Intshayelelo
Kwimveliso yanamhlanje,I-MFDC (i-Medium Frequency Direct Direct Current) abashiseli bamabalaibe lolona khetho lufanelekileyo lokuwelda ngokufanelekileyo nangokuchanekileyo amandongomane kwizixhobo zokusebenza zetsimbi ngenxa yokusebenza kwazo okuphezulu. Eli nqaku libonelela ngohlalutyo olubanzi lwenkqubo ye-nut welding kunye nendlela yokusebenzisaAbashiseli bamabala beMFDC, inika abafundi ulwazi oluneenkcukacha kobu buchule bokuwelda obuphezulu-.
1. Ukulungiselela inkqubo
Ukulungiswa ngokucokisekileyo kubalulekile ukuqinisekisa umgangatho we-welding. Ngaphambi kwe-welding, hlambulula amantongomane kunye neendawo zokudibanisa ukususa ioli, i-oxides, kunye nezinye izinto ezingcolileyo, ukuphucula umgangatho wendawo yokudibanisa. Ukongeza, hlola i-MFDC i-welder yendawo kunye nezixhobo zayo, ezifana ne-electrode kunye neenkqubo zokupholisa, ukuqinisekisa ukuba isixhobo sikwimeko efanelekileyo yokusebenza. Ngokusekwe kwisixhobo se-nut, ubungakanani, kunye neemfuno zomsebenzi, khetha iiparamitha ezifanelekileyo ze-welding, kubandakanya i-welding yangoku, ixesha kunye noxinzelelo.
2. UkuKhethwa kwe-Electrode kunye nokumiswa
I-Electrodes zizinto ezibalulekileyo kwinkqubo ye-welding. Ukukhethwa kobume be-electrode kunye nobukhulu kubalulekile ukuqinisekisa uqhagamshelwano olulungileyo kunye ne-nut kunye nokusebenzisa uxinzelelo olufanayo. Ngaphambi kwe-welding, beka i-nati kwindawo echazwe kwangaphambili kwaye usebenzise i-clamps okanye izixhobo zokubeka ukuze uyikhusele ngokuqinileyo kwimisebenzi elandelayo.
3. Izicwangciso zeParameter yeWelding
Iiparamitha ze-Welding zichaphazela ngokuthe ngqo umgangatho we-welding. Lungisa ngokuchanekileyo i-welding yangoku, ixesha, kunye noxinzelelo olusekwe kwiipropathi zezinto eziphathekayo, ubukhulu, kunye nemilinganiselo yeendongomane kunye nezixhobo zokusebenza. Ngokuqhelekileyo, i-welding current kufuneka ibe yimodareyitha ukuphepha ukushisa okanye ukungonelanga kwamandla. Ixesha le-welding kufuneka lilawulwe phakathi koluhlu olufanelekileyo ukuqinisekisa ukunyibilika okufanelekileyo kunye nokwakhiwa kwe-nugget ephezulu yekhwalithi. Ukongezelela, sebenzisa uxinzelelo olufanelekileyo lwe-welding ukuqinisekisa ibhondi eqinile phakathi kwe-nut kunye ne-workpiece, ukuphucula ukutywinwa kunye namandla okudibanisa.
4. Inkqubo yeWelding
Qala i-MFDC i-welder yendawo kwaye uqhube ukuwelda ngokuhambelana neeparamitha ezicwangcisiweyo. Ngethuba le-welding, i-electrode isebenzisa uxinzelelo kunye nangoku kwi-nut, ivelisa ukushisa okwaneleyo ukunyibilikisa i-welding point kwaye yenza i-nugget. Ixesha le-welding lifutshane kwaye kufuneka lilawulwe ngokungqongqo ukunqanda ukugqithisa okanye ukugqithisa. Lawula utshintsho kwindawo yokuwelda kwaye uhlengahlengise iiparamitha ngexesha lokwenyani-ukuqinisekisa umgangatho.
5. Ukupholisa kunye nokuqinisa
Emva kwe-welding, vumela ixesha elaneleyo lokuba indawo ye-welding iphole kwaye iqine. Ubude bexesha lokupholisa buxhomekeke kwizinto eziphathekayo kunye nobukhulu ukuthintela ukuguqulwa kwe-thermal kunye ne-annealing. Gwema ukusebenzisa amandla angaphandle okanye ukwenza eminye imisebenzi ngexesha lokupholisa ukugcina amandla kunye nokuzinza komdibaniso.
6. Ukuhlolwa koMgangatho kunye naMaxwebhu
Ekugqibeleni, qhuba ukuhlolwa komgangatho kumanqaku e-welding, kubandakanywa ukujonga okubonakalayo kunye neemvavanyo zamandla. Qinisekisa ukuba iindawo zokuwelda zigudile, azinantandabuzo, iipores, kunye nezinye iziphene. Qinisekisa amandla adibeneyo ngeendlela zokuvavanya eziyingozi. Bhala iiparitha ze-welding kunye neziphumo zokuhlola ukuhlalutya kunye nokuphuculwa kwexesha elizayo.
Isishwankathelo, inkqubo ye-nut welding usebenzisaAbashiseli bamabala beMFDCibandakanya amanyathelo amaninzi kunye nobuchwepheshe obuphambili. Ngolungiselelo olucokisekileyo, useto oluchanekileyo lweparameter, ulawulo olungqongqo lwenkqubo, kunye nokuhlolwa okungqongqo komgangatho, abavelisi banokufikelela umgangatho ozinzileyo nothembekileyo we-welding, ukubonelela ngenkxaso eyomeleleyo kwimveliso yanamhlanje.
