Mokhoa oa ho khetha lisebelisoa tsa elektrode tsa mochini oa welding oa maqhubu a mahareng?

Mokhoa oa ho khetha lisebelisoa tsa elektrode tsa mochini oa welding oa maqhubu a mahareng?Spot tjheseletsa eleketrode hlooho ka hona joale ea likete ho mashome a likete tse amperes, mamella gagamalo ya 9.81 ~ 49.1MPa, hang-hang mocheso oa 600 ℃ ~ 900 ℃.Ka hona, electrode e hlokeha ho ba le motlakase o motle oa motlakase, mocheso oa mocheso, boima ba mocheso le khanyetso e phahameng ea ho senya.

Li-electrode tsa Spot welding li entsoe ka li-alloys tsa koporo.Bakeng sa ho ntlafatsa ts'ebetso ea li-electrode tsa alloy tsa koporo, hangata hoa hlokahala ho fumana kalafo e matlafatsang, joalo ka: ho matlafatsa ts'ebetso e batang, ho matlafatsa tharollo e tiileng, ho matlafatsa pula ea botsofali le ho matlafatsa ho hasana.Ts'ebetso ea electrode e boetse e fetoha ka mor'a phekolo e fapaneng ea ho matlafatsa.Ha lipoleiti tsa tšepe tse kentsoeng ka serame, lipoleiti tsa tšepe tse entsoeng ka masenke, tšepe e sa hloekang kapa lipoleiti tsa aluminium li hloka ho ts'oaroa ka matheba, lisebelisoa tse nepahetseng tsa li-electrode li lokela ho khethoa ho ea ka thepa ea lisebelisoa tsa poleiti.

Khetho ea lisebelisoa tsa electrode bakeng sa ho tjheseletsa letheba poleiti ea tšepe e lokela ho fokotsa letheba le deformation ea eleketrode nakong ea tjheseletsa ea letheba, e hlokang boima bo phahameng, conductivity e ntle ea motlakase le ea mocheso oa motlakase ka mocheso o phahameng, le tšekamelo e nyenyane ea alloying le zinki.

Bophelo ba li-electrode tsa galvanized steel plate welding le lisebelisoa tse 'maloa tsa li-electrode bo bolelele ho feta ba cadmium copper electrode.Hobane le hoja motlakase le mocheso oa motlakase oa koporo oa cadmium o molemo, ka kakaretso ho lumeloa hore ho khomarela zinki ho fokotsehile, empa ha e le hantle, ka lebaka la mocheso o fokolang o fokolang, phello ea boima bo phahameng ba mocheso o moholo.Boima ba mocheso o phahameng oa koporo ea zirconium bo phahame, kahoo bophelo ba eona le bona bo bolelele.Le hoja boima bo phahameng ba mocheso oa koporo ea daemane ea beryllium bo phahame, hobane conductivity ea eona e mpe haholo ho feta ea koporo ea chromium-zirconium, conductivity le conductivity ea mocheso li phetha karolo e kholo tšusumetsong ea bophelo ba eona, 'me bophelo ba eona ba electrode bo batla bo le tlaase.

Ho phaella moo, tšebeliso ea tungsten (kapa molybdenum) e kenyelelitsoeng motsoako oa li-electrode welding galvanized steel plate, bophelo ba eona bo boetse bo phahame, le hoja conductivity ea tungsten, molybdenum e le tlaase, hoo e ka bang 1/3 feela ea koporo ea chromium, empa mocheso oa eona o nolofatsang o phahame. (1273K), boima bo phahameng ba mocheso (haholo-holo tungsten), electrode ha e bonolo ho deformation.
