Ukuqhekeka okubandayoizizathu: umuntu okufanele afakwe ngaphansi kokushisela lapho amandla amakhulu angadatshulwa kalula lapho epholisa ukuqina kwempahla yokushisela; izinga lokupholisa lokushisela lase sekwephuzile kakhulu ukubalekela i-hydrogen esele ekushiseleni, i-athomu ye-hydrogen eboshelwe kuma-molecule e-hydrogen endaweni enegesi ezimbotsheni ezinhle zensimbi futhi ibangele ukucindezela okukhulu, ukuze insimbi yendawo eyakhiwe ngendlela ebandayo iqhekeke. ingcindezi enkulu; ingcindezi yokushisela kanye nokuhlaziywa kokucindezeleka okuqinile okugxilwe ekugxilweni kwe-hydrogen nokuqina kwenzeka ngesikhathi esisodwa kulula ukwakha lapho kuqhekeka okubandayo.

Izinyathelo zokuvimbela: ukushisa kuqala nokupholisa kancane ngemva kokushisela, ukubola kwe-austenite yendawo ethintekile ukushisa kungaba ububanzi obanele bokushisa, ukugwema izicubu eziqinile, ngenkathi kunciphisa indima yokucindezeleka ekushiseni; i-hypothermia efika ngesikhathi ngemva kokushisela i-annealing, ukwelashwa kwe-dehydroepiandrosterone, ukuqeda ukucindezeleka okukhiqizwa ngesikhathi sokushisela, kanye nokusatshalaliswa kwe-hydrogen ngesikhathi esifanele ukuya ngaphandle; ukukhethwa kwe-electrode yohlobo lwe-hydrogen ephansi kanye ne-alkaline flux noma i-austenitic stainless stainless steel welding wire, njll., izinto ezisetshenziswayo ezidingekayo zokomiswa kanye ne-groove eqinile yokuhlanza; ukuvikela nokuqinisa i-welding eshiselwe endaweni yokuhlanza, ukugwema ukungena kwe-hydrogen; khetha imininingwane ye-welding enengqondo, usebenzisa ukuhlangana okunengqondo nokulandelana kokushisela.
