I-Resistance spot welding bubuchule obusetyenziswa kakhulu ekuveliseni, ngakumbi kumashishini eemoto kunye ne-aerospace, apho imfuneko yeewelds ezinamandla nezithembekileyo zibaluleke kakhulu. Le nkqubo ibandakanya ukusetyenziswa kwamandla ombane kunye noxinzelelo lokudibanisa iziqwenga ezimbini zetsimbi kunye. Enye ipharamitha ebalulekileyo kwindawo yokumelana ne-welding lixesha lokuwelda, elidlala indima ebalulekileyo ekumiseleni umgangatho kunye namandla e-weld. Kweli nqaku, siza kuphonononga ubudlelwane obuntsonkothileyo phakathi kwexesha le-welding kunye ne-electrode displacement, sikhanyisela izinto ezichaphazela oku kuguquguqukayo.
I-Resistance spot welding, edla ngokubizwa ngokuba yi-spot welding, yinkqubo yokudibanisa exhomekeke kwisicelo sasekhaya sobushushu obuveliswa kukuxhathisa kombane kwindawo yokudibanisa phakathi kwamaqhekeza amabini esinyithi. I-Electrodes isetyenziselwa ukufaka uxinzelelo kunye nangoku ukwenza i-weld nugget. Ubude bexesha lokuhamba kwangoku, elibizwa ngokuba lixesha le-welding, yinto ephambili kwimpumelelo yenkqubo ye-welding.
Ixesha le-Welding kunye neempembelelo zayo
Ixesha le-welding lichaphazela ngokuthe ngqo ubungakanani kunye nomgangatho we-weld nugget. Amaxesha amade e-welding akholisa ukukhokelela kwiiweld ezinkulu kunye nezandisiweyo, ngelixa amaxesha amafutshane avelisa iiweld ezincinci, ezingekho nzulu. Ubudlelwane phakathi kwexesha le-welding kunye nokufuduswa kwe-electrode yinkimbinkimbi kwaye kuxhomekeke kwizinto ezahlukeneyo, kubandakanya iipropathi zezinto eziphathekayo, ijometri ye-electrode, kunye ne-welding yangoku.
Izinto eziPhembelela i-Electrode Displacement
a. Ukutyeba kwezinto:Izixhobo ezityebileyo zifuna amaxesha amade e-welding ukuqinisekisa ukungena nokudityaniswa okufanelekileyo. Njengoko ixesha le-welding likhula, ukufuduka kwe-electrode kuyanda ukulungiselela ubushushu obongezelelweyo kunye noxinzelelo olufunekayo.
b. Amandla e-Electrode:Amandla asetyenziswa yi-electrode achaphazela ukufuduka kwe-electrode. Amandla aphezulu e-electrode angakhokelela kwintshukumo ekhawulezayo ye-electrode ngenxa yoxinzelelo olwandisiweyo, okukhokelela kumaxesha amafutshane welding.
c. Uyilo lwe-Electrode:Imilo kunye nobukhulu bee-electrode zidlala indima ebalulekileyo. Uyilo olwahlukileyo lwe-electrode lunokuba neziphumo ezahlukeneyo ekugxothweni kwe-electrode, nakwixesha elifanayo le-welding.
d. I-Welding yangoku:I-welding intensity yangoku ichaphazela isantya apho i-weld nugget ifom. Imisinga ephezulu ikhokelela ekufudukeni ngokukhawuleza kwe-electrode kunye namaxesha amafutshane welding.
Ukuqonda ubudlelwane phakathi kwexesha le-welding kunye nokufuduswa kwe-electrode kubalulekile ekufezekiseni i-welds engaguqukiyo kunye nomgangatho ophezulu. Abavelisi banokulawula olu lwalamano ngokulungelelanisa iiparitha ze-welding kunye nokukhetha ngokucophelela izinto ze-electrode kunye noyilo.
Kwindawo yokumelana ne-welding spot, ubudlelwane phakathi kwexesha le-welding kunye ne-electrode displacement yinto eguquguqukayo kwaye inamacala amaninzi. Njengoko siphononongile, izinto ezinjengobukhulu bezinto eziphathekayo, amandla e-electrode, uyilo lwe-electrode, kunye ne-welding yangoku zonke ziyadlala. Ukuqonda obu budlelwane kubalulekile ekuveliseni i-welds ethembekileyo neyomeleleyo kwizicelo ezahlukeneyo zemizi-mveliso. Abaphandi kunye neenjineli bayaqhubeka nokuphanda kunye nokucokisa olu nxibelelwano ukutyhala imida yento enokwenzeka kwihlabathi le-welding.
