Sesebediswa sa Li-electrode tsa Mochini oa Welding oa Nut Spot ke eng?

Spot Welding ke mokhoa o tloaelehileng oa tlhahiso, o sebelisetsoang ho kopanya likarolo tse peli kapa ho feta tsa tšepe hammoho ka ho qhibilihisa mapheo a tsona le ho a kopanya. Mechini ea ho cheselletsa linate ke mofuta o ikhethileng oa lisebelisoa tsa ho tjheseletsa matheba tse etselitsoeng ho hokela linate kapa li-fasteners tse ling tse kentsoeng likarolong tsa tšepe. Mechini ena e sebelisa li-electrode tse khethehileng, 'me khetho ea lisebelisoa tsa elektrode ke ntlha ea bohlokoa ts'ebetsong ea bona.

Lisebelisoa tsa li-electrode tse sebelisoang mecheng ea li-welding tsa linate li ka ama haholo boleng le ho tšoarella ha li-welds. Ka tloaelo, li-electrode bakeng sa li-welding tsa linate li entsoe ka thepa e fanang ka motlakase o motle, ho hanyetsa mocheso o phahameng, le ho tšoarella. Ha re shebeng ka botebo lisebelisoa tse ling tse tloaelehileng tsa li-electrode tse sebelisoang mochining oa ho cheselletsa linate:

1. Lisebelisoa tsa Koporo: Koporo le li-alloys tsa eona, tse kang koporo-chromium le koporo-zirconium, li sebelisoa haholo bakeng sa lisebelisoa tsa electrode. Copper e fana ka conductivity e ntle ea motlakase le ho hanyetsa mocheso, ho e etsa hore e tšoanele mocheso o phahameng o hlahisoang nakong ea ho cheselletsa letheba. Li-electrode tsa koporo li boetse li bontša khanyetso e ntle ea ho apara, e leng ea bohlokoa bakeng sa nako e telele ea thepa.
2. Lisebelisoa tsa Copper Tungsten: Tungsten ea koporo ke thepa e kopantsoeng e kopanyang motlakase oa motlakase oa koporo le ho hanyetsa mocheso le ho tšoarella ha tungsten. Ke khetho e ntle bakeng sa lits'ebetso moo ho amehang lipotoloho tse phahameng tsa hajoale le tse pheta-phetoang. Li-electrode tsa copper tungsten li ka mamella ts'ebeliso ea nako e telele ntle le ho senyeha ho hoholo.
3. Molybdenum: Li-electrode tsa Molybdenum li tsejoa ka ho hanyetsa mocheso o phahameng le bokhoni ba ho boloka sebōpeho sa tsona tlas'a mocheso o feteletseng. Le hoja li ka 'na tsa se ke tsa tsamaisa motlakase joaloka koporo, li ntse li loketse lisebelisoa tse itseng tsa ho cheselletsa libaka, haholo-holo tse amanang le lisebelisoa tse sa tloaelehang kapa moo mocheso o feteletseng o hlahisoang teng.
4. Sehlopha sa 2 Koporo: Li-electrode tsa koporo tsa Sehlopha sa 2 ke khetho e theko e tlaase bakeng sa mochini oa ho tjheselletsa linate. Le hoja li se na boemo bo lekanang ba ho hanyetsa mocheso joaloka li-alloys tsa koporo kapa tungsten ea koporo, li ntse li khona ho fana ka li-welds tse ntle lits'ebetsong tse ngata.

Ho khetha thepa e nepahetseng ea eleketrode bakeng sa mochini oa ho tjheseletsa linate letheba ho ipapisitse le lintlha tse 'maloa, ho kenyelletsa le mofuta oa lisebelisoa tse cheselitsoeng, boleng bo hlokahalang ba li-welds, le bophahamo bo lebelletsoeng ba tlhahiso. Li-alloys tsa koporo le tungsten ea koporo hangata ke likhetho tse holimo ka lebaka la litšobotsi tsa tsona tse phahameng tsa ts'ebetso, empa khetho e ka fapana ho latela litlhoko tse itseng.

Qetellong, lisebelisoa tsa li-electrode tse sebelisoang mecheng ea ho cheselletsa linate ke ntho ea bohlokoa ho fihlela li-welds tsa boleng bo holimo le tse tšoarellang. Khetho ea thepa e itšetlehile ka lintlha tse kang conductivity ea motlakase, ho hanyetsa mocheso, le ho apara ho hanyetsa. Bahlahisi ba tlameha ho nahana ka hloko litlhoko tsa bona tse khethehileng tsa ho tjheseletsa ho khetha thepa e loketseng ka ho fetisisa ea li-electrode bakeng sa mechini ea bona ea ho cheselletsa linate.
