Kedu ihe bụ Fusion Nugget? Usoro nhazi Fusion Nugget na Ọkara-Frequency Inverter Spot Welding

N'ime usoro ịgbado ọkụ na-agbanwe agbanwe-frequency inverter, nhazi nke fusion nugget na-arụ ọrụ dị oke mkpa n'inweta weld siri ike na ntụkwasị obi. Edemede a na-achọ ịkọwa echiche nke fusion nugget wee banye n'ime usoro nhazi ya na ịgbado ọkụ na-agbanwe agbanwe ugboro ugboro.

1. Fusion Nugget: Ngwakọta nugget na-ezo aka na mpaghara ihe a wụrụ awụ nke na-etolite n'oge usoro ịgbado ọkụ. Ọ bụ n'ihi oke ọkụ na-ebute site na nguzogide eletrik n'etiti workpieces na etinyere ịgbado ọkụ ugbu a. The fusion nugget bụ maka ijikọ workpieces ọnụ, na-eke a siri ike na-adịgide adịgide weld nkwonkwo.
2. Usoro nke Fusion Nugget Formation: Nhazi nke fusion nugget na ịgbado ọkụ na-agbanwe agbanwe ugboro ugboro gụnyere ọtụtụ usoro:

a. Kọntaktị na mkpakọ: A na-ewebata ihe arụrụ arụ a ga-agbado na kọntaktị ma jikọta ya ọnụ site na ike electrode. Nke a na-eme ka kọntaktị chiri anya ma guzobe ụzọ na-eduzi maka ịgbado ọkụ ugbu a.

b. kpo oku: Ozugbo workpieces na kọntaktị, a elu ịgbado ọkụ ugbu a na-agafe ha. Igwe ọkụ eletrik na ntanetị na-emepụta okpomọkụ, na-ebuli ngwa ngwa okpomọkụ na mpaghara kọntaktị. Okpomọkụ na-eme ka ihe ahụ dị nro ma mesịa gbazee, na-eme ọdọ mmiri a wụrụ awụ.

c. Ịgwakọta na Solidification: Ka ịgbado ọkụ ugbu a na-aga n'ihu na-asọpụta, ihe a wụrụ awụ sitere na abụọ workpieces na-agwakọta ọnụ na ọdọ mmiri a wụrụ awụ. Nke a na-akwalite mgbasa nke atọm na-eme ka e guzobe nke metallurgical agbụ n'etiti workpiece ihe. Ọdọ mmiri a wụrụ awụ wee malite ịgbasi ike ka okpomoku na-apụ apụ, na-akpụ ngget ahụ.

d. Njikere na Nkwado: Mgbe agbanyụrụ ịgbado ọkụ ugbu a, ngwungwu ngwakọta na-amalite ajụkwa ma sie ike. Ọnụọgụgụ jụrụ oyi na-emetụta microstructure na akụrụngwa akụrụngwa nke weld. Njụjụ a na-achịkwa na-enye ohere ka e guzobe usoro metallurgical chọrọ ma hụ na ike weld kwesịrị ekwesị.

3. Ihe na-emetụta Fusion Nugget Formation: Ọtụtụ ihe nwere ike imetụta nguzobe nke fusion nugget na ịgbado ọkụ na-agbanwe agbanwe ugboro ugboro:

• Ịgbado ọkụ ugbu a: ịdị ukwuu nke ịgbado ọkụ ugbu a na-emetụta kpọmkwem ọgbọ okpomọkụ na, ya mere, nha na omimi nke fusion nugget.
• Ike Electrode: Nrụgide etinyere na-ekpebi mpaghara kọntaktị n'etiti workpieces, na-emetụta nkesa okpomọkụ na nguzobe nugget.
• Oge ịgbado ọkụ: Ogologo oge nke usoro ịgbado ọkụ na-emetụta ọnụọgụ ọkụ na nha nke nugget ngwakọta.
• Njirimara ihe: conductivity, ọkpụrụkpụ, na mejupụtara nke workpiece ihe na-emetụta ha iguzogide ugbu a eruba na, N'ihi ya, okpomọkụ ọgbọ na fusion nugget guzobe.

The fusion nugget bụ ihe dị mkpa akụrụngwa iji nweta ihe ịga nke ọma weld na ọkara-frequency inverter ntụpọ ịgbado ọkụ. Ịghọta usoro nhazi nugget fusion na ihe ndị na-emetụta ya nwere ike inye aka kwalite welding parameters, jikwaa àgwà weld, na hụ na ike na ịdịte aka nke nkwonkwo weld. Site na iji nlezianya jikwaa ịgbado ọkụ ugbu a, ike elektrọd, oge ịgbado ọkụ, na ihe onwunwe, welders nwere ike nweta nhazi nugget na-agbanwe agbanwe na ntụkwasị obi, na-eduga na weld ntụpọ dị elu.
