Site na mmepe ngwa ngwa nke ụlọ ọrụ petrochemical, ejirila ihe igwe anaghị agba nchara mee ihe n'ọtụtụ ebe, bụ nke tinyekwara ihe dị elu chọrọ maka ịgbado ọkụ nke ọkpọkọ na efere.Usoro ịgbado ọkụ igwe anaghị agba nchara gara aga ejirila nke nta nke nta kpochapụ, a na-ejikwa argon arc welding maka ịgbado ọkụ.
Argon arc welding primer dị ọcha yana ngwa ngwa karịa ngwa ịgbado ọkụ.N'otu oge ahụ, enwere nsogbu ụfọdụ.
N'oge usoro ịgbado ọkụ, ebe ọ bụ na azụ nke igwe anaghị agba nchara argon arc welding base na-adị mfe oxidized ma na-akpata ntụpọ, azụ nchedo ihe ga-eme ka iji hụ na n'ibu Njirimara na corrosion iguzogide weld.Ya mere, a ghaghị iwere nchebe dị irè mgbe ị na-agbado igwe anaghị agba nchara.
Taa, anyị na-ewebata ọtụtụ ụzọ nchebe azụ igwe anaghị agba nchara:
01
Ụzọ Nchekwa Argon azụ
Enwere ike kewaa gas nchebe nke a na-ejikarị gaa na nchebe argon gas dị mfe na nchebe gas agwakọta.Akụkụ ụfọdụ nke argon-nitrogen agwakọta gas na-enyere aka ịgbado ọkụ igwe anaghị agba nchara austenitic.A naghị eji ụfọdụ gas eme ihe n'ihi nnukwu ọnụ ahịa ha.
Nchedo usoro ndochi Argon bụ usoro nchebe azụ azụ nke ọdịnala, nke nwere njirimara nke nchebe azụ ka mma, dị mfe ịmụta, ịdị ọcha dị elu, na ọnụ ọgụgụ dị elu.E kewara ya na mkpuchi mkpuchi mkpuchi argon, usoro nchekwa nchekwa argon mpaghara, ndochi nke nkwonkwo ịgbado ọkụ, usoro nchebe argon, wdg.
1. mkpuchi mkpuchi jupụtara na usoro nchebe argon
A na-ejikarị usoro a eme ihe na igwe anaghị agba nchara nke efere na nnukwu dayameta ọkpọkọ.A na-ejikọta ihe mkpuchi nchebe na ọkpọkọ ígwè na argon gas hose.A na-emeghe valve argon gas iji mejupụta mkpuchi nchebe na gas argon.
A na-achọrọ onye ọzọ ijide ọkpọkọ ígwè dị ka aka ka ihe mkpuchi nchebe na-adaba na ọdọ mmiri a wụrụ awụ na azụ na mmekọrịta ya na ịgbado ọkụ nke efere ma ọ bụ ọkpọkọ.
N'ụzọ dị otú a, a na-echebe akụkụ azụ nke ọma, a na-etinyekwa ihe nchebe ahụ.The argon gas adịghị mkpa ka a meghere nke ukwuu, na argon gas na-ala n'iyi obere.
2. Nchedo na-ejuputa argon mpaghara
Ọ dị mfe iji nchebe mpaghara maka pipeline nwere obere oghere mpaghara yana akụkụ dị mkpụmkpụ.
Usoro: Mechie nkwonkwo ịgbado ọkụ nke ọkpọkọ na teepu (iji gbochie ikuku ikuku).Mechie njedebe abụọ nke ọkpọkọ na sponge, rubber, shei akwụkwọ, wdg. Tinye eriri argon site na otu nsọtụ wee jupụta argon.A na-emechi njedebe nke ọzọ nke ọkpọkọ.Gwuo obere oghere (ọ dịghị mkpa maka sponge), nke ga-eme ka nkwonkwo ịgbado ọkụ ikpeazụ dịkwuo mfe ma ghara ime ka ọkpụkpụ n'ihi oke nrụgide dị n'ime.
