1. Welding deformation akara usoro
(1) Mee nyocha ezi uche dị na ya na ngụkọ nke ihe owuwu ahụ, chọpụta nrụrụ ịgbado ọkụ na ebe nchekwa shrinkage, yana maka akụkụ ọnụ dị mgbagwoju anya, enwere ike ikpebi mgbado nchekwa nchekwa site na nnwale.
(2) Jikwaa mkpochapụ mgbakọ
Jikwaa nke ọma nzizi nhazi bevel na mkpochapụ mgbakọ, wee họrọ udi oghere kwesịrị ekwesị na usoro ịgbado ọkụ iji belata nrụrụ ịgbado ọkụ.
(3) Jiri etiti taya na-egbochi nrụrụ
Jikọta ọnụ na mgbakọ taya dị mkpa na ịgbado ọkụ, ihe ndozi ngwá ọrụ, nkwado na oke mbelata echekwabara.
(4) Mee mgbakọ n'ozuzu ya na iberibe
Maka ihe mgbagwoju anya, dị ka o kwere mee na ngọngọ, usoro ịgbado ọkụ n'ozuzu nke mmepụta.
Mgbado ọkụ-na-ibe:
(5) Symmetrical na edo ịgbado ọkụ
Ø Mgbe akwa akwa akwa akwa akwa akwa akwa akwa akwa, ọnụ ọgụgụ nke ntụgharị na-abawanye dịka nrụrụ ahụ si dị, a na-etinyekwa ịgbado ọkụ n'ụzọ dị nro, na mgbazi ọkụ na usoro ahụ na-adakọkwa.
Ø Mgbe nkesa weld nke akụrụngwa na-adabere na nkesa axisymmetric geometrically na-anọpụ iche nke akụrụngwa, ịgbado ọkụ nke akụrụngwa na-anabata ịgbado ọkụ n'otu n'otu iji mebie nrụrụ n'ozuzu nke akụrụngwa site na iji ụkpụrụ nke symmetry.
Ø A haziri welds abụọ a na-ahazi dịka ụgbọ elu na-anọpụ iche axis symmetry bụ ndị na-ahụ maka ibe ha n'otu ntụziaka ahụ, otu nkọwapụta, na ịgbado ọkụ na-arụ n'otu oge ahụ, n'oge a, shrinkage ma ọ bụ nrụrụ nke abụọ symmetrical welds. n'akụkụ vetikal nke axis na-anọpụ iche nke ụgbọ elu ahụ ga-edozi ma kagbuo ibe ya.
Ø Iji mee ka eriri weld dị na ụgbọ elu symmetrical ọzọ, eriri weld na ụgbọ elu abụọ ahụ na-agafe welded, ntụziaka ịgbado ọkụ bụ otu, nkọwapụta bụ otu, nke mere na welds niile ga-abụrịrị symmetrical na axis na-anọpụ iche nke akụrụngwa, nke mere na nrụrụ n'ozuzu nke akụrụngwa na-edozi onwe ya ma belata.
(6) Tọọ ịgbado ọkụ reverse deformation dị ka e ji mara nke nkwonkwo
N'ihi na T-ụdị welded nkwonkwo na nnukwu elongation nke nku efere, shrinkage nke weld mgbe ịgbado ọkụ na-akpata ọdịda ala nke outrigger akụkụ nke nku efere, na preset ịgbado ọkụ reverse deformation n'ihu mmepụta bụ irè ịgbado ọkụ usoro ka. chịkwaa nrụrụ ịgbado ọkụ.
A. Gbakọọ ọnụọgụ nrụrụ ma ọ bụ akụkụ nke akụkụ elongated nke efere nku dị ka weld size (ego njuputa), ọnụ ọgụgụ nke ndọtị nku, na ọkpụrụkpụ nke efere nku;
B. Kpọkọtanụ ịgbado ọkụ mgbe ịgbado ọkụ reverse deformation nke preset nku efere dị ka gbakọọ deformation uru;
C. N'ihi na thicker ọkpụrụkpụ nke nku efere, mmepụta nke a pụrụ iche stamping ebu na elu-ike pịa ozugbo ekpochapụ mgbochi deformation;Mgbe emechara mgbakọ nkịtị nke ịgbado ọkụ nke primer, a na-eji usoro ọkụ ọkụ na-eme ka ọ bụrụ ihe na-edozi ihe mgbochi mgbochi nke efere nku.
