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. Ịkpọ 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 ịgbado ọkụ aluminom na-arụkarị ọrụ na ọkwa dị iche iche na ọkpụrụkpụ nke mkpanaka aluminum. 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 ruo ogo okpomọkụ ebe ọ na-aghọwanye ihe na-anabata okpomọkụ nke 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, ihe mgbaru ọsọ bụ isi 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 eji agbado mkpịrị aluminom bụ ihe dị oke egwu 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 eriri aluminom na-adịgide adịgide na nke a pụrụ ịdabere na ya, na-eme ka ọ bụrụ usoro bara uru n'ọtụtụ ntọala ụlọ ọrụ.
