Ngaphakathi kwiNkqubo yokuVelisa iFlux Cored Wire: Iingxaki eziphambili kunye nokulungiswa okuqinisekisiweyo

Ukunyuka kweFlux Core Welding Wire

Kule minyaka yangoku,ucingo lokuwelda oluphambili lwe-fluxIvele njengokhetho olukhethwayo kumashishini afana nokwakha iinqanawa, izakhiwo zentsimbi, ukumbiwa kwemigodi, kunye nokuveliswa kwezixhobo ezinzima. Ukunyuka kwayo ngokukhawuleza kubangelwa yimfuno yezisombululo zokuwelda ezisebenzayo kakhulu, ezingabizi kakhulu, neziguquguqukayo.

Xa kuthelekiswa ne-solid wire okanye ii-electrode ze-stick zendabuko, i-flux cored wire inikezela ngamazinga aphezulu okufaka, umgangatho ophuculweyo we-weld, kunye nokusebenza okugqwesileyo kuzo zonke iindawo zokuwelda. Ezi nzuzo ziyenza ixabiseke ngakumbi ekwenziweni okukhulu apho isantya namandla zibaluleke kakhulu.

Iingenelo eziphambili zeFlux Core Welding Wire

Ukuthandwa okuqhubekayoucingo lokuwelda oluphambili lwe-fluxisekelwe kwiingenelo ezininzi zobugcisa: 

Ukusebenza kakuhle kwe-welding: Imveliso ifikelela kwi-3-5 ngokuphindwe kathathu kunee-electrodes zemveli.

Ubuchule bokubeka zonke iindawo: Ifanelekile kwiiwelds ezithe nkqo, ezithe tye, nezingaphezulu.

Ii-welds ezicocayo nezicocayo: Ingakumbi nge-wire core flux ecocayo ephantsi, nto leyo enciphisa ixesha lokucoca emva kokucocwa.

Iifomyula ezinokwenziwa ngokwezifiso: Ukukwazi ukulungisa izithako eziphambili kuvumela iingcingo ezikhethekileyo ukuhlangabezana neemfuno ezithile zesinyithi.

Ukusebenza kakuhle kweendleko: Ixabiso lilonke lokuwelda linciphile kakhulu ngenxa yokusebenza kakuhle okuphezulu kunye nokuchithwa kwezinto ezisetyenzisiweyo okuphantsi.

Imingeni ephambili ekuvelisweni kweentambo

Nangona kukho iingenelo, ukuveliswa kwe-flux cored wire kudala imingeni emininzi yobugcisa enokuchaphazela umgangatho wemveliso kunye nokuhambelana kwayo:

Ukusasazwa komgubo okungalinganiyo: Ukutshintshwa komgubo ngexesha lokuqengqeleka kunokubangela iindawo ezingenanto okanye ukuwelda okubuthathaka.

Ukuqina koomatshini okubuthathaka: Ukungazalisi ngokwaneleyo okanye imithungo engomelelanga kunokubangela ukudilika kwentambo, ukuvuza, okanye ukwaphuka.

Iziphene kunye nokuvuleka komphezulu: Zidla ngokunxulunyaniswa nongcoliseko okanye ukungangqinelani kokwakheka kwe-core.

Ukuqhekeka rhoqo ngexesha lokuzoba: Ngokwesiqhelo kubangelwa kukuxinana okungafanelekanga, ukuqina komsebenzi kakhulu, okanye ukungalungelelani kakuhle kweerola.

Amaqhinga okuphucula iinkqubo

Ukujongana nale miqobo yemveliso, abavelisi kufuneka bagxile ekudibaniseni ukuphuculwa kwezixhobo, ukuphathwa kwezinto, kunye nolawulo lweenkqubo.

Ukulinganiswa kwezixhobo kunye noqwalaselo lwerola

Ukulungelelaniswa ngokufanelekileyo kweerola zokwakha kubalulekile ukuqinisekisa ukuba umthungo uhlala uthe tye kwaye uvalwe kakuhle. Iirola ezingalungelelaniswanga kakuhle zinokukhokelela kwimithungo ye-helical okanye ukujija kakhulu, okubangela ukuvuza komgubo okanye ukuguqulwa kwentambo. Isithuba serola kunye nolandelelwano lokucinezelwa kufuneka zilinganiswe ukuze kuncitshiswe kancinci kancinci ukuze kugcinwe ukuthembeka kwentambo.

