Ngaba i-Thermal Equilibrium ithathelwa ingqalelo kwi-Medium-Frequency Direct Direct Spot Welding?

Kwihlabathi le-welding, zininzi izinto eziza kudlala ukuqinisekisa umgangatho kunye nokuthembeka kwemveliso yokugqibela. Enye into enjalo kukuqwalaselwa kwe-thermal equilibrium kwi-medium-frequency ngqo ngoku welding yendawo. Kule nqaku, sihlolisisa ukubaluleka kokulingana kwe-thermal kule nkqubo ye-welding kunye nefuthe layo kwi-weld yokugqibela.

Ukuwelda indawo ephakathi, edla ngokubizwa ngokuba yi-MFDC, bubuchule obusetyenziswa kakhulu kumashishini ahlukeneyo, kubandakanya iimoto, i-aerospace, kunye nokuvelisa. Ibandakanya ukudibanisa iziqwenga ezibini zetsimbi ngokufaka umsinga wombane kwi-frequency ephakathi, phakathi kwe-1000 Hz kunye ne-10000 Hz, ngokusebenzisa i-electroy alloy electrode. Umsinga wombane uvelisa ubushushu, obunyibilikisa isinyithi kwindawo ye-welding, kwaye ekupholiseni, i-weld eqinile yenziwa.

Olunye uqwalaselo olusisiseko kule nkqubo kukufumana ukulingana kwe-thermal. I-equilibrium ye-Thermal ibhekisela kwimeko apho igalelo lokushisa kwi-workpiece lilinganiswe ngokulahleka kobushushu, okubangelwa ukushisa okuzinzileyo kunye nokulawulwayo ngaphakathi kwendawo ye-welding. Ukufezekisa ukulingana kwe-thermal kubalulekile ngenxa yezizathu ezininzi:

1. Ukungqinelana kunye noMgangatho: I-Welding kwiqondo lokushisa elizinzile iqinisekisa i-welds ehambelanayo kunye nekhwalithi ephezulu. Ukushisa okungahambelaniyo kunokukhokelela kwiziphene ezifana ne-porosity, ukuqhekeka, okanye ukungena ngokwaneleyo.
2. IiPropathi zokuWeld ezifanelekileyo: Izinto ezahlukeneyo zifuna amaqondo okushisa athile e-welding ukufezekisa izinto ezifunwayo zoomatshini. I-equilibrium ye-thermal ivumela ulawulo oluchanekileyo lwegalelo lokushisa, ukuqinisekisa ukuba i-weld yokugqibela inamandla afunekayo kunye nokuqina.
3. Ukugqwesa okuNcitshisiweyo: I-Welding inokubangela ukuphazamiseka kwindawo yokusebenza ngenxa yokufudumeza okungalinganiyo kunye nokupholisa. I-equilibrium ye-Thermal inceda ukunciphisa ukugqwesa, iqinisekisa ukuba imveliso yokugqibela igcina imilo ejoliswe kuyo kunye nemilinganiselo.
4. Ukusebenza kakuhle kwamandla: I-Welding kwiqondo lokushisa elifanelekileyo kunciphisa ukusetyenziswa kwamandla kwaye kunciphisa inkunkuma yezinto eziphathekayo. Iinkqubo ze-welding ezingasebenziyo zinokubangela ukunyuka kweendleko zamandla kunye nokulahlekelwa kwezinto eziphathekayo.

Ukufikelela kwi-equilibrium ye-thermal kwi-MFDC welding spot ibandakanya ukulawulwa ngononophelo kweeparamitha ezahlukeneyo, kubandakanya okwangoku, umbane, ixesha le-welding, kunye namandla e-electrode. Iinkqubo zokubeka iliso lobushushu kunye neendlela zempendulo zihlala zisetyenziselwa ukugcina ubushushu obuhambelanayo kuyo yonke inkqubo ye-welding.

Uyilo lomatshini wokuwelda lukwadlala indima ebalulekileyo ekufezekiseni ukulingana kwe-thermal. Iindlela ezifanelekileyo zokutshatyalaliswa kobushushu, ukupholisa i-electrode efanelekileyo, kunye nokulawulwa ngokuchanekileyo kweeparamitha ze-welding ziyimfuneko ukuze kuqinisekiswe ukushisa okuzinzile kunye nokulawulwayo.

Ukuqukumbela, i-thermal equilibrium yingqwalasela ebalulekileyo kwi-medium-frequency ngqo ngoku welding yendawo. Ichaphazela ngokuthe ngqo umgangatho, ukuhambelana, kunye nokusebenza kakuhle kwenkqubo ye-welding. Iinjineli ze-welding kunye nabaqhubi kufuneka babeke iliso ngononophelo kwaye balawule iiparamitha ezahlukeneyo ukufezekisa nokugcina ukulingana kwe-thermal, ukuqinisekisa ukuba i-weld yokugqibela ihlangabezana nemigangatho efunekayo kunye neenkcukacha.
