Ukuhlolwa kwe-post-weld non-sruption test

Iindlela zokuvavanya ezingonakalisi zisetyenziswa ngokuqhelekileyo

1.UT (Uvavanyo lweUltrasonic)

--Umgaqo: Amaza omsindo asasaza kwizinto eziphathekayo, xa kukho ukungcola koxinaniso olwahlukeneyo kwizinto eziphathekayo, amaza esandi aya kubonakala, kwaye umphumo we-piezoelectric wento yokubonisa iya kuveliswa kwisiboniso: into ekwiprobe inokuguqula. amandla ombane abe ngamandla omatshini, kunye nefuthe eliguqukileyo, amandla omatshini aguqulwa abe ngamandla ombane I-Ultrasonic longitudinal wave kunye ne-shear wave / i-shear wave, i-probe yahlulwe ibe yi-probe ethe tye kunye ne-oblique probe, i-probe ethe tye ikakhulu ibona izinto eziphathekayo, i-oblique probe ikakhulu. ibhaqa iiwelds

—-Izixhobo zovavanyo lweUltrasonic kunye namanyathelo okusebenza

Izixhobo: Umtshini we-ultrasonic flaw, probe, ibhloko yovavanyo

Inkqubo:

Ibrashi eqatywe icouplant.Khangela.Vavanya imiqondiso ebonisiweyo

——Iimpawu zokubona kwe-Ultrasonic

Ukubekwa kwe-Three-dimensional kuchanekile, ukuvumela kuphela ukusuka kwicala lecandelo ukuba lisebenze, ubukhulu bokubona ubukhulu obukhulu - ukuya kuthi ga kwi-2 yeemitha okanye ngaphezulu, bunokubona isitshixo esingapheliyo - uhlobo olucwangcisiweyo olungapheliyo, izixhobo ezilula ukuthwala, ezifuna inqanaba lokukhangela isiphene. Iphezulu, ubukhulu bufuneka ngokubanzi kungabi ngaphantsi kwe-8mm, indawo egudileyo

——Ityuwa encamatheliswayo esetyenziselwa ukufumanisa isiphene kwi-ultrasonic iphezulu kakhulu, kwaye kufuneka icocwe ngoko nangoko emva kokubhaqwa kwesiphene.

I-paste esetyenziselwa ukukhangela i-ultrasonic flaw kwi-industry industry enzima inomxholo ophezulu kakhulu wetyuwa, kwaye ukuba ayicocwanga ngexesha, iya kuba nefuthe elikhulu kumgangatho we-anti-corrosion coating.

Kwiingubo eziqhelekileyo zokulwa ne-corrosion, umsebenzi wayo oyintloko kukwahlula umoya okanye amanzi (i-electrolyte) kwindawo ekhuselweyo, kodwa oku kukwahlula akuyiyo ngokupheleleyo, emva kwexesha elithile, ngenxa yoxinzelelo lwe-atmospheric, umoya okanye amanzi (i-electrolyte) iya kusala. ngena kwindawo ekhuselweyo, emva koko indawo ekhuselweyo iya kuvelisa i-chemical reaction kunye nokufuma okanye amanzi (i-electrolyte) emoyeni, ngelixa i-corroding surface ekhuselweyo.Iityuwa zinokusetyenziswa njengezinto ezinceda ukukhawulezisa izinga lokutya, kwaye okukhona ityuwa iphezulu kokukhona isantya sokutya sikhawuleza.

Kumashishini oshishino olunzima, kukho umsebenzi - ukufumanisa i-ultrasonic flaw, ukusetyenziswa kwe-paste (i-couplant) ityuwa iphezulu kakhulu, umxholo wetyuwa ufikelele ngaphezu kwe-10,000 μs / cm (ishishini ngokubanzi lifuna umxholo wetyuwa we-abrasive ungaphantsi. ngaphezu kwe-250 μs / cm, ityuwa yethu yamanzi asekhaya ngokuqhelekileyo imalunga ne-120 μs / cm), kulo mzekelo, ukwakhiwa kwepeyinti, i-coating iya kulahlekelwa yimpembelelo yayo yokulwa ne-corrosion kwixesha elifutshane.

Uqheliso oluqhelekileyo kukuhlambulula intlama yokubhaqa isiphene ngamanzi acocekileyo ngoko nangoko emva kokubhaqwa kwesiphene.Nangona kunjalo, amanye amashishini awanamatheli ukubaluleka kwi-anti-corrosion, kwaye ayihlambululi i-paste emva kokufunyanwa kwesiphako, okubangela ukuba kube nzima ukususa i-paste yokufumanisa impazamo emva kokumisa, echaphazela ngokuthe ngqo umgangatho wokulwa nokubola kwengubo.

Nantsi uluhlu lwedatha yolingo:

1. Idatha yetyuwa yolwelo lokufumanisa isiphene

——Umgaqo: ukusasazwa kunye nokufunxwa kwemitha - ukusasazwa kwimathiriyeli okanye i-welds, ukufunxwa kwemitha ngeefilimu.
