Indlela yokuwelda intsimbi ethambileyo?
Insimbi yekhabhoni ephantsi inomxholo ophantsi wekhabhoni kunye neplastiki enhle, kwaye inokulungiswa kwiindlela ezahlukeneyo zamalungu kunye namacandelo.Kwinkqubo ye-welding, akulula ukuvelisa isakhiwo esinzima, kwaye ukuthambekela kokuvelisa ukuqhekeka kuncinci.Ngexesha elifanayo, akulula ukuvelisa iipores.Yeyona nto ilungileyo ye-welding.
Ukuwelda intsimbi yekhabhoni ephantsi nge-welding yegesi, i-arc welding manual, i-arc ye-welding ezenzekelayo, i-welding ekhuselekileyo yegesi kunye nezinye iindlela zinokufumana amajoyina adibeneyo.Musa ukufudumala ixesha elide xa usebenzisa i-welding yegesi, ngaphandle koko iinkozo kwindawo echaphazelekayo ngubushushu ziya kuba zikhulu ngokulula.Xa umdibaniso unzima kakhulu kwaye ubushushu be-ambient buphantsi, i-workpiece kufuneka ifudunyezwe kwi-100 ~ 150 ° C ukuphepha ukuqhekeka.
Indlela yokuwelda intsimbi yekhabhoni ephakathi?
Ngenxa yomgangatho ophezulu wekhabhoni yensimbi ye-carbon, i-weld seam kunye nommandla wayo ochaphazelekayo ubushushu buxhomekeke kwizakhiwo ezilukhuni kwaye zibangele ukuqhekeka, ngoko ke kufuneka kufudunyezwe malunga ne-300 ° C ngaphambi kwe-welding, kwaye ukupholisa okucothayo kuyadingeka emva kwe-welding.Inokuthi idityaniswe nge-welding yegesi, i-arc manual kunye ne-gas shielded welding.Izinto ze-Welding kufuneka zisebenzise i-junction 506, i-junction 507 kunye nezinye i-electrode ezinokumelana nokuqhekeka okungcono.
Indlela yokudibanisa i-aluminium kunye ne-aluminium alloy?
I-aluminium kunye ne-aluminiyam i-alloys ithandwa kakhulu ekuveliseni iifilimu ze-oxide ezineenkcukacha ezinkulu kunye neendawo eziphezulu zokunyibilika ngexesha le-welding.Le filimu ye-oxide iyakwazi ukufunxa umthamo omkhulu wamanzi, ngoko ke iziphene ezifana ne-slag inclusions, ukudibanisa okungahambi kakuhle, kunye ne-pores zivame ukwenzeka ngexesha le-welding.Ukongeza, ii-alloys ze-aluminium Kwakhona zixhomekeke kwiintanda ze-thermal.Ukudibanisa i-aluminium kunye ne-aluminium alloys inokwenziwa nge-gas welding okanye i-arc manual.Nangona kunjalo, ubushushu be-welding yegesi abugxininisi, kwaye ukuhanjiswa kobushushu kwe-aluminium kukhawuleza, ngoko ukuveliswa kwemveliso kuphantsi, kwaye ukuguqulwa kwe-workpiece kukhulu, ngoko kunqabile ukuba kusetyenziswe ngaphandle kwamacwecwe amancinci.Okwangoku, inani elikhulu leendlela ze-AC argon arc welding zisetyenziselwa ukuwelda i-aluminium kunye ne-aluminium alloys, kuba igxininise ubushushu, i-weld seams emihle, i-deformation encinci, ukukhuselwa kwe-argon, kwaye inokuthintela ukufakwa kwe-slag kunye ne-pores.Ukuba i-arc yezandla isetyenziselwa ukuwelda i-aluminiyam, ifanelekile kwiipleyiti ezishinyeneyo ezingaphezu kwe-4mm.
Amabanga ezintonga ze-welding ezisetyenzisiweyo ziyi-aluminium 109, i-aluminium 209 kunye ne-aluminium 309. Zonke ziyi-electrode ezisekelwe kwityuwa ezinozinzo olubi lwe-arc, ezifuna i-DC reverse power supply.

Indlela yokudibanisa i-titanium kunye ne-titanium alloys?
I-Titanium yinto esebenzayo kakhulu.Kwimeko yolwelo kunye neqinileyo ngaphezulu kwe-600 ° C, kulula kakhulu ukusabela ngeoksijini, initrogen, ihydrogen kunye nezinye iigesi ukwenza ukungcola okuyingozi kunye ne-embrittle titanium.Ke ngoko, ukuwelda kwegesi ye-oxygen-acetylene, ukuwelda kwe-arc manual okanye enye i-gas shielded welding ayikwazi ukusetyenziselwa i-titanium kunye ne-titanium alloys, kodwa kuphela i-argon arc welding, i-vacuum electron beam welding kunye ne-welding yoqhagamshelwano ingasetyenziswa.
Amacwecwe amancinci angaphantsi kwe-3mm adityaniswe yi-argon arc welding, amandla ombane aqhagamshelwe ngokuthe ngqo ngoku, ukucoceka kwegesi ye-argon ayikho ngaphantsi kwe-99.98%, umlomo kufuneka ube kufutshane kangangoko kunokwenzeka kwi-workpiece, i-welding yangoku kufuneka ibe encinci, kunye nesantya se-welding kufuneka sikhawuleze.Ukuphucula ubume bekristale kunye nokuphelisa uxinzelelo lwe-welding.
Indlela yokudibanisa ii-alloys zobhedu kunye nobhedu?
