Ukulungiswa / ukuwelda
Iinkqubo zokuwelda ezisemgangathweni zolu didi lwentsimbi zezi:
- TIG-Welding
- MAG-Welding Ucingo oluqinileyo
- Ukuwelda kweArc (E)
- Laser Beam Welding
- Ukuwelda kweArc entywiliselweyo (SAW)
Xa ukhetha isinyithi sokuzalisa, uxinzelelo lwe-corrosion kufuneka lujongwe, ngokunjalo.Ukusetyenziswa kwetsimbi ye-alloyed filler ephezulu kunokuba yimfuneko ngenxa yesakhiwo sokuphoswa kwentsimbi ye-weld.Ukushisa kwangaphambili akuyimfuneko kule ntsimbi.Unyango lobushushu emva kwe-welding ayiqhelekanga ukusetyenziswa.Iintsimbi ze-Austenitic zine-30% kuphela ye-thermal conductivity ye-non-alloyed steels.Indawo yabo yokudibanisa ingaphantsi kuneentsimbi ezingaxutywanga ngoko ke iintsimbi ze-austenitic kufuneka zidityaniswe ngegalelo eliphantsi lobushushu kunezintsimbi ezifakwe kwi-alloyed.Ukuze ugweme ukufudumala okanye ukutshisa-ngokusebenzisa amaphepha amancinci, isantya esiphezulu se-welding kufuneka sisetyenziswe.Iipleyiti ze-back-up ze-Copper zokugatya ubushushu ngokukhawuleza ziyasebenza, kanti, ukuphepha ukuqhekeka kwintsimbi ye-solder, akuvumelekanga ukuba i-surface-fuse i-copper back-up plate.Le ntsimbi ine-coefficient ephezulu kakhulu yokwandiswa kwe-thermal njengentsimbi engaxutywanga.Ngokunxulumene ne-thermal conductivity embi, ukuguqulwa okukhulu kufuneka kulindelwe.Xa ukuwelda 1.4571 zonke iinkqubo, ezisebenza ngokuchasene oku kugqwethwa (umzekelo, umva-inyathelo ukuwelda ulandelelwano, ukuwelda ngokutshintshanayo kumacala ahlukeneyo nge-double-V butt weld, isabelo se-welders ezimbini xa amacandelo amakhulu ngokufanelekileyo) kufuneka ahlonishwe ngokuphawulekayo.Kubunzima bemveliso obungaphezulu kwe-12mm i-double-V butt weld kufuneka ikhethwe endaweni ye-single-V butt weld.I-angle edibeneyo kufuneka ibe yi-60 ° - 70 °, xa usebenzisa i-MIG-welding malunga ne-50 ° yanele.Ukuqokelela kwee-weld seams kufuneka kugwenywe.Iintsimbi zokuwelda kufuneka zincanyathiselwe ngemigama emifutshane ukusuka kwenye (imfutshane kakhulu kuneentsimbi ezingafakwanga), ukuze kuthintelwe ukuguqulwa okuqinileyo, ukucutheka okanye ukugqabhuka kwentsimbi.Iiteki kufuneka zicolwe emva koko okanye ubuncinane zingabi nazintanda zecrater.1.4571 ngokunxulumene nentsimbi ye-austenitic weld kunye negalelo lobushushu obuphezulu kakhulu umlutha wokwenza iintanda zobushushu ukhona.umlutha wokuqhekeka kobushushu unokuvalelwa, ukuba intsimbi ye-weld ibonisa umxholo ophantsi we-ferrite (delta ferrite).Imixholo ye-ferrite ukuya kuthi ga kwi-10% inesiphumo esihle kwaye ayichaphazeli ukuxhathisa ukubola ngokubanzi.Owona maleko we-thinnest kangangoko kunokwenzeka kufuneka udityaniswe (ubuchule be-stringer bead) kuba isantya esiphezulu sokupholisa sinciphisa umlutha kwiintanda ezishushu.Ukupholisa okukhawulezayo okunqwenelekayo kufuneka kunqwenelwe ngelixa kufakwe i-welding ngokunjalo, ukunqanda ukuba sesichengeni kwi-intergranular corrosion kunye ne-embrittlement.I-1.4571 ifaneleke kakhulu kwi-laser beam welding (weldability A ngokuhambelana ne-DVS bulletin 3203, inxalenye ye-3).Ngobubanzi be-welding groove encinci kune-0.3mm ngokulandelelana, ubukhulu bemveliso ye-0.1mm ukusetyenziswa kweentsimbi zokugcwalisa akuyomfuneko.Ngee-welding grooves ezinkulu isinyithi esifanayo sinokusetyenziswa.Ngokunqanda i-oxidation ngomphezulu womthungo ngexesha lelaser beam welding ngokusebenzisa ukuwelda okusebenzayo ngasemva, umz. iHelium njengerhasi engasebenziyo, i-welding seam ixhathisa ukudleka njengesiseko sesinyithi.Ingozi eshushu yokuqhekeza i-welding seam ayikho, xa ukhetha inkqubo esebenzayo.I-1.4571 ikwafanelekile ukusika i-laser beam fusion nge-nitrogen okanye ukusika i-flame nge-oxygen.Imiphetho esikiweyo ineendawo ezincinci ezichaphazeleka bubushushu kwaye azinantandabuzo ezincinci kwaye zinokwakheka kakuhle.Ngelixa ukhetha inkqubo esebenzayo i-fusion cut edges inokuguqulwa ngokuthe ngqo.Ngokukodwa, zinokudityaniswa ngaphandle kokulungiswa.Ngelixa kusetyenzwa kuphela izixhobo ezingenasici njengeebhrashi zentsimbi, iipeki ze-pneumatic njalo njalo zivumelekile, ukuze ungabeki emngciphekweni i-passivation.Kufuneka ingahoywa ukuphawula ngaphakathi kwendawo yokuwelda umthungo ngeebholiti ze-oleigerous okanye ubushushu obubonisa iikhrayoni.Ukumelana ne-corrosion ephezulu yale ntsimbi engenasici isekelwe ekubunjweni kwe-homogeneous, i-compact passive layer phezu komhlaba.Imibala ye-anealing, izikali, iintsalela ze-slag, i-iron ye-tramp, i-spatter kunye nezinto ezinjalo kufuneka zisuswe, ukuze zingatshabhisi i-passive layer.Ukucoca umphezulu iinkqubo zokuxukuxa, ukugaya, ukuchola okanye ukuqhushumba (isanti ye-silica engena-iron okanye i-glass spheres) ingasetyenziswa.Ukuxubha kuphela iibrashi zensimbi ezingenasici zingasetyenziswa.Ukuchongwa kwendawo yomthungo ehlanjululweyo ngaphambili kuqhutywa ngokuntywila kunye nokutshiza, nangona kunjalo, ngokuqhelekileyo i-pickling pastes okanye izisombululo zisetyenziswa.Emva kokuvuna, kufuneka kuhlanjululwe ngokucokisekileyo ngamanzi.
Phawula
Kwimeko yokucima izinto eziphathekayo zinokusebenza kancinci.Ngokunyuka kwengqele okwenza i-magnetizability iyanda.
Inqaku elibalulekileyo
Ulwazi olunikwe kweli phepha ledatha malunga nemeko okanye ukusetyenziswa kwezinto ngokulandelelana iimveliso azikho iwaranti kwiipropati zabo, kodwa zisebenza njengenkcazo.Ulwazi, esilunika iingcebiso, luthobela amava omenzi kunye nawethu.Asikwazi ukunika iwaranti ngeziphumo zokusetyenzwa kunye nokusetyenziswa kweemveliso.
