Ubudlelwane phakathi kweResistance Spot Welding Time kunye ne-Electrode Displacement

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.
