Litlhokomelo tsa Welding:
Pele ho tjheseletsa, weldment e tlameha ho se be le oli ka ho feletseng, mafome, mongobo, joalo-joalo; ho omisa ka 350 ° C ka hora; le ho omisa ka tshebediso
3. Sebelisa welding pase e moqotetsane le welding e khuts'oane ea arc; Khokahano ea AC le DC e khutlisetsa morao.

E ka sebelisoa bakeng sa ho tjheseletsa tšepe e tlase ea khabone le 490MPa e matla e phahameng ea tšepe ea tšepe e kopantsoeng, e ka hlokomela sebopeho se nang le mahlakore a mabeli.

Electrode ke ea mofuta o tlase oa hydrogen, phala ea welding le sebopeho se akaretsang sa motso oa weld, se khona ho hlokomela sebopeho se nang le mahlakoreng a mabeli, kahoo se ka boloka serethe sa ho hloekisa, e le hore ts'ebetso ea welding e ka ntlafatsoa. .

Lintlha tsa bohlokoa tsa ts'ebetso:

1, ho omisa pele o sebelisoa, 300 ~ 350 ℃ ho omisa metsotso e 30 ~ 60;

2, khetha e loketseng hona joale le groove, e le hore ho fumana e ntle morao weld;

3. Ha o tima arc, tsamaisa sekoti sa arc ka lehlakoreng la groove ebe o senya arc;

4. Arc nako ea ho qala ho sebelisa arc ho qala poleiti kapa ka lehlakoreng la groove arc;

5. Boloka li-welding tse khutšoane tsa arc;

6. Sebelisa AC kapa DC reverse connection.
