Hangoo tech (seko machinery), iyo ine makore makumi maviri ezviitiko mukukura uye kugadzirwa kwe Simbi isingabudise maindasitiri eindasitiri yekugadzira mari yekugadzira mari , anozokutora kuti unzwisise mamiriro ezvinhu akasiyana ezvekupedza-kwakakanganiswa panguva yekuita mhandara.
Iyo inopisa-yakakanganiswa zone (HAZ) yeWelding yakasiyana neWeld. Telding seams inogona kugadziriswa, raikudziridzwa uye yakagadziriswa tolding maitiro kuburikidza nemakemikari kuumbwa kwesimbi yesimbi kuitira kuti ive nechokwadi chekuita zvinodiwa pakuita. Nekudaro, hazvigoneke kugadzirisa mashandiro etsiva-yakakanganiswa nzvimbo kuburikidza nemakemikari kuumbwa. Iro dambudziko rekuparadzaniswa zvisina kufanana rinoitika rinongoitika pasi pechiitiko chekufamba kwekufamba. Zvekare zvigaro zvezvinyorwa, izvo zvinetso zvina zvezvidiridzi, kuzvidza, kuomesa, uye kupfava kwenzvimbo yekupisa-kupisa inonyanya kutariswa, pamwe nekuregerera mabasa, uye kupokana zvivakwa, uye kuramba zvinhu zvecrorsion. Izvi zvinofanirwa kusarudzwa maererano nezvakananga kushandisa zvinodiwa zvechimiro chakarongeka.
1. Kuomesa kweWelding kupisa-kwakakanganiswa nzvimbo
Kuomesa kweiyo inobata nzvimbo yekupisa-inokanganisa inoenderana nemakemikari kuumbwa uye kutonhora mamiriro ezvinyorwa zvibodzwa zvekusungwa. Iyo yakakosha kuratidza zvinhu zvechimiro chesimbi yekufambisa chesimbi dzakasiyana. Iyo bvunzo yekuomesa iri nyore kwazvo. Naizvozvo, nzvimbo yepamusoro yakaoma yeHmax yeiyo inowanzoshandiswa yekupisa-inokanganiswa nzvimbo (kazhinji muFelusion Zone) inoshandiswa kutonga mashandiro etsika-yakakanganiswa nzvimbo. Inogona kushandiswa zvisina kukodzera kufanotaura kuoma, brittleness uye kupaza kudzikisira kwenzvimbo inopisa-yakakanganiswa. Mumakore achangopfuura, HMX yeHaz yave ichinzi chiratidzo chakakosha pakuongorora welderability. Inofanira kunongedzerwa kuti kunyangwe musangano rimwe chete, pane zvimwe zvakawanda zvakasiyana. Izvi zvine hukama zvakanyanya necarbon zvemukati yeiyo base simbi, leloy kuumbwa uye kutonhora mamiriro. Naizvozvo, zvinokurudzirwa kushandisa simbi inogadzirwa neyakavimbika uye yenguva dzose mugadziri weWelding kuti ive nechokwadi chakagadzikana mhando.
2. Mbriketi yekupisa kupisa nzvimbo yakakanganiswa
Mbriketi yeiyo inobata nzvimbo yekupisa-yakakanganisika inowanzoita chikonzero chikuru chekupaza uye kutadza kwenhamba yekubatanidza majoini. Maererano neiyo iripo yedata yedata uye ruzivo, mafomu embri anosanganisira crystal crybrittlement
1) coarse crystal embrittlement. Nekuda kwemhedzisiro yemubhadharo wekudyara, kudzora zviyo kunoitika pedyo nenzvimbo yekufudza uye yakanyanya kuwandisa yenzvimbo yakavanzika. Zviyero zvemakwenzi zvichikanganisa zvakanyanya iyo brittleness of the base yesimbi chimiro. Kazhinji, yakakura saizi yeiyo yeiyo yeiyo yeiyo yeiyo yejira tembiricha.
2) kutsvaira uye kumprittlement. Munguva yekukwegura kana yekuwedzera, carbides, nitrides, intermitallic makomputa uye mamwe mitezo yemisangano ichave yakagadzirirwa mukugadzirisa kwakasimba. Aya mahonyeti matsva ezvikamu anowedzera simba, kuomarara uye brittleness of simbi kana alloys. Ichi chiitiko chinodaidzwa kuti manyorerwo embri.
3) Mbri embri. Mbriketi inokonzerwa nechitarisiko cheBrittle uye yakaoma chimiro muWelding Haz inonzi chimiro cheMbbrttlement. Nekuti zvinowanzoshandiswa kuderera-kabhoni yakaderera-leady yakakwira-simba, iyo mbbrittlement yeHaz inonyanya kukonzerwa ne maComenter, kumusoro Bhaini, uye kuunganidza worshanstatten. Asi kune zvimbudzi nekaruru yezvikamu zvemukati (kazhinji ≥0.2%), chimiro chechigadzirwa chinonyanya kukonzerwa neakakwirira-kabhoni martensite.
