Nnwale Post-Weld maka Welding Nut Spot: Ịchọgharị Ohere

Mgbe emechara usoro ịgbado ọkụ ntụpọ nut, ọ dị mkpa iji nyochaa ogo na iguzosi ike n'ezi ihe nke welds.Ịme nnwale n'ihu weld na-enye nghọta bara uru n'ime ihe arụ ọrụ weld, ike na nguzosi ike n'ihe nhazi.Edemede a na-enyocha usoro nnwale dị iche iche nke enwere ike ịrụ iji nyochaa na nyochaa welds ntụpọ nut.

1. Nnwale tensile: A na-ejikarị nnwale tensile iji nyochaa akụrụngwa na ike nke nkwonkwo welded.N'ime nnwale a, a na-edobe usoro nlele welded n'okpuru ike ike ruo mgbe ọdịda.Nsonaazụ na-enye ozi gbasara ike nkwụsị nke kachasị, ike na-enye ike, elongation, na àgwà mgbaji nke welds, na-enyere aka nyochaa arụmọrụ ha n'ozuzu ya na dabara adaba maka ngwa a chọrọ.
2. Nnwale shear: A haziri ule shear ka ọ tụle ike shii na nguzogide weld ntụpọ.Nnwale a na-agụnye idobe ihe nlele welded ka ọ bụrụ ike ịkpacha ihe ruo mgbe ọdịda ga-apụta.Data enwetara, gụnyere ibu shear, nchụpụ, na ọnọdụ ọdịda, na-enyere aka ikpebi ike shear weld na ike ya iguzogide ibu etinyere.
3. Nyocha Microstructural: Nyocha microstructural na-enye ohere nyocha nke nhazi ime weld ma na-enye nghọta n'ime usoro ọka ya, mpaghara okpomọkụ emetụtara, na ntụpọ ọ bụla nwere ike ime ma ọ bụ nkwụsị.Usoro dị ka metallography, microscopy, na scanning eletrọnịkị microscopy (SEM) ka enwere ike iji hụ ma nyochaa microstructure weld, na-enyere aka n'ịtụle ogo ya na ịchọpụta okwu ọ bụla nwere ike imetụta arụmọrụ ya.
4. Nnwale ike ike: A na-eme nnwale ike iji tụọ nkesa ike n'ofe mpaghara weld.Nnwale a na-enyere aka nyochaa iguzosi ike n'ezi ihe nke weld wee chọpụta ọnụnọ mpaghara ọ bụla dị nro ma ọ bụ siri ike nke nwere ike imetụta ike na ịdịte ya.Enwere ike iji usoro dị ka Vickers ma ọ bụ Rockwell hardness test iji chọpụta ụkpụrụ siri ike weld wee chọpụta ọdịiche ọ bụla n'ime nkwonkwo welded.
5. Nnwale na-adịghị emebi emebi (NDT): Usoro nnwale na-adịghị emebi emebi, dị ka nnwale ultrasonic, nnwale eddy ugbu a, ma ọ bụ nnwale redio, enwere ike iji nyochaa ịdị mma n'ime welds na-enweghị mmebi ọ bụla.Ụzọ ndị a nwere ike ịchọpụta ntụpọ, dị ka mgbawa, oghere, ma ọ bụ nsonye, ​​na-ahụ na welds zutere ụkpụrụ na nkọwapụta achọrọ.

Ịme nnwale post-weld dị oke mkpa maka inyocha ịdịmma, ike, na nguzosi ike n'ezi ihe nke welds ntụpọ nut.Nnwale tensile, nnwale shear, nyocha microstructural, ule ike siri ike, na nnwale na-adịghị emebi emebi bụ usoro bara uru nke na-enye ozi dị mkpa gbasara akụrụngwa akụrụngwa nke welds, nhazi ime, yana ntụpọ nwere ike ime.Site n'ime nnwale ndị a, ndị injinia na ndị welders nwere ike hụ na welds zutere ụkpụrụ na ihe achọrọ, si otú a na-ahụ na ntụkwasị obi ha na arụmọrụ ha na ngwa ụwa n'ezie.
