuggets ziphole kancinci kune-tinplate eqhotyoshekayo, nto leyo ebangela ukuba kubekho imingxunya emikhulu kwiindawo zokuwelda. Ngokwahlukileyo koko, ukuba isantya sokuwelda siphezulu kakhulu, sinokukhokelela kwii-weld nuggets ezingadibaniyo. Ukongeza, ukufudumeza okunganelanga kwe-tinplate kunokudala imingxunya emide okanye i-tin soldering phakathi kweepleyiti.
(2) Ubudlelwane Phakathi koXinzelelo lokuWelda kunye noMsinga wokuWeldaUmaleko wetin kumphezulu wetinplate yintsimbi eqhuba kakuhle enokumelana okuphantsi, kwaye ubunzima bayo obuphantsi buyenza iguquguquke lula xa iphantsi koxinzelelo, nto leyo enciphisa kakhulu ukumelana nomphezulu kwaye iququzelele ukuwelda. Umsinga wokuwelda uyanda xa ixinzelelo lokuwelda kuba uxinzelelo oluphezulu lunyusa indawo yoqhagamshelwano lwetinplate, lunciphisa ukumelana nomphezulu wokuwelda, ngaloo ndlela lufuna ukwanda okulinganiselweyo kumsinga wokuwelda. Uxinzelelo lokuwelda kufuneka lulungiswe ngaphakathi koluhlu olufanelekileyo. Ukuba uxinzelelo luphantsi kakhulu, i-weld bead iya kuba phezulu, nto leyo eyenza kube nzima ukugalela. Ngokwahlukileyo koko, uxinzelelo oluphezulu lokuwelda lufikelela ngokulula umthungo we-weld othe tyaba.
(3) Ubudlelwane Phakathi Kokugqubana kunye Nomsinga WokuweldaUgqubana olukhulu lufuna ubushushu obuninzi bokuwelda, ngoko ke umsinga wokwelda uyanda kunye nogqubana. Phantsi kweemeko zokuwelda ezimiselweyo, ukuba ugqubana lukhulu kunesiqhelo, indawo ephantsi koxinzelelo olufanayo lokwelda iyanda, kunciphisa uxinano lomsinga wokwelda kwaye kwandisa kancinci ukumelana noqhagamshelwano, okubangela ubushushu bokwelda obungonelanga kunye nee-welds ezibandayo. Ngokwahlukileyo koko, ukunciphisa ugqubana kunokukhokelela ekugqubaneni kakhulu kunye nokwanda kokukhupha.
(4) Impembelelo yeempawu zeTinplate kwiWelding
1. Ubunzima bokugquma ngeTinUbunzima bokugquma ngetin kwi-tinplate buchaphazela umgangatho wokugquma. Nangona umaleko wetin unokumelana okuncinci kokunxibelelana kwaye ungumqhubi olungileyo, ukuba ubunzima bokugquma ngetin buphantsi kakhulu (ngaphantsi kwe-0.5 g/m²), kwaye umaleko we-alloy uphezulu, ukumelana nomphezulu womphezulu womaleko we-alloy mkhulu, nto leyo eyonakalisa umgangatho wokugquma. Ingakumbi kwibhetshi efanayo ye-tinplate, ukuba umaleko we-alloy uyahluka kakhulu okanye umxholo we-alloy tin uphezulu kakhulu, ukugquma okubandayo kunokwenzeka ngokulula phantsi kwezicwangciso ezifanayo. Kwi-tinplate enobunzima bokugquma ngetin ephezulu, isithuba se-weld nugget esifunyenwe ngomsinga ofanayo wokugquma sincinci kuneso sobunzima bokugquma ngetin ephantsi, ngoko ke ukugquma okuhle kufuna ukunciphisa isantya sokugquma. Ukongeza, ukuba umsinga wokugquma uphezulu kakhulu, i-tin inokungena kwimida yengqolowa yesinyithi ngexesha lokunyibilika, okunokubangela ukubola kwe-intergranular kwezinye iitini zokutya.
2. UbukhuluUbukhulu be-tinplate buchaphazela uhlengahlengiso lweeparamitha zokuwelda, ingakumbi kwiimashini zokuwelda ezikhawulezayo. Njengoko ubukhulu be-tinplate bukhula, umsinga wokuwelda ofunekayo uyanda, kwaye imida ephezulu nesezantsi yeemeko zokuwelda iyancipha ngokunyuka kobukhulu.
3. UkuqinaUkubekwa komsinga wokuwelda kunxulumene nobunzima bepleyiti yetin. Xa ubunzima busanda, umsinga wokuwelda kufuneka uncitshiswe ngokufanelekileyo. Phantsi kweemeko zokuwelda ezimiselweyo, umahluko kubukhulu bepleyiti yetin ngaphakathi kwemigangatho eqhelekileyo awuchaphazeli ukuwelda. Nangona kunjalo, ukuba ubukhulu kunye nobunzima buyahluka kakhulu ngaphakathi kwebhetshi enye, kuya kubangela umgangatho wokuwelda ongazinzile, okukhokelela kwimiba yokuwelda ebandayo okanye ukuwelda ngaphezulu. Umzekelo, phantsi koxinzelelo olumiselweyo, ukuba ubunzima bepleyiti yetin buyanda kakhulu, ukumelana nomphezulu phakathi kweepleyiti ezimbini kuyanda, okufuna ukuncipha komsinga wokuwelda.
4. Umgangatho weNsimbi eSesekweniXa intsimbi esisiseko inomxholo ophezulu wekhabhoni, umsinga wokuwelda kufuneka wonyuswe. Ukongeza, ukuba kukho izinto ezininzi ezifakiweyo kwintsimbi esisiseko, ukumelana kuyakhula ngexesha lokuwelda, nto leyo ebangela ukuchitheka lula. Ngamafutshane, xa kuveliswa iintlobo ezahlukeneyo zeetini ezingenanto okanye kutshintshwa uhlobo lwepleyiti yetin, kufuneka kuphinde kusetyenziswe iimeko ezintsha zokuwelda.