I-welding yobhedu kunye ne-alloys yobhedu inobunzima obuninzi, kuba i-thermal conductivity yabo ilungile kakhulu, ngoko kulula ukubangela iziphene ezifana nokungaphumeleli kunye nokudibanisa kakubi.Emva kwe-welding, i-workpiece iya kuba ne-deformation enkulu, kwaye i-weld kunye ne-fusion zone nayo ixhomekeke kwiintanda kunye nenani elikhulu leepores.Iimpawu zemishini yokudibanisa, ngokukodwa iplastiki kunye nokuqina kuphantsi kunezo zesiseko sesinyithi.I-gas welding ingasetyenziselwa ukuthunga ubhedu obomvu, kodwa ukusebenza kakuhle kuphantsi kakhulu, i-deformation inkulu, kwaye idinga ukufudumeza ngaphezu kwe-400 ° C, kwaye iimeko zokusebenza azilungile.Ukuwelda kwe-arc ye-Manual kunokusebenzisa i-copper 107 okanye i-electrode yobhedu engama-227, unikezelo lwamandla luguqulwa kunye ne-DC, i-arc igcinwe iphantsi kangangoko kunokwenzeka, kwaye i-linear reciprocating strip method isetyenziselwa ukuphucula i-weld shape.Hammer i-weld emva kwe-welding ukuphucula umgangatho we-weld.Ukuba i-argon tungsten i-arc welding isetyenzisiweyo, i-welded welding esemgangathweni inokufumaneka kwaye i-deformation of weldments ingancitshiswa.I-wire 201 isetyenziselwa i-welding wire.Ukuba kusetyenziswe ucingo olubomvu lwe-T2, i-flux 301 kufuneka isetyenziswe kwakhona.Unikezelo lwamandla lwamkela uqhagamshelo olulungileyo lwe-DC.I-workpiece kunye ne-welding wire kufuneka ihlambuluke ngokucokisekileyo ngexesha le-welding ukunciphisa ii-pores kunye ne-slag inclusions.Isantya esiphezulu kunye nesantya esiphezulu kufuneka sisetyenziswe xa u-welding.
Ukuwelda kwegesi ngokuqhelekileyo kusetyenziselwa ukuwelda ubhedu, kwaye ucingo lwe-welding lungaba ucingo 221, ucingo lwe-222 okanye ucingo lwe-224, njl. Ezi ngcingo ziqulethe i-silicon, i-tin, isinyithi kunye nezinye izinto, ezinokunciphisa ilahleko evuthayo ye-zinc kwi-pool etyhidiweyo. .Ngenxa yokushisa kwe-welding yegesi ephantsi, ilahleko evuthayo ye-zinc ngobhedu inokunciphisa;Idangatye elincinci le-oxidation lisetyenziselwa ukugubungela umphezulu wedama elityhidiweyo kunye nefilimu ye-zinc oxide, enokunciphisa ukuphuphuma kwe-zinc.Ukongeza, ubhedu lunokudityaniswa nge-welding ye-arc manual kunye ne-argon tungsten arc welding.
Ziziphi iimpawu zokuwelda intsimbi eqhelekileyo ephantsi?
Intsimbi eqhelekileyo ephantsi kwe-alloy yintsimbi esetyenziswa ngokuqhelekileyo yokuvelisa.Into ephambili yolu hlobo lwe-welding yensimbi kukuba indawo echaphazelekayo yokushisa i-joint inomdla omkhulu wokuqina, kwaye umxholo we-hydrogen uya kubangela ukuqhekeka okubandayo kwi-joint.Olu tyekelo lokuqina kunye nokuqhekeka okubandayo luyanda njengoko ibakala lamandla entsimbi yealloy ephantsi linyuka.
Ithini indlela yokuwelda yentsimbi ye-manganese eyi-16?
I-16 ye-Manganese yentsimbi ye-welding kufuneka isebenzise i-junction 506 okanye i-junction 507 kunye nezinye i-electrode ezisisiseko, uxhulumaniso lwe-DC reverse.Xa ukuthambekela kokuqhekeka kwesakhiwo kungekho mkhulu, iintonga ze-asidi ze-welding ezifana ne-junction 502 okanye i-junction 503 nazo zingasetyenziswa, kwaye inkqubo ye-welding ifana ne-carbon steel ephantsi;xa i-weldment iqinile kwaye ubushushu be-ambient bungaphantsi kwe-10 ° C, ukufudumeza ngaphambi kokuba kufuneke.Iziphumo eziyanelisayo zinokufumaneka nge-arc welding manual, i-arc welding ephantsi kwamanzi okanye i-electroslag welding.
Ithini indlela ye-welding yeNombolo ye-15 ye-manganese vanadium kunye neNombolo ye-15 ye-titanium yensimbi ye-manganese?
Zombini i-15 manganese vanadium kunye ne-15 ye-manganese titanium zezentsimbi ye-40 kg eqhelekileyo.Inqanaba lamandla ensimbi liphuculwe ngenxa yokongezwa kwe-vanadium okanye i-titanium;kodwa ukuwelda kwabo, izinto zokuwelda kunye neenkqubo welding ziyafana nezo 16 manganese steel.Uthelekiso luyafana.Xa i-arc isetyenziselwa i-welding automatic isetyenzisiweyo, ucingo lwe-welding lunokuba yi-08 manganese phezulu, i-08 manganese 2 silicon, kunye ne-flux 431, i-flux 350 okanye i-flux 250 inokufikelela kwiziphumo ezanelisayo.
