Pasi pemamiriro echando, yakaderera-kabhoni simbi welding, kutonhora kweyero yejoini yakasungwa, iyo yakaita kuti kutsemuka kuwedzere, kunyanya mukutanga weld Zvimiro zvinorema zvinogona kuputika, zvinofanirwa kutora matanho anotevera:

1) Izvo hazvigoneke pasi pemamiriro ekudzika kwekushisa kukotama, kururamisa uye gungano weldments.

2) Preheat, 16Mn isina musono simbi pombi welding process yakanyatso chengetedzwa interlayer tembiricha haifanirwe kudonha pasi peiyo preheating tembiricha.

3) Hydrogen kana ultra-low hydrogen welding.

4) Iyo yese seam inoenderera welding inofanira kupedzwa kuti isakanganiswa.

5) Pakuisa welding kuti uwedzere welding ikozvino, welding yekumhanyisa inononoka, nekuda kwekuwedzera tack welds mhiri-sectional nzvimbo uye kureba, preheated kana zvichidikanwa.

6) Kwete kuitwa pane base zvinhu arc groove pamusoro kunze kwekudiwa kwekuzadza crater kana yatsakatika.
