1.Kwenziwa kanjaniintsimbi epholileyo?
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.
2.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-AWS E7016, i-AWS E7015 kunye nezinye i-electrode ezinokumelana nokuqhekeka okungcono.
3.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.
4.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 ayinakusetyenziswa kwi-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.
5.Kwenziwa kanjaniweld ubhedukunye neengxube zobhedu?
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 ekuqhekekeni kunye nenani elikhulu le-pores.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 ukuya kwi-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 welded joints ingafumaneka 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.
6.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.
7.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.
8.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 zeze-40 kg yentsimbi eqhelekileyo ephantsi.Ngenxa yokongezwa kwe-vanadium okanye i-titanium ethile, umgangatho wamandla wensimbi uphuculwe;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.
9.Ithini indlela yokuwelda yentsimbi ye-18 manganese molybdenum niobium?
No. 18 manganese-molybdenum-niobium intsimbi yentsimbi 50 kg high-ukuqina eqhelekileyo low-alloy intsimbi, nto leyo edla ngokusetyenziswa ekwenzeni iimveliso zokuwelda ezibalulekileyo ezifana iinqanawa zoxinzelelo oluphezulu kunye nebhoyila imigqomo.Ngenxa yamandla ayo aphezulu kunye nokuthambekela okukhulu kokuqina, amanyathelo okufudumeza kwendawo kufuneka athathwe ngexesha le-welding yendawo.Nika ingqalelo ekomiseni i-electrode kunye nokucoca i-groove ukukhusela ukuqhekeka okubandayo okubangelwa yi-hydrogen.I-arc welding manual isebenzisa i-junction 607 kunye nezinye i-electrodes;ukuwelda okuzenzekelayo kwe-arc kusebenzisa i-welding wire ene-manganese ephezulu 08 kunye ne-molybdenum, kwaye inokudityaniswa ne-flux 250 okanye i-flux 350.
