Ọla kọpa ịgbado ọkụ
Ụzọ nke ịgbado ọkụ ọla kọpa (nke a na-akpọkarị ụlọ ọrụ dị ọcha ọla kọpa) gụnyere gas ịgbado ọkụ, akwụkwọ ntuziaka carbon arc ịgbado ọkụ, ntuziaka arc ịgbado ọkụ na akwụkwọ ntuziaka argon arc ịgbado ọkụ, na nnukwu owuwu nwekwara ike ịbụ akpaghị aka ịgbado ọkụ.
1.The kasị eji ọla kọpa gas ịgbado ọkụ bụ nkwonkwo butt, na overlap nkwonkwo na T nkwonkwo kwesịrị iji dị ole na ole dị ka o kwere mee. Enwere ike iji ụdị waya ịgbado ọkụ abụọ maka ịgbado ọkụ gas. Otu bụ waya ịgbado ọkụ nwere ihe deoxygenation, dị ka wires 201 na 202; nke ọzọ bụ waya ọla kọpa n'ozuzu na mpempe akwụkwọ nke isi ihe, na onye ọrụ gas 301 na-eji dị ka mgbanwe. Ekwesịrị iji ọkụ na-anọpụ iche mee ihe mgbe a na-agbado ọla kọpa gas.
2.A na-eji mkpanaka ọla kọpa ọla kọpa ọla kọpa 107 maka ịgbado ọkụ akwụkwọ ntuziaka, na isi ịgbado ọkụ bụ ọla kọpa (T2, T3). Ekwesịrị ịsacha akụkụ nke ịgbado ọkụ tupu ịgbado ọkụ. Mgbe ọkpụrụkpụ nke weldment bụ ukwuu karịa 4 mm, preheating ga-preheated tupu ịgbado ọkụ, na preheating okpomọkụ bụ n'ozuzu gburugburu 400 ~ 500 ℃. Mgbe ịgbado ọkụ na ọla kọpa 107 mkpara ịgbado ọkụ, ike ọkọnọ ga-atụgharị site DC.
3.Short arcs kwesịrị iji mee ihe n'oge ịgbado ọkụ, na mkpara ịgbado ọkụ ekwesịghị ịmafe horizontally. Mkpanaka ịgbado ọkụ na-eme ka mmegharị nke ahịrị na-emegharị, nke nwere ike imeziwanye nhazi nke weld. Ogologo weld kwesịrị iji nke nta nke nta gbado ya. Ọsọ ịgbado ọkụ kwesịrị ịdị ngwa ngwa o kwere mee. N'oge ịgbado ọkụ multi-layer, slag n'etiti n'ígwé ga-ewepụ kpamkpam. Ekwesịrị ịme ịgbado ọkụ n'ebe ikuku dị mma iji gbochie nsị ọla kọpa. Mgbe ịgbado ọkụ gasịrị, jiri hama dị larịị ka ọ kpatụ weld ahụ iji wepụ nchekasị ma melite ogo weld ahụ.
4.Manual argon arc ịgbado ọkụ nke ọla kọpa. Mgbe akwụkwọ ntuziaka argon arc nke ọla kọpa, wires eji bụ waya 201 (ọkachamara ọla kọpa welding waya) na waya 202, na-ejikwa ọla kọpa waya, dị ka T2.
Tupu ịgbado ọkụ, na oxide film, mmanụ na ndị ọzọ unyi na ịgbado ọkụ n'ọnụ nke workpiece na elu nke waya ga-ehicha ya iji zere ntụpọ dị ka pores na slag inclusions. Ụzọ ihicha na-agụnye ihicha igwe na ihicha kemịkal. Mgbe ọkpụrụkpụ nke efere nkwonkwo butt na-erughị 3 mm, a naghị emeghe bevel ahụ; mgbe ọkpụrụkpụ efere dị 3 ruo 10 mm, a na-emeghe bevel nke nwere ụdị V, na akụkụ bevel bụ 60 ruo 70; mgbe ọkpụrụkpụ nke efere dị ukwuu karịa 10 mm, a na-emeghe bevel nke X, The bevel angle bụ 60 ~ 70; ka ịzenarị agbasaghị, a na-ahapụkarị akụkụ ndị na-adịghị mma. Dị ka efere efere na nha bevel si dị, a na-ahọrọ oghere mgbakọ nke nkwonkwo ụkwụ n'ime oke nke 0,5 ruo 1.5 mm.
Ọla kọpa argon arc ịgbado ọkụ na-ejikarị DC mma njikọ, ya bụ, tungsten electrode jikọọ na-adịghị mma electrode. Iji kpochapụ oghere ikuku ma hụ na njikọta a pụrụ ịdabere na ya na ntinye nke mgbọrọgwụ weld, ọ dị mkpa ịbawanye ọsọ ịgbado ọkụ, belata oriri argon, ma kpoo ọkụ ọkụ. Mgbe efere efere bụ ihe na-erughị 3 mm, preheating okpomọkụ bụ 150 ~ 300 ℃; mgbe efere ọkpụrụkpụ bụ ukwuu karịa 3 mm, preheating okpomọkụ bụ 350 ~ 500 ℃. Igwe ọkụ na-ekpo ọkụ ekwesịghị ịdị elu, ma ọ bụghị ya, a ga-ebelata ihe eji arụ ọrụ nke nkwonkwo welded.
