Iyo Inoputika Nzira Yekudzivirira Gasi

Parizvino, kune nzira mbiri huru dzekuputira gasi rekudzivirira: imwe iparaxial side-blowing gasi rinodzivirira, sezvinoratidzwa mumufananidzo 1; Imwe icoaxial kudzivirira gasi.Sarudzo chaiyo yemaitiro maviri ekuputira inofungidzirwa mune zvakawanda.Kazhinji, zvinokurudzirwa kushandisa rutivi rwekuvhuvhuta kudzivirira gasi

paraxial inovhuvhuta inodzivirira gasi

coaxial inovhuvhuta inodzivirira gasi

Kutanga, zvinoda kujeka kuti iyo inonzi weld "oxidized" inongova zita rinowanzozivikanwa.Nechepfungwa, inoreva maitiro emakemikari pakati peweld uye zvinokuvadza zvinongedzo mumhepo, izvo zvinotungamira mukuipa kwemhando yeweld.Zvinowanzoitika kuti weld metal iite pamwe neokisijeni, nitrogen uye hydrogen mumhepo pane imwe tembiricha.

Kudzivirira weld kubva ku "oxidized" ndiko kuderedza kana kudzivirira kusangana kwezvinhu zvinokuvadza zvakadaro nesimbi ye weld mune yakanyanya tembiricha.Iyi yakakwirira tembiricha mamiriro haisi chete yakanyungudutswa dziva simbi, asi nguva yose muitiro kubva panguva apo weld simbi inonyungudutswa kuti solidification dziva simbi uye tembiricha yayo kunoderedzwa kuti imwe tembiricha pazasi.

Semuenzaniso, titanium alloy welding, kana tembiricha iri pamusoro pe300 ℃ inogona kukurumidza kutora hydrogen, inopfuura 450 ℃ inogona kukurumidza kusveta okisijeni, kupfuura 600 ℃ inogona kukurumidza kutora nitrogen, saka titanium alloy welding seam mushure mekusimba uye kuderedza tembiricha kusvika 300 ℃. pazasi nhanho iyi inofanirwa kuve inoshanda yekudzivirira maitiro, zvikasadaro ichave "oxidized".

Kubva pane tsananguro iri pamusoro haina kuoma kunzwisisa, kuchengetedzwa kwegasi rinofuridza hakungodi panguva yakakodzera kuchengetedza weld yakanyungudutswa dziva, zvakare inoda kunge yakashongedzerwa ingori nechando nzvimbo yedziviriro, saka kazhinji tora paraxial inoratidzwa mumufananidzo 1 side inodzivirira. gasi, nekuti nzira iyi ine chekuita nenzira dzekudzivirira dziviriro yenzira yekudzivirira yecoaxial yenhamba 2 yakawedzera kuwanda,Kunyanya iyo weld yakangoomeswa nzvimbo ine dziviriro iri nani.

Paraxial side inovhuvhuta yeinjiniya maapplication, hazvisi zvese zvigadzirwa zvinogona kushandisa nzira yedivi shaft yekufuridza gasi yekudzivirira, kune zvimwe zvigadzirwa, inogona chete kushandisa coaxial yekudzivirira gasi, chaiyo inodiwa kubva kune chigadzirwa chimiro uye fomu yekubatana yakanangwa sarudzo.

1. Sight welds

Sezvinoratidzwa muMufananidzo 3, chimiro cheweld chechigadzirwa chakatwasuka, uye chimiro chejoinhi chinogona kunge chiri chebutt joint, lap joint, negative corner joint kana overlapping welding joint.Kune rudzi urwu rwechigadzirwa, zviri nani kutora rutivi rweparutivi rwunofuridza nzira yekudzivirira gasi sezvakaratidzwa mumufananidzo 1.

2. Flat yakavharwa graphic weld

Sezvinoratidzwa muMufananidzo 4, iyo weld chimiro chechigadzirwa indege circumferential chimiro, ndege multilateral chimiro, ndege yakawanda-segment mutsara chimiro uye mamwe akavharika maumbirwo.Iyo yejoint form inogona kuve butt joint, lap joint, overlapping welding zvichingodaro.Kune rudzi urwu rwechigadzirwa, zviri nani kutora iyo coaxial inodzivirira gasi modhi inoratidzwa muMufananidzo 2.

Kusarudzwa kwegasi rinodzivirira kunokanganisa zvakananga kunaka kwewelding, kushanda nesimba uye mutengo wekugadzira, asi nekuda kwekusiyana kwezvinhu zvewelding, mune chaiyo welding process, kusarudzwa kwegasi rewelding yakanyanya kuoma, inoda kutariswa kwakadzama kwewelding zvinhu, welding nzira. , welding chinzvimbo, pamwe nezvinodiwa welding mhedzisiro, kuburikidza nemiedzo yewelding kusarudza iyo yakanyanya kufanirwa kune welding gasi, welding kuti uwane mhedzisiro iri nani.
