Weld pipe weld porosity ha e ame feela ho teteana ha liphaephe, ho etsa hore phaephe e lutle le ho bola e tla susumetsoa ke ntlha e fokotsang matla le ho tiea ha tjheseletsa.Lintlha tsa weld porosity ke: phallo ea metsi, litšila, oxide le lithapo tsa tšepe, lisebelisoa tsa welding le botenya ba sekoaelo, tšepe ea boleng bo holimo le lipoleiti tsa mahlakoreng a tšepe, theknoloji ea welding le lits'ebetso tsa ho bopa tšepe.

Mehato e amanang le thibelo:

1. Lisebelisoa tsa Flux.CaF2 le SiO2 e nang le palo e loketseng ea tjheseletsa, karabelo e tla monya palo e kholo ea H2, e hlahise botsitso bo phahameng ba HF e ke keng ea qhibiliha ka tšepe ea mokelikeli, kahoo e thibela ho thehoa ha masoba a khase ea hydrogen.

2. Botenya ba bongata ba flux ka kakaretso ke 25-45mm, boholo ba karoloana e kholo ea solder, hora ea boima ba bongata e nka botenya bo boholo, athe boleng bo tlase;phahameng hona joale, tlaase tjheseletsa lebelo bokella nka botenya palo e kahodimodimo, athe bonyane ba boleng tlatsetso, lehlabula kapa mongobo moea, phallo fola lokela ho omisoa pele ho sebelisoa.

3. Letlapa la tšepe le entsoeng ka holim'a metsi.Ho qoba buka e bulehileng ho theola oxide scale le lithōle tse ling ha li etsoa, ​​​​boto e lokela ho beoa sesebelisoa sa ho hloekisa.

4. Ts'ebetso ea bohale ba tšepe ea tšepe.Tšepe poleiti bohale lokela ho beha mafome le burr ho tloswa sesebediswa ho fokotsa ho khoneha moloko oa masoba.Ho tlosa sesebediswa hlomamisa ka boemo bo molemo ka ho fetisisa ka mor'a hore mochini siloa le disc sekala, sebopeho sa sesebediswa ke e sebetsang terata lebili lehlakoreng la bobeli holimo le tlaase boemo lekhalo fetolehang, e ka holimo le tlaase clamping poleiti bohale.

5. Weld profile.Weld forming factor e nyane haholo, e moqotetsane ebile e tebile sebopeho sa weld, khase le ho kenyeletsoa ha ho bonolo ho tsoa, ​​ho bonolo ho etsa li-pores le slag.Kakaretso weld coefficient taolo ka 1.3-1.5, phala e teteaneng e nang le marako a mangata, boleng ba bonyane ba marako a tšesaane.

6. Fokotsa matla a bobeli a khoheli.Ho fokotsa tšusumetso ea matla a khoheli e lokela ho etsoa ka workpiece tjheseletsa kabel kgokelo sebaka feela khoneha hole le tjheseletsa terminal, ho qoba ba bang ba tjheseletsa kabel bobeli matla a khoheli generated ka workpiece.

7. Mosebetsi oa matsoho.E lokela ho ba ho loketseng ho fokotsa kapa ho eketsa lebelo la tjheseletsa hona joale, ka tsela eo ho lieha crystallization sekhahla bath tšepe tjheseletsa e le hore ho bebofatsa phonyoha khase, ka nako e tšoanang, haeba hlobolisa pelehi sebaka ho hloka botsitso, e lokela ho ka nako e loketseng fetotsoeng ho. Tlosa ho lokisa khafetsa ka mor'a ho amoheloa ha axle e ka pele kapa borokho ho boloka ho bōptjoa, ho etsa hore khase e balehe ka thata.
