Nhau - Yooheart robhoti taurira zviziviso zvekudzivirira gasi welding

Gasi shielded welding inoreva nzira yewelding inodzivirirwa necarbon dioxide kana argon, pasina kushandisa welding waya. Iyo gasi shielded welding process inokodzera kukwenenzverwa kweakasiyana-siyana mahombe ekugadzira simbi mapurojekiti akadai seyepasi-kabhoni simbi uye yakaderera-alloy yakakwirira-simba simbi. Iyo ine yakakwira welding chigadzirwa, yakanaka crack resistance, diki welding deformation, uye yakakura deformation renji. Welding yemahwendefa akatetepa uye epakati uye makobvu ndiro zvinogoneka.

Yakasiyana-siyana welding nzira dzegasi dzakadzivirirwa welding

1. vertical up welding

Chinzvimbo chemwenje wekubatira chakanyanya kukosha kana welding vertically, uye tochi yewelding inofanirwa kunge iri perpendicular kune workpiece. Munguva ye-straight-line welding, weld bead inowanzoita convex, uye chitarisiko che weld bead chakashata uye chiri nyore kucheka.

Munguva ye-multi-layer welding, iyo yekumashure yekuzadza bead iri nyore kuve isingapindike kune welding, saka haiwanzo kushandiswa. Naizvozvo, iyo yakakwira vertical welding kazhinji inotenderera, uye nzira yekugezera idiki diki. Sezvo kupisa kwakanyanya panguva ino, iyo weld bead iri nyore kuputika, saka inofanira kusimuka nekukurumidza pasi pemamiriro euniform swing.

Kana gumbo rakakura rewelding richidikanwa, iyo crescent swinging nzira inofanira kushandiswa nekukurumidza pakati pe weld bead uye kugara zvishoma mativi ese kudzivirira under cut. Zvisinei, kungwarira kunofanirwa kutorwa kuti usashandise yakadzika yakakombamira crescent swing.

2. vertical down welding

Pakunyungudutswa kwakadzika, kuitira kuchengetedza dziva rakanyungudutswa, tochi yewelding inofanira kunanga nediagonally kudzika kudziva rakanyungudutswa uye kuchengetedza imwe kona. Iyo arc inofanirwa kugara yakanangana kumberi kwedziva rakanyungudutswa, kana zvisina kudaro, kana simbi yakanyunguduka ichiyerera ichienda kumberi kwearc, zviri nyore kukonzera mapundu emoto uye kusapinda. Pool metal yakasimudzwa.

Zvinokonzera porosity mune gasi shielded welding

Gasi rakaipa rinodzivirira

1. Unhu hwegasi muhumburumbira hwegesi hauna kunaka, uye hauna kuchena kweinopfuura 98%. Iine magasi anokuvadza akadai senitrogen, ayo anokonzera pores mushure mekuputika.

2. Iyo pombi yegesi kubva kune gasi cylinder kusvika kune welding torch haina kusimba, uye mhepo inounzwa kuti ibudise pores.

3. Mhepo turbulence inoburitsa stomata

a. Mhepo iri munzvimbo yekunze inovhiringidza mhepo inodzivirira yakatenderedza dziva rakanyungudutswa

b. Yakaderera gasi kuyerera kana splatter ichivhara muromo

c. Iko kona yetochi yewelding yakakura kwazvo kana tochi yekubatira iri kure zvakanyanya kubva kune workpiece

d. Iyo gasi shunt ceramic gidhi mhete ye torch nozzle yakakuvadzwa uye haina kubviswa kana kutsiviwa

4. Welding machine control air valve inovhura lag, inovhara kare, kana iri mukushaya kuonana nguva nenguva

Kukanganisa muwelding waya uye base simbi pachayo

1. Iyo yakasimba core welding wire ine ngura, ine mafuta, nezvimwe.

2. Hupfu hwemukati hwe flux-cored welding wire inonyorova, uye kunze kune ngura.

3. Kune pores musimbi yepasi pachayo, kana kune yakawanda kusvibiswa kwemafuta mukati, kana simbi yemhando yekuchinja inokonzerwa nekushandiswa kwenguva refu mumamiriro emakemikari, zvakadai semapiipi emakemikari, muchina wesimbi yakakandwa uye zvikamu zvesimbi.

4. Kune zvinosvibisa kana mvura inogadzira magasi anokuvadza munzvimbo yewelding, uye haina kucheneswa.

Zvisina musoro welding parameters

Kana iyo yemazuva ano uye yemagetsi configuration yakakura zvikuru, zviri nyore kuparadza kabhoni monoxide mu carbon monoxide mukupisa kwakanyanya uye yakakwirira ionization mamiriro apo kupisa kwekushisa kwakakura, uye carbon monoxide pores inogadzirwa apo weldment inotonhora nokukurumidza.

Mhinduro yemhinduro

1. Wedzera argon kana carbon dioxide yakasanganiswa gasi kuti uone kana carbon dioxide gasi haina kuchena, uye ona kana gasi rakasanganiswa rine simba rekudzivirira riri nani. Kana hongu, shandura gasi rekupa chikamu nemhando yakanaka.

2. Pasi pekuchengetedzwa kwegasi rakasanganiswa, kuchine pores kubvisa chinokonzera gasi, uye zvimwe zvikonzero zvinogona kuongororwa nemaziso.

3. Zvakanakisisa kuti usafuratira matambudziko esimbi yepasi uye welding wire pachayo.
