Usoro nhazi nke Weld Spot n'ime igwe igwe ịgbado ọkụ

N'ógbè nke nut spot welding machines, nhazi nke weld spots bụ usoro dị oké mkpa nke na-ekpebi ike na ntụkwasị obi nke nkwonkwo. Ịghọta mgbagwoju anya nke usoro nhazi a dị oké mkpa maka ịnweta welds dị elu na ngwa dị iche iche. Isiokwu a na-enyocha usoro nzọụkwụ-site-nzọụkwụ nke ka e si emepụta ntụpọ weld n'ime igwe igwe ịgbado ọkụ.

1. Nkwadebe dị n'elu: Tupu ịmalite usoro ịgbado ọkụ, a ga-ehichapụrịrị elu nke workpieces na mkpụrụ iji wepụ ihe ọ bụla na-emerụ emerụ ma ọ bụ oxide n'ígwé. Nke a na-eme ka kọntaktị metal-to-metal kacha mma, nke dị mkpa maka ịnweta nkwonkwo weld siri ike ma dịgidere.
2. Kọntaktị Electrode: Ka igwe ịgbado ọkụ ntụpọ na-arụ ọrụ, electrodes na-eme kọntaktị na workpiece na aku. Ngwa nke nrụgide na-enyere aka nguzobe njikọ eletriki ma na-ebute ntinye nke ịgbado ọkụ ugbu a.
3. Heating Joule: The eruba nke ịgbado ọkụ ugbu a site na electrode na workpiece site Joule kpo oku na ebe kọntaktị. Nke a na-ebute mgbaze nke igwe n'ime mpaghara, na-eke ọdọ mmiri weld gbazere.
4. Nkesa ọkụ: N'oge usoro ịgbado ọkụ, nkesa okpomọkụ na-arụ ọrụ dị oke mkpa n'ịchịkwa nha na omimi nke ebe weld. Kwesịrị ekwesị okpomọkụ nkesa ana achi achi na mgbaze metal penetrates na workpieces na aku n'ụzọ dị irè, akpụ a ike metallurgical njikọ.
5. Solidification: Dị ka ịgbado ọkụ ugbu a na-akwụsị, metal a wụrụ awụ ngwa ngwa cools na solidifies, fusing na workpiece na nut ọnụ. Usoro nke siri ike na-emetụta ihe eji arụ ọrụ nke ebe weld, gụnyere ike na ike ya.
6. Mmetụta na-ekpo ọkụ: N'ọnọdụ ụfọdụ, ebe weld nwere ike ịnweta mmetụta na-ekpo ọkụ, ebe mpaghara okpomọkụ metụtara na-enwe mmetụta dị jụụ na-achịkwa iji belata nrụgide fọdụrụnụ ma melite ductility nkwonkwo.
7. Nyocha ogo: Mgbe usoro ịgbado ọkụ gachara, a na-enyocha ntụpọ weld ahụ siri ike iji hụ na nnabata na nkọwapụta na ụkpụrụ achọrọ. Enwere ike iji usoro nyocha dị iche iche na-adịghị emebi emebi iji nyochaa iguzosi ike n'ezi weld.

Usoro nhazi nke ntụpọ weld n'ime igwe ịgbado ọkụ nut bụ njikọ siri ike nke ọkụ eletrik, ọgbọ okpomọkụ, na ngwakọta ọla. Site na nkwadebe elu nke ọma, ngwa ngwa nke ịgbado ọkụ ugbu a, na nkesa ọkụ kwesịrị ekwesị, a na-enweta ntụpọ weld dị elu, na-enye aka na ike zuru oke na arụmọrụ nke nkwonkwo welded. Ịghọta na njikarịcha usoro nhazi a bụ ihe kachasị mkpa maka ijide n'aka na ntụkwasị obi na ịdịte aka nke ihe ndị welded na ngwa ụlọ ọrụ dị iche iche.
