Ukutyhelwa kweendawo ze-Weld kwi-Nut Projection ye-Welding kunye ne-Remedial Measures?

Kwi-welding ye-nut projection welding, akuqhelekanga ukuba iindawo ze-weld zibonise umbala ophuzi emva kwenkqubo ye-welding. Eli nqaku lijongana nezizathu ezibangela i-yellowing phenomenon kwaye libonelela ngezisombululo zokunciphisa lo mbandela, ukuqinisekisa ukuveliswa kwee-welds eziphezulu.

Izinto ezibangela ukuba zibe mthubi:

  1. 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.
  2. 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.
  3. 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:

  1. 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.
  2. 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.
  3. 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 umbala ngokulungisa iiparamitha ngokusekelwe kuhlobo lwempahla kunye nobukhulu.
  4. 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.
  5. 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 nut projection welding ingabalelwa ku-oxidation, ungcoliseko, okanye ubushushu obugqithisileyo. Ngokuphumeza iindlela zokucoca ezifanelekileyo, ukuqinisekisa ukukhuseleka okwaneleyo kwegesi, ukulungelelanisa iiparitha ze-welding, ukuvavanya ukuhambelana kwezinto eziphathekayo, kunye nokwenza ukucoca emva kwe-weld, abavelisi banokunciphisa ngokufanelekileyo umba we-yellowing kwaye bafezekise umgangatho ophezulu we-welds. Ukujongwa rhoqo kwenkqubo ye-welding kunye nokuthotyelwa kweendlela ezilungileyo kuya kunceda ukuqinisekisa ukubonakala kwe-weld kunye nomgangatho wemveliso jikelele.
