Kwi-welding ye-nut projection welding, akuqhelekanga ukuba iindawo ze-weld zibonise umbala ophuzi emva kwenkqubo ye-welding.Eli nqaku lijongene nezizathu ezibangela i-yellowing phenomenon kwaye libonelela ngezisombululo zokunciphisa lo mbandela, ukuqinisekisa ukuveliswa kwee-welds eziphezulu.
Izinto ezibangela ukuba zibe mthubi:
- I-Oxidation: Umbala ophuzi ungenzeka ngenxa ye-oxidation yendawo ye-weld ngexesha lenkqubo ye-welding.Izinto ezifana nokungonelanga kokukhusela igesi okanye ukucocwa ngokungafanelekanga kwendawo yokusebenza kunokukhokelela ekwandeni kokuvezwa kweoksijini, okukhokelela kwi-oxidation.
- Ukungcoliswa: Ubukho bezinto ezingcolileyo, ezifana ne-oyile, igrisi, okanye i-coatings engaphezulu kwi-workpiece okanye i-nut, inokufaka isandla kwi-yellowing ye-weld spots.Ezi zingcolisi zinokungena kwi-thermal degradation ngexesha lenkqubo ye-welding, ekhokelela kumbala.
- Ubushushu obugqithisileyo: Ukufakwa kobushushu obugqithisileyo okanye ixesha elide le-welding nako kunokubangela ukujika kombala weendawo ze-weld.Ukushisa ngokugqithiseleyo kunokubangela ukubunjwa kwe-intermetallic compounds okanye utshintsho kwi-microstructure, ekhokelela ekubonakaleni okuphuzi.
Izisombululo zokujongana noMthubi:
- Ukucoca ngokufanelekileyo: Coca ngokucokisekileyo i-workpiece kunye nomphezulu we-nut phambi kwe-welding ukususa nayiphi na into engcolileyo.Sebenzisa iindlela ezifanelekileyo zokucoca, ezifana nokucoca okanye ukucocwa kwe-solvent, ukuqinisekisa indawo ecocekileyo kunye neyokungcolisa.
- IGesi yoKhuseleko olwaneleyo: Qinisekisa ukhuseleko olwaneleyo lwegesi ngexesha lenkqubo ye-welding ukunciphisa ukuvezwa kwe-oksijini ye-atmospheric.Oku kunokufezekiswa ngokulungelelanisa umyinge wokuhamba kwerhasi, ukukhulisa indawo yomlomo wombhobho, okanye ukusebenzisa iikomityi zerhasi okanye iilaphu zokukhusela irhasi.
- Lungiselela iiParameters zeWelding: Lungisa iiparamitha ze-welding, njengangoku, i-voltage, kunye nexesha le-welding, ukufezekisa ibhalansi efanelekileyo phakathi kwegalelo lobushushu kunye nomgangatho we-weld.Gwema ubushushu obugqithisileyo obunokukhokelela ekutshintsheni kombala ngokulungisa iiparamitha ngokusekelwe kuhlobo lwezinto eziphathekayo kunye nobukhulu.
- Vavanya Ukuhambelana kwezinto: Qinisekisa ukuhambelana phakathi kwezinto zokusebenza, izinto ze-nut, kunye naluphi na iingubo ezingaphezulu.Izinto ezingahambelaniyo okanye iingubo zokwaleka zingafumana iimpendulo ezingathandekiyo ngexesha le-welding, ekhokelela kumbala.Khetha izinto ezihambelanayo okanye ucinge ngokususa iingubo ezingahambelaniyo phambi kwe-welding.
- Ukucocwa kwe-Post-Weld: Emva kokugqiba inkqubo ye-welding, yenza ukucocwa kwe-post-weld ukususa nayiphi na i-residu ye-flux okanye i-spatter enokuthi ifake isandla ekutshintsheni umbala.Sebenzisa iindlela ezifanelekileyo zokucoca ezisekelwe kwiimfuno ezithile zesicelo.
Ubutyheli bamachokoza e-weld kwi-welding ye-nut projection welding ingabalelwa ku-oxidation, ungcoliseko, okanye ubushushu obugqithisileyo.Ngokuphumeza iindlela zokucoca ezifanelekileyo, ukuqinisekisa ukukhuseleka okwaneleyo kwegesi, ukulungelelanisa iiparamitha ze-welding, ukuvavanya ukuhambelana kwezinto eziphathekayo, kunye nokwenza ukucoca emva kwe-weld, abavelisi banokunciphisa ngokufanelekileyo umba we-yellowing kunye nokufezekisa i-welds ephezulu.Ukujongwa rhoqo kwenkqubo ye-welding kunye nokuthotyelwa kweendlela ezilungileyo kuya kunceda ukuqinisekisa ukubonakala kwe-weld kunye nomgangatho wemveliso jikelele.
