Kumhlaba wanamhlanje wemizi-mveliso oqhutywa ziimfuno zokukhanya, amandla aphezulu, kunye nokusebenza kakuhle okuphezulu, i-Medium Frequency Direct Current Inverter.Spot Weldersibe ngumgangatho wegolide wokwenziwa okuphezulu{0}}kwisiphelo semoto, i-aerospace, kunye ne-elektroniki echanekileyo. Ngaphezulu nje kokuphucula kwiiwelder ze-AC zemveli, itekhnoloji ye-MFDC imele utshintsho olusisiseko ekujoyineni ngokuchanekileyo.
Esi sikhokelo sibonelela ngocazululo olubanzi lobuchwephesha be-MFDC, ukusebenza kwayo kuzo zonke izixhobo ezahlukeneyo, kunye neengqwalasela ezibalulekileyo zokuthengwa nokugcinwa.
Undoqo woBugcisa: Kutheni i-MFDC Igqwesa i-AC yesiNtu
Ukongama kwe-MFDC welding ilele kwinkqubo yayo yokuguqula amandla entsonkothileyo. Iguqula umbane oqhelekileyo we-50/60Hz AC ube phezulu-i-frequency (1000Hz+) AC nge-inverter, ethi emva koko ithotywe iphinde ilungiswe ibe yi-DC egudileyo, eqhubekayo.
Amandla e-1000Hz Inverter Technology
Iintsimbi ze-AC zemveli zisebenza kwi-50 / 60Hz, oku kuthetha ukuba i-current cross "i-zero point" amaxesha angama-100-120 ngesibini. Oku kukhokelela kwixesha elibalulekileyo lokufa apho kungabikho bushushu buveliswayo, okwenza inkqubo ibe sesichengeni sokuguquguquka kwamandla ombane kunye nokunciphisa ukuchaneka kolawulo.
Iinkqubo ze-MFDC, ezisebenza kwi-1000Hz okanye ngaphezulu, zinika ixesha lokuphendula langoku elingaphezu kwamaxesha angama-20 ngokukhawuleza kuneeyunithi ze-AC.

Le mpendulo ikhawulezayo ivumela i-welding yangoku ukuba ifikelele kwixabiso layo ekujoliswe kuyo phantse ngoko nangoko, icuthe kakhulu imijikelo ye-weld kunye nokunyusa umthamo opheleleyo.
Impembelelo ye-DC Output kwi-Weld Integrity
Imveliso ye-DC egudileyo ye-welder ye-MFDC ibonelela ngeenzuzo ezininzi ezibalulekileyo kumgangatho we-weld:
- Ukupheliswa kweZero{0}}Ukuwela:Ngokungafaniyo neziwelda ze-AC, apho ubushushu obufakwayo buphazanyiswa kuyo yonke iqanda-ukunqumla, i-DC ibonelela ngamandla obushushu obuqhubekayo. Oku kuqinisekisa ukukhula okuzinzileyo kwe-nugget kwaye kuphelisa i-weld spatter.
- Igalelo loBubushushu obuNxibeleleyo:Amandla eDC agqale ngakumbi, akhokelela kubushushu obuncinane-iNdawo eChaphazelekayo (HAZ). Oku kunciphisa ukugqwetheka komsebenzi kunye noxinzelelo olushiyekileyo, rhoqo kususa imfuno yesithuba-ukulungiswa kweweld okanye ukucola.
- UBomi obandisiweyo be-Electrode:Ngokubonelela ngomsinga ozinzileyo ngaphandle kokunyuka okuphezulu, ubuchwepheshe be-MFDC bunciphisa ukunxitywa kwe-electrode ngaphezulu kwe-50%. Oku kunciphisa ukuphindaphinda kokunxiba kwe-electrode kwaye kunciphisa ixesha lokuphumla kwimveliso.
Izicelo zeMathiriyeli eziPhezulu kunye nokuPhuculwa kweNkqubo
Abashiseli be-MFDC bayagqwesa apho izixhobo zemveli zisokola, ngakumbi ngemathiriyeli enomngeni kwiipropati zobushushu okanye zombane.
Intsimbi yeGalvanized: Ukulawula i-Zinc Vapor kunye nokuNgcola
I-Welding galvanized steel iyaziwa ngokuba nzima kakhulu ngenxa yokuba i-zinc coating (indawo yokunyibilika ~ 419 degree) iyancipha ixesha elide ngaphambi kokuba intsimbi (i-melting point ~ 1500 degree) iyancibilika. Lo mphunga unokungcolisa i-electrode kwaye uphazamise amandla e-weld.
- I-MFDC i-Advanteji: Ulawulo oluchanekileyo lwangoku kunye nethambeka lobushushu elikhawulezayo-phezulu kwe-MFDC livumela i-weld nugget yenze phambi kokuba kwenzeke umphunga omninzi we-zinc. Oku kukhusela i-electrode kwaye iqinisekisa{2}}amandla aphezulu, iiwelds ezicocekileyo ngobuhle.
I-Aluminiyam ialloys: UkuDityaniswa okuZinzileyo kuPhezulu{0}}Iintsimbi zokuSebenza
I-Aluminiyam ephezulu ye-thermal kunye ne-conductivity yombane, idityaniswe ne-oxyde layer yayo enenkani, yenza kube ngumngeni wokumelana nokuwelda.
- I-MFDC i-Advantage: Imveliso ye-DC egudileyo iqhekeza ngokufanelekileyo umaleko we-oxide kwaye ibonelela ngobushushu obuqinileyo obufunekayo ukuze kumiswe i-nugget ezinzileyo. Oku kwenza i-MFDC ibe ngumgangatho woshishino we-aluminiyam yomzimba-kwi-indibano emhlophe (BIW) kwimveliso yeemoto.
Advanced High{0}}Intsimbi yamandla : Ukuqinisekisa uKhuseleko kuLwakhiwo
Amabanga e-AHSS (njenge-DP okanye i-TRIP steels) afuna ulawulo oluchanekileyo lobushushu ukugcina amandla abo ngaphandle kokuphazamisa ubushushu{0}}INdawo echaphazelekayo.
- I-MFDC i-Advantage: abalawuli be-MFDC baxhasa i-multi-i-pulse welding kunye neprofayile yobushushu ephucukileyo. Ngokusebenzisa i-pulse yesibini ye-"tempering" emva kwe-weld engundoqo, inkqubo inokwandisa i-microstructure ye-nugget, ithintele i-HAZ embrittlement kunye nokuqinisekisa imfezeko yesakhiwo sokhuseleko{2}} amacandelo abalulekileyo.
IQhinga lokuThenga iiMpahla: Uchonga njani izixhobo ezisemgangathweni
Utyalo-mali kubuchwepheshe be-MFDC kukuzibophelela okubalulekileyo. Abathengi kufuneka bajonge ngaphaya kwethegi yexabiso ukuqinisekisa ukuba bafumana inkqubo yokusebenza ephezulu{1}.
