Aluminom mkpanaka butt ịgbado ọkụ bụ usoro a na-ejikarị eme ihe na ngwa ụlọ ọrụ dị iche iche, mara maka ikike imepụta welds siri ike ma dịgidere. Otu akụkụ dị mkpa nke usoro a bụ preheating, nke gụnyere ịkwalite okpomọkụ nke mkpanaka aluminom tupu ha ejikọta ọnụ. N'isiokwu a, anyị ga-enyocha mkpa na uru dị na preheating na aluminum rod butt welding machines.
1. Mbelata nchekasị
Ịkpọ ọkụ ọkụ na-ekere òkè dị mkpa n'ibelata nrụgide fọdụrụnụ nke nwere ike ime n'oge usoro ịgbado ọkụ. Aluminom, dị ka ọtụtụ ọla ndị ọzọ, nwere ọchịchọ ịbanye na ịgbasa ka ọ na-ekpo ọkụ ma dị jụụ. Mgbe mkpanaka aluminom na-ekpo ọkụ ngwa ngwa na welded na-enweghị preheating, nnukwu okpomọkụ dị iche iche nwere ike ịmalite n'ime ihe. Nke a na-ekpo ọkụ ngwa ngwa na oyi nwere ike iduga nguzobe nke nrụgide dị n'ime, nke nwere ike imebi weld na ihe ndị gbara ya gburugburu.
Site na ikpocha mkpanaka aluminom, a na-ebelata ihe dị iche iche nke okpomọkụ. Usoro ikpo ọkụ nke nta nke nta na-enye ohere maka nkesa okpomọkụ otu n'ime ihe niile. N'ihi ya, nkwonkwo weld na mpaghara ndị gbara ya gburugburu na-enweta nrụgide belata, na-eduga na weld siri ike na nke a pụrụ ịdabere na ya.
2. Mgbochi mgbape
Aluminom na-enwe ike ịgbawa n'oge usoro ịgbado ọkụ, ọkachasị mgbe enwere mgbanwe okpomọkụ na mberede. Igwe ọkụ na-ekpo ọkụ na-enyere aka igbochi nhazi nke mgbawa site n'ịhụ na ọ na-achịkwa ma jiri nwayọọ nwayọọ na-ebili na ọdịda. Mgbawa nwere ike imebi iguzosi ike n'ezi ihe nke weld wee belata ike ya, na-eme ka ikpo ọkụ dị oke mkpa iji zere ntụpọ weld.
3. Mmelite Weldability
Igwe igwe ịgbado ọkụ aluminom na-arụkarị ọrụ na ọkwa dị iche iche na ọkpụrụkpụ nke mkpanaka aluminom. Preheating nwere ike ịkwalite weldability nke ihe ndị a dị iche iche site n'ịkwalite ọnọdụ maka usoro ịgbado ọkụ. Ọ na-enye ohere ka aluminom rute oke okpomọkụ ebe ọ na-anabatakwu ọkụ ịgbado ọkụ, na-eme ka ọ dịkwuo mma n'etiti mkpanaka.
4. Mbelata Porosity
Ịkpọ ọkụ ọkụ nwekwara ike inye aka belata nguzobe nke akpa gas ma ọ bụ oghere n'ime weld, nke a maara dị ka porosity. Mgbe aluminom na-ekpo ọkụ ngwa ngwa, gas ọ bụla tọrọ atọ, dị ka hydrogen ma ọ bụ oxygen, nwere ike ịgbanarị ihe ahụ, na-emepụta oghere na weld. Ihe efu ndị a nwere ike imebi weld wee mebie ogo ya. Igwe ọkụ na-ekpo ọkụ na-ebelata ohere nke ọnyà gas ma na-akwalite otu ụdị, weld siri ike.
5. Enwetara Ike Njikọta
N'ikpeazụ, isi ihe mgbaru ọsọ nke ikpo ọkụ na aluminom mkpanaka butt welding bụ ịmepụta ike dị elu, nke a pụrụ ịdabere na ya. Site n'ibelata nchekasị, igbochi mgbawa, melite weldability, na ibelata porosity, preheating na-enye aka na ịmepụta nkwonkwo weld nwere ihe ndị dị elu. Njikọ ndị a na-egosipụta ike dị ukwuu, ductility, na iguzogide ọdịda, na-ahụ na ha na-emezu ihe siri ike nke ngwa ọrụ mmepụta ihe dị iche iche.
Na mmechi, ịgbanye ọkụ n'ime igwe igwe ịgbado ọkụ mkpisi aka aluminom bụ nzọụkwụ dị oke mkpa nke na-emetụta ịdịmma na arụmọrụ nke welds emepụtara. Ọ na-eje ozi iji belata nchekasị, gbochie mgbawa, welie weldability, belata porosity, na n'ikpeazụ kwalite ike nkwonkwo. Ịtinye preheating n'ime usoro ịgbado ọkụ dị mkpa maka ịnweta mkpanaka aluminom na-adịgide adịgide na nke a pụrụ ịdabere na ya, na-eme ka ọ bụrụ usoro bara uru n'ọtụtụ ntọala ụlọ ọrụ.
