Quality akara nke welded nkwonkwo

Ịgbado ọkụ bụ nnọọ ewu ewu na ndị ahụ mgbe ọ dị mkpa jikọọ ọnụ metal mmiri nke ọ bụla Ọdịdị, na n'ihi compound kwesịrị na-abụghị kemwepu. E nwere ọtụtụ iche nke usoro a, ma na-kewara abụọ sara mbara ige. Ke akpa idaha, wụrụ awụ nne na nna metal n'oge guzobe nke onuete ga-eme nke abụọ - dịghị. N'agbanyeghị usoro a họọrọ, bụ àgwà akara nke welded nkwonkwo ga-mgbe-emezu. Nke a ga-a nkwa nke àgwà na anwụ ngwa ngwa nke okokụre ngwaahịa

Quality akara nke welded nkwonkwo na-ahụ mgbe nile na na zuru nnabata ya na ụkpụrụ, nke, dabere na nzube nke na-ewu, na-GOST ma ọ bụ SNIP, inye iwu usoro na a chọrọ maka ndị na-agba ọsọ usoro nke ụdị ọrụ. Dị ka a na-achị, ọ mejupụtara abụọ n'ụzọ:

• Izere omume ntụpọ. Mgbe a na ogbo, ọ na-achịkwa ndị isi metal, na ụdị nile nke ịgbado ọkụ ihe, nnabata technology ka na njikere nke nkọwa maka ịgbado ọkụ. Ọtụtụ mgbe na-eji n'ime ebe a na visual nnyocha usoro. Ọ na-achọpụtazi na ngwá na welder ruru eru. Karịsịa na otu ebe imewe nke oké egwu owuwu emepụta.
• Nchọpụta nke ntụpọ. E nwere ọtụtụ na-eji ndị na-abụghị na-ebibi ule usoro na-eme ka o kwe omume iji mata ihe niile kwere omume ntụpọ na Weld onuete enweghị enye nsogbu ya ike n'ezi ihe.

The ikpeazụ ogbo anyị ga-ele anya na ihe zuru ezu. N'ụzọ doro anya, Weld àgwà akara a rụrụ iji mata mpụga, esịtidem na site ntụpọ. Iji malite site visual nnyocha kwuru:

• ụfọdụ guzobere ma ụgbọ elu;
• enweghị Fusion, na nke e nweghị ihe jikọrọ n'etiti nkpọwa nke isi metal mkpụrụ na oyi akwa (ma ọ bụ n'ígwé);
• nepolnomernost;
• slag inclusions;
• anya cracks;
• ebelata;
• nnukwu pores.

Ọbụna ma ọ bụrụ na Weld bụ n'ụzọ zuru ezu-agbanwe agbanwe na ya chọrọ, i.e. were were n'ime ndị nne na nna metal ma ọ bụ nwere melkocheshuychatuyu ezigbo n'elu na-enweghị ntụpọ e ji mara, àgwà akara nke welded nkwonkwo site visual nnyocha nke okokụre ngwaahịa na-okokụre. Isi ihe ize ndụ zoro n'ime nwere ike onuete. Nkwarụ nwere ike ghara hụrụ anya, ma, ha nwere ike ịghọ a kasị akpata na-atụghị anya mmebi nke welded Ọdịdị.

Ne seams ntụpọ nwere ike achọpụtara, e.g., iji ultrasound ma ọ bụ dai penetrant. Ke akpa idaha, a pụrụ iche ngwaọrụ, ụkpụrụ nke ime ihe dabeere emission nke ultrasonic mmiri na ebili mmiri nke, tupu eru cracks ma ọ bụ pores na-dere na ike a na-oyiyi na ihuenyo nke ngwaọrụ. Nke abụọ ahụ na-etinyere àkù nke na a ogbenye mma nke Weld penetrates ndị na-abụghị akụkụ nke isiokwu na-egosipụta site na nke abụọ isi. Nke a na usoro nwere ike ịchọpụta cracks, ọbụna dị nnọọ obere size.

Ọzọkwa welded nkwonkwo àgwà akara nwere ike mere site na ya achọpụta na àgwà nke ule samples mere si na otu ihe dị ka okokụre ngwaahịa. Na nke a na n'ibu Njirimara nke nwalere Weld metal na laabu, nke ga-egbo ụfọdụ ibiere. Karịsịa, na mgbakwunye na nke ike ọdụdọ, ekweghị ekwe na elongation, kpebisiri ike site gbagọrọ agbagọ n'akuku na ike. Ọzọkwa kwadebe mkpa ngalaba, ikwe ka n'ụzọ ziri ezi chọpụta àgwà nke mgbọrọgwụ penetration na-ekpughe esịtidem Weld ntụpọ.
