The chinhu chakakombama iri: Description uye unhu

The chinhu chakakombama chinhu riemukaari kukangamwirwa kunoitika pakati electrodes maviri kana electrode uye workpiece uye izvo rinobvumira kuti pave remubatanidzwa zviviri kana kupfuura zvidimbu Welding.

The Welding chinhu chakakombama zvichienderana zvakatipoteredza nayo kunoitika, rakakamurwa mapoka akawanda. Zvingava akazaruka, akavharwa, uye kudzivirirwa gasi.

Open chinhu chakakombama runoyerera panze kuburikidza ionization iri combustion pakati nezvimedu, uyewo nokuda simbi mhute uye welded zvikamu electrode zvinhu. Closed chinhu chakakombama, akavapindurawo, magetsi anyatsofukidzwa. Izvi zvinobvumira kushandura Kuronga gaseous svikiro iri combustion uye kudzivirira simbi kubva oxidation blanks. The chinhu chakakombama Saka Rwako kuburikidza simbi mhute ions uye ane zvinoyerera chirungiso. The chinhu chakakombama, riri yokunotsva kudzivirirwa gasi runoyerera napakati gasi ions uye simbi vapor. Izvi zvinobatsira kudzivirira oxidation nezvikamu, saka kuwedzera rakavimbika akaumba akakura.

The chinhu chakakombama kwakasiyana kubudikidza yezvakaita kusvitsa ano - kugara kana shanduka - uye ya combustion - kupomba kana mira. Mukuwedzera, chinhu chakakombama inogona kururamiswa kana neizvi polarity.

Maererano mhando electrode kushandiswa kusiyanisa non-consumable uye kunyunguduka. Kushandiswa mumwe kana mumwe electrode anoenderana zvainyanya akadzadzwa chakanamwa nomoto machine. The chinhu chakakombama kuti unovapo kana uchishandisa dzisiri consumable electrode, sezvo zita rinoreva, hazvirevi deform nayo. Kana Welding consumable electrode ano chinhu chakakombama inonyunguduka zvokunyama uye welded kusvikira pakutanga chimedu.

The chinhu chakakombama pakakoromoka inogona kukamurwa zvitatu mamirire nharaunda: precathode, pre-anode, uye chinhu chakakombama mugodhi. In ichi rokupedzisira chidimbu, kureva chinhu chakakombama hunde une kunonyanyisa kureba Zvisinei, zvechadenga chinhu chakakombama, uye mukana parinowanika akatsunga okoloelektrodnymi kumatunhu.

Kazhinji, zvainyanya akadzadzwa yemagetsi chinhu chakakombama inogona mumapoka anotevera zvawanyora:

1. Kureba chinhu chakakombama. Izvi zvinoreva zvachose chinhambwe pakati cathode uye anode nharaunda, uye arc Upfu.

2. voltage yacho chinhu chakakombama. Ndicho kuwanda ari voltage anodonhedza nechimwe munzvimbo: hunde, pedyo cathode uye anode. The Kuchinja voltage okoloelektrodnyh nzvimbo iri kupfuura munharaunda yasara.

3. Temperature. The chinhu chakakombama zvichienderana Kuronga gaseous svikiro, kuti electrode zvinhu uye kuitika arambe achirema inogona kusvika tembiricha anosvika zviuru 12 madhigirii Kelvin. Zvisinei, nenhongonya izvi hazvisi akaronga mhiri ndege yacho kuguma electrode. Nekuti kunyange kurapwa pamusoro acho ari conductive chikamu ane anorovera siyana uye anorovera, nemhaka iyo pane mamwe matomu, izvo akaona somunhu. Chokwadi, zvikurukuru pakuti tembiricha iri riemukaari ezvinhu umo iri kutsva, uyewo pari yawapihwa parameters. Somuenzaniso, kana tiri kuwedzera uwandu ano kuti, maererano, kuwedzera tembiricha ukoshi.

Pakupedzisira, kuitika-voltage unhu kana ano-voltage unhu. Zvinomirira voltage kutsamira pamusoro urefu uye kwakakura matsva.