E nwekwara ọla kọpa carbon arc ịgbado ọkụ, na electrodes eji maka carbon arc welding gụnyere carbon essence electrodes na graphite electrodes. Waya ịgbado ọkụ a na-eji ọla kọpa carbon arc ịgbado ọkụ bụ otu ihe ahụ dị ka mgbe ịgbado ọkụ gas. A pụkwara iji ihe mgbakwasị ụkwụ na-egbutu ibe, na fluxes nke ọla kọpa dị ka gas agent 301 nwere ike iji.
Mgbado ọkụ ọla
1.The ụzọ nke ọla ịgbado ọkụ gụnyere: gas ịgbado ọkụ, carbon arc ịgbado ọkụ, ntuziaka arc ịgbado ọkụ na argon arc ịgbado ọkụ. 1. Gas ịgbado ọkụ nke brass N'ihi na okpomọkụ nke gas ịgbado ọkụ ọkụ dị ala, na zinc evaporation na brass n'oge ịgbado ọkụ bụ ihe na-erughị mgbe a na-eji eletriki ịgbado ọkụ, otú gas ịgbado ọkụ bụ nke a na-ejikarị usoro na brass ịgbado ọkụ (na-ekele gị maka ịṅa ntị na Dingding Automatic Welding).
Waya ịgbado ọkụ nke a na-eji maka ịgbado ọkụ gas brass gụnyere: waya 221, waya 222 na waya 224. Waya ịgbado ọkụ ndị a nwere ihe ndị dị ka silicon, tin, iron, wdg, nke nwere ike igbochi ma belata evaporation na ọkụ nke zinc n'ime ọdọ mmiri a wụrụ awụ, ma dị mma iji hụ na weld ahụ. Ịrụ ọrụ ma gbochie oghere ikuku. Fluxes ndị a na-ejikarị na ọla ịgbado ọkụ gas gụnyere ntụ ntụ siri ike na flux gas. Mgbanwe gas nwere boric acid methyl abụba na methanol; Fluxes dị ka onye nnọchi anya gas 301.
2.Manual arc welding of brass Na mgbakwunye na ọla kọpa 227 na ọla kọpa 237, a pụkwara iji mkpanaka ịgbado ọkụ arụrụ n'ụlọ maka ịgbado ọla.
Mgbe ịgbado ọkụ brass arc, a ga-eji usoro njikọ dị mma na-enye ọkụ DC wee jikọọ mkpanaka ịgbado ọkụ na electrode na-adịghị mma. Ekwesịrị iji nlezianya hichaa elu nke weldment tupu ịgbado ọkụ. Oghere bevel ekwesịghị ịbụ ihe na-erughị 60 ~ 70o. Iji melite weld guzobe, na welded akụkụ kwesịrị preheated na 150 ~ 250 ℃. Ekwesịrị iji ịgbado ọkụ dị mkpụmkpụ n'oge a na-arụ ọrụ, na-enweghị mbugharị kwụ ọtọ ma ọ bụ na-aga n'ihu na azụ azụ, naanị mmegharị ahịrị ahịrị, na ịgbado ọkụ kwesịrị ịdị elu. A ga-ekpochasị akụkụ ndị agbado bras nke na-abanye na mgbasa ozi na-emebi emebi dị ka mmiri mmiri na amonia ka ịgbado ọkụ ga-ewepụ nrụgide ịgbado ọkụ.
3.Manual argon arc ịgbado ọkụ nke ọla. Manual argon arc welding of brass nwere ike iji ọkọlọtọ brass wires: waya 221, waya 222 na waya 224, na ihe ndị nwere otu ihe dị ka isi ihe nwekwara ike iji dị ka filler ihe.
Enwere ike ịme ịgbado ọkụ site na ozugbo ugbu a ma ọ bụ AC. Mgbe ị na-eji AC ịgbado ọkụ, evaporation nke zinc na-adị ọkụ karịa mgbe ejikọrọ ozugbo. Ọtụtụ mgbe, preheating adịghị mkpa tupu ịgbado ọkụ, na preheating bụ naanị mgbe ọkpụrụkpụ nke efere dịtụ ukwuu. Ọsọ ịgbado ọkụ kwesịrị ịdị ngwa ngwa o kwere mee. Mgbe ịgbado ọkụ, na welded akụkụ kwesịrị kpụ ọkụ n'ọnụ na 300 ~ 400 ℃ maka annealing iji kpochapụ ịgbado ọkụ nchegbu iji gbochie cracks na welded akụkụ n'oge ojiji.
4.Brass carbon arc welding Mgbe brass carbon arc welding, waya 221, waya 222, waya 224 na ndị ọzọ ịgbado ọkụ wires na-ahọrọ dị ka mejupụtara nke isi ihe. Ị nwekwara ike iji eriri ịgbado ọkụ ọla arụrụ n'ụlọ iji weld. Enwere ike iji onye na-ahụ maka gas 301 ma ọ bụ ihe ndị yiri ya dị ka mgbanwe na ịgbado ọkụ. Ekwesịrị ịgbado ọkụ ahụ obere arc iji belata evaporation zinc na mmebi ọkụ.
