Kedu ihe kpatara nnukwu carbon ígwè ji esi ike ịgbado?

Carbon Steel dị elu nwere enweghị ike weldability n'ihi nnukwu carbon ọdịnaya ya.Atụmatụ ịgbado ọkụ bụ ndị a:
(1) adịghị mma thermal conductivity, ịrịba okpomọkụ dị iche n'etiti weld mpaghara na unheated akụkụ.Mgbe ọdọ mmiri a wụrụ awụ jụrụ nke ọma, nrụgide dị n'ime weld nwere ike ịmalite mgbawa ngwa ngwa.
(2) ọ na-enwe mmetụta karịa quenching na martensite na-adị mfe kpụrụ na mpaghara nso nso.N'ihi ọrụ nke nrụgide nhazi ahụ, mpaghara dị nso na-emepụta ihe mgbawa oyi.
(3) n'ihi mmetụta nke okpomọkụ dị elu, ọka na-eto ngwa ngwa, carbide dị mfe ịgbakọ ma na-eto eto na oke ọka, nke na-eme ka weld na-adịghị ike na ike nke nkwonkwo ịgbado ọkụ na-ebelata.
(4) elu carbon ígwè na-yikarịrị na-emepụta na-ekpo ọkụ cracks karịa ọkara carbon ígwè
Igwe carbon dị elu bụ ụdị carbon ígwè nwere w (c)> 0.6%.Ọ na-enwe mmetụta dị ukwuu iji sie ike ma na-etolite carbon martensite dị elu karịa ọkara carbon steel, ọ na-enwekwa mmetụta karịa n'ichebe mgbawa oyi.

Gịnị mere nnukwu carbon ígwè ji siri ike weld

N'otu oge ahụ, ihe owuwu martensite nke e guzobere na HAZ nwere ihe siri ike na nke na-adịghị mma, nke na-eduga ná mbelata nke plasticity na ike nke nkwonkwo.Ya mere, weldability nke elu carbon ígwè dị nnọọ njọ, na pụrụ iche ịgbado ọkụ usoro ga-nakweere, iji hụ na arụmọrụ nke njikọ.
Ya mere, na ịgbado ọkụ Ọdịdị, n'ozuzu adịkarịghị eji.A na-ejikarị ígwè carbon dị elu eme ihe maka akụkụ igwe na-achọ ike siri ike ma na-eyi nguzogide, dị ka rotary shafts, nnukwu gia na couplings.
Iji chekwaa ígwè ma mee ka nkà na ụzụ nhazi dị mfe, a na-emekarị akụkụ igwe ndị a site na nhazi welded.N'ịrụpụta ígwè ọrụ dị arọ, akụkụ carbon ígwè dị elu ga-ezutekwa nsogbu ịgbado ọkụ.
Mgbe ị na-eme usoro ịgbado ọkụ nke akụkụ carbon ígwè dị elu, ọ dị mkpa iji nyochaa ụdị ọ bụla nke ntụpọ ịgbado ọkụ ma were usoro usoro ịgbado ọkụ kwekọrọ.
