1) Alkawari
A cikin 1960s, Kamfanin Mota na Toyota ya fara karɓar fasaha mara waya ta tela. Shi ne a haɗa zanen gado biyu ko fiye tare ta hanyar walda sannan a buga su. Waɗannan zanen gado na iya samun kauri daban-daban, kayan aiki, da kaddarorin. Saboda ƙarin buƙatu masu girma don aikin mota da ayyuka kamar ceton makamashi, kariyar muhalli, amincin tuƙi, da sauransu, fasahar ɗinkin walda ta ɗinki ta jawo hankali sosai. Plate walda na iya amfani da tabo waldi, walƙiya butt waldi,waldi na Laser, hydrogen Arc waldi, da dai sauransu A halin yanzu.waldi na LaserAn fi amfani da shi a cikin bincike na ƙasashen waje da kuma samar da faifan tela-welded.
Ta hanyar kwatanta gwajin gwaji da sakamakon ƙididdiga, sakamakon yana cikin yarjejeniya mai kyau, tabbatar da daidaiton samfurin tushen zafi. An ƙididdige faɗin kabu ɗin walda a ƙarƙashin sigogin tsari daban-daban kuma an inganta su a hankali. A ƙarshe, an karɓi rabon makamashi na katako na 2: 1, an shirya katako guda biyu a layi daya, babban katakon makamashi yana tsakiyar tsakiyar kabu, kuma ƙaramin wutar lantarki yana kan farantin mai kauri. Yana iya yadda ya kamata rage weld nisa. Lokacin da katako guda biyu suna da digiri 45 daga juna. Lokacin da aka shirya, katako yana aiki akan farantin mai kauri da bakin ciki bi da bi. Saboda raguwar ingantaccen diamita na katako na dumama, girman walda kuma yana raguwa.
2) Aluminum karfe dissimilar karafa
Binciken na yanzu yana zana waɗannan shawarwari masu zuwa: (1) Yayin da adadin makamashi na katako ya karu, kauri na tsaka-tsakin tsaka-tsakin tsaka-tsakin tsaka-tsaki a cikin matsayi guda na weld / aluminum alloy interface a hankali yana raguwa, kuma rarrabawa ya zama na yau da kullum. Lokacin da RS = 2, kauri na dubawa IMC Layer yana tsakanin 5-10 microns. Matsakaicin tsayin “alura-kamar” IMC kyauta yana tsakanin microns 23.

Kauri Layer IMC a walda / aluminum gami da ke dubawa kusa da karfe / aluminum gami haɗin haɗin gwiwa ya fi girma, tare da matsakaicin kauri na 23.7 microns. . Yayin da rabon makamashin katako ya karu, lokacin da RS = 1.50, kauri na Layer IMC a walda / aluminum alloy interface har yanzu yana da girma fiye da kauri na tsaka-tsakin tsaka-tsakin tsaka-tsaki a cikin yanki ɗaya na serial dual biam.
3. Aluminum-lithium gami T-dimbin haɗin gwiwa
Game da kaddarorin inji na Laser welded gidajen abinci na 2A97 aluminum gami, masu bincike sun yi nazarin microhardness, tensile Properties da gajiya Properties. Sakamakon gwajin ya nuna cewa: yankin walda na Laser welded haɗin gwiwa na 2A97-T3/T4 aluminum gami yana da taushi sosai. Matsakaicin yana kusa da 0.6, wanda galibi yana da alaƙa da rushewa da wahala mai zuwa a hazo na lokacin ƙarfafawa; Ƙarfin ƙarfin haɗin gwiwa na 2A97-T4 aluminum gami da welded ta IPGYLR-6000 fiber Laser zai iya kaiwa 0.8, amma filastik yana da ƙasa, yayin da fiber IPGYLS-4000.waldi na LaserƘarfin ƙarfin laser welded 2A97-T3 aluminum gami gidajen abinci yana kusan 0.6; lahani na pore shine asalin fashewar gajiya a cikin 2A97-T3 aluminum gami da welded gidajen abinci.
