Ea bobeli: ts'ebetso ea welding

Khetho ea lisebelisoa tsa tšepe tse sa hloekang li lokela ho latela molao-motheo oa "homogeneity".

1. Ferritic tšepe e sa hloekang Haeba ts'ebetso ea welding e futhumala ka 430-480 ° C ka nako e telele 'me e pholile butle-butle, ho bonolo haholo ho hlahisa 475 °C brittleness,' me litšila li tla phetha karolo ea bohlokoa. Ts'ebetso ea ho tjheseletsa e khothaletsa ho tjheseletsa hona joale ho tlase, ho potlaka, ho se na oscillation, le taolo e tlase ea mocheso oa interlayer nakong ea li-welding tse ngata. Ho weld workpieces e teteaneng, seam weld se tlameha ho hatelloa ho fokotsa khatello ea maikutlo.

2. Martensitic tšepe e sa hloekang mocheso-a ameha libaka embrittlement le tjheseletsa mapetsong batang ho hlokahala ho qoba ka hohle kamoo ho ka khonehang ha tjheseletsa, ka kakaretso nka preheating e tsamaellanang pele tjheseletsa (150-300 °C) le ka mor'a tjheseletsa mocheso kalafo (700-750 ° C) mehato, ts'ebeliso ea matla a maholo a mohala, haeba ho hlokahala, o ka khetha lisebelisoa tsa welding tsa austenitic.

3. Austenitic stainless steel Lintlha tse susumetsang tsa ho phatloha ho chesang le ho bola ha intergranular ke lintlha tse ka sehloohong tsa ho cheselletsa tšepe e joalo e sa hloekang, ka lebaka la litšobotsi tsa eona tsa 'mele, ho lokela ho nkoa matla a manyenyane bakeng sa ho cheselletsa, ho pholisa ka potlako le mocheso o tlase oa interlayer. lokela ho laoloa ha multilayer tjheseletsa. Loanela ho ba le ferrite e lekaneng ha u cheselletsa ho thibela ho hlaha ha mapetsong a mocheso. Indasteri ea petrochemical e kang hydrogenation reactors le lihlahisoa tse ling tse khethehileng, palo ea ferrite (FN) ea weld e hlalositsoe ka ho hlaka, ka kakaretso e hlokahala 3-10.

4. Austria-iron duplex stainless steel e na le tšekamelo e tlase ea ho peperana ha e bapisoa le tšepe ea austenitic; Ha ho bapisoa le tšepe ea ferritic, post-weld embrittlement e tlase, kahoo e na le weldability e babatsehang, ha e chese pele kapa ka mor'a ho futhumatsa, 'me ha ho na mapetsong a tjheseletsa a hlahisoang. Leha ho le joalo, ha ho futhumatsa mocheso o phahameng, ho na le tšekamelo ea hore lijo-thollo li hōle, 'me matla a manyenyane a mela e lokela ho nkoa ha ho chesetsoa.

5. Mokelikeli o thata oa tšepe e sa hloekang Ka lebaka la boima bo phahameng, boima bo bobe le polasetiki ea mofuta ona oa tšepe, le khatello e kholo ea masala a welding, ho bonolo ho hlahisa mapetsong. Ho khothalletsoa ts'ebetso ea welding e ts'oanang le tšepe e sa hloekang ea martensitic, empa mocheso oa preheating o hloka ho eketseha.