(7) Usoro ịgbado ọkụ nwere ezi uche
Maka welds dị ogologo, n'okpuru ọnọdụ nke usoro ahụ kwadoro, a ga-agbanwe weld na-aga n'ihu na weld na-adịte aka iji belata nrụrụ;dị ka mgbe akwụsị welds na-adịghị ekwe, a ezi uche ịgbado ọkụ usoro kwesịrị ka ahọrọ ibelata ma ọ bụ kagbuo onye ọ bụla ọzọ si ịgbado ọkụ deformation.Enwere ike ịnakwere usoro ịgbado agbado n'ụkwụ, usoro ịgbado agbado nke obere akụkụ, usoro ịgbado ọkụ, usoro ịgbado ọkụ ọzọ, na usoro ịgbado agbado akụkụ akụkụ.
2. Welding nchekasị njikwa na mkpochapụ usoro
(1) Nchịkwa nke nrụgide ịgbado ọkụ
(1) Usoro nhazi
Ø Wedata ọnụọgụ nke weld na nha nha na nhazi ahụ.
Ø Symmetrical ndokwa nke weld iji zere ịta oke nke welds.
Ø Nabata ụdị nke nkwonkwo na obere siri ike.
(2) Usoro usoro
a.Belata njupụta nke weld iji belata nrụgide fọdụrụnụ nke ịgbado ọkụ
Ø N'ụzọ ezi uche dị na ya mepụta oghere ịgbado ọkụ nke nnukwu efere efere iji belata ọnụ ọgụgụ nke ndochi ịgbado ọkụ;
Ø Jikwaa nhazi nhazi na oghere mgbakọ nke oghere, ma zere ịba ụba nke ndochi ịgbado ọkụ;
Ø Jikwa nnukwu efere T nkwonkwo weld seam iji mee ka akụkụ ịgbado ọkụ sikwuo ike, zere ịba ụba nke ndochi ịgbado ọkụ.
b.Nweta usoro ịgbado ọkụ kwesịrị ekwesị iji belata nrụgide fọdụrụnụ nke ịgbado ọkụ
Ø Mgbe ị na-agbado ọkụ n'otu akụkụ ahụ, a ga-etinye ịgbado ọkụ n'ụdị nkesa okpomọkụ na nkesa symmetrical dị ka o kwere mee;
Ø Mgbe akụrụngwa na-welded, si dịtụ ofu ọnọdụ nke components na onye ọ bụla ọzọ, na ndị na ọnọdụ ndị nwere ukwuu ikwu nnwere onwe ije n'etiti onye ọ bụla ọzọ;
Ø Debe oke mbelata nke ọma tupu oge eruo, a ga-ebu ụzọ kpoo nkwonkwo ahụ nke nwere nhụsianya doro anya, na nkwonkwo na obere nkwụsị ga-agbaji ma emesịa, na ịgbado ọkụ kwesịrị ịgbado n'okpuru obere ihe mgbochi.
c.Gbaa mbọ hụ na preheating okpomọkụ, kacha na kacha nta interlayer okpomọkụ na ịgbado ọkụ kwesịrị ịdị irè ịchịkwa, belata njide ogo nke welded nkwonkwo, belata ịgbado ọkụ okpomọkụ emetụta mpaghara nso, na ibelata ịgbado ọkụ fọdụrụ nchegbu nke oké efere welded nkwonkwo;
d.Nabata usoro ịgbado ọkụ ezi uche dị na ya, dị ka nnukwu agbaze miri emi na-agbaze, nnukwu ugbu a na ụzọ ịgbado ọkụ CO2 nke ọma, nke nwere ike belata ọnụ ọgụgụ nke ọwa ịgbado ọkụ ma belata nrụrụ ịgbado ọkụ na nrụgide fọdụrụnụ;
e.Iji usoro kpo oku na-akwụ ụgwọ iji belata nrụgide na weld: na usoro ịgbado ọkụ, kpoo akụkụ nke ọzọ nke isi ịgbado ọkụ, obosara ikpo ọkụ adịghị erughị 200mm, nke mere na ya na ebe ịgbado ọkụ n'otu oge ahụ gbasaa na nkwekọrịta n'otu oge ahụ, iji nweta ebumnuche nke ibelata nrụgide ịgbado ọkụ.
f.Hammering usoro iji belata residual nchegbu nke ịgbado ọkụ: mgbe ịgbado ọkụ, a aka hama na a obere gburugburu isi ihu na-eji hammer dị nso onuete ebe nke weld, nke mere na metal nke weld na nso onuete ebe nwere ike ịgbatị na nrụrụ, nke a na-eji kwụọ ụgwọ ma ọ bụ mebie nrụrụ rọba mkpakọ emepụtara n'oge ịgbado ọkụ, nke mere na nrụgide fọdụrụ na ịgbado ọkụ na-ebelata.
