Intsimbi yekhabhoni ephakathi ngokuqhelekileyo ibhekisela kumxholo wekhabhoni malunga ne-0.25 ukuya kwi-0.60% ye-carbon steel.Ukuwelda kwe-arc yokwenziwa kwe-carbon steel kunye ne-welding yeempawu eziphambili ngolu hlobo lulandelayo:

1Ukuphakama komxholo wekhabhoni, ubukhulu bepleyiti, ngakumbi ukuthambekela kuqina.I-Weldment stiffer, ukupholisa ngokukhawuleza kunye nokukhethwa kweentonga akusiyo ixesha, elithandwa kukuqhekeka okubandayo.

(2) Ekubeni isiseko sesinyithi sanyibilika kumaleko wokuqala we-weld metal ratio malunga nama-30%, ngoko okukhona kuphezulu umxholo wekhabhoni we-weld, umphumo kulula ukuwelda intsimbi eshushu kunye nokuqhekeka okubandayo.

Amanyathelo athatyathwe yi-welding ye-carbon steel

(1) Ukuba kunokwenzeka, khetha i-electrode ene-hydrogen esisiseko.I-electrode enjalo kunye nokuchasana okuphezulu kokuchasana nokuqhaqhaqhaqhaqhaqhaqhaqhaqhaqhaqhaqhaqhaqhaqhaqhaqhaqhaqhaqhayolo ye-thermal.Iimeko zomntu ngamnye, ngokulawula ngokungqongqo ukushisa kwangaphambi kokushisa kunye nokunciphisa ukunciphisa isiseko sentsimbi yokungena kwi-weld carbon content kunye nezinye iindlela zenkqubo, ukusetyenziswa kwe-calcium ilmenite uhlobo lwe-electrode lunokufumana iziphumo ezanelisayo.Xa amandla adibeneyo adityanisiweyo kunye nesiseko sentsimbi ayifuni ixesha elilinganayo kufuneka lisetyenziswe kwi-electrode ephantsi ye-hydrogen ephantsi.Iplastiki yeWeld enjalo, ivelisa ukuqhekeka okubandayo kunye nokuqhekeka kwe-thermal okunobungozi obuncinci.

(2) Preheat awona manyathelo aphambili etekhnoloji yokuwelda kunye nokulungisa ukuwelda kwentsimbi yekhabhoni, ngakumbi ubukhulu be-weldment, ukuqina kukhulu, ukufudumala kulungiselelwa ukunciphisa ubulukhuni obukhulu bommandla ochaphazelekayo kunye nokuthintela ukuqhekeka okubandayo, kwaye kunokuphucula iplastiki edibeneyo.Ukufudumala ngokubanzi kunye nokufudumala okufanelekileyo kunciphisa uxinzelelo lwe-post weld residual.Umxholo wekhabhoni we-welding ezahlukeneyo ze-carbon steel welding ukushisa kwe-preheat kwaye akukho mithetho efanayo.Oku akukona nje kuphela ngenxa yokuba ukhetho lobushushu bokufudumala bugqitywe ngumxholo wekhabhoni ye-electrode, kodwa ikwachatshazelwa zezinye izinto, ezifana nobukhulu kunye nobukhulu be-weldment, uhlobo lwe-welding, i-parameters ye-welding kunye nokuqina kwesakhiwo kunye njalo njalo.
