MMA: unhu uye kupatsanura

Manual chinhu chakakombama nomoto inonzi nekuti zvose zvaidiwa zviito nyanzvi ndiri weredha manually kudaro. Ndiye anokonzera anoita uye arambe achirarama chinhu chakakombama, kuti chinhu chakakombama kwebasa kubatana pamusoro zvaida chinguva, kugoverwa electrodes itsva pane kushandiswa. Weld unhu kunoenderana unyanzvi ndiri weredha. Vanofanira kukurumidza vesa kuti chinhu chakakombama, kuti kunyatsotevera kuongorora kuti kureba kwayo kwakanga zvakafanana, uyewo kubudisa yunifomu nomoto pakati migove miviri.

MMA ane imwe kupatsanura. Somuenzaniso, maererano neuwandu electrodes zvinoshandiswa weld kusiyanisa imwe kana mbiri electrodes, uye multi-electrode. Kune zvitatu-danho uye chete-danho chinhu chakakombama, chimiro ano angava AC kana DC.

Parizvino kupararira nomoto pamwe rakatumbuka kana zvakananga ichangobuda vachishandisa consumable electrode. Chokwadi, kune vakawanda dzakasiyana kubatanidza nhindi Welding. Somuenzaniso, kuti aumbe mhando dzakasiyana mapfundo (flanged kumicheto). Kuwedzera negoho ashandise electrodes ari danda, uye nomoto pakati alloys siyana uye non-ferrous simbi dziri tungsten electrodes.

MMA ane chaizvo mukugadzira kwacho. Kana Welding electrodes siyana anoshandiswa, izvo zvinogona consumable uye nonconsumable. Aimbova anogona kuitwa waya chaiwo unhani. spraying akadaro anodiwa yakakwirira mwero kugadzikana magetsi chinhu chakakombama zvinopa resimbi pamusoro marara uye oxides izvo achengetedze weld mudziva kubva kudyidzana pamwe zvakatipoteredza, uye kudzivirira arc nzvimbo nekuita chete mhepo.

Manual TIG nomoto kunogona kuitwa panguva dzakasiyana-siyana ambient ezvinhu uye magasi akasiyana-siyana. Somuenzaniso, Chinyorwa argon-riemukaari nomoto (mumamiriro ezvinhu ose argon), nomoto mumhepo uye t. D.

Maererano GOST 9466-75, ivo electrodes akakamurwa marudzi anoverengeka.

1. By kugadzwa:

• uye kabhoni shoma-chiwanikwa STRUCTURAL steels;
• simbi alloys;
• kupisa nemishonga chiwanikwa simbi;
• soro-chiwanikwa STRUCTURAL steels.

2. Maererano mhando uye muchiso:

• mureza;
• tsika.

3. Sezvinoratidzwa pakukora ari sprayed unhani:

• dzakaonda;
• avhareji;
• makobvu;
• kunyanya gobvu.

4. By bemhapemha mhando electrode:

• asidhi;
• rutile;
• cellulose;
• yokunamisa upfu simbi.

5. bvumidzwa spatial nzvimbo electrodes:

• chero mbuva;
• chero, kunze kutwasuka Chinyorwa nomoto;
• nokuti rezasi chinjikira uye pamusoro wehunyambiri ndege;
• nokuti pasi "muchikepe."

6. polarity chakanamwa nomoto pari kushandiswa:

• zvakananga;
• harungashandurwi;
• chero.

7. By hunhu chakanamwa nomoto kuitika:

• zvachose;
• AC.

MMA kunoratidza kuti simbi iyo welded electrodes, anofanira kuva makemikari anoumba zvakafanana zvawaitaura. The zvemaziso zvechadenga zvichizoita weld uye weld simbi chinofanira kuiswa zvinoenderana GOST 9467-75.
