01 Chii chinonzi awelded joint
A welded joint (welded joint) inoreva mubatanidzwa unobatanidza maviri kana anopfuura maworkpiece newelding. The welded joint of fusion welding inoumbwa nekudziya kwenzvimbo kubva kune yakakwirira-tembiricha inopisa sosi. Iyo welded joint ine fusion zone (weld zone), fusion mutsara, kupisa kwakakanganisika nzvimbo, uye base simbi nzvimbo, sezvakaratidzwa mumufananidzo.
02 Chii chinonzi butt joint
Chimiro chinowanzo shandiswa welding ijoini apo mativi maviri akabatana anokwenenzverwa mundege imwechete kana arc papakati pejoinhi. Hunhu hunodziya kupisa, yunifomu simba, uye nyore kuona welding mhando.
03 Chii chinonzi awelding groove
Kuti ive nechokwadi chekupinda uye kunaka kwemajoini akaiswa, uye kuderedza deformation ye welding, majoini ezvikamu zvakashongedzwa anowanzo gadziridzwa kuita akasiyana maumbirwo asati aiswa. Different welding grooves akakodzera akasiyana welding nzira uye weldment ukobvu. Mafomu anowanzo groove anosanganisira: I-shaped, V-shaped, U-shaped, unilateral V-shaped, nezvimwewo, sezvakaratidzwa mumufananidzo.
Yakajairika groove mafomu emabutt joints
04 Kufurira kweButt Joint Groove Fomu paLaser Arc Composite Welding
Sezvo ukobvu hwewelded workpiece hunowedzera, kuwana single-sided welding uye kaviri-sided kuumbwa kwepakati uye gobvu ndiro (laser simba <10 kW) inowanzova yakaoma. Kazhinji, nzira dzakasiyana dzewelding dzinofanirwa kutambirwa, sekugadzira mafomu egroove akakodzera kana kuchengetedza mamwe mapeji ekuisa, kuitira kuti uwane welding yepakati uye makobvu mahwendefa. Nekudaro, mune chaiyo yekugadzira welding, kuchengetedza docking gaps kuchawedzera kuoma kwewelding zvigadziriso. Naizvozvo, dhizaini ye groove inova yakakosha panguva yewelding process. Kana iyo groove dhizaini isinganzwisisike, kugadzikana uye kugona kwewelding kuchakanganiswa, uye zvakare kunowedzera njodzi yekuremara welding.
(1) Iyo groove fomu inokanganisa zvakananga kunaka kweiyo weld seam. Yakakodzera groove dhizaini inogona kuve nechokwadi chekuti welding waya simbi yakazadzwa zvizere mukati meweld seam, ichideredza kuitika kwekuremara kwewelding.
(2) Iyo geometric chimiro chegorofu inokanganisa nzira inotamiswa kupisa, iyo inogona kutungamira kupisa, kuwana yakawanda yunifomu yekudziya uye kutonhora, uye kubatsira kudzivirira kupisa kwekupisa uye kusara kunetseka.
(3) The groove chimiro achakanganisa muchinjikwa-sectional morphology of weld musono, uye zvichaita kuti muchinjikwa-sectional morphology of weld musono zvikuru kuenderana chaiwo zvinodiwa, zvakadai weld kupinda kudzika uye upamhi.
(4) Chimiro chakakodzera chegorofu chinogona kuvandudza kugadzikana kwewelding uye kuderedza kusagadzikana kwezvinhu panguva yewelding process, senge splash uye undercut kuremara.
Sezvinoratidzwa muMufananidzo 3, vatsvakurudzi vakawana kuti kushandisa laser arc composite welding (laser simba 4kW) inogona kuzadza groove mumatanho maviri uye maviri anopfuura, zvinobudirira kuvandudza kushanda kwewelding; A defect free welding of 20mm gobvu MnDR yakawanikwa uchishandisa matatu-layer laser arc composite welding (laser simba re6kW); Laser arc composite welding yakashandiswa kukwenenzvera 30mm gobvu yakaderera-kabhoni simbi mune akawanda akaturikidzana uye anopfuura, uye mhiri-chikamu morphology yejoini yakashongedzwa yakagadzikana uye yakanaka. Pamusoro pezvo, vatsvakurudzi vakaona kuti hupamhi hwemakona ane rectangular grooves uye kona yeY-shaped grooves ine simba guru pane nzvimbo inodzivisa. Kana hupamhi rectangular groove iri≤4mm uye kona yeGroove yakaita seY iri≤60 °, iyo cross-section morphology ye weld seam inoratidza kuputika kwepakati uye mativi emadziro notches, sezvakaratidzwa mumufananidzo.

Kufurira kweGroove Width uye Angle paMuchinjikwa Section Morphology yeWelds
05 Pfupiso
Sarudzo yefomu yegroove inoda kunyatso tarisa zvinodikanwa zvebasa rewelding, hunhu hwezvinhu, uye hunhu hwe laser arc composite welding process. Yakakodzera groove dhizaini inogona kuvandudza welding kunyatsoita uye kuderedza njodzi yekuremara kwewelding. Naizvozvo, kusarudzwa uye dhizaini yefomu yegroove chinhu chakakosha pamberi pelaser arc composite welding yepakati uye gobvu mahwendefa.
