Eyakhoumatshini wokuwelda indawoyindlu yamandla yokusebenza kakuhle, kodwa ukusebenza kwayo kulunge kuphela njengeendawo ozityisayo. Abaqhubi abaninzi bajonga inyathelo elibalulekileyo: ukucoca izixhobo zokusebenza. Ungcoliseko olufana neoyile, igrisi, kunye noomaleko be-oxide kumphezulu wesinyithi ziintshaba ezifihlakeleyo zeweld egqibeleleyo. Eli nqaku lichaza iimfuno eziyimfuneko zokucoca ukukhusela utyalo-mali lwakho kunye nokuqinisekisa iziphumo ezingenasiphako.
Kutheni ukuCoca kungaxoxiswana-
A umatshini wokuwelda indawoisebenza ngokudlula okwangoku ngentsimbi, isebenzisa ukuxhathisa kombane ukuvelisa ubushushu. Izinto ezingcolisa umphezulu zonyusa kakhulu oku kuxhathisa, okukhokelela ku:
Umgangatho weWeld ongalunganga:Ubushushu obungazinzanga bubangela i-spatter, iibhondi ezibuthathaka, kunye neziphene zangaphakathi ezifana ne-porosity.
UkuNxitywa kweZixhobo eziKhawulezayo:Ukungcola kwakha kwii-electrodes, kunyanzeliswa ukugcinwa rhoqo kunye nokutshintshwa.
Iingozi zokhuseleko:Ioyile inokumka ngoko nangoko, ibangele iintlantsi nemililo eyingozi.
Ukubeka nje, ukutsiba ukucoca kubiza kakhulu ekuhambeni kwexesha ngokulungiswa kunye nokusebenza kwakhona.
Iindlela ezimbini zokuCoca ezingundoqo zoMntu othembekileyoUmatshini we-Spot Welding
I-1, ukuCocwa kweMichiza: Ukuhambelana kunye neVolumu
Ilungele imveliso ephezulu{0}}, le ndlela isebenzisa ii-arhente zekhemikhali ukunyibilikisa ungcoliseko.
Ukuntywiliselwa:Ukucwina iinxalenye kwitanki yesisombululo sokucoca.
Ukosula:Ukusebenzisa isicoci ngelaphu okanye ngebrashi.
UKhetho lwesicoci:
Iintsimbi eziFrerous (Intsimbi, iStainless):Sebenzisa izicoci zealkaline ezomeleleyo ukuze uthobe kakuhle.
Ezingezizo-izinyithi zeFrorous (Aluminiyam, ubhedu):Khetha izisombululo ezingathathi hlangothi okanye ezithambileyo ze-alkaline ukunqanda ukufakwa komphezulu.
2,Ukucoca ngoomatshini: Ukuguquguquka nokuchaneka
Eyona nto ingcono kwiibhetshi ezincinci okanye iindawo ezintsonkothileyo, oku kususa ngokwasemzimbeni iioksidi kunye neefilimu.
I-Solvent Sula:Sebenzisa i-acetone okanye utywala bemizi-mveliso ukunyibilikisa ioyile.
Izixhobo eziAbrasive:Sebenzisa iibhrashi zentsimbi okanye i-sandpaper ukukhuhla i-oxidation de isiseko sesinyithi sikhazimle.
Inqaku elibalulekileyo:Amalungu acocwe ngolu hlobo kufuneka adityaniswe kwiiyure ezi-4 ukunqanda kwakhona{1}}i-oxidation.
Izinto -Isikhokelo sokuCoca esiKhethekileyo
Yenziwe ngentsimbi eshayinayo:Umaleko wayo oqinileyo weoksidi udla ngokufuna i-passivation okanye i-abrasive blasting emva kokucoca.
Aluminiyam:Yenza ifilimu ye-oxide enzima ngokukhawuleza. Sebenzisa izicoci ze-alkaline okanye iibhafu ze-ultrasonic kunye ne-weld ngokukhawuleza emva kokucoca.
Ubhedu:I-conductive ephezulu kodwa ithandwa kakhulu kwii-oxides ezibangela ukuxhathisa. Sebenzisa izicoci zobhedu ezizinikeleyo.
Intsimbi yeCarbon:Eshushu-intsimbi eqengqelekayo ifuna ukucocwa ngamandla (umzekelo, ukuchola), ngexa ebandayo{3}}iqengqeleka isenokufuna ukosulwa ngokulula.
Indlela yokuqinisekisa nokugcina ucoceko
UHlolo oluBonakalayo:Eyona ndlela ilula{0}}jonga iyunifomu, umphezulu wesinyithi ococekileyo.
Uvavanyo lwesixhobo:Kwizicelo ezibalulekileyo, sebenzisa izixhobo zokuhlalutya umphezulu wedatha yobuninzi.
Ukugcinwa kwe-Electrode:Rhoqo ukunxiba okanye ukubuyisela ii-electrodes ukunqanda{0}}ungcoliseko olusuka{1}}kwintsalela eyakhiweyo.
Ukuqukumbela
Ukwandisa imbuyekezo yakhoumatshini wokuwelda indawoiqala ngokulungiswa kwesixhobo sokusebenza esingenasici. Ngokudibanisa imichiza echanekileyo okanye inkqubo yokucoca ngoomatshini kwindlela yakho yokusebenza esemgangathweni, utyala imali ngokuthe ngqo kwintembeko ye-weld ephezulu, ukunciphisa ixesha lokuphumla, kunye nobomi bezixhobo obandisiweyo. Yenza ucoceko lwenzululwazi lube yinxalenye{2}}engaxoxiswanayo kumsebenzi wakho.
