Indastering ea kajeno ea tlhahiso, ts'ebeliso ea mechini ea tjheseletsa ea sebaka se mahareng (DC) e atile ka lebaka la ts'ebetso ea bona le ho nepahala ha ho theha li-welds tse matla le tse tšepahalang. Leha ho le joalo, ho netefatsa boleng ba lintlha tsa weld ho bohlokoa haholo ho netefatsa boleng ba sebopeho le ts'ebetso ea sehlahisoa sa ho qetela. Sengoliloeng sena se fana ka mokhoa o felletseng le ts'ebetso ea ho lekola lintlha tsa weld mochining oa li-welding oa DC oa maqhubu a mahareng.
Mechini ea welding ea DC ea maqhubu a mahareng e sebelisoa haholo liindastering tse fapaneng bakeng sa bokhoni ba eona ba ho hlahisa li-welds tsa boleng bo holimo. Mechini ena e theha maqhama a matla le a tšoarellang lipakeng tsa likarolo tsa tšepe, e leng se etsang hore e be tsa bohlokoa haholo indastering ea likoloi, sefofane le lisebelisoa tsa elektroniki. Ho boloka boleng ba weld, ho bohlokoa ho theha mokhoa o tšepahalang oa tlhahlobo le ts'ebetso. Sengoliloeng sena se bua ka mokhoa o sebetsang le o sebetsang oa ho fihlela sepheo sena.
Mokhoa oa ho hlahloba ntlha oa weld o hlalositsoeng mona o kopanya theknoloji e tsoetseng pele le ts'ebetso e hlophisitsoeng ho netefatsa liphetho tse nepahetseng. Mehato e latelang e ameha:
1. Boitokisetso:
- Qala ka ho theha mochini o tjheseletsang letheba la DC le lisebelisoa tsa ho tjheseletsa.
- Netefatsa hore li-parameter tsa welding, joalo ka tsa hajoale, voltage, le khatello, li lekantsoe ho ea ka boleng bo lakatsehang.
2. Mokhoa oa ho cheselletsa:
- Etsa ts'ebetso ea welding ea letheba ho ea ka mekhahlelo e behiloeng. Mohato ona o tiisa hore lintlha tsa weld li bōptjoa ho ea ka litekanyetso tse lakatsehang.
3. Tlhahlobo:
- Sebelisa mekhoa ea tlhahlobo e sa senyeheng, joalo ka tlhahlobo ea ultrasonic kapa tlhahlobo ea X-ray, ho lekola bonnete ba lintlha tsa weld. Mohato ona ke oa bohlokoa bakeng sa ho khetholla mefokolo kapa liphoso tse ka bang teng.
4. Tlhahlobo:
- Sekaseka liphetho tsa tlhahlobo ho fumana boleng ba lintlha tsa weld. Haeba ho na le liphoso tse fumanoeng, nka mehato ea ho li lokisa.
5. Litokomane:
- Boloka lirekoto tse felletseng tsa ts'ebetso ea tlhahlobo, ho kenyeletsoa liparamente tse sebelisitsoeng, liphetho tsa tlhahlobo, le mehato efe kapa efe ea tokiso e entsoeng.
Qetellong, ho netefatsa boleng ba lintlha tsa weld ka har'a mechini ea welding ea DC spot welding ke ea bohlokoa bakeng sa ho hlahisa lihlahisoa tse sebetsang hantle le tse tšepahalang. Sengoliloeng sena se fane ka mokhoa le ts'ebetso ea ho hlahloba lintlha tsa weld, ho kopanya ho itokisa, ho cheselletsa, ho hlahloba, ho hlahloba le mekhahlelo ea litokomane. Ka ho latela tataiso ena, bahlahisi ba ka ntlafatsa boleng ba lihlahisoa tsa bona le ho boloka botšepehi ba li-welds tsa bona, e leng se lebisang ho lihlahisoa tse sireletsehileng le tse sebetsang hantle.
