Zvinhu zveweldkuremara

(1) Zvinhu zvezvinhu:

Izvo zvinodaidzwa kuti material factor inoreva welding base simbi uye welding zvinhu zvinoshandiswa, zvakaita sewaya, tsvimbo, flux, uye gasi rekudzivirira nezvimwe zvakadaro.Zvese zvezvishandiso izvi zvinosanganisirwa mune welding puddle kana physico-kemikari maitiro eiyo fusion zone, uko hwaro hwezvinhu zvekuita kwakanaka kwechigadzirwa pachacho, mbiri-zone kupisa mumvuri kurwisa kwakasimba maitiro.Pamusoro pekuumbwa uye zvivakwa zve weld simbi zvakare chinhu chakakosha mune welding zvinhu zvinoshandiswa zvakajeka.Zvibereko zvakanaka uye base metal welding zvinhu zvisingaenderane, kwete chete zvinogona kukonzera kukanganisa kwakasiyana-siyana munzvimbo ye weld kune mitsetse, pores, nezvimwewo, uye inogonawo kuwanikwa kubva kune embrittlement, corrosion-resistant zvivakwa kupfava kana kuchinja.Naizvozvo, kuitira kuti ive nechokwadi zvakanaka weld majoini anofanira kutarisisa zvizere zvinhu zvinhu.

(2) Tekinoroji zvinhu:

Kudzidzira kwakawanda kwakaratidza kuti iyo imwe mhando yesimbi yepasi mune dzakasiyana nzira dzewelding uye maitiro ekuyera mamiriro, iyo welding mhando inoratidza musiyano mukuru.Inokanganisa kunaka kweiyo welding nzira yewelding main inogoneka mumativi maviri: Chekutanga, hunhu hwewelding heat sosi, inova simba density, yakanyanya kupisa tembiricha, chiyero chesimba, nezvimwewo, vanogona kushandura maparameter eiyo welding. thermal cycle yakananga, senge mutsara wesimba, yakakwirira-yekupisa yekugara nguva, iyo chikamu chekuchinja tembiricha yehuwandu hwekutonhora.Izvi zvechokwadi zvichakanganisa microstructure uye zvivakwa zvemajoini;chechipiri kune dziva uye nzvimbo iri padyo yekudzivirira, senge slag dziviriro, gasi, gasi - slag jiviriro yekubatana kana welding mune vacuum, izvo zvinokanganisa maitiro ekushongedza simbi.Zviripachena, iyo nzira yewelding yekudziya uye metallurgical maitiro emhando uye kuita zvinozobatanidza majoini zvine simba.
