Ubungqina obucacileyo: Iinverter spot welders zisetyenziswa kakhulu kumashishini ahlukeneyo ngokusebenza kwazo okuphezulu kunye nomgangatho olungileyo wewelding.Nangona kunjalo, ukuqonda inkqubo yokuwelda kwaba matshini kunokuba lucelomngeni.Kweli nqaku, siza kuxubusha inkqubo ye-welding ye-welders ye-medium frequency inverter spot welders ukusuka kwiimbono ezimbini ezahlukeneyo, kubandakanywa imbono yombane kunye nembono ye-thermal.
Intshayelelo:
Iinverter spot welders eziphakathi zisetyenziswa kakhulu kushishino lokuvelisa ukusebenza kwazo okuphezulu kunye nomgangatho olungileyo wokuwelda.Nangona kunjalo, inkqubo yokuwelda kwaba matshini inokuntsonkotha kwaye kube nzima ukuyiqonda.Kweli nqaku, siza kuphonononga inkqubo ye-welding ye-welding ye-medium frequency inverter spot welders ukusuka kwiimbono ezimbini ezahlukeneyo, imbono yombane kunye nembono ye-thermal.
Imbonakalo yoMbane:
Inkqubo ye-welding ye-medium frequency inverter spot welder ixhomekeke kakhulu kwiipropati zombane zomatshini.I-welder yenza i-high frequency current ethi idluliselwe kwi-electrodes ye-welding kunye ne-workpiece.Ikhoyo ngoku ihamba nge-workpiece, ivelisa ubushushu kwaye yenza i-weld.Inkqubo ye-welding inokwahlulwa ibe ngamanqanaba amathathu: isigaba sokukhama, isigaba se-welding, kunye nesigaba sokubamba.
Kwinqanaba lokucudisa, i-electrodes ye-welding ifaka uxinzelelo kwi-workpiece, idibanisana.Eli nqanaba libaluleke kakhulu njengoko liqinisekisa ukuba i-workpiece ibekwe ngokufanelekileyo kwaye ibanjwe ngexesha lenkqubo ye-welding.
Kwinqanaba le-welding, i-frequency frequency current igqithiswa kwi-electrodes kunye ne-workpiece, ivelisa ubushushu kunye nokunyibilika kwe-workpiece.Ubushushu buveliswa ngenxa yokuchasana kwe-workpiece yokuhamba kwangoku.Umsinga usetyenziselwa ixesha elithile kunye nobukhulu obuthile bokuqinisekisa ukunyibilika okufanelekileyo kunye ne-welding.
Kwinqanaba lokubamba, i-current ivaliwe, kodwa i-electrodes ye-welding iyaqhubeka nokufaka uxinzelelo kwi-workpiece.Eli nqanaba livumela i-weld ukuba ipholile kwaye iqiniswe, iqinisekisa i-weld eqinile kunye neyomelele.
Imbonakalo yoThermal:
Inkqubo ye-welding ye-medium frequency inverter spot welder iphinda iphenjelelwe ziipropati zokushisa.Ubushushu obuveliswayo ngexesha le-welding kulawulwa zizinto ezahlukeneyo, kubandakanywa okwangoku, uxinzelelo lwe-electrode, kunye nexesha le-welding.
Ngethuba lenkqubo ye-welding, ukushisa okwenziwa ngoku kubangelwa ukuba i-workpiece yandise kwaye inkontileka.Ukwandiswa kwe-thermal kunye ne-contraction ye-workpiece inokuchaphazela umgangatho we-weld kwaye ikhokelela ekuphazamiseni okanye ekuqhekekeni.
Ukuthintela le miba, iiparitha ze-welding kufuneka zilawulwe ngokucophelela ukuze kuqinisekiswe ubungakanani obufanelekileyo bobushushu obuveliswayo kwaye busetyenziswe kwi-workpiece.Ukongezelela, ukusetyenziswa kwamanzi okupholisa kunye nokugcinwa ngokufanelekileyo kwe-electrode kunokunceda ukulawula ukushisa okwenziwa ngexesha lokutshisa kunye nokukhusela ukugqithiswa kwee-electrodes.
Isiphelo:
Ukuqukumbela, inkqubo yewelding ye-medium frequency inverter spot welders intsonkothile kwaye inokuba ngumngeni ukuyiqonda.Ngokuphonononga inkqubo kwiimbono zombini zombane kunye ne-thermal, sinokufumana ukuqonda okungcono kwezinto ezichaphazela umgangatho we-weld.Ukulawulwa ngokufanelekileyo kweeparamitha ze-welding kunye nokugcinwa kwezixhobo kubalulekile ekuqinisekiseni i-welds ephezulu kunye neyomelele.
