01 Chii chinonzijoini yakasungirirwa
Joint yakasungirirwa inoreva joint apo maworkpieces maviri kana anopfuura akabatanidzwa nekusanganisa. Joint yakasungirirwa yekusanganisa inoumbwa nekudziya kwenzvimbo kubva kunzvimbo inopisa zvakanyanya. Joint yakasungirirwa ine nzvimbo yekubatanidza (weld zone), fusion line, heat affected zone, uye base metal zone, sezvakaratidzwa mumufananidzo.
02 Chii chinonzi pfundo remagaro
Chimiro chekuwedera chinowanzoshandiswa ijoini apo zvikamu zviviri zvakabatana zvinowedera panzvimbo imwe chete kana pakati pejoini. Hunhu hwacho hunosanganisira kupisa kwakafanana, simba rakafanana, uye nyore kuona kuti welding yakanaka.
03 Chii chinonzi agoko rekushongedza
Kuti zvive nechokwadi chekuti majoini akasungirirwa anopinda uye ane mhando, uye kuderedza kushanduka kwewelding, majoini ezvikamu zvakasungirirwa anowanzo gadziriswa kuita maumbirwo akasiyana-siyana asati asungirirwa. Magonhi akasiyana ewelding akakodzera nzira dzakasiyana dzewelding uye ukobvu hweweld. Mafomu egonhi akajairika anosanganisira: I-shaped, V-shaped, U-shaped, unilateral V-shaped, nezvimwewo, sezvakaratidzwa mumufananidzo.

04 Kupesvedzera kweButt Joint Groove Form paKukwevera kweLaser Arc Composite
Sezvo ukobvu hwebasa rakasungirirwa huchiwedzera, kuwana welding ine mativi maviri uye kugadzira mapurati epakati nepakati (laser power<10 kW) kunowanzova kwakaoma. Kazhinji, nzira dzakasiyana dzewelding dzinofanira kushandiswa, dzakadai sekugadzira mafomu akakodzera e groove kana kuchengetedza mamwe maburi edocking, kuitira kuti pave nekukwesha kwe groove ine mativi nepakati. Zvisinei, mukukwesha chaiko kwekugadzira, kuchengetedza maburi edocking kunowedzera kuoma kwezvishandiso zvewelding. Naizvozvo, dhizaini ye groove inova yakakosha panguva yekukwesha. Kana dhizaini ye groove isina kunaka, kugadzikana uye kushanda zvakanaka kwe welding kuchakanganiswa zvakanyanya, uye zvinowedzerawo njodzi yekukanganisa kwe welding.
(1) Chimiro chemugero chinokanganisa zvakananga kunaka kwemugero we weld. Dhizaini yakakodzera yemugero inogona kuve nechokwadi chekuti simbi yewelding yazara zvakakwana mumugero we weld, zvichideredza kuitika kwezvikanganiso zvewelding.
(2) Chimiro chemugero chinokanganisa nzira inotamiswa nayo kupisa, izvo zvinogona kutungamira kupisa zviri nani, kuita kuti kupisa nekutonhorera zviwande zvakaenzana, uye kubatsira kudzivirira kushanduka kwekupisa uye kushushikana kusara.
(3) Chimiro chemugero chichakanganisa chimiro chemusero we weld, uye zvichaita kuti chimiro chemusero we weld chienderane nezvinodiwa chaizvo, zvakaita sekudzika kwekupinda kwe weld nehupamhi.
(4) Chimiro chakakodzera chemugero chinogona kuvandudza kugadzikana kwewelding uye kuderedza kusagadzikana panguva yekukwesha, senge kupwanya uye zvikanganiso zvakaderera.
Sezvakaratidzwa muMufananidzo 3, vaongorori vakaona kuti kushandisa laser arc composite welding (laser power 4kW) kunogona kuzadza groove muzvikamu zviviri uye mapass maviri, zvichivandudza kushanda zvakanaka kwewelding; Kubatanidzwa kweMnDR isina zvikanganiso kwakaitwa uchishandisa laser arc composite welding ine malay matatu (laser power ye6kW); Laser arc composite welding yakashandiswa kusanganisa simbi ine 30mm thick-carbon steel muzvikamu zvakawanda, uye cross-sectional morphology yewelded joint yakanga yakagadzikana uye yakanaka. Pamusoro pezvo, vaongorori vakaona kuti hupamhi hwerectangular grooves neangle yeY-shaped grooves zvine simba guru pamhedzisiro yekudziviswa kwenzvimbo. Kana hupamhi hwerectangular groove hwacho≤4mm uye kona yemugero wakaita seY iri≤60 °, chimiro chemusono we weld chinoratidza mitswe yepakati uye maburi emadziro eparutivi, sezvakaratidzwa mumufananidzo.

Pfupiso ye05
Kusarudzwa kwechimiro chemugero kunofanirwa kufunga zvakadzama nezvezvinodiwa nebasa rekubatanidza, hunhu hwezvinhu, uye hunhu hwemaitiro ekubatanidza mugero we laser arc composite. Dhizaini chaiyo yemugero inogona kuvandudza kushanda zvakanaka kwekubatanidza uye kuderedza njodzi yekukanganisa kwekubatanidza. Nokudaro, kusarudzwa nekugadzirwa kwechimiro chemugero chinhu chakakosha pamberi pekubatanidza mugero we laser arc composite welding yemaplate epakati nepakati neakobvu.
