Ho chesoa ha li-flange tse kholo ke karolo e kopanyang liphaephe ho e mong, e kopantsoeng le pheletsong ea liphaephe, 'me e tiisitsoe ka gasket pakeng tsa bona.Ho chesoa ha li-flange tse kholo, tse tsejoang hape e le li-welding flanges, ho na le masoba holim'a li-flange tse cheselletsang
Khokahano e thata ke mofuta oa motsoako o nang le sebopeho sa disc o atisang ho fumanoa boenjiniere ba liphaephe.
Ho hlokahala lebelo le phahameng la ho forging (150-200mm/s) bakeng sa ho cheselletsa tšepe ka conductivity e ntle ea mocheso oa li-flange tse kholo.Mabapi le tšepe e tšoanang, ho na le mocheso o moholo oa mocheso sebakeng sa li-interface ka lebaka la tlhaho e batang ea motsoako

Ha ho cheselletsa li-flange tse kholo, haeba khatello e ka holimo ea forging e le nyane haholo, deformation ha e lekane 'me matla a manonyeletso a fokotseha;Haeba khatello e phahameng ea ho qhekella e le matla haholo, deformation e tla ba e kholo haholo, 'me lijo-thollo tsa kristale li tla sotheha li be li be matla, e leng se tla fokotsa ho tiea ha lenonyeletso.
Lebelo la leseli le khanyang le tla etsa hore ho be le keketseho ea mocheso oa mocheso, kahoo ha tšepe ea tjheseletsa e nang le conductivity e ntle ea mocheso (koporo, li-alloys tsa aluminium), li-flange tse khethehileng tsa tšepe li hloka khatello e kholo ea ho qapa (150-400Mpa).
Ho phaella ho mekhahlelo e ka holimo ea ts'ebetso, mocheso oa preheating le preheating nako e boetse e lokela ho nkoa bakeng sa litekanyetso tsa preheating tse khanyang tsa welding.Mocheso oa preheating o khethiloe ho latela karolo ea mosebetsi oa sefapano le mosebetsi oa thepa.Ha u tjheseletsa tšepe e nang le carbon e tlase,

Ka kakaretso, li-arc welding li sebelisoa bakeng sa ho cheselletsa li-flange tse kholo, tse nang le mela e sa tloaelehang ea li-arc le ho chesa habonolo le ho fokotsa moeli oa lesela, o ke keng oa felisoa esita le ka machining, ho fella ka boleng bo bobe ba ponahalo;2.