4) Iyo inopisa inoshamwaridzana kuchembera kweHaz. Chimiro cheTalting chinoda kuongororwa muitiro yekugadzira, senge zvinhu, kuveura, kutonhora, gasi kucheka, kutonhora uye kune kumwe kugadzirwa uye kumwe kuitwa. Iyo yemunharaunda yemunharaunda uye gadziriro yepurasitiki inokonzerwa nekugadziriswa uku kuve nesimba rakakura pane zvinomirirwa neHaz haina. Mbiritendi inokonzerwa nematanho ekugadzirisa aya anonzi iyo Fermal Drain Kuchera Mbrid. Mbiritoro yekukwegura inogona kukamurwa kuita Static Stabrin Kuchembera EMBTTLEment uye Dynamic Strain Kuchera Mbbrittlement. Kazhinji, 'Bhurawuza Brittleness ' ndedzipi dzechisimba chesimba rekunetseka nekukwegura.
3. Kuzvidza kwekupisa kupisa nzvimbo yakakanganiswa
Welding Haz inzvimbo isina yunifomu muchimiro uye kuita. Iyo Fenion zone uye nzvimbo yekaka-yakakwenenzverwa inonyanya kufarirwa kumbri uye ndedzipi dzisina kusimba nzvimbo yeiyo yakazara yakabatanidzwa. Naizvozvo, zvinodikanwa kuvandudza kuoma kweiyo yakavanzika Haz. Maererano nekutsvaga, nzira mbiri dzinotevera dzinogona kushandiswa kuToughen the Haz.
1) kudzora sangano. Simbi yakaderera-lexy inofanira kudzora carbon zvemukati, kuti iyo yekupa simba system is a system inosimbisa yeyakaderera-carbon tarisiro yezvinhu zvakawanda zvekupa mari. Nekuda kweizvozvo, pasi pemamiriro ezvinhu ekutonhora weWalking, Haz anogoverwa nezvisungo zvekuparadzira, uye akaderera-carbon-merdenite, akaderera bhaini uye akaenzana emari anogadzirwa muchimiro chayo nekuomesara. Kechipiri, kusarongeka kwemiganhu yezviyo inofanirwa kudzorwa zvakanyanya sezvinobvira.
2) Kuzvidza kurapwa. Zvimwe zvakakosha zvivakwa zvinowanzoshandisa post-weld kupisa kurapwa kuti uvandudze kuita kwejoini. Nekudaro, zvimwe zvakakura uye zvakaomarara zvivakwa zvinotora kurapa kwemuno kupisa, izvo zvakawedzera kuoma mukushanda chaiko. Naizvozvo, kusarudzwa kwakakodzera kweanotyisa kupisa, kuumbwa kwekutenderera kwakaringana, uye kugadzirisa kwekunzwisisa uye kupembedza nekudziya kwekudzidzira zviyero zvinoshanda zvekuvandudza kutambisa.
Mukuwedzera, kune dzimwe nzira dzekuvandudza kuomarara kweHaz. Semuenzaniso, simbi yakaisvonaka inotora basa rekudzorwa kuti rinyatsonyedze zviyo zvepamberi, izvo zvichavandudza zvakare kuomarara kwezvinhu izvi. Izvi zvinoenderana nechinhu chezvinhu zvesimbi yetsika pachayo uye chine chekuita nehunyanzvi hwekunyepedzera.
Chechina, iyo nyorovesa yeiyo inodzivirira kupisa-inokanganisa nzvimbo
Zvemasimbi kana alloys akasimbiswa nebasa rinotonhora achiomesa kana kurapa kwekurapa usati watama, madhigirii akasiyana eVector Simba anowanzoitika munzvimbo inopisa kwazvo. Iyo inonyanya kujairika ndeye yakakwirira-simba manyorerwe uye madhiri ane precipation kusimbisa uye kupararira kusimbisa, uye kupfava kana vector simba rakagadzirwa munzvimbo inopisa-yakakanganiswa mushure mekushungurudza nzvimbo. Paunenge wakanyungudika uye wakachena simbi, iyo nyorovesa degree yeHaz ine hukama neyekupisa kurapa mamiriro ezvinyorwa zvibodzwa usati waberekerwa. Iyo yakadzika tembiricha yekudziya yekudzima uye yekushambadzira isati yasununguka isati yasvitsa simbi yekutsaura, iyo yakakura kusimbisa, iyo yakanyanya kuwanda-yekutenderera ichapfava ichaitika. Nhamba huru yeiyo inoshanda yekutsvaga data inoratidza kuti kana akasiyana maWelding nzira uye akasiyana maWire masimba anoshandiswa, nzvimbo iri pachena yekupfava mune haz ndiko kupisa pakati peA1-A3.
