Intshayelelo
Ubutyheli bomhlaba bumele umceli mngeni oqhelekileyo womgangatho ophakathi kwizicelo zokuwelda indawo, ngakumbi kumashishini apho inkangeleko yobuhle ibalulekile ecaleni kwengqibelelo edibeneyo. Oku kutshintsha kombala kubonisa i-oxidation yomphezulu obangelwa kukuvezwa okugqithisileyo kwe-thermal ngexesha lomjikelo we-welding. Ukuqonda izizathu ezingundoqo kunye nokuphumeza uhlengahlengiso olujoliswe kwiparameter kunokuphelisa ngokufanelekileyo lo mbandela ngelixa ugcina umgangatho we-weld ofanelekileyo.
- Inzululwazi ngasemva kweWeld Discoloration
Uphawu lwenkangeleko emthubi kumphezulu odityanisiweyo luvela kumaleko eoksidi abhityileyo athi enzeka xa amaqondo obushushu entsimbi esisiseko egqitha imida ebaluleke kakhulu kangangexesha elongeziweyo. Kwifrikhwensi ephakathiumatshini wokuwelda indawo izicelo, oku ngokuqhelekileyo kwenzeka xa amaxesha welding anda ngaphaya koluhlu olufanelekileyo, ukuvumela ioksijini ukusebenzisana kunye nemigangatho yesinyithi eshushu. Ubume bobushushu obugxininisiweyo bobuchwephesha bamaza aphakathi kufuneka bucuthe lo mngcipheko, kwenze ukuba tyheli sibe sisalathiso sokukhetha iparamitha esezantsi kunokunciphisa izixhobo.
- IziCwangciso zokuPhucula iParameter
Ukujongana nemiba etyheli kufuna indlela ecwangcisiweyo yohlengahlengiso lweparamitha kwindawo yakhoumatshini wokuwelda indawoMisela. Iimpawu eziphambili zolawulo ziquka:
- Ukunciphisa Ixesha le-Welding
Kuba ukuvezwa kwe-thermal ixesha elide kubonisa eyona nto ixhaphakileyo yokutshintsha kombala, ukunciphisa ngokuthe kratya ixesha le-weld ngelixa ukubeka esweni ingqibelelo edibeneyo kubonelela ngesona sisombululo sithe ngqo. Ukuphumeza ukuncitshiswa kwe-0.1-cycle increments, ukuqinisekisa ngovavanyo olutshabalalisayo ukuba i-nugget formation ihlala ifanelekile.
- Electrode Force Adjustment
Ukwandisa amandla e-electrode kuphucula ukudibana komphezulu kunye nokuqhutyelwa kwe-thermal kude ne-interface, ukunciphisa amaqondo okushisa aphezulu kunye ne-oxidation enokwenzeka. Uninzi lwamaza aphakathiumatshini wokuwelda indawoIinkqubo ziphendula kakuhle ekunyanzeliseni ukunyuka kwe-10-20% ngaphezu kwemimiselo eqhelekileyo yezicelo ezifanayo ngaphandle kwemiba ephuzi.
- Uphuculo lwangoku lweProfayile
Ngelixa igalelo lamandla lilonke lichaphazela ukutyheli, ukuhanjiswa kwangoku kuwo wonke umjikelo we-weld kudlala indima ebalulekileyo ngokulinganayo. Yangokuumatshini wokuwelda indawoabalawuli bavumela iprofayili yangoku ephucukileyo enokuthi igxininise amandla ngexesha lezigaba ezibalulekileyo zokwakheka kwe-nugget ngelixa kuncitshiswa ukufudumeza komhlaba.
- Uphuculo lweNkqubo yokuPholisa
Ulawulo olusebenzayo lwe-thermal ludlulela ngaphaya kohlengahlengiso lweparameter kwiinkqubo zokupholisa ngokomzimba. Ukuqinisekisa ukusebenza kakuhle kwakhoumatshini wokuwelda indawoIziseko zokupholisa ziquka:
- Ukuqinisekiswa kokuhamba kwamanzi
Qinisekisa ukuba amanqanaba okuhamba kwamanzi okupholisa ayahlangabezana nemigaqo yomenzi, ngokwesiqhelo iilitha ezi-4 ukuya kwezi-6 ngomzuzu kumaza aphakathi aphakathiumatshini wokuwelda indawoiinguqu. Ukuhamba okucuthiweyo kuhambelana ngokuthe ngqo kunye nokunyuka kwamaqondo obushushu e-electrode kunye nemingcipheko ephezulu yokutshintsha umbala.
IiProthokholi zoLondolozo
Ukuhlolwa rhoqo kweendlela zokupholisa kwiidiphozithi zamaminerali okanye izithintelo zigcina ukusebenza kakuhle kokutshintshisana kobushushu. Ukuphumeza ukuqinisekiswa kokuhamba kwenyanga kunye nenkonzo yokupholisa yonyaka kuthintela ukuthotywa komgangatho wokusebenza okudla ngokuba negalelo kwimiba etyheli ekuhambeni kwexesha.
- IiNgqwalasela zoLondolozo lwe-Electrode
Imeko ye-Electrode ichaphazela kakhulu iimpawu zokufudumeza komhlaba. Ubuso be-electrode obonakeleyo okanye obungcolisekileyo budala usasazo olungalinganiyo lwangoku olunokubangela ukufudumeza kwendawo kunye nokuguquka kombala okulandelayo. Ukuseka ishedyuli yokukhusela yokukhusela i-electrode dressing iqinisekisa ukudibanisa okuhambelanayo kunye nokusabalalisa ukushisa.
- UkuJonga iNkqubo kunye noQinisekiso loMgangatho
Ukuphumeza ulawulo lwenkqubo yobalo lomgangatho we-weld ibonelela kwangoko ekuphuhliseni iintsingiselo ezityheli phambi kokuba zibe zaliwe{0}}iziphene. Ukubeka iliso kwiiparamitha zombane kunye nokusebenza kwenkqubo yokupholisa kudala umfanekiso obanziumatshini wokuwelda indawoimpilo kunye nozinzo lwenkqubo.
Ukuqukumbela
Ukutyheli kwindawo ephakathi ye-welding imele umngeni wenkqubo enokusonjululwa kunomda wesixhobo esikhoyo. Ngokusebenzisa iparameter ekujoliswe kuyo, ukugcinwa kokusebenza kokupholisa, kunye nolawulo olungaguqukiyo lwe-electrode, abavelisi banokufezekisa zombini imfezeko yesakhiwo kunye nomgangatho wokuthambisa ofunwa ziimarike zanamhlanje. Amandla olawulo oluphezulu lwefrikhwensi yangoku ephakathiumatshini wokuwelda indawoIinkqubo zibonelela ngezixhobo eziyimfuneko zokuphelisa ukujika kombala ngelixa kugcinwe imigangatho yobulunga beweld.