A cikin yanayin aiki tare, bisa ga nau'ikan nau'ikan kristal daban-daban, FZ galibi ya ƙunshi lu'ulu'u na ginshiƙai da lu'ulu'u masu daidaitawa. Lu'ulu'u na ginshiƙan suna da yanayin haɓakar EQZ na epitaxial, kuma kwatancen haɓakar su yana kan layin haɗin gwiwa. Wannan shi ne saboda saman hatsin EQZ wani nau'in ƙwayar cuta ne wanda aka shirya, kuma zafi a wannan hanya shine mafi sauri. Sabili da haka, axis na farko na crystallographic axis na layin haɗin kai tsaye yana girma da kyau kuma an iyakance bangarorin. Yayin da lu'ulu'u na ginshiƙi ke girma zuwa tsakiyar walda, tsarin tsarin halittar ya canza kuma an kafa dendrites na columnar. A tsakiyar walda, zazzabi na narkakken tafkin yana da girma, yawan zafin zafi iri ɗaya ne a kowane bangare, kuma hatsi suna girma daidai da kowane kwatance, suna samar da dendrites daidai. Lokacin da babban axis crystallographic na dendrites daidai yake daidai da samfurin jirgin sama, ana iya lura da nau'ikan hatsi masu kama da furanni a cikin lokaci na ƙarfe. Bugu da kari, abin ya shafa supercooling na gida aka gyara a cikin Weld zone, equiaxed lafiya-grained makada yawanci bayyana a cikin welded kabu yankin na synchronous yanayin T-dimbin yawa hadin gwiwa, da kuma hatsi ilimin halittar jiki a cikin equiaxed lafiya-grained band ne daban-daban daga. ilimin halin dan Adam na EQZ. Siffar iri ɗaya. Saboda tsarin dumama yanayin yanayi daban-daban TSTB-LW ya bambanta da na yanayin daidaitawa na TSTB-LW, akwai bambance-bambance a bayyane a cikin macromorphology da microstructure ilimin halittar jiki. Yanayin haɗin gwiwa mai siffa TSTB-LW mai nau'in nau'in ya ɗanɗana zagayowar thermal guda biyu, yana nuna halayen tafki mai narkakkarwa sau biyu. Akwai layi mai haɗaɗɗiyar zahiri na biyu a cikin walda, kuma narkakkar tafkin da aka samar ta hanyar waldawar thermal conduction ƙarami ne. A cikin yanayin iri-iri na TSTB-LW, zurfin shigar walda yana shafar tsarin dumama na walƙiyar thermal. dendrites na columnar da dendrites masu daidaitawa kusa da layin haɗin na biyu suna da ƙananan iyakoki na ƙasa kuma suna canzawa zuwa ginshiƙai ko lu'ulu'u na salula, yana nuna cewa Tsarin dumama na waldawar thermal conductivity yana da tasirin magani mai zafi akan zurfin shigar walda. Kuma girman hatsi na dendrites a tsakiyar weld na thermal conductive shine 2-5 microns, wanda ya fi ƙanƙanta fiye da girman hatsin dendrites a tsakiyar walƙiya mai zurfi (5-10 microns). Wannan ya danganta da matsakaicin dumama walda a bangarorin biyu. Zazzabi yana da alaƙa da ƙimar sanyaya na gaba.
3) Ka'ida ta biyu-bim Laser foda cladding waldi
4)High solder hadin gwiwa ƙarfi
A cikin jerin gwano na biyu na Laser-sutturar ajiya na biyu, tunda aka rarraba manyan katako biyu a gefe na gada, da yawa da sakamakon solder gidajen abinci ne tsaye zuwa gada waya. Hanyar waya tana da ɗan tsawo. Hoto na 3.6 yana nuna kayan haɗin gwal ɗin da aka samu ta hanyar katako guda ɗaya da katako mai katako na Laser foda biyu. A lokacin aikin walda, ko yana da katako biyuwaldi na Laserhanya ko guda-bimwaldi na LaserHanyar, wani narkakkar tafkin yana samuwa akan kayan tushe ta hanyar zafi. Ta wannan hanya, da narkakkar tushe abu karfe a cikin narkakkar pool iya samar da wani karfe bond tare da narkakkar kai-fluxing gami foda, game da shi cimma waldi. Lokacin amfani da Laser na katako mai dual don waldawa, hulɗar da ke tsakanin katakon Laser da kayan tushe shine hulɗar tsakanin sassan aikin na katakon Laser guda biyu, wato, hulɗar tsakanin wuraren tafki guda biyu na narkakkar da laser akan kayan. . Ta wannan hanyar, sakamakon sabon haɗin gwiwa Yankin ya fi girma fiye da na katako guda ɗayawaldi na Laser, don haka solder gidajen abinci samu ta biyu-bimwaldi na Lasersun fi ƙarfin katako guda ɗayawaldi na Laser.
2. High solderability da repeatability
A cikin guda-bimwaldi na Lasergwaji, tun da cibiyar mayar da hankali tabo na Laser kai tsaye aiki a kan micro-gada waya, da gada waya yana da matukar high bukatun gawaldi na Lasertsarin sigogi, kamar m Laser makamashi yawa rarraba da m gami foda kauri. Wannan zai haifar da karyewar waya yayin aikin walda har ma kai tsaye ya sa wayar gadar ta yi tururi. A cikin biyu-bim Laser waldi Hanyar, tun da mayar da hankali tabo cibiyoyin na biyu Laser katako ba kai tsaye aiki a kan micro-gada wayoyi, da stringent bukatun ga Laser waldi tsari sigogi na gada wayoyi suna rage, da weldability da kuma repeatability suna ƙwarai inganta. .
