Tlhokomeliso:
- Electrode e tlameha ho behoa hora e le 'ngoe ka mocheso oa 300 ℃ pele o sebetsa.Leka ho sebelisa arc e khuts'oane ho cheselletsa;
- Ho bohlokoa ho hloekisa mafome, oli, metsi le litšila holim'a likarolo tsa tjheseletsa pele ho tjheseletsa.
3. Leka ho sebelisa matla a mohala o monyane ha ho tjheseletsa, ho etsa li-multi-layer le multi-pass welding.
