I-welding cast cast iron exhaust manifolds inokuvakala ngathi idibanisa iphazili entsonkothileyo. I-brittleness ye-iron cast, ngenxa yekhabhoni ephezulu, yenza ukuba ikwazi ukukrazula, ngakumbi phantsi kweenguqu ezikhawulezayo zeqondo lokushisa. Lo mngeni ubaluleke ngakumbi xa usebenza kumacandelo afana nekhupha izinto ezininzi kwi-injini yemoto, apho ukuqina kubalulekile ekusebenzeni kakuhle. Ukulungiswa okufanelekileyo, okufana nokucocwa ngokucokisekileyo kunye nokufudumala kwangaphambili, kunye nobuchule obuchanekileyo, kubalulekile ukulawula uxinzelelo lwe-thermal kunye nokufezekisa ukulungiswa okunamandla, okuqhubekayo. Nokuba ulungisa imiba ngeukusebenza harmonic balancer, imibhobho emininzi yaselwandle, okanye naliphi na elinye icandelo elibalulekileyo, umonde kunye nengqalelo kwiinkcukacha zingundoqo kwimpumelelo.
UNingbo Werkwell, inkokeli ethembekileyo kubunjineli boomatshini ukusukela ngo-2015, uhambisa iinxalenye zemoto ezikumgangatho ophezulu. Iqela labo le-QC elinezakhono liqinisekisa ukugqwesa kwiimveliso ezisusela kwi-trim yangaphakathi ukuya kwi-cast cast kunye ne-chrome plating, ukuhlangabezana neemfuno zokusebenza kweemoto zanamhlanje.
Imingeni yeWelding Cast Iron Exhaust Manifolds
Ubuqhophololo kunye nokuSensitivity kweThermal
Ii-manifolds zokukhupha i-iron ziyaziwa ngokuba brittle ngenxa yekhabhoni ephezulu. Le brittleness ibenza bathande ukuqhekeka, ngakumbi xa bevezwe kutshintsho olukhawulezayo lobushushu. I-welding cast cast iron exhaust manifolds ifuna ukuphathwa ngononophelo ukuthintela umonakalo ongakumbi. Ukufudumeza i-manifold ukuya kwi-400-500 degrees Fahrenheit kunokuncedisa ukunciphisa ukothuka kwe-thermal. Eli nyathelo linciphisa umngcipheko wokwenza iintanda ngexesha lenkqubo ye-welding. Ukusebenzisa izinto zokuzalisa ezisekelwe kwi-nickel kuqinisekisa ukuhambelana nentsimbi, ukudala i-weld enamandla kunye ne-crack-resistant-resistant.
UNingbo Werkwell, umenzi okhethekileyo kubunjineli boomatshini, uyakuqonda ukubaluleka kokuqina kwiindawo zemoto. Iqela labo le-QC elinamava liqinisekisa iimveliso ezikumgangatho ophezulu, ukusuka kwi-die casting ukuya kwi-chrome plating, ibenza igama elithembekileyo kwishishini.
Umngcipheko wokuqhekeka kwi-Heating engalinganiyo
Ukufudumeza okungalinganiyo ngomnye umceli mngeni xa usebenza ngeentsimbi zokukhupha izinto ezininzi. Ukuba enye inxalenye ye-manifold itshisa ngokukhawuleza kunenye, kunokukhokelela kuxinzelelo kunye nokuqhekeka. Ukuthintela oku, iiwelders zihlala zifudumeza yonke i-manifold ngokulinganayo. Ukusonga i-manifold kwizinto zokukhusela emva kwe-welding kuvumela ukupholisa okucothayo, okunciphisa ngakumbi umngcipheko wokuqhekeka. Le ndlela iqinisekisa ukuba i-manifold ihlala ilungile kwaye yomelele phantsi kobushushu obuphezulu.
Ukufezekisa iiWelds ezinamandla kunye nezizinzileyo
Ukudala i-weld eyomeleleyo kwaye ehlala ixesha elide kwi-cast iron exhaust manifold ifuna ukuchaneka kunye nezixhobo ezifanelekileyo. Abashicileli bahlala besebenzisa i-electrode ebukhali, ecocekileyo ye-tungsten kunye negesi ecocekileyo ye-argon ukuphepha ukungcola. Ukuqinisekisa ukuba i-weld puddle ingena kwi-multifold ngokufanelekileyo kubalulekile. Kwintsimbi yentsimbi engwevu, ukufudumeza kancinci kwangaphambili kunye ne-nickel electrode zisebenza kakuhle. I-nodular cast iron, ngakolunye uhlangothi, ixhamla kwi-preheating ephakathi. Ukuqwalasela iimeko zokusingqongileyo, ezifana nokuchanabeka kwiigesi ezishushu, nako kudlala indima ekufezekiseni ukulungiswa okuhlala ixesha elide.
I-Ningbo Werkwell iye yabonelela ngeengxenye zeemoto ukususela ngo-2015, igxile kumgangatho kunye nokuthembeka. Ubuchwephesha babo kwiinxalenye ze-trim yangaphakathi kunye neziqhoboshi ziqinisekisa ukuba yonke imveliso ihlangabezana neemfuno zentsebenzo yale mihla yeemoto.
Ukulungiselela i-Exhaust Manifold for Welding
Ukucoca umphezulu ngokucokisekileyo
Umphezulu ococekileyo sisiseko se-aweld ngempumelelo. Ukungcola, ioli, kunye neentsalela zetsimbi ezindala zinokuwenza buthathaka ibhondi, ngoko ke ukuyisusa kubalulekile. Iiwelder zihlala zilandela la manyathelo ukulungisa umphezulu:
- Bevel the Crack: Besebenzisa isixhobo sokusila, benza umsele omile okwe-V ecaleni kwentanda. Le groove iqinisekisa iibhondi zezinto zokuzalisa ngokufanelekileyo.
- Coca intsimbi yokuphosa: Zisusa zonke izinto ezingcolisayo, kuquka igrisi nomhlwa, de umphezulu ubonakale umenyezelayo kwaye umtyibilizi.
