Medium-frequency direct current (MFDC) spot welding ke mokhoa oa bohlokoa oa ho tjheseletsa o sebelisoang liindastering tse fapaneng, joalo ka likoloi, sefofane le tlhahiso. Ho netefatsa boleng ba li-welds ho bohlokoa haholo ho netefatsa boleng ba sebopeho le bophelo bo bolelele ba sehlahisoa sa ho qetela. Sehloohong sena, re tla tšohla lintlha tsa bohlokoa tsa tlhahlobo ea boleng ho MFDC welding spot.
1. Tlhahlobo ea Weld Seam:
E 'ngoe ea lintlha tsa mantlha tsa tlhahlobo ea boleng ho MFDC welding ke tlhahlobo ea seam ea weld. Sena se kenyelletsa ho lekola geometry, boholo, le ponahalo e akaretsang ea weld. Seam se cheselitsoeng hantle se lokela ho ba sebopeho se ts'oanang, se se na likoli tse bonoang joalo ka mapetsong kapa porosity, 'me se be le profil e ts'oanang ea lifaha. Lits'oants'o life kapa life tsa seam weld li ka lebisa mefokolong ea sebopeho le ho fokotsa ts'ebetso ea sehlahisoa.
2. Teko ea Matla a Weld:
Ho netefatsa bots'epehi ba mochini oa weld, tlhahlobo ea matla e bohlokoa. Mekhoa e fapaneng e ka sebelisoa, joalo ka tlhahlobo ea matla kapa tlhahlobo ea ho inama, ho lekola bokhoni ba weld ba ho mamella khatello ea maikutlo. Liphetho tsa liteko tsena li lokela ho kopana kapa ho feta litekanyetso tse boletsoeng, joalo ka ha ho laetsoe ke projeke kapa litlhoko tsa indasteri.
3. Tlhahlobo ea Liparamente tsa Motlakase:
MFDC spot welding e itšetlehile ka taolo e nepahetseng ea liparamente tsa motlakase, ho kenyeletsoa hona joale, voltage, le nako. Ho beha leihlo le ho sekaseka liparamente tsena ho bohlokoa bakeng sa taolo ea boleng. Ho kheloha ho tsoa ho boleng bo boletsoeng ho ka baka boleng bo sa tsitsang ba weld. Ka hona, tlhahlobo e tsoelang pele le tlhahlobo ke ea bohlokoa ho netefatsa hore mochini oa welding o sebetsa ka nepo.
4. Electrode Wear le Tlhokomelo:
Boemo ba li-electrode tsa welding bo bohlokoa bakeng sa boleng ba li-welds tsa letheba. Ho hlahlojoa khafetsa ha li-electrode bakeng sa ho senyeha hoa hlokahala. Li-electrode tse senyehileng li ka lebisa ho se kopane ho fokolang, ho fella ka li-welds tse sa tsitsang. Tlhokomelo e nepahetseng le ho nchafatsa li-electrode ha ho hlokahala ke tsa bohlokoa bakeng sa ho boloka boleng.
5. Tikoloho ea Welding le Polokeho:
Tlhahlobo ea boleng e boetse e lokela ho nahanela tikoloho ea li-welding le mekhoa ea polokeho. Sebaka sa ho sebetsa se hloekileng le se nang le moea o motle se bohlokoa bakeng sa ho netefatsa boleng ba li-welds. Ho feta moo, ho latela melaoana ea ts'ireletso ho bohlokoa ho sireletsa basebetsi le ho netefatsa bots'epehi ba ts'ebetso ea welding.
6. Litokomane le ho Boloka Rekoto:
Ho boloka lirekoto tse felletseng tsa ts'ebetso ea welding ho bohlokoa bakeng sa taolo ea boleng le ho lateloa. Lirekoto tsena li lokela ho kenyelletsa lintlha tse joalo ka li-parameter tsa welding, tlhaiso-leseling ea opareitara, liphetho tsa tlhahlobo, le mehato efe kapa efe ea tokiso e entsoeng.
Qetellong, tlhahlobo ea boleng ka har'a tjheseletsa ea mabala a mahareng a maqhubu a mahareng ke ts'ebetso e nang le likarolo tse ngata. Ho netefatsa boleng ba li-welds ho kenyelletsa tlhahlobo ea li-weld seams, tlhahlobo ea matla, ho lekola likarolo tsa motlakase, tlhokomelo ea li-electrode, ho boloka tikoloho e bolokehileng ea weld, le litokomane tse hlokolosi. Mehato ena ka kopanelo e kenya letsoho tlhahisong ea li-welds tsa boleng bo holimo tse fihlelang litekanyetso tsa indasteri le litebello tsa bareki.
