AWS A5.23: ECF3 Submerged Arc Welding Wire Arc Cord Wire Low-Alloy Steel

UDIDI:

AWS A5.23: ECF3 Submerged Arc Cored Wires Low-Alloy Steel

INGCACISO:

I-AWS A5.23: I-ECF3 yi-alloy ephantsi ye-alloy ehlanganisiweyo ye-electrode ye-wire electrode ye-arc entywiliweyo kwizicelo zamandla aphezulu.Kwaye idibana ne-AWS A5.23 chemistry F3, kwaye yenzelwe amanqanaba amandla okuqina ngaphezulu kwe-100 ksi.

IIMPAWU&IZINZUZO:

Iingcingo ezinomgangatho wentsimbi zinokubonelela ngamazinga aphuculweyo okubekwa xa kuthelekiswa neengcingo eziqinileyo kwiiampeges ezithelekisekayo.

Iingcingo zentsimbi zibonelela ngeeprofayili zokungena ezibanzi xa zithelekiswa neengcingo eziqinileyo kwiiparamitha ezithelekisekayo zokuwelda.

Iimfuno zemichiza yediphozithi yeWeld ziyafana nezo ze-EF3 iingcingo eziqinileyo

Idiphozithi ye-Weld idipozithi yokwakheka kweekhemikhali iqulathe ngaphantsi kwe-1% nickel

Impembelelo entle kakhulu yobushushu obuphantsi kuzo zombini iimeko ezifana ne-welded kunye noxinzelelo-luthomalalise

Ibonelela ngesakhono sokwandisa isantya sokuhamba sokuphucula imveliso

Inceda ukunqanda ukutshisa xa udityanisiwe kwimisinga ephezulu kwiingcambu kunye nezixhobo ezibhityileyo.

Ifanelekile njengenye indlela enemveliso ephezulu kwizicelo ezininzi ezisebenzisa i-EF3 ucingo oluqinileyo

Ilungele ukusetyenziswa kwizicelo zerhasi emuncu apho i-corrosion yoxinzelelo yoxinzelelo ngenxa ye-hydrogen-sulfide iyinkxalabo.

Inceda ukunciphisa umngcipheko wokuqhekeka kwizicelo ezibalulekileyo kunye neendawo zenkonzo ezinzima

AMASHISHINI:

Ukwenziwa kolwakhiwo, i-oyile & negesi, ukwenziwa kombane, izixhobo ezinzima

UHLOBO LOCINGO:

I-Metal-powder, i-metal-core wire

irect Current Electrode Positive (DCEP), Direct Current Electrode Negative (DCEN), Alternating Current (AC)

UKUGCINA:

Imveliso kufuneka igcinwe kwindawo eyomileyo, evaliweyo, kunye nokupakishwa kwayo kwangaphambili

UHLELO lwe-AWS:

IIPROPATI EZIQHELEKILEYO ZOMSHISHINI:

IIPARAMETHA EZIQHELEKILEYO ZOKUSEBENZA:

Ukugcina inkqubo yokuwelda efanelekileyo - kubandakanywa ukushisa kwangaphambili kunye nokushisa kwe-interpass - kunokuba kubaluleke kakhulu kuxhomekeke kuhlobo kunye nobukhulu bentsimbi edityanisiweyo.

Iiparamitha zibonelelwa ngeenjongo zolwazi kuphela.Onke amaxabiso aqikelelwa.Amandla ombane afanelekileyo anokwahluka (ngokuqhelekileyo ± 2 volts) ngokuxhomekeke kukhetho lokuguquguquka, ubukhulu bezinto eziphathekayo, uyilo oludibeneyo, kunye nezinye izinto eziguquguqukayo ezikhethekileyo kwisicelo.

Ngokukwanjalo, inqanaba lokwenyani lokubekwa linokwahluka ngokuxhomekeke kukhetho lokuguquguquka kunye nengcebiso yoqhagamshelwano kumgama wokusebenza.
