Cr18Ni9Ti tšepe e sa hloekangФ159 limilimithara×Manonyeletso a 12mm a phala e kgolo a tshekaletseng a tshekaletseng a dibono a sebediswa haholo disebedisweng tsa matla a nyutlelie le disebediswa tse itseng tsa dikhemikhale tse hlokang mocheso le ho hanyetsa asiti.Ho tjheseletsa ho thata mme ho hloka manonyeletso a phahameng a tjheseletsa.Bokaholimo bo hlokeha hore bo bōpehile, bo be le li-protrusions tse itekanetseng, 'me ho se na likheo.Litlhahlobo tsa PT le RT lia hlokahala kamora ho tjheseletsa.Nakong e fetileng, ho ne ho sebelisoa welding ea TIG kapa manual arc welding.Ea pele e na le ts'ebetso e tlase le litšenyehelo tse phahameng, athe ea morao-rao e thata ho tiisa 'me e na le katleho e tlaase.E le ho netefatsa le ho eketsa lebelo, lera le ka tlaase le cheselitsoe ke mokhoa oa ho tlatsa terata ea ka hare ea TIG le ka ntle, 'me MAG welding e sebelisetsoa ho tlatsa le ho koahela bokaholimo e le hore katleho e tiisetsoe.2. Sekhahla sa katoloso ea mocheso le conductivity ea motlakase ea 1Cr18Ni9Ti tšepe e sa jeleng paate e fapane haholo le ea tšepe ea carbon le alloy e tlase, 'me letamo le qhibilihisitsoeng le na le metsi a fokolang le sebopeho se fosahetseng, haholo-holo ha ho chesetsoa maemong ohle.Nakong e fetileng, MAG (Ar+1%～2% O2) tšepe e sa jeleng tšepe e ne e sebelisoa feela bakeng sa tjheseletsa e bataletseng le tjheseletsa e sephara.Ts'ebetsong ea welding ea MAG, bolelele ba terata ea welding bo ka tlase ho 10mm, bophahamo ba maqhubu, maqhubu, lebelo, le nako ea ho lula ea sethunya se hokahanngoa hantle, 'me ketso e hokahantsoe.Fetola angle ea sethunya sa tjheseletsa ka nako efe kapa efe, e le hore moeli oa seam oa welding o kopane ka makhethe le ka bokhabane ho etsa bonnete ba ho tlatsa Le ho koahela lera.

2. Mokhoa oa ho tjheseletsa: Thepa ke 1Cr18Ni9Ti, boholo ba pipe keФ159 limilimithara×12mm, setsi se entsoe ka tjheseletsa ea argon arc, khase e tsoakiloeng (CO2 + Ar) e sirelelitsoeng e sirelelitsoeng le welding ea sekoaelo, welding e otlolohileng le e otlolohileng e tsitsitseng maemong ohle.

3. Ho itokisa pele ho tjheseletsa: 1. Hloekisa oli le litšila, 'me u sila bokaholimo ba groove le 10mm e potolohileng ho fumana tšepe e khanyang.2.
