Intshayelelo
Kwishishini lokulungisa isinyithi,I-MFDC (i-Medium Frequency Direct Direct Current) abashiseli bamabalaziye zaba zizixhobo eziphambili eziyimfuneko kwimigca emininzi yemveliso ngenxa yokusebenza kwazo ngokufanelekileyo nangokuzinzileyo. Nangona kunjalo, ukuqinisekisa ukuba umgangatho we-welding udibana nemigangatho ephezulu, kubalulekile ukuqonda amanqaku amaninzi angundoqo olawulo lomgangathoAbashiseli bamabala beMFDC. Eli nqaku liza kugxininisa kulo mxholo, lihlalutye kwezi ngongoma zibalulekileyo, kwaye linike izisombululo ezihambelanayo.
I. I-Welding Parameter Setting
Ukumisela iiparitha ze-welding yikhonkco ephambili ekulawuleni umgangatho we-welding. Oku kubandakanya ukulungelelanisa iiparamitha eziphambili ezifana ne-welding current, ixesha le-welding, kunye noxinzelelo lwe-electrode. Izicwangciso ezichanekileyo zeparameter ziqinisekisa igalelo lokushisa eliphakathi ngexesha lenkqubo ye-welding kunye nokwakhiwa kwe-uniform kunye ne-weld nugget eqinile kwi-joint. Ke ngoko, abaqhubi kufuneka babeke ngokuchanekileyo iiparamitha ze-welding ngokusekelwe kuhlobo, ubukhulu bezinto zetsimbi, kunye neemfuno ze-welding, kwaye baqinisekise ingqiqo yabo (ingqiqo / ukufaneleka) ngokuvavanya.
II. UkuKhethwa kwe-Electrode kunye noLondolozo
I-electrode, njengenxalenye yokunxibelelana ngokuthe ngqo ngexesha lenkqubo ye-welding, ichaphazela ngokuthe ngqo umgangatho we-welding. Ukukhetha izinto ezifanelekileyo ze-electrode, ezifana ne-chromium zirconium yethusi, inokubonelela nge-conductivity efanelekileyo kunye nokumelana nokugqoka. Ngexesha elifanayo, ukuhlola rhoqo kunye nokugcina i-electrodes, njengokucoca i-oxide layers kunye nokujonga ukunxiba, nazo ziyimilinganiselo ebalulekileyo yokuqinisekisa umgangatho ozinzileyo we-welding. Ii-electrode ezigugile kakhulu kufuneka zitshintshwe ngokukhawuleza ukunqanda ukuchaphazela umgangatho we-welding kunye nokusebenza kwezixhobo.
III. Unyango lwe Workpiece Surface
Ukunyangwa komphezulu we-workpiece phambi kwe-welding kubalulekile ngokulinganayo. Ukungcola okufana ne-oyile ye-oyile kunye nomhlwa kwindawo yokusebenza kunokuchaphazela ukuqhutyelwa kwe-welding yangoku kunye nokwakhiwa kwe-weld nugget, ngaloo ndlela ukunciphisa umgangatho we-welding. Ngoko ke, izinto zokusebenza kufuneka zicocwe kakuhle kwaye zonakaliswe phambi kokuba zitshiswe ukuze kuqinisekiswe indawo ecocekileyo, engcolisayo{2}}ekhululekileyo. Oku kunceda ukuphucula amandla kunye nokumelana nokubola kwe-welded joint.
IV. Ulawulo lweNdawo yokuwelda
Ummandla we-welding nawo unempembelelo ethile kumgangatho we-welding. Izinto zokusingqongileyo ezifana nobushushu, ukufuma, kunye nothuli kunokuchaphazela ukuzinza kwenkqubo ye-welding kunye nomgangatho we-welding joint. Ngoko ke, indawo ye-welding kufuneka ilawulwe ngokungqongqo ngexesha lenkqubo ye-welding, ukuqinisekisa ukuba i-welding yenziwa phantsi kweemeko ezifanelekileyo zokushisa kunye nomswakama. Kwangaxeshanye, gcina indawo yokusebenza icocekile kwaye ingena kakuhle{3}}ukunciphisa ukufumba kothuli kunye neegesi eziyingozi.
V. Ukubekwa esweni kweNkqubo yokuWelding
Ixesha lokwenyani{0}}lokujongwa kwenkqubo yewelding ikwayindlela ebalulekileyo yokuqinisekisa umgangatho wokuwelda. Ngokubeka esweni utshintsho kwiiparamitha ezinje nge-welding yangoku, i-voltage, kunye nobushushu, izinto ezingaqhelekanga ngexesha le-welding zinokubonwa kwaye zihlengahlengiswe ngokukhawuleza. Ngaphaya koko, ukusebenzisa izixhobo zokuwelda zangoku kunye neenkqubo zolawulo oluzenzekelayo zenza uhlengahlengiso oluzenzekelayo kunye nokulungiswa kweeparamitha ze-welding, ngakumbi ukomeleza uzinzo kunye nokuthembeka komgangatho we-welding.
VI. Thumela -Uhlolo kunye noVavanyo lweWeld
Ukuhlolwa kwe-weld - kunye novavanyo ngamanyathelo abalulekileyo ekuqinisekiseni ukuba umgangatho we-welding uyahlangabezana neemfuno. Iindlela ezinjengokuhlola okubonwayo kunye -novavanyo olungonakalisi (umzekelo, X-uvavanyo lweray, uvavanyo lwe-ultrasonic) lunokuvavanya ngokubanzi imeko yomgangatho wejoyini edityanisiweyo. Kwiziphene ezichongiweyo kunye neengxaki, kufuneka ziqwalaselwe kwaye zilungiswe ngokukhawuleza ukuqinisekisa ukuba umgangatho we-welding uhambelana nemigangatho efanelekileyo kunye neemfuno.
Isishwankathelo, amanqaku aphambili ekulawuleni umgangatho we-welding kwiAbashiseli bamabala beMFDCibandakanya ukusetwa kweparamitha ye-welding, ukhetho kunye nokugcinwa kwe-electrode, unyango lomphezulu we-workpiece, ulawulo lwendalo esingqongileyo, ukujongwa kwenkqubo ye-welding, kunye nokuhlolwa kwe-weld kunye nokuhlolwa kweposi. Kuphela ngokuqonda ngokupheleleyo la manqaku kunye nokwamkela izisombululo ezihambelanayo apho umgangatho we-welding uya kuqinisekiswa ukuhlangabezana nemigangatho ephezulu.
