Isingeniso
Ekwenziweni kwesimanje,Ama-spot welders e-MFDC (Medium Frequency Direct Current).sebeyinketho ekahle yokushisela amantongomane ngendlela ephumelelayo nenembile ezintweni zokusebenza zensimbi ngenxa yokusebenza kwazo okuphezulu. Lesi sihloko sinikeza ukuhlaziywa okuphelele kwenqubo yokushisela amantongomane kanye nendlela yokusebenzisaMFDC spot welders, enikeza abafundi imininingwane enemininingwane ngale ndlela yokushisela{0}}esebenza kahle kakhulu.
1. Ukulungiselela Inqubo
Ukulungiselela kahle kubalulekile ukuze kuqinisekiswe izinga lokushisela. Ngaphambi kokushisela, hlanza amantongomane nezindawo zokushisela ukuze ususe uwoyela, ama-oxide, nokunye ukungcola, uthuthukise ikhwalithi yendawo yokuxhumana. Ukwengeza, hlola i-MFDC spot welder kanye nezinsiza zayo, njengama-electrode nezinhlelo zokupholisa, ukuze uqinisekise ukuthi okokusebenza kusesimweni esikahle sokusebenza. Ngokusekelwe kumpahla yamantongomane, usayizi, kanye nezidingo zengcezu yokusebenza, khetha amapharamitha wokushisela afanelekile, okuhlanganisa wamanje wokushisela, isikhathi, nokucindezela.
2. Ukukhetha kanye nokuma kwe-Electrode
Ama-Electrode ayingxenye ebalulekile yenqubo yokushisela. Ukukhethwa komumo we-electrode nosayizi kubalulekile ukuze kuqinisekiswe ukuthintana kahle namantongomane futhi usebenzise ingcindezi efanayo. Ngaphambi kokushisela, beka inadi endaweni enqunywe kusengaphambili futhi usebenzise izinsimbi noma izinto zokubeka ukuze ulivikele liqine ukuze lisebenze ngokulandelayo.
3. Izilungiselelo zepharamitha yokushisela
Imingcele yokushisela ithinta ngqo ikhwalithi yokushisela. Lungisa kahle umshini wokushisela, isikhathi, nengcindezi ngokusekelwe ezintweni ezibonakalayo, ukujiya, nobukhulu bamantongomane nezingxenye zokusebenza. Ngokuvamile, i-welding current kufanele ibe ngokulinganisela ukugwema ukushisa ngokweqile noma amandla anganele. Isikhathi sokushisela kufanele silawulwe phakathi kwebanga elifanele ukuze kuqinisekiswe ukuncibilika okufanele kanye nokwakheka{3}kwekhwalithi ephezulu ye-nugget. Ukwengeza, sebenzisa ingcindezi efanele yokushisela ukuze uqinisekise isibopho esiqinile phakathi kwentongomane nesiqeshana sokusebenza, uthuthukise ukuvala nokuqina kwelunga.
4. Inqubo yokushisela
Qala i-MFDC spot welder bese ufaka i-welding ngokuya ngemingcele esethiwe. Ngesikhathi sokushisela, i-electrode isebenzisa ingcindezi kanye namanje ku-nati, ikhiqiza ukushisa okwanele ukuncibilikisa iphuzu lokushisela bese yenza i-nugget. Isikhathi sokushisela ngokuvamile sifushane futhi kufanele silawulwe ngokuqinile ukuze kuvinjelwe ukushisela ngokweqile noma ukushisela ngaphansi. Gada izinguquko endaweni yokushisela futhi ulungise amapharamitha ngesikhathi-sangempela ukuze uqinisekise ikhwalithi.
5. Ukupholisa kanye Nokuqinisa
Ngemva kokushisela, vumela isikhathi esanele ukuze indawo yokushisela iphole futhi iqine. Ubude besikhathi sokupholisa buncike ezintweni kanye nogqinsi ukuze kuvinjwe ukuwohloka kokushisa nokudonsa. Gwema ukusebenzisa amandla angaphandle noma ukwenza eminye imisebenzi phakathi nokupholisa ukuze ugcine amandla nokuzinza kwelunga.
6. Ukuhlolwa Kwekhwalithi kanye Nemibhalo
Okokugcina, yenza ukuhlolwa kwekhwalithi ezindaweni zokushisela, okuhlanganisa ukuhlola okubukwayo nokuhlolwa kwamandla. Qinisekisa ukuthi izindawo zokushisela zibushelelezi, azinayo imifantu, izimbotshana, nokunye ukonakala. Qinisekisa amandla ahlangene ngokusebenzisa izindlela zokuhlola ezilimazayo. Bhala phansi amapharamitha wokushisela kanye nemiphumela yokuhlolwa ukuze uhlaziye futhi uthuthuke esikhathini esizayo.
Kafushane, inqubo Welding nut usebenzisaMFDC spot welderskuhilela izinyathelo eziningi kanye nobuchwepheshe obubalulekile. Ngokulungiselela ngokucophelela, izilungiselelo ezifanele zepharamitha, ukulawulwa kwenqubo okuqinile, nokuhlolwa kwekhwalithi okuqinile, abakhiqizi bangafinyelela ikhwalithi yokushisela ezinzile nethembekile, banikeze ukwesekwa okuqinile kokukhiqizwa kwesimanje.
