Maemo a tjheseletsa le litlhaloso ke lintlha tsa bohlokoa ho fihlella li-welds tse tšepahalang le tsa boleng bo holimo ka har'a mochini oa welding oa maqhubu a mahareng. Sengoliloeng sena se fana ka kakaretso ea maemo a tjheseletsa le lintlha tse lokelang ho nahanoa bakeng sa ts'ebetso e atlehileng ea li-welding.
- Maemo a Welding: Maemo a nepahetseng a ho tjheselletsa tjheseletsa a netefatsa motswako o lakatsehang, matla le botshepehi ba ditjheseletso tsa matheba. Lintlha tsa bohlokoa tsa maemo a welding li kenyelletsa:
- Litlhophiso tsa hajoale le tsa motlakase: Ho khetha boleng bo nepahetseng ho latela mofuta oa thepa, botenya le litlhoko tse kopaneng.
- Nako ea ho tjheseletsa: Ho beha nako ea ho phalla ha hona joale ho finyella mocheso o lekaneng le ho kenella ka nepo.
- Electrode force: Ho sebelisa khatello e nepahetseng ho netefatsa ho kopana hantle le deformation e nepahetseng ntle le ho baka tšenyo.
- Nako ea ho pholisa: Ho lumella nako e lekaneng hore weld e phole le ho tiea pele e tlosa khatello.
- Litlhaloso tsa Welding: Litlhaloso tsa welding li fana ka litataiso le litekanyetso tsa ho fihlela li-welds tse tsitsitseng le tse tšepahalang. Lintlha tsa bohlokoa mabapi le litekanyetso tsa welding li kenyelletsa:
- Tšebelisano ea lintho tse bonahalang: Ho netefatsa hore lisebelisoa tsa motheo le lisebelisoa tsa elektrode li loketse ts'ebeliso e reriloeng.
- Moralo o kopaneng: Ho latela litlhophiso tse kopaneng tse boletsoeng, ho kenyeletsoa bolelele ba ho fetana, sebaka sa lekhalo, le ho itokisa.
- Saese ea weld le sebaka: Ho latela boholo bo boletsoeng ba weld nugget, sekontiri se phahameng le litlhoko tsa sebaka.
- Mekhoa ea ho amohela: Ho hlalosa litekanyetso tsa boleng ba ho lekola li-welds, joalo ka boholo bo amohelehang ba nugget, mefokolo e bonahalang, le litlhoko tsa matla.
- Mokhoa oa ho cheselletsa tjheseletsa: Mokhoa o hlalositsoeng hantle oa welding o bohlokoa bakeng sa ho boloka botsitso le boleng ba ho cheselletsa matheba. Ts'ebetso ea welding e lokela ho kenyelletsa:
- Litokisetso tsa pele ho weld: Ho hloekisa holim'a metsi, ho beoa ha thepa, le ho tsamaisana le li-electrode.
- Tatellano ea ts'ebetso: Mehato e hlalositsoeng ka ho hlaka bakeng sa ho beha li-electrode, ts'ebeliso ea hajoale, ho pholisa le ho tlosoa ha li-electrode.
- Mehato ea taolo ea boleng: Mekhoa ea tlhahlobo, tlhahlobo e sa senyeheng, le litokomane tsa liparamente tsa welding.
- Ho lumellana le Maemo le Melawana: Mechini ea welding ea maqhubu a mahareng e lokela ho latela litekanyetso le melaoana ea polokeho. Tsena li ka kenyelletsa:
- Maemo a machaba: ISO 18278 bakeng sa tjheseletso sebakeng sa koloi, AWS D8.9 bakeng sa tjheseletso sebakeng sa sefofane, jj.
- Melao ea polokeho ea lehae: Ho lumellana le polokeho ea motlakase, ho lebela mochini, le litlhoko tsa tikoloho.
Ho ikamahanya le maemo a loketseng a ho cheselletsa le lintlha ke tsa bohlokoa bakeng sa ho fihlela li-welds tse tsitsitseng, tse tšepahalang le tsa boleng bo holimo ka mochini oa tjheseletsa oa maqhubu a mahareng a maqhubu. Ka ho hlahloba ka hloko lintlha tse kang oa welding current, nako, matla a electrode le ho pholisa, basebetsi ba ka etsa bonnete ba ho kopanya hantle, matla a manonyeletso le botšepehi ba mahlakore. Ho latela lintlha le lits'ebetso tsa welding, le ho ipapisa le litekanyetso le melaoana e sebetsang, ho netefatsa boleng bo lakatsehang le ho ts'ehetsa katleho e akaretsang ea ts'ebetso ea ho cheselletsa matheba.
