Laser welded carbon steel finned tube ke eng?

Laser welded carbon steel finned tube e amohela ts'ebetso ea welding ea laser, e ka cheselletsang li-tubes tsa carbon steel le mapheoana a tšepe a carbon a nang le botenya bo botenya ba lebota le sekontiri se teteaneng sa mapheo.Li-tubes tse tšesaane tse se nang letho le mapheo a teteaneng li ka ntlafatsa ts'ebetso ea phetiso ea mocheso.

Hobaneng u sebelisa laser welded carbon steel finned tube?

Qalong, mochini o nang le laser welded finnings haholo-holo o ne o tjheselletsa tube ea tšepe e sa hloekang e nang le mapheoana a tšepe.Nakong ea ts'ebetso ea theknoloji e ntseng e tsoela pele, tube ea carbon steel e nang le carbon steel fin e fetoha encomical, joalo ka boima bo tlase le matla a ho fetisa mocheso.Ka linako tse ling, Laser welded carbon steel finned tube e ka nkela sebaka sa maqhubu a phahameng a tjheselitsoeng ka thata.

Mochini oa welding oa laser o ikatisang oa spiral fin o sebelisa laser e matla haholo ho tjheseletsa li-tubes tse feliloeng.Mocheso oa laser o fokotsehile, phello e nepahetse, 'me lepheo ka mor'a ho tjheseletsa ha le na phello e fokolang mochesong oa laser.Thepa eohle e entsoe ka botlalo, e nang le mapheoana a nang le mapheo ka lehlakoreng le leng le mapheoana a cheselitsoeng ka laser ka lehlakoreng le leng.Nakong ea ts'ebetso eohle ea tlhahiso, opareitara e hloka feela ho kenya thepa qalong ea welding le ho e laolla ka mor'a hore welding e phethoe.Ts'ebetsong e tloaelehileng, mohala oa tšepe o lematsoa ka bohona phala ea tšepe, 'me ho phethoa ha lakane ka othomathike, welding ea othomathike ea laser, le tekanyo e phahameng ea boits'oaro e fihlelleha.

Li-tubes tsa Spiral finned esale li hlahisoa ke welding e phahameng ea maqhubu, brazing kapa inlaying.Ts'ebetso ena ea setso ea tlhahiso e etsa hore phetisetso ea mocheso le katleho ea pholileng ea tube e feliloeng e se phahame haholo, 'me ho tla ba le welding e fokolang le de-soldering.Habohlokoa le ho feta, ka mor'a hore ho cheselle maqhubu a mangata, mocheso o phahame haholo 'me phello ea mocheso e kholo haholo, e leng se etsang hore habonolo tube e entsoeng ka mafome e be mafome, e leng ho fokotsang tikoloho ea tšebeliso ea tube e finned.Sebakeng se senyang, tube e nang le maqeba e tla senyeha ka mor'a nako e khutšoanyane ea tšebeliso.Esita le haeba tube e entsoeng ka tšepe e sa hloekang e cheselitsoe ka makhetlo a mangata, e ke ke ea finyella litlhoko, haholo hobane mapheo a monya mocheso o mongata haholo 'me mocheso o phahame haholo, e leng se amang tokisetso ea athomo ea tšepe e sa hloekang.Tšepe e sa hloekang e halefileng, e bonolo ho rusa le ho fokotsa ho hanyetsa ha kutu.Laser welding ha e hloke ho nahana ka litaba tse joalo ho hang.Laser welding e etsoa hang hang, 'me mapheo a cheselitsoeng ha a na phello ea ho hlaphoheloa ha mocheso.Khanyetso ea kutu ea tšepe e sa hloekang ha e fokotsehe, ka hona, libakeng tse matla tsa asiti le alkali, li-tubes tsa laser welding finned li lokela ho ba le bokhoni.

Melemo ea laser welded carbon steel helical fin tubes

1.Laser welded carbon steel finned tubee amohela mochini o tsoelang pele oa welding oa laser ho phethela ho tjheseletsa ha sesebelisoa sa matsoele sa finned tube automatic.Mapheoana a cheselitsoe ka thata haholo.Mapheoana le liphaephe li cheselitsoe ntle le hore li sieo.

2. Laser welding ea carbon steel finned tubes ke ho qhala motheo oa tšepe ea mapheoana le li-tubes ho hlokomela welding.Matla a tube e feliloeng e ka fihla ho feta 600MPa.

3. Laser welding carbon steel finned tube e sebelisang mochini oa welding oa othomathike oa laser o amohela mochini oa servo o koetsoeng, o nang le phetisetso e nepahetseng haholo le welding e nepahetseng.

4. The fin spacing ea laser welded carbon steel finned tube e ka ba ≤2.5mm, sebaka sa ho qhala mocheso se eketsehile ka hoo e ka bang 50% ha se bapisoa le tube e nang le maqhubu a phahameng (the fin spacing ≥4.5mm), le lisebelisoa ka unit. sebaka ba ka tlaase ho moo, e leng ka haholo fokotsa phetolo Heater bophahamo ba modumo.
