Ngaphantsi kweemeko ezibandayo i-low-carbon steel welding, izinga lokupholisa le-welding edibeneyo, eye yenza ukuthambekela kokuqhekeka kwanda, ngakumbi kwi-weld yokuqala Izakhiwo ezinzima ziyakwazi ukuqhekeka, kuyimfuneko ukuthatha amanyathelo alandelayo enkqubo:

1) Akunakwenzeka phantsi kweemeko zokugoba kweqondo eliphantsi, ukulungiswa kunye ne-weldments yendibano.

2) Ukushisa, i-16Mn yensimbi engenamthungo inkqubo yokuwelda igcinwe ngokungqongqo ubushushu be-interlayer akufanele buwele ngaphantsi kobushushu bokufudumala.

3) I-Hydrogen okanye i-ultra-low hydrogen welding.

4) I-welding yonke eqhubekayo ye-seam kufuneka igqitywe ukuphepha ukuphazamiseka.

I-5) Xa ubeka i-welding kwindawo yokwandisa i-welding yangoku, isantya se-welding siyancipha, ngenxa yokunyusa i-welds ye-welds cross-sectional area kunye nobude, i-preheated xa kuyimfuneko.

6) Ayinakwenziwa kwisiseko somphezulu we-arc groove ngaphandle kwesidingo sokuzalisa icrater xa kutshabalala.
