Longitudinal Submerged-arc Welded(LSAW) Umbhobho wamkela itekhnoloji ye-arc welding entywilayo, usebenzisa i-filler welding, i-particle yokukhusela i-flux engcwatywe i-arc.
I-LSAW sisishunqulelo sesiNgesi se-arc entywiliselweyo edityanisiweyo yentsimbi yomthungo ethe ngqo.Inkqubo yemveliso ye-arc edityanisiweyo yentsimbi yomthungo ibandakanya iteknoloji yokwenza i-JCOE, i-coil eyenza iteknoloji ye-arc welding ephantsi kunye ne-UOE yokwenza iteknoloji.
Inkqubo yokwenziwa koMbhobho weLongitudinal Submerged-arc Welded(LSAW) imi ngolu hlobo lulandelayo:
Ukukhangela ipleyiti yeUltrasonic → ukugoba komphetho → ukugoba kwangaphambili → ukwenza → ukuwelda kwangaphambili → i-welding yangaphakathi→ i-welding yangaphandle → Ukuhlolwa kwe-Ultrasonic → Ukuhlolwa kwe-X-ray → Ukwandisa → uvavanyo lwe-hydraulic →l.I-Chamfering → Uhlolo lwe-Ultrasonic → Uhlolo lwe-X-reyi → uhlolo lwamasuntswana omagnetic ekupheleni kwetyhubhu

Uvavanyo lweHydrostatic
Uvavanyo lwe-NDT (RT).
Uvavanyo lwe-NDT (UT).
Ukugoba uvavanyo-ubude obaneleyo bombhobho buya kuma bugobe bubanda nge-90 ° malunga ne-cylindrical mandrel.
Uvavanyo lokucaba-Nangona uvavanyo lungafuneki, umbhobho uya kuba nakho ukuhlangabezana neemfuno zovavanyo lokuthambisa.
Uvavanyo lwe-Hydrostatic-ngaphandle kokuba kuvunyelwe, ubude bombhobho ngamnye buya kufakwa kuvavanyo lwe-hydro-static ngaphandle kokuvuza ngodonga lombhobho.
Uvavanyo lombane olungonakaliyo-njengenye indlela yovavanyo lwe-hydro-static, umzimba opheleleyo wombhobho ngamnye uya kuvavanywa ngovavanyo lombane olungonakaliyo.apho uvavanyo lombane olungonakalisiyo lwenziwayo, ubude buya kuphawulwa ngoonobumba”NDE”
Uvavanyo lwe-ultrasonic
Uviwo lwangoku lwe-eddy
Umbhobho ongenanto, iingubo ezimnyama (ezilungiselelwe);
Zombini ziphela kunye nabakhuseli bokugqibela;
Isiphelo esicacileyo, i-bevel end;
Ukumakisha.
| Ngaphandle Ububanzi | Idayamitha yangaphandle yeemfumba zemibhobho ayinakwahluka ngaphezu kwe-±1% ukusuka kwidayamitha yangaphandle echaziweyo. | ||
