Kedu ihe m ga-eme ma ọ bụrụ na enwere oghere ịgbado ọkụ na nhazi ihe owuwu ígwè?

N'ime nhazi nke ihe owuwu ígwè, karịsịa na usoro ịgbado ọkụ, e nwere ọtụtụ nkọwa ndị ekwesịrị iburu n'uche ma gbochie tupu oge eruo, dị ka otu esi emeso pores ịgbado ọkụ, nke a kwenyere na ọ bụ nsogbu ogwu nke na-emekpa ọtụtụ ndị na-emepụta ihe nchara.Chọpụta na gị ọzọ.

Mbụ niile, ka anyị ghọta mkpa ụkpụrụ banyere ịgbado ọkụ pores na ígwè Ọdịdị nhazi: nke mbụ na nke abụọ ọkwa welds na-adịghị ekwe ka nwere porosity ntụpọ;A na-ahapụ welds ọkwa nke atọ ka ha nwee dayameta <0.1t na ≤3mm kwa ogologo 50mm nke welds.Enwere oghere ikuku 2;oghere oghere kwesịrị ịbụ ≥ 6 ugboro dayameta nke oghere ahụ.

Ọzọ, anyị ga-enyocha kpọmkwem ihe mere e ji guzobe ndị a ịgbado ọkụ pores na nhazi nke ígwè owuwu:
