18 Maitiro Ekushanda eArgon Arc Welding!

2024-08-07

Argon arc welding inofanira kushandiswa nemunhu akazvipira pane switch.
Tarisa uone kana midziyo nematurusi zviri muchimiro chakanaka usati washanda.
Tarisa uone kana iyo welding magetsi ekupa uye control system ine waya dzekudzika, uye wedzera mafuta ekuzora kune chikamu chekufambisa. Iko kutenderera kunofanira kunge kwakajairika, uye argon uye matsime emvura anofanira kunge asina kuvharwa. Kana paine kudonha kwemvura, zivisa kugadzirisa nekukurumidza.
Tarisa kana pfuti yewelding iri kushanda nemazvo uye kana waya yepasi yakavimbika.
Tarisa uone kana iyo yakakwira-frequency arc ignition system uye welding system yakajairika, ingave waya uye tambo majoini akavimbika, uye kune otomatiki waya argon arc welding, tarisawo kana iyo yekugadziridza nzira uye waya yekudyisa michina.
Sarudza polarity yakavakirwa pachinhu cheiyo workpiece, batanidza welding wedunhu, kazhinji shandisa DC yakanaka yekubatanidza yemidziyo, uye shandisa reverse yekubatanidza kana AC magetsi ealuminium uye aruminiyamu alloys.
Tarisa kana iyo welding groove inokodzera, uye hapafanirwe kuve nemafuta mavara, ngura, nezvimwe pane groove pamusoro. Mafuta uye ngura zvinofanira kubviswa mukati me 200mm kumativi ose e weld.
Kune avo vanoshandisa molds, kuvimbika kwavo kunofanira kuongororwa, uye kune zvikamu zvakashongedzwa zvinoda kupiswa, preheating michina uye tembiricha yekuyera zviridzwa zvinofanirawo kuongororwa.
Iyo argon arc welding control bhatani haifanirwe kunge iri kure nearc, kuitira kuti inogona kudzimwa chero nguva kana ikasashanda.
Izvo zvinodikanwa kugara uchitarisa kune kuvuza kana uchishandisa yakakwira-frequency arc ignition.
Muchiitiko chekukundikana kwemidziyo, simba rinofanira kugurwa kuti rigadziriswe, uye vashandi havabvumirwi kugadzirisa pachavo.
Hazvibvumirwi kushama kana kuzarura zvimwe zvikamu pedyo nearc, uye kusvuta kana kudya hazvibvumirwi pedyo nearc kudzivirira ozone uye utsi kubva pakuputirwa mumuviri.
Paunenge uchikuya thorium tungsten electrodes, zvinodikanwa kupfeka masiki uye magurovhosi, uye kutevera maitiro ekushanda emuchina wekukuya. Zvakanakisisa kushandisa cerium tungsten electrodes (ine yakaderera mwaranzi mwero). Muchina wekukuya vhiri unofanirwa kunge uine mudziyo wekufema.
Vashandi vanofanira kupfeka static dust masks nguva dzose. Edza kuderedza nguva yemagetsi e-high-frequency panguva yekushanda. Kuenderera mberi kwebasa hakufaniri kudarika maawa matanhatu.
Iyo argon arc welding nzvimbo yebasa inofanirwa kuve nekutenderera kwemhepo. Ventilation uye detoxification midziyo inofanira kushandiswa panguva yebasa. Kana mudziyo wekufemesa ukatadza, unofanirwa kumira kushanda.
Masilinda eArgon haafanire kurohwa kana kupwanywa, uye anofanirwa kuiswa akati twasa nebhuraketi uye achengetedzwe kanenge 3 metres kubva pamoto wakavhurika.
Paunenge uchiita argon arc welding mukati memudziyo, maski yechiso yakasarudzika inofanirwa kupfekwa kuderedza inhalation yehutsi hunokuvadza. Panofanira kuva nemumwe munhu ari kunze kwegaba kuti atarise nekushandira pamwe.
Thorium tungsten tsvimbo dzinofanirwa kuchengetwa mumabhokisi emutobvu kudzivirira kukuvadzwa kunokonzerwa neakanyanya radioactive dose inodarika mitemo yekuchengetedza kana nhamba huru yethorium tungsten tsvimbo dzakanangana pamwe chete.
