Ongororo yezvikonzero zvekutsemuka mune mamwe magadzirirwo welds inoitwa kubva kune ina mativi: macroscopic morphology yejoinhi rewelding, microscopic morphology, energy spectrum analysis, uye metallographic analysis yemid-frequency spot welding machineweldment. Kuongorora uye kuongorora kunoratidza kuti kutsemuka kwewelding kunokonzerwa nemasimba ekunze, zvakanyanya nekuda kwekuvapo kwekuremara kwakakura, nemaitiro asina kufanira welding uye kusacheneswa kwakaringana kwenzvimbo yewelding ndiyo inonyanya kukonzera kukanganisa uku. Pazasi pane akati wandei matambudziko anotungamira mukutsemuka kwemajoini:
Crystalline inoputika:
Munguva yekusimba uye crystallization yedziva rewelding, mitswe inoumba pamwe nemiganhu yezviyo zve weld metal nekuda kwekristalllization segregation uye shrinkage kushushikana uye kunetseka. Kutsemuka uku kunoitika chete mukati meweld.
Liquation cracks:
Munguva yewelding, pasi pesimba repamusoro tembiricha mukupisa kupisa kutenderera, intergranular simbi padhuze ne weld musono mu interlayers of multi-layer welds inogona kunyungudika zvakare nekuda kwekupisa. Pasi peimwe shrinkage stress, mitswe inokura ichitevedza miganho yezviyo zve austenite, chiitiko chinombonzi chinobvarura kupisa.
High-temperature low-ductility cracks:
Mushure mekupedzwa kwechikamu chekristallisation chemvura, sezvo simbi yakashongedzerwa inotanga kutonhora kubva kune iyo ductile kudzoreredza tembiricha, kune zvimwe zvinhu, kana yatonhodzwa kune imwe tembiricha yemhando, iyo ductility inodzikira nekuda kwekudyidzana kwe strain rate uye metallurgical factor, inotungamira. kutsemuka pamwe chete nemiganhu yezviyo zve welded joint metal. Rudzi urwu rwekutsemuka runowanzoitika munzvimbo inobatwa nekupisa iri kure kubva pamutsetse wefusion pane kutsemuka kwe liquation.
Reheat cracks:
Mushure mekuputira, panguva yekushushikana kwekupisa kurapwa kana pasina chero kupisa kupisa, mitswe inokura pamwe neaustenite zviyo miganhu ye weld simbi pane imwe tembiricha pasi pemamiriro chaiwo. Kupisa patsva inyaya yakakosha mukubatisa simbi dzepasi-alloy dzakakwirira-simba, kunyanya muplate gobvu welds ye low-alloy high-carbon steels uye simbi dzisingapi kupisa dzine huwandu hukuru hwe carbide-forming elements (senge Cr. , Mo, V). Kubata nekukanganisa uku kunotora nguva uye kune zvakakosha pakugadzira.
Suzhou Agera Automation Equipment Co., Ltd. inyanzvi mukugadzira otomatiki gungano, welding, midziyo yekuyedza, uye mitsara yekugadzira, inonyanya kushanda maindasitiri akadai semidziyo yemumba, kugadzira mota, simbi simbi, uye 3C zvemagetsi. Isu tinopa akajairwa welding michina, otomatiki welding michina, uye gungano welding mitsara yekugadzira zvinoenderana nezvinodiwa nevatengi, tichipa akakodzera yakazara otomatiki mhinduro kubatsira makambani kukurumidza kushandura kubva kune yechinyakare nzira dzekugadzira kuenda kune yepamusoro-yekupedzisira nzira dzekugadzira. Kana iwe uchifarira yedu otomatiki michina uye mitsara yekugadzira, ndapota taura nesu: leo@agerawelder.com
