Nhanganyaya yeNozzle
Manozzles anowanzo kufuratirwa welding yekuwedzera mune welding mashandiro. Mune yakapfuura tekinoroji sevhisi maitiro, takaona kuti kukanganiswa kwewelding kazhinji kwaiitika nekuda kwekushandisa zvisina kunaka kwemanozzles. Kusarudza iyo yakakodzera nozzle zvinhu, saizi uye mhando inogona kubatsira kuderedza nguva, yakaderera mutengo uye kuvandudza weld mhando uye kugadzirwa.
Basa remuromo ndere kutungamira gasi rinodzivirira kune dziva rakanyungudutswa uye kudzivirira dziva rakanyungudutswa kubva pakusvibiswa. Kusarudza muromo kunogona kuve nechokwadi chekuti gasi rine mwero wakakodzera wekuyerera inopinda mudziva rakanyungudutswa rakanyungudutswa. Kana iyo nozzle yakakodzera isina kusarudzwa, iyo weldment inogona kuve nematambudziko akati wandei kusanganisira yakawandisa spatter uye porosity, izvo zvinogona kupedzisira zvakonzera kuderera nekuda kwekugadzirisa zvakare. Saka kuti ungasarudza sei muromo chaiwo wakakosha zvakanyanya. Izvi zvinotevera zvinounza akati wandei akajairwa nozzles uye zvakanakira nekuipira kwawo.
muromo wakatwasuka
#StraightNozzles
Manozzles akatwasuka ndiwo anonyanya kuzivikanwa mhando yemhuno. Zvakanakira ndezvokuti inoshandiswa zvakanyanya uye inogona kushandiswa kune akasiyana-siyana welding scenarios, uye gasi shielding effect iri nani; chakashata ndechekuti nekuda kwegobvu repamberi remuromo, haigone kupinda mukati memukati kana groove yakamanikana, uye kureba kwetsvimbo-kunze kwewaya yewelding kuchaita kuti arc isagadzikana uye inokanganisa gasi. Panguva imwecheteyo, iyo yekumberi inovhara mutsara wekuona ichakanganisawo kucherechedzwa kwechidziva chakanyungudutswa uye arc panguva yewelding.
#ConeNozzle
Conical nozzles anowanzo shandiswa mune nhete gap groove welding. Kumucheto kwepamberi kune conical. Kubatsira kwaro ndekwekuti kumucheto kwepamberi kudiki, kunogona kupinda mukati memugero wakamanikana, uye zviri nyore kuona chimiro chedziva rakanyungudutswa uye arc; iyo yakashata ndeyokuti dhayamita yekunze idiki, iyo inokanganisa kuyerera kwegesi. Kuti uchengetedze mhando, maburi emhepo anogona kugadzirwa panguva yekushongedza, uye spatter panguva yewelding inogona kuvharira muromo, uye iyo yekutsiva frequency ichawedzera panguva yenguva refu welding, izvo zvichawedzera mutengo.
Kubva pamuromo kusvika pakubata zano
Hukama huri pakati pemhuno uye yekubata tipi ine mhedzisiro yakakosha pamhando ye weld. Iyo yekubata tipi inogona kuderera kupfuura muromo kana yakakwirira kupfuura muromo. Iyo yekubata tipi yakaderera pane muromo inogona kupa nani gasi kudzivirira kunaka, asi panguva imwe chete iyo inopfupisa kureba-kubuda kwewaya yewelding, zvichiita kuti zviome kuti mwenje wewelding upinde mugero. Sezvineiwo, muromo wekubata wakakwira kupfuura muromo uri nani kuti usvike kunzvimbo inorambidzwa kana bevel, asi mhando yekudzivirira gasi ichave yakashata.
Naizvozvo, welding opareta anofanirwa kusarudza imwe yakanyatsokodzera nozzle mushure mekuyera zvakanakira nekuipira.
