Intshayelelo
Kwishishini lokulungisa isinyithi, eliphakathioomatshini bokuwelda indawo rhoqozixhobo ezikhethiweyo kubakhiqizi abaninzi ngenxa yokusebenza kwabo okuphezulu kunye nokusebenza okuzinzileyo kwe-welding. Nangona kunjalo, kwimisebenzi ebonakalayo, ukwenzeka kweecraters emva kokuwelda akuchaphazeli inkangeleko yemveliso kuphela kodwa kunokubangela ingozi kumandla okwakhiwa kunye nobomi benkonzo yemveliso. Eli nqaku ligxile kumxholo othi "Indlela Yokusombulula Ingxaki YeCretha Emva KokuPhakathiI-Frequency Spot Welding?" ngokuphonononga nzulu oonobangela bemingxuma kunye nokubonelela ngezisombululo ezininzi ezinokubakho.
Iimbangela zeCraters
- IiParameters ze-Welding ezingafanelekanga: Ukusetwa okungafanelekanga kweeparameters ezifana ne-welding current kunye nexesha le-welding likhokelela ekugxininiseni ngokugqithiseleyo ukushisa kwe-welding, okubangela ukuncipha kokungalingani kwesinyithi esinyibilikisiweyo ngexesha lokuqina kunye nokwenza i-craters.
- Iimpawu zeMathiriyeli: Umahluko kwiipropathi ezibonakalayo ezifana ne-thermal conductivity kunye nendawo yokunyibilika kwezinto zetsimbi ezahlukeneyo zenza ukuba ezinye izinto zithandeke ngakumbi kwi-craters ngexesha le-welding.
- Imeko ye-Workpiece Surface Condition: Ubukho bamabala e-oyile, ii-oxides, okanye obunye ukungcola kumphezulu we-workpiece, okanye umphezulu ongalinganiyo, buchaphazela umgangatho we-welding kwaye kwandisa umngcipheko wokwakheka kwe-crater.
- I-Electrode Wear kunye neMilo: Ukugqoka i-electrode enzima okanye imilo engafanelekanga ikhokelela ekusasazeni okungalinganiyo kwangoku ngexesha le-welding, okubangela ukugqithiswa kwendawo kunye nokwakhiwa kwe-crater.
Izisombululo
- Lungiselela i-Welding Parameters: Lungiselela ngokuchanekileyo iiparitha ezifana ne-welding yangoku kunye nexesha le-welding ngokusekelwe kuhlobo kunye nobukhulu bezinto zokuthunga kunye nomgangatho ofunekayo we-welding. Ngeemvavanyo eziphindaphindiweyo, fumana indibaniselwano eyiyo yeeparamitha ukunqanda ubushushu obugqithisileyo.
- Phucula iMeko yoMphezulu woMsebenzi: Coca ngokucokisekileyo umphezulu womsebenzi phambi kwewelding ukususa amabala e-oyile, iioksidi, kunye nobunye ukungcola, uqinisekise umgangatho ogudileyo kunye nokhululekileyo. Iindlela ezifana nokusila okanye ukuqhunyiswa kwesanti zingasetyenziselwa ukuphucula umgangatho womphezulu.
- Khetha ii-Electrodes ezifanelekileyo: Khetha izixhobo ezifanelekileyo ze-electrode kunye neemilo ezisekelwe kwiimfuno ze-welding. Jonga rhoqo ukunxiba kwe-electrode kwaye utshintshe ii-electrode ezigugile kakhulu ngexesha elifanelekileyo ukuze uqinisekise ukuhanjiswa okuzinzile kwangoku.
- Faka phambi{0}}Amanyathelo oxinzelelo kunye nokuPholisa: Phambi{1}}cinezela i-workpiece phambi kwe-welding ukunciphisa i-deformation ngexesha lenkqubo ye-welding. Kwangaxeshanye, thatha amanyathelo okupholisa afanelekileyo, afana nokunyusa ukugeleza kwamanzi okupholisa okanye ukusebenzisa izixhobo zokupholisa, ukuthoba iqondo lobushushu kwindawo yokuwelda kunye nokunciphisa amathuba okubunjwa kwecrater.
- Iposti-Ukwenziwa kunye noLungiso: Kwicraters esele zikho, iposi{1}}iindlela zokulungisa ezinje ngokusila okanye ukuzalisa zingasetyenziswa. Khetha indlela efanelekileyo yokulungisa ngokusekwe kubukhulu nobunzulu be crater ukuqinisekisa ukuba umphezulu olungisiweyo udibana nomgangatho othe tyaba kunye nomgangatho wokuwelda.
- Uqeqesho kunye neNkxaso yobuGcisa: Ukuqinisa uqeqesho lwabaqhubi ukuphucula ukuqonda kwabo kunye nobuchule babo ekulungiseni iiparamitha ze-welding, unyango lwe-workpiece surface, ukhetho lwe-electrode, kunye nokutshintshwa. Ukongeza, bonelela ngenkxaso yobugcisa efunekayo ukujongana nemiba eyahlukeneyo edibene nayo ngexesha lenkqubo ye-welding.
Ngamafutshane, ukusombulula ingxaki yecraters emva kokuphakathii-frequency spot weldingifuna iindlela -ezineenkalo ezininzi, eziquka ukulungelelanisa iiparamitha zokuwelda, ukuphucula iimeko zomphezulu weworkpiece, ukukhetha i-electrode ezifanelekileyo, ukusebenzisa{1}}imilinganiselo yangaphambili yoxinzelelo kunye nokupholisa, ukwenza isithuba{2}}ukulungisa nokulungiswa, kunye nokwandiswa koqeqesho nenkxaso yobugcisa. Ngokuphumeza la manyathelo, umngcipheko wokwenziwa kwe-crater unokucuthwa ngokufanelekileyo, uphucule umgangatho we-welding kunye nokukhuphisana kwemveliso.
