I-Deformation yinkxalabo eqhelekileyo kwi-welding ye-nut spot, apho amacandelo adityanisiweyo anokuthi enze utshintsho olungafunekiyo lwemilo ngenxa yezinto ezahlukeneyo.Eli nqaku ligocagoca ngezizathu ezibangela i-welding-induced deformation kwaye inika izisombululo ezisebenzayo zokunciphisa lo mba.
- Ukugxininiswa kobushushu: Enye yezona zizathu eziphambili zokuguquka kwi-welding ye-nut spot kugxininiso lobushushu kwiindawo zendawo ngexesha lenkqubo ye-welding.Ubushushu obugqithisileyo bunokukhokelela ekwandeni kwe-thermal, okukhokelela ekujikeni okanye ukugoba kwe-workpiece.
- IiParameters ze-Welding ezingahambelaniyo: Iiparamitha ze-welding ezingafanelekanga okanye ezingahambelaniyo, ezifana nokugqithiswa kwe-welding yangoku okanye ixesha elide le-welding, kunokufaka isandla ekufudumeni okungalinganiyo kunye nokuguqulwa okulandelayo kweengxenye ezidibeneyo.Iiparamitha ezilinganisiweyo ngokufanelekileyo ziyimfuneko ukuphumeza ukusabalalisa ubushushu obulinganayo.
- Iipropathi zeMpahla yeMpahla yoMsebenzi: Izixhobo ezahlukeneyo zineendlela ezahlukeneyo zokufudumeza kunye nokwandiswa kwee-coefficients, ezinokuphembelela ukuba buthathaka kwazo kwi-deformation ngexesha le-welding.Ukudityaniswa kwezinto ezingafaniyo kunokunyusa ingxaki yokuguqulwa.
- Ukulungiswa okungonelanga: Ukulungiswa okungonelanga okanye ukugoba okungafanelekanga kwezinto zokusebenza kunokukhokelela ekuhambeni okugqithiseleyo ngexesha le-welding, kubangele ukungahambi kakuhle kunye nokuguqulwa.
- Uxinzelelo lwe-Welding olungalinganiyo: Ukuhanjiswa koxinzelelo olungafaniyo ngexesha le-welding yendawo kunokubangela ukudibanisa okungalinganiyo kunye negalelo kwi-deformation, ngakumbi kwizinto ezincinci okanye ezithambileyo.
- Uxinzelelo lweResidual: Uxinzelelo lwe-Welding-induced residual stress kwingingqi edibeneyo inokufaka isandla kwi-deformation.Olu xinzelelo lwangaphakathi lunokuthi luphumle ngokuhamba kwexesha, lubangele ukuba i-workpiece ijike okanye igqwethe.
- Izinga lokupholisa: Izinga lokupholisa ngokukhawuleza okanye elingalawulekiyo emva kwe-welding kunokubangela ukutshatyalaliswa kwe-thermal, okukhokelela kwi-deformation kwindawo edibeneyo.
Ukujongana noGuquko: Ukunciphisa i-deformation kwi-nut spot welding, amanyathelo amaninzi anokuphunyezwa:
a.Lungiselela i-Welding Parameters: Misa ngokucokisekileyo kwaye ulawule iiparitha ze-welding, ukuqwalasela izinto eziphathekayo kunye nokucwangciswa ngokubambisana, ukufezekisa ukusabalalisa ukushisa okufanayo.
b.Sebenzisa i-Fixturing eyiyo: Qinisekisa ukuba ii-workpieces ziqiniswe ngokukhuselekileyo kwaye zilungelelaniswe ngokufanelekileyo ngexesha le-welding ukunciphisa ukunyakaza kunye nokuguqulwa.
c.Ukulawula uxinzelelo lwe-Welding: Gcina uxinzelelo lwe-welding oluhambelanayo kunye olufanelekileyo ukuze ufezekise i-welds efanayo kunye nezinzile.
d.Ukushisa kwangaphambili okanye unyango lwasemva kobushushu: Cinga ngokufudumeza okanye unyango lokutshisa emva kwe-weld ukukhulula uxinzelelo olushiyekileyo kunye nokunciphisa umngcipheko wokuguqulwa.
e.Ukupholisa okuLawulwayo: Sebenzisa iindlela zokupholisa ezilawulwayo ukuthintela utshintsho olukhawulezayo lwe-thermal kunye nokunciphisa ukuguquka.
Utshintsho kwi-welding ye-nut spot ingabalelwa kwizinto ezinjengoxinzelelo lobushushu, iiparamitha ze-welding ezingahambelaniyo, iipropathi zezinto eziphathekayo, ukulungiswa, uxinzelelo lwe-welding, uxinzelelo olushiyekileyo, kunye nesantya sokupholisa.Ngokuqonda ezi zizathu kunye nokwamkela amanyathelo afanelekileyo, njengokuphucula iiparamitha ze-welding, ukusebenzisa ukulungiswa okufanelekileyo, kunye nokusebenzisa ukupholisa okulawulwayo, abaqhubi banokunciphisa ngokufanelekileyo imiba ye-deformation, ukuvelisa i-welds ezikumgangatho ophezulu kunye nokuphazamiseka okuncinci kunye nokufezekisa iziphumo ezinqwenelekayo kwizicelo ezahlukeneyo.
