Tlhaloso: Ena ke sodium e tlase ea hydrogen e koahetsoeng ka electrode e khethehileng bakeng sa tšepe ea aluminiized.Sebelisa DCEP (electrode e nepahetseng hona joale), 'me e ka chesetsoa maemong ohle ka ts'ebetso e khuts'oane ea arc.J557SLA e ka ts'oaroa ka kotloloho ntle le ho tlosa lesela le nang le aluminized holim'a groove pele ho welding.Empa J557SLB e lokela ho tlosa lera la aluminiized holim'a groove pele ho tjheseletsa.

Tšebeliso: E sebelisetsoa ho cheseletsa mohaho oa tšepe o entsoeng ka aluminiized tlas'a corrosion medium ea hydrogen sulfide, sulfur, ammonia, ammonium bicarbonate le hydrogen nitrogen e nang le mocheso o sebetsang o ka tlase ho 540 ° C.Joalo ka liphaephe tsa boiler, lisebelisoa tsa ho hloekisa peterole, lisebelisoa tsa manyolo le liphaephe tsa mouoane, jj.

 Sebopeho sa lik'hemik'hale tsa tšepe ea weld(%):

 Mechine ea tšepe ea weld:

Likahare tsa hydrogen tsa tšepe e kentsoeng: ≤6.0mL/100g (mokhoa oa glycerin)

Tlhahlobo ea X-ray: Ke ea sehlopheng

Nako e khothalelitsoeng:

Tlhokomeliso:

1. Electrode e tlameha ho behoa bakeng sa hora e le 1 ho pota 350 ℃ pele ho ts'ebetso ea welding;

2. Ho bohlokoa ho hloekisa mafome, sekala sa oli, metsi le litšila holim'a likarolo tsa ho tjheseletsa pele ho tjheseletsa.
