1. Ukuhlolwa kwembonakalo yeizifakelo zemibhobho yengqiniba: ngokubanzi, uphando lwamehlo yindlela ephambili. Ngokuhlolwa kwenkangeleko, inokufumana iziphene zembonakalo ye-welding elbow fittings, kwaye ngamanye amaxesha isebenzise i-5-20 yeglasi yokukhulisa iglasi ukuphanda. Okufana nokuluma komphetho, i-porosity, i-welding tumors, i-cracks yomhlaba, ukufakwa kwe-slag kunye nokungena, njl njl.

2. Ukuhlolwa okungonakalisiyo kwezixhobo zombhobho we-elbow: ukuhlolwa kwe-slag, i-porosity, ii-cracks kunye nezinye iziphene ezifihliweyo kwi-weld. Ukuhlolwa kwe-X-ray kukusebenzisa i-X - ray ukuthatha imifanekiso ye-welding seam, ngokuhambelana nombono ongalunganga wokugqiba ukuba ngaba kukho iziphene zangaphakathi, inani kunye nohlobo lweziphene. Ngoku eyona nto isetyenziswa kakhulu kukukhethwa kokuhlolwa kwe-X-ray, kunye nokuhlolwa kwe-ultrasonic kunye nokuhlolwa kwamagnetic. Emva koko ngokweemfuno zezakhono zemveliso ukuchonga ukuba i-weld ifanelekile. Ngeli xesha, amaza abonakalisiweyo avela kwisikrini. Ngokuthelekisa kunye nokuchongwa kwala maza abonakalisiweyo ngamaza aqhelekileyo, ubungakanani kunye nendawo yesiphene inokumiselwa. Ukufumanisa impazamo ye-Ultrasonic kulula kakhulu kune-X-reyi, ngoko isetyenziswa ngokubanzi. Nangona kunjalo, ukuhlolwa kwe-ultrasonic kunokugwetywa kuphela ngamava okusebenza, kwaye ayikwazi ukushiya isiseko sokuhlola. Umbhobho we-ultrasonic uthunyelwa kwi-probe kwintsimbi, kwaye xa ifikelela kwi-metal-air interface, i-refracts kwaye idlule kwi-weld. Ukuba kukho iziphene kwi-weld, i-beam ye-ultrasonic iya kubonakaliswa kwi-probe kwaye ithwalwe, kuba iziphene zangaphakathi ze-weld surface ayinzulu kwaye ukubonakala kwamaqhekeza amancinci kakhulu, ukufunyanwa kwe-magnetic flaw kungasetyenziswa.

3. Iimpawu zomatshini zovavanyo lombhobho we-elbow: uvavanyo olungonakalisi lunokufumana iziphene zendalo ze-weld, kodwa alunakucacisa iipropathi zoomatshini zentsimbi kwindawo echaphazelekileyo yobushushu, ke ngamanye amaxesha ukwenza uxinzelelo, impembelelo, ukugoba kunye. eminye imifuniselo kwijoyinti edityanisiweyo. Olu vavanyo lwenziwa yibhodi yovavanyo. Ipleyiti yokuvavanya esetyenzisiweyo idityaniswe kakuhle kunye ne-longitudinal seam ye-cylinder ukuqinisekisa ukuba iimeko zokwakha ezingaguqukiyo. Emva koko iimpawu zomatshini zeplate yokuvavanya zivavanywa. Enyanisweni, kuphela i-welding joints of steel entsha ivavanywa kule nkalo.

4. Uvavanyo loxinzelelo lombhobho we-elbow kunye novavanyo loxinzelelo: kwiimfuno zokutywinwa kwesitya soxinzelelo, uvavanyo loxinzelelo lwamanzi kunye (okanye) uvavanyo loxinzelelo, ukujonga ukutywinwa kunye nekhono loxinzelelo lwe-weld. Indlela yokufaka i-1.25-1.5 amaxesha oxinzelelo olusebenzayo lwamanzi okanye ilingana noxinzelelo lokusebenza lwegesi (ubukhulu becala ngomoya) kwisikhongozeli, uhlale ixesha elithile, uze uphande ukuhla koxinzelelo kwisitya, kwaye uphande ukuba kukho ukuvuza ngaphandle, ngokutsho oku kunokuchonga ukuba i-weld ifanelekile na.
