E le ho thibela ho hlaha ha mapheo a laminar, ntho ea bohlokoa ka ho fetisisa moralong le ts'ebetsong ea kaho ke ho qoba khatello ea maikutlo ea Z-direction le khatello ea maikutlo, mehato e tobileng ke e latelang:
1. Ntlafatsa moralo o kopanetsoeng ho fokotsa khatello e thibetsoeng. Mehato e khethehileng e kang: e tla etella pele ho atolosa poleiti ea arc ea bolelele bo itseng, ho ba le phello ea ho thibela ho phunyeha; fetola tlhophiso ea weld ho fetola tataiso ea khatello ea khatello ea khatello ea maikutlo, poleiti e otlolohileng ea arc ho poleiti e otlolohileng ea arc, fetola boemo ba weld, e le hore kopanelo ea tataiso eohle ea matla a bapang le lera le phuthoang, e ka ntlafatsa haholo. tshebetso ya ho taboha ha anti-laminar.
2. Amohela mokhoa o nepahetseng oa ho tjheseletsa, tšebeliso ea mokhoa o tlaase oa hydrogen welding e ntle, joalo ka tjheseletsa e sirelelitsoeng ka khase, tšekamelo e ka tlas'a metsi ea arc welding batang ke e nyane, e thusa ho ntlafatsa ts'ebetso ea anti-laminar ho rusolla.
3. Tšebeliso ea matla a tlaase a bapisoang le lisebelisoa tsa welding, tšepe ea weld e na le ntlha e tlaase ea lihlahisoa, ductility e phahameng, e bonolo ho etsa hore khatello e be teng ka har'a weld le ho fokotsa sebaka se amehileng ke mocheso oa thepa ea motheo, e ka ntlafatsa ts'ebetso. ea ho taboha ha anti-laminar.

5. E le ho thibela ho rusolla ha laminar ho bakoang ke ho phunyeha ha serame, re lokela ho leka ka hohle ho nka mehato e meng ea ho thibela ho phatloha ho batang, joalo ka ho ntlafatsa preheating le ho laola mocheso oa interlayer, joalo-joalo Ho phaella moo, re ka boela ra sebelisa mekhoa ea ho imolla khatello ea kelello. joalo ka annealing e mahareng.
6. Re ka boela ra laola boholo ba weld, re sebelisa maoto a manyenyane a ho tjheseletsa, mokhoa oa ho tjheseletsa oa mechine e mengata.
