Lintlha tsaweldmefokolo

(1) Lintlha tse bonahalang:

Ntho eo ho thoeng ke ea lintho tse bonahalang e bua ka litšepe tsa welding le lisebelisoa tsa welding tse sebelisoang, joalo ka lithapo, melamu, flux, le khase e sireletsang joalo-joalo.Lisebelisoa tsena kaofela li ameha ka kotloloho ho tjheseletsa puddle kapa physico-chemical reaction of the fusion zone, moo thepa ea motheo ea ts'ebetso e ntle ea thepa ka boeona, moriti oa mocheso oa libaka tse peli o hlasela phello ea makhaola-khang.Ka sebopeho le thepa ea tšepe weld e boetse ke ntlha ea bohlokoa ka ho tjheseletsa thepa e sebelisoa ka ho hlaka.Litholoana tse ntle le lisebelisoa tsa tšepe tsa motheo ha li lumellane, ha li ka baka liphoso tse fapaneng sebakeng sa weld ho ea ho mela, li-pores, joalo-joalo, 'me li ka fumaneha ho tloha ho embrittlement, thepa e hananang le kutu ho nolofatsa kapa ho fetoha.Ka hona, e le hore ho etsa bonnete ba e ntle tjheseletsa manonyeletso lokela ho ela hloko ka ho feletseng lintho tse bonahalang.

(2) Lintlha tsa theknoloji:

Mekhoa e mengata e pakile hore mofuta o tšoanang oa tšepe ea motheo ka mekhoa e fapaneng ea ho tjheseletsa le maemo a mehato ea ts'ebetso, boleng ba welding bo tla bontša phapang e kholo.Ama boleng ba mokhoa oa ho tjheseletsa oa ho tjheseletsa ka sehloohong ho khoneha ka likarolo tse peli: Ea pele, litšoaneleho tsa mohloli oa mocheso oa welding, e leng matla a matla, mocheso o phahameng oa ho futhumatsa, matla a matla, joalo-joalo, a ka fetola liparamente tsa welding. mocheso potoloho ka ho toba, tse kang mola oa matla, phahameng-mocheso bodulo nako, lekhato la phetoho mocheso mefuta e fapaneng ya lebelo tsidifatso.Tsena ehlile li tla ama microstructure le thepa ea manonyeletso;ea bobeli ho letamo le sebakeng se haufi sa tšireletso, joalo ka tšireletso ea slag, khase, khase - tšireletso e kopanetsoeng ea slag kapa welding ka vacuum, e tla ama ts'ebetso ea ho cheselletsa metallurgy.Ho hlakile hore, tshebetso tjheseletsa dithulaganyo mogote le metallurgical bakeng sa boleng le tshebetso tla ke keng ea qojoa manonyello phello ea makhaola-khang.