N'oge ịgbado ọkụ, iji gbochie nnukwu ego nke argon gas na-esi na weld seam, weld sealing teepu kwesịrị adọka na welded na ngalaba, nke nwere ike ibelata ọzọ ọnwụ nke argon gas na n'ụzọ dị irè na-echebe weld onuete.Atụmatụ na-ala n'iyi, argon chaja na-adị nwayọọ, ọnụ ahịa dị oke elu, wdg.
3 .Direct argon na-ejuputa usoro nchebe maka nkwonkwo ịgbado ọkụ
Maka pipeline nke dị ogologo ma nwee nnukwu dayameta dị ntakịrị, imeju argon mpaghara na-efunahụ ya, a pụghị ijide n'aka àgwà ahụ, na ụgwọ ọrụ ahụ dị oke elu.Iji chekwaa ego, enwere ike iji usoro ndochi argon kpọmkwem na nkwonkwo welded.
Ụzọ nke ime plọg na abụọ nke weld onuete
Hazie sponge ahụ n'ime plọg nwere dayameta dịtụ ukwuu maka ọkpọkọ wee jikọọ iberibe sponge abụọ ahụ na waya n'ebe dị anya nke 300-400mm iji mepụta plọg okpukpu abụọ.A na-ejikọta otu njedebe nke plọg na eriri igwe ogologo ogologo.
Mgbe ị na-ejikọta, tinye plọg na 150-200mm n'akụkụ abụọ nke weld ka a ga-agbado.Ogologo eriri igwe dị n'otu njedebe kwesịrị ịdị ogologo karịa ogologo ọkpọkọ n'otu njedebe nke weld ma kpughee njedebe ọkpọkọ.Otu njedebe nke obere ọkpọkọ ígwè kwesịrị ịgbatị na njedebe nke ọzọ ga-ejikọta ya na eriri argon.Fanye njedebe gbawara agbawa n'ime weld kwekọrịtara ma jupụta argon.Ntuziaka ntinye kachasị mma bụ akụkụ kachasị elu, nke mere na tupu nkwonkwo ikpeazụ nke ala weld, enwere ike ịdọpụ obere tube ma gbanye ya site na gas fọdụrụnụ na ọkpọkọ.Mgbe ịgbado ọkụ, jiri waya dọpụta plọg ahụ.
Usoro nchebe akwụkwọ soluble mmiri
Tupu mgbakọ, tinye akwụkwọ na-agbaze mmiri na 150-200mm n'akụkụ abụọ nke nkwonkwo ịgbado ọkụ dị ka akara.Mgbe itinye n'usoro, jiri otu usoro ịgbado ọkụ nwere ike ịfụ ọkụ dị ka sponge.Mgbe a na-anwale pipeline maka nrụgide hydraulic, akwụkwọ mmiri na-edozi mmiri ga-agbaze ma wepụ ya na mmiri.
4. Argon gas nchebe ikpe
Enwere ike ikpe mmetụta nchebe nke gas argon dị ka agba nke weld dị n'ime, ka onye ọrụ ahụ nwee ike ịhazigharị gas argon dị ka agba iji nweta mmetụta nchebe kachasị mma.Agba ndị ahụ na-acha ọcha na ọla edo, na isi awọ na ojii kacha njọ.
5. Akpachara anya maka nchekwa igwe anaghị agba nchara
(1) Tupu ịgbado ọkụ argon arc, a ga-echebe azụ nke weldment site na-ejuputa ya na argon tupu oge eruo.Ọnụego mgbaba kwesịrị ibu ibu.Mgbe ikuku gbasasịrị, ọbịbịa ahụ ga-eji nwayọọ nwayọọ belata.N'oge usoro ịgbado ọkụ, ọkpọkọ kwesịrị jupụta argon mgbe niile.Enwere ike iwepụ eriri argon naanị mgbe emechara ịgbado ọkụ ka weld wee chebe ya nke ọma.
