Intshayelelo
Kwimveliso yesinyithi kunye nokuvelisa,I-MFDC (i-Medium Frequency Direct Direct Current) abashiseli bamabalazisetyenziswa ngokubanzi ukusebenza kwazo okuphezulu kunye nokusebenza okuchanekileyo kwe-welding. Nangona kunjalo, ukuwelda okungeyonyani{1}} ngumba oxhaphakileyo kwimisebenzi eyenziwayo{2}}ayichaphazeli kuphela umgangatho wemveliso kodwa inokubangela umngcipheko kwiinkqubo zemveliso ezilandelayo kunye nokhuseleko. Eli nqaku liphonononga iindlela ezisebenzayo zokujongana ne-welding yobuxokiAbashiseli bamabala beMFDC.
Ukuchonga i-Welding yobuxoki
- Isinyathelo sokuqala ekusombululeni i-welding yobuxoki kukuchongwa ngokuchanekileyo. Ukuwelda okungeyonyani kuhlala kubonakala njengoqhagamshelo olungaphezulu kwindawo ye-weld, kodwa ngaphandle kwebhondi yentsimbi eyomeleleyo, inokwahlukana ngokulula ekudibaneni kokukhanya. Oku kunokubangelwa ukungonelanga kwe-welding current, ixesha elifutshane kakhulu le-welding, uxinzelelo lwe-electrode olunganelanga, okanye ukucoceka komgangatho ophantsi kwezinto.
Ukulungelelanisa iiParameters ze-Welding
- Okwangoku kunye nexesha: Lungisa i-welding yangoku kunye nexesha ngokufanelekileyo ngokusekelwe kwiipropati eziphathekayo kunye nobukhulu. Ixesha eliphantsi kakhulu okanye ixesha elifutshane kakhulu kunokukhokelela kwi-welding eyaneleyo, okukhokelela kwi-welding yobuxoki.
- Uxinzelelo lwe-Electrode: Ukwandisa uxinzelelo lwe-electrode ngokufanelekileyo ukuze kuqinisekiswe indawo yoqhagamshelwano eyaneleyo kunye nokunyanzeliswa phakathi kwe-electrode kunye ne-workpiece, ukukhuthaza ukuqhutyelwa okufanayo kunye nokubunjwa kwe-nugget.
Ukuphucula iimeko zoMphezulu weMathiriyeli
- Ukucoca Unyango: Coca ngokucokisekileyo umphezulu we-workpiece phambi kokuba welding ukususa amabala e-oyile, ii-oxides, kunye nobunye ukungcola. Oku kuphucula i-welding yangoku yokuqhuba kakuhle kwaye kunciphisa umngcipheko we-welding yobuxoki.
- Unyango olungaphezulu: Kwimathiriyeli ethile, njengentsimbi engatyiwa okanye ialluminiyam, unyango lwekhemikhali, ukuqhunyiswa kwesanti, okanye ukucola kunokuphucula iimeko zomphezulu kwaye kuphucule ukomelela kwe-weld.
Ukuhlola kunye nokutshintshwa kwee-Electrodes
- Ukuhlolwa kwe-Electrode Wear: Jonga rhoqo i-electrode yokugqoka. Ii-electrode ezinxitywe kakhulu azichaphazeli kuphela ukuqhutywa kwangoku kodwa zinokubangela ukuhanjiswa koxinzelelo olungalinganiyo, okukhokelela kwi-welding yobuxoki. Ukutshintshwa kwangexesha kwee-electrode ezigugileyo kubalulekile ekuthinteleni ukuwelda okungeyonyani.
- Ukulungiswa kweMilo ye-Electrode: Lungisa imilo ye-electrode kunye nobukhulu ngokweemfuno ze-welding ukuqinisekisa ukusabalalisa okufanayo kwangoku kunye noxinzelelo ngexesha lenkqubo ye-welding.
Ukuqiniswa koQeqesho kunye neMigangatho yokuSebenza
- Uqeqesho lobuNgcali: Ukubonelela abaqhubi ngoqeqesho lobuchwephesha ukuqinisekisa ukuba banobuchule obuchanekileyo bokuwelda kwaye baqonde iimpawu zokuwelda kunye neemfuno zezinto ezahlukeneyo.
- ImiGangatho yokuSebenza: Ukuseka kunye nokunyanzeliswa kwemigangatho yokusebenza kwe-welding engqongqo ukuqinisekisa ukuba inyathelo ngalinye lihlangabezana neenkcukacha, ukunciphisa i-welding yobuxoki ebangelwa yimiba yabantu.
Ngamafutshane, ukujongana ne-welding yobuxokiAbashiseli bamabala beMFDCifuna indlela-eneenkalo ezininzi, kuqukwa uhlengahlengiso lweeparamitha ze-welding, ukulungelelanisa iimeko zomphezulu wemathiriyeli, ukuhlola kunye nokutshintshwa kwee-electrodes, kunye nokomeleza uqeqesho kunye nemigangatho yokusebenza. Ngokuphumeza le milinganiselo, umgangatho we-welding unokuphuculwa kakhulu, ukutshitshiswa kobuxoki kuncitshiswe, kunye nomgangatho wemveliso kunye nokusebenza kokhuseleko kuqinisekiswa.
