2205 2507 Austenitic Ferritic Duplex Stainless Steel imibhobho edityanisiweyo edityanisiweyo (Ukuxhathisa kwi-kloride corrosion)
Ukuveliswa kwe-2205 kunye ne-2507 imibhobho ye-welding yensimbi engenasici idla ngokubandakanya la manyathelo alandelayo:
Ukulungiselela izinto ezikrwada
Khetha i-2205 okanye i-2507 sheet okanye i-strip efanelekileyo kwi-ASTM A790 / A789 okanye imigangatho ye-EN 10216-5.
Ukubumba
Iphepha lenkqubo okanye umcwe kwimilo yombhobho ngokuqengqeleka okubandayo okanye inkqubo yokuzoba ebandayo.
Ukuwelda
Ukusebenzisa i-TIG (i-tungsten pole argon arc welding) okanye i-MIG (i-metal inert gas protective welding). Iiparamitha ze-welding kufuneka zilawulwe ngokungqongqo ngexesha lenkqubo ye-welding ukuqinisekisa umgangatho we-weld.
Unyango lobushushu
Emva kwe-welding, unyango oluluqilima lwesisombululo lunokufuneka ukubuyisela ukuxhathisa ukubola kunye neempawu zomatshini wezinto eziphathekayo.
Ukuhlolwa kunye nokuhlolwa
Ukuqhuba uvavanyo olungonakalisi lombhobho odityanisiweyo, njengokufunyanwa kwe-ultrasonic, ukufumanisa i-radiographic, njl., Ukuqinisekisa ukuba i-weld ayinaziphene. Uvavanyo lweempawu zoomatshini kunye novavanyo lokumelana nokubola lwenziwa ngaxeshanye.
Unyango lomphezulu
Ngokwemfuno, unyango lombhobho odityanisiweyo, njenge-pickling, passivation, njl., Ukuphucula ukuxhathisa ukubola.
Ukupakishwa kunye nokuhanjiswa
Ukupakishwa kwemibhobho edityanisiweyo eqinisekisiweyo ukuqinisekisa ukuba akukho monakalo ngexesha lothutho.
I-2205 kunye ne-2507 izigaba ezibini zemibhobho yensimbi engenasici ifanelekile kwizicelo ezininzi zemizi-mveliso ngenxa yokumelana nokugqwesa kwe-chloride. Xa ukhetha kwaye usebenzisa ezi zixhobo, qinisekisa ukuba imigangatho efanelekileyo kunye neenkcukacha zilandelwa ukuqinisekisa ukusebenza kunye nokhuseleko lwezixhobo.