Umgangatho wePowder ePhambili kunye nokuphathwa kwayo

Iimpawu zokuhamba komgubo oyintloko zibalulekile. Ubungakanani bamasuntswana, imilo, kunye nobunyulu buchaphazela ukuhambelana kokuzaliswa kunye nokuziphatha kokudibanisa. Umgubo ocolekileyo kakhulu unokunciphisa ukuhamba kwamanzi, ngelixa amasuntswana arhabaxa anokukhokelela ekuhlukaneni. Kwintambo yomthombo ongundoqo osasazeka kancinci, ukugcina ukulingana kwe-alloy kubalulekile ukunciphisa i-oxidation kunye nokuphucula ukubonakala kwe-weld.

Ukucocwa kunye nokunyangwa ngaphambi konyango lwe-Steel Strip

Ngaphambi kokuba kwenziwe, umcu wentsimbi kufuneka ungabi naoyile kunye nongcoliseko. Igrisi eseleyo inokubanjwa ngaphakathi kwentambo, nto leyo ebangela ukuqhekeka kwegesi okanye nokubanda ngexesha lokuwelda. Ukucoca nge-ultrasound yindlela esebenza kakhulu, esebenzisa amandla okukhupha iiseli ukuze kukhutshwe amasuntswana kwaye kuqinisekiswe ukuba umphezulu ucocekile.

Ulawulo oluLungileyo lweNqanaba lokuzalisa

Izinga lokuzalisa—umlinganiselo womgubo ukuya kubunzima bentambo iyonke—kufuneka ulawulwe ngokuqinileyo. Izinga lokuzalisa eliphantsi libangela ukuba iingcingo ezingazaliswanga ngokwaneleyo zikwazi ukudilika, ngelixa izinga lokuzalisa eliphezulu linyusa umngcipheko wokuvuza kwaye lenze ubunzima ekuvaleni umthungo. Ukulinganisela izinga lokuzalisa kubalulekile ukuqinisekisa ukuhambelana kokuwelda kunye nokusebenza kakuhle koomatshini.

Umlinganiselo woxinzelelo lwentambo kunye nokuqina komsebenzi

Uxinzelelo oluphezulu ngexesha lokwenziwa lukhokelela ekuqineni komsebenzi, oko kwandisa amandla okutsalwa kodwa kunciphisa ukudumba. Oku kwenza ucingo lube sesichengeni sokuqhekeka kumanqanaba okugqibela. Ukusebenzisa ii-roller dies endaweni ye-fixed molds ekuqaleni kokudweba kunceda ekunciphiseni uxinzelelo lwangaphakathi kwaye kugcina ukudumba.

Amandla okuDweba kunye noLawulo lwesantya

Inkqubo yokutsala kufuneka ilinganise amandla okutsala kunye nesantya. Amandla okutsala agqithisileyo abangelwa kukucinezelwa okuphezulu okanye i-die geometry engafanelekanga anokubangela ukuqhekeka kwentambo ngequbuliso. Icebo lokukhawulezisa kancinci kancinci—eliqala ngesantya esiphantsi—linceda ekunciphiseni iincopho zoxinzelelo kwaye likhuthaze ukuguquguquka okufanayo.

Iingcebiso Ezisebenzayo kunye neeNgcebiso Zokuwelda

Ukuze usebenze kakuhle kakhulu, nazi ezinye iingcebiso ezisebenzayo zokuwelda nge-flux core wire welding:

Ngentsimbi engagqwaliyoucingo oluphambili lwe-flux, hlamba kakuhle iindawo ngaphambi kokuba zicocwe kakuhle uze usebenzise i-DCEN (Direct Current Electrode Negative) apho kufanelekileyo.

Sebenzisa ubungakanani obufanelekileyo bencam yokuthintana ukuze uphephe iingxaki zokutya, ingakumbi xa usebenzisa ucingo oluqinileyo olunemibhobho yokukhupha amanzi.

Gcina iingcingo kwindawo ezomileyo nezilawulwa bubushushu ukuze kuthintelwe ukungcoliswa komswakama.

Lungisa i-voltage kunye ne-wire feed rate kwiindawo ezahlukeneyo ukuze ugcine uzinzo lwe-arc kunye nokungena kwayo.
