Imithombo kunye nezisombululo zeSpatter kwiMFDC Spot Welders
I-MFDC (i-Medium Frequency Direct Direct Current) abashiseli bamabalazisetyenziswa ngokubanzi kwi-metal processing ngenxa yokusebenza kwazo okuphezulu kunye nokuchaneka, ukubonelela ngenkxaso ebalulekileyo kwimveliso yamashishini. Nangona kunjalo, i-spatter ihlala ingumba ophambili ochaphazela umgangatho we-weld kunye nendawo yokusebenza kwimisebenzi ebonakalayo. Eli nqaku liphonononga imithombo ye-spatter kwiAbashiseli bamabala beMFDCkwaye iphakamisa izisombululo ezihambelanayo.
Imithombo yeSpatter
Imithombo ephambili ye-spatter kwiAbashiseli bamabala beMFDCingabalelwa kwezi zinto zilandelayo:
- Imilinganiselo yeWelding engafanelekanga:Izicwangciso ezingalunganga, ezifana nokugqithiswa kwangoku okanye ixesha elide le-welding, kubangela ukuba izinto ze-welding zigqithise. Oku kukhokelela ekugxothweni kwangoko kwesinyithi esinyibilikisiweyo, okukhokelela kwi-spatter.
- Usulelo loMphezulu:I-oyile, ukungcola, i-oxides, kunye nezinye izinto ezingcolileyo kwi-electrode okanye i-workpiece surface ivelisa iigesi xa ishushu ngexesha lenkqubo ye-welding. Ezi gesi zinokukhupha isinyithi esinyibilikisiweyo, zibangele i-spatter.
- I-Electrode engalunganga-ukuya{1}}uQhagamshelwano lomsebenzi:Uqhagamshelwano olungahambelaniyo lukhokelela kwi-arc yombane engazinzanga, ukwandisa umngcipheko we-spatter.
- Izixhobo zokuwelda ezikumgangatho ophantsi:{0}}Imathiriyeli yobulunga obuphantsi ihlala inemigangatho ephezulu yobumdaka, ethanda ukubangela isitshizi xa inyibilika.
- IMeko yesiXhobo esingesona siphezulu:Imiba yezixhobo ezifana nombane ongazinzanga, ii-electrode ezigugileyo, okanye ubushushu obugqithisileyo bamanzi okupholisa amanzi nawo anokuba negalelo kwisitshizi.
Izisombululo
Ukunciphisa okanye ukuphelisa i-spatter, la manyathelo alandelayo anokuthathwa, ukujongana nemithombo ekhankanywe ngasentla:
- Lungiselela iiParamitha zeWelding:Lungisa ixesha langoku, i-voltage, kunye nexesha le-welding ngokufanelekileyo ngokusekwe kwizinto ezithile zokuwelda kunye neempawu ze-workpiece ukuthintela ubushushu obugqithisileyo kunye nesitshizi esilandelayo.
- Coca imiphezulu ngokucokisekileyo:Phambi kwe-welding, qinisekisa ukuba zombini ii-electrode kunye neendawo zokusebenza zicocekile kwaye azinangcoliseko. Sebenzisa i-solvents ukucoca okanye i-abrasives (njenge-sandpaper) ukususa i-oyile, ukungcola kunye nee-oxides.
- Qinisekisa uQhagamshelwano olululo lwe-Electrode:Qinisekisa uqhagamshelwano oluhle phakathi kwe-electrode kunye ne-workpiece. Phinda{1}nxibe, lungelelanisa, okanye ubuyisele ii-electrodes njengoko kuyimfuneko.
- Sebenzisa{0}}Umgangatho ophezulu wezinto zeWelding:Khetha izinto ezithembekileyo,{0}eziphezulu eziqulathe ubumdaka obumbalwa ukunciphisa ukumila kwesitshizi.
- Yenza uLondolozo lweSixhobo rhoqo:Ukuqhuba uhlolo lweMFDC spot welder'samandlaukubonelela, i-electrodes, inkqubo yokupholisa, kunye nezinye izinto ezibalulekileyo. Shintsha ii-electrode ezigugileyo ngokukhawuleza, gcina ubushushu obufanelekileyo bamanzi okupholisa, kwaye uqinisekise ukuba isixhobo sisebenza ngokuzinzileyo.
- Sebenzisa iAnti{0}}iMilinganiselo yeSpatter:Sebenzisa iikhompawundi ezichasene{0}}nezitshizi okanye izixhobo zokhuseleko lwesitshizi ngexesha lokuwelda. La manyathelo anokunceda ukukhusela zombini umqhubi kunye nesixhobo kwimiphumo ye-spatter.
- Phucula iZakhono zoMsebenzisi:Ukuqeqesha abasebenzi be-welding ukuphucula ubuchule babo kunye nobuchule. Ukuqonda iindlela ezichanekileyo zokuwelda kunye nezenzo kunokunciphisa ngokufanelekileyo ukwenzeka kwe-spatter.
Ukuqukumbela
Ngamafutshane, ukusombulula imiba ye-spatter kwiAbashiseli bamabala beMFDC ifuna indlela-eneenkalo ezininzi. Oku kubandakanya ukwenza ngcono iiparamitha, ukucoca imiphezulu, ukuqinisekisa uqhagamshelwano olulungileyo, ukusebenzisa imathiriyeli esemgangathweni, ukugcina izixhobo zokusebenza, ukusebenzisa imilinganiselo yokuchasana -ne-spatter, kunye nokuphucula izakhono zokusebenza. Ngokusetyenziswa okubanzi kwala manyathelo, isitshizi sinokuncitshiswa kakhulu, okukhokelela kumgangatho ophuculweyo we-weld kunye nokusebenza kakuhle kwemveliso.