Tụkwasị na nke ahụ, ekwesịrị ịkwụ ụgwọ nlebara anya pụrụ iche n'eziokwu ahụ bụ na a ga-arụ ọrụ ịgbado ọkụ naanị mgbe ikuku gwụchara, ma ọ bụghị ya, a ga-emetụta mmetụta nchebe nke njuputa argon.
(2) Ọnụego ikuku argon kwesịrị ekwesị.Ọ bụrụ na ọnụego na-erugharị dị ntakịrị, nchebe adịghị mma, na azụ nke weld na-adị mfe oxidized;ọ bụrụ na ọnụ ọgụgụ na-asọ asọ dị ukwuu, a ga-eme ka ntụpọ dị ka concavity nke mgbọrọgwụ nke weld, na-emetụta àgwà ịgbado ọkụ.
(3) Ekwesịrị itinye ntinye gas argon dị ka o kwere mee na mpaghara mechiri emechi, a ga-etinyekwa oghere ikuku ikuku dị ntakịrị elu na mpaghara ọkpọkọ mechiri emechi.N'ihi na argon dị arọ karịa ikuku, imeju argon site na ọnọdụ dị ala nwere ike hụ na ntinye uche dị elu, na nchebe nchebe nke nsị argon ga-aka mma.
(4) Iji belata ọnwụ nke argon gas na ọkpọkọ site na ọdịiche dị n'etiti nkwonkwo, nke na-emetụta mmetụta nchebe ma na-abawanye ọnụ ahịa, a pụrụ itinye teepu n'akụkụ oghere dị n'etiti nkwonkwo ịgbado ọkụ tupu ịgbado ọkụ, na-ahapụ naanị ogologo oge. n'ihi na otu na-aga n'ihu ịgbado ọkụ site welder, na iwepu teepu mgbe ịgbado ọkụ.

Usoro nchedo waya ịgbado ọkụ nke onwe
Igwe ịgbado ọkụ na-echebe onwe ya na azụ bụ waya ịgbado ọkụ na mkpuchi.N'oge ịgbado ọkụ, mkpuchi nchebe ya ga-ekere òkè na nchebe zuru oke nke ihu na azụ nke ọdọ mmiri a wụrụ awụ, na-akpụ akwa mkpuchi nchebe iji gbochie azụ nke weld bead ka ọ ghara ịdị na-ekpo ọkụ.Igwe nchekwa a ga-adapụ ozugbo ka ọ dị jụụ, a ga-ehichapụkwa ma nwalee n'oge ule nrụgide.a ga-ekpochapụ.
The ojiji usoro nke ụdị ịgbado ọkụ waya bụ isi ihe dị ka nke nkịtị argon arc ịgbado ọkụ siri ike isi waya, na arụmọrụ nke weld metal nwere ike izute chọrọ.
A naghị egbochi waya ịgbado ọkụ nke na-echebe onwe ya site na ọnọdụ ịgbado ọkụ dị iche iche, na-eme nkwadebe ịgbado ọkụ ngwa ngwa na mfe.Otú ọ dị, n'ihi mkpuchi dị n'elu waya ịgbado ọkụ, a ga-enwe ahụ erughị ala mgbe ndị ọrụ ịgbado ọkụ na-arụ ọrụ ya.
N'ihi enweghị nkwekọrịta na usoro ịgbado ọkụ adịghị mma maka waya ịgbado ọkụ mkpuchi, ntụpọ dị ka concavities mgbe ụfọdụ na-eme.Ya mere, e nwere ụfọdụ chọrọ maka ịgbado ọkụ pesonel si arụ ọrụ nkà na usoro.A na-eji waya mkpuchi onwe ya kacha mma maka primers n'ihi nnukwu ọnụ ahịa ya.
Na mgbakwunye, e nwere ọtụtụ ụdị nke waya ịgbado ọkụ na-echebe onwe ya na ahịa ịhọrọ site na, na ntinye ha dịkwa iche.
