Iiparamitha zexesha koomatshini bokuwelda beNut Spot?

Oomatshini bokuwelda bendawo ye Nut basebenzisa iiparamitha zexesha ezahlukeneyo ukulawula kunye nokwandisa inkqubo yokuwelda. Ezi parameters zexesha zidlala indima ebalulekileyo ekumiseni ubude kunye nokulandelelana kwezigaba ezithile ze-welding, ukuqinisekisa ukuveliswa kwee-welds ezikumgangatho ophezulu. Eli nqaku libonelela ngesishwankathelo sexesha eliphambili leeparamitha ezisetyenziswa koomatshini bokuwelda bamantongomane.

1. Ixesha langaphambi kwe-Weld: Ixesha elingaphambi kwe-weld libhekisela kwixesha ngaphambi kokuba inkqubo ye-welding iqale. Ngeli xesha, i-electrodes idibaniswa nomphezulu we-workpiece, ifake uxinzelelo lokuseka uqhagamshelwano olufanelekileyo lombane. Ixesha elingaphambi kwe-weld livumela ukuhlanganiswa kokudibanisa kunye nokususwa kwanoma yiyiphi i-surface contaminants okanye i-oxide layers.
2. Ixesha le-Weld: Ixesha le-weld limele ixesha apho i-welding yangoku ihamba ngee-electrodes, idala i-weld nugget. Ixesha le-weld lilawulwa ngononophelo ukufezekisa igalelo lobushushu elifunekayo kunye nokudibanisa phakathi kwe-nut kunye ne-workpiece material. Kuxhomekeke kwizinto ezifana nobukhulu bezinto eziphathekayo, uyilo oludibeneyo, kunye namandla afunekayo e-weld.
3. Ixesha le-Post-Weld: Emva kokuba i-welding current ivaliwe, ixesha le-post-weld libhekisela kwixesha apho uxinzelelo lugcinwe kwi-joint ukuvumela ukuqina kunye nokupholisa kwe-weld. Eli xesha ipharamitha iqinisekisa ukuba i-weld iqinisa ngokwaneleyo ngaphambi kokukhulula uxinzelelo. Ixesha le-post-weld lingahluka ngokuxhomekeke kwizinto eziphathekayo kunye neemfuno ezidibeneyo.
4. Ixesha le-Inter-Weld: Kwezinye izicelo apho i-welds ezininzi zenziwa ngokulandelelanayo, ixesha eliphakathi kwe-weld lingeniswa phakathi kwe-welds ngokulandelanayo. Eli xesha lokuphumla livumela ukutshatyalaliswa kobushushu, ukuthintela ukuqokelelwa kobushushu obugqithisileyo kunye nomonakalo onokuthi ube khona kwii-electrode okanye i-workpiece. Ixesha eliphakathi kwe-weld libalulekile ekugcineni iimeko ze-welding ezingaguqukiyo kuyo yonke inkqubo yemveliso.
5. I-Off-Time: I-off-time ibonisa ubude bexesha phakathi kokugqitywa komjikelo we-welding enye kunye nokuqaliswa kokulandelayo. Ivumela i-electrode repositioning, i-workpiece repositioning, okanye naluphi na uhlengahlengiso oluyimfuneko ngaphambi kokuqala umsebenzi olandelayo we-welding. I-off-time ibalulekile ekuqinisekiseni ukuhamba komsebenzi okufanelekileyo kunye nokulungelelaniswa phakathi kwe-electrode kunye ne-workpiece.
6. Ixesha lokuCima: Ixesha lokucinezela libhekisela kwixesha apho uxinzelelo lufakwe kwi-joint ngaphambi kokuba i-welding current iqaliswe. Eli xesha ipharamitha iqinisekisa ukuba i-electrode ibambe ngokuqinileyo i-workpiece kwaye iseke uqhagamshelwano olufanelekileyo lombane. Ixesha lokucudisa livumela ukususwa kwaso nasiphi na isithuba somoya okanye izitenxo zomhlaba, ukukhuthaza umgangatho we-weld ongaguqukiyo.

Iiparamitha zexesha zidlala indima ebalulekileyo ekulawuleni inkqubo ye-nut spot welding kunye nokufezekisa i-welds ekumgangatho ophezulu. Ixesha langaphambi kweweld, ixesha leweld, ixesha lasemva kweweld, ixesha eliphakathi kweweld, off-time, kunye nexesha lokucudisa aphakathi kwamaxesha angundoqo asetyenziswa kumatshini wokuwelda amandongomane. Ukulungelelaniswa okufanelekileyo kunye nokulungiswa kwezi parameters zexesha kuqinisekisa iziphumo ze-weld ezithembekileyo nezingaguqukiyo, kuthathelwa ingqalelo izinto ezifana noyilo oludibeneyo, iimpawu zezinto eziphathekayo, kunye neempawu ze-weld ezifunwayo. Ukuqonda kunye nokulawula ngokufanelekileyo ezi parameters zexesha negalelo ekusebenzeni ngokubanzi kunye nomgangatho wenkqubo ye-nut spot welding.
