E7028 electrode yekunamira

Tsananguro pfupi:

Electrode yesimbi yekabhoni yakaputirwa nehydrogen-potassium-iron-powder yakaderera.

AWS A5.1 E7028 Tsvimbo yekushongedzas

Welding electorde AWS A5.1 E7028 i electrode yesimbi ine hydrogen-potassium-iron-powder coated low-hydrogen-potassium-iron. Upfu hwesimbi huri mu coating hunowedzera deposit rate kusvika 180%. Hune kushandiswa kwakanaka kwazvo kunoita kuti ive ne stable arc, low-spratter, kubvisa slag kuri nyore uye kunoita all-position welding. Simbi yakachengetwa ine hunhu hwakanaka hwemakanika hunopa kusimba kwakanaka kwazvo pakupisa kwakaderera.

Kushandiswa

AWS A5.1 E7028 inoshandiswa mukusanganisa mafirita akatsetseka uye akatsetseka muzvivakwa zvakagadzirwa nesimbi yekabhoni uye simbi isina alloy yakawanda senge 16Mn, 09Mn2Si uye A, B, D, E simbi dzinoshandiswa mukuvaka ngarava.

Zvinyorwa:

1. Electrode inofanira kupisa patembiricha ye350°C kweawa imwe chete. Pisa tsvimbo pese painoshandiswa.

2. Tsvina yakaita sengura, mavara emafuta uye hunyoro zvinofanirwa kubviswa pabasa.

3. Mutsetse mupfupi unodiwa pakupinza simbi. Nzira yakamanikana yekupinza simbi ndiyo inofarirwa.

Kuchengeta nekubika E7028 Welding Electrode

Sezvo iri electrode ine hydrogen shoma, E7016 inodakubheka/kuomesausati washandisa. Tembiricha inokurudzirwa yekuomesa kana yekubikira yeE7028 rod sezvakataurwa naAWS A5.1, Tafura 1.3 ndeye 500-800°F (260-425°C) kwemaawa 1-2.

Electrode yakabikwa kana yakaomeswa inofanira kuchengetwa muovheni inotakurika patembiricha ye50-250°F (30-140°C) panguva yekushandiswa. Electrode dzisina kushandiswa dzinofanira kudzoserwa mumaovheni asingachinji.
