Aluminium rod butt welding inzira inoshandiswa zvakanyanya mumaindasitiri akasiyana siyana, inozivikanwa nekugona kwayo kugadzira maweld akasimba uye anogara. Chimwe chinhu chakakosha pakuita uku kudziya kwekutanga, kunosanganisira kusimudza tembiricha yealuminium rods isati yabatanidzwa. Muchikamu chino, tichaongorora kukosha uye zvakanakira preheating mualuminium tsvimbo butt welding michina.
1. Kuderedza Stress
Preheating inotora basa rakakosha mukudzikisa zvakasara zvinonetsa zvinogona kuitika panguva yewelding process. Aluminium, semamwe simbi zhinji, ine katsika kekuita kondirakiti nekuwedzera sezvo ichidziya nekutonhodzwa. Kana simbi dzealuminium dzichikurumidza kupisa uye dzakasungirirwa pasina preheating, kusiyanisa kwakanyanya kwekushisa kunogona kukura mukati mechinhu. Izvi zvinokurumidza kupisa uye kutonhora zvinogona kutungamirira pakuumbwa kwekunetseka kwemukati, izvo zvinogona kuderedza weld uye zvinhu zvakapoteredza.
Nekutanga kupisa simbi dzealuminium, kusiyana kwekushisa uku kunoderedzwa. Kupisa zvishoma nezvishoma kunobvumira kugovera kwekushisa kwakafanana mukati mezvinhu zvose. Nekuda kweizvozvo, iyo weld joint uye nzvimbo dzakatenderedza ruzivo rwakaderedzwa kushushikana, zvichitungamira kune yakasimba uye yakavimbika weld.
2. Mutswe Kudzivirira
Aluminium inotapukirwa nekuputika panguva yewelding process, kunyanya kana paine kungoerekana kwachinja tembiricha. Preheating inobatsira kudzivirira kuumbwa kwekutsemuka nekuita kuti iwedzere kudzora uye zvishoma nezvishoma tembiricha inokwira nekudonha. Mitswe inogona kukanganisa kutendeseka kweweld uye kuderedza simba rayo, zvichiita kuti preheating inhanho yakakosha mukudzivirira kukanganisa weld.
3. Kuvandudza Weldability
Aluminium tsvimbo butt welding michina inowanzo shanda nemagiredhi akasiyana uye ukobvu hwealuminium tsvimbo. Preheating inogona kusimudzira weldability yezvinhu izvi zvakasiyana nekugadzirisa mamiriro eiyo welding process. Iyo inobvumira iyo aluminium kuti isvike kune tembiricha yemhando iyo inova yakanyanya kugamuchira kune welding kupisa, zvichikonzera kuvandudza fusion pakati pematanda.
4. Yakaderedzwa Porosity
Preheating inogonawo kubatsira kuderedza kuumbwa kwehomwe yegesi kana voids mukati me weld, inozivikanwa se porosity. Kana aruminiyamu ichikurumidza kupisa, chero magasi akavharirwa, akadai sehydrogen kana okisijeni, anogona kupukunyuka kubva muzvinhu, achigadzira voids mu weld. Aya ma voids anogona kuderedza weld uye kukanganisa kunaka kwayo. Preheating inoderedza mukana wekupinda gasi uye inosimudzira yunifomu, yakasimba weld.
5. Kuwedzerwa Simba Rakabatana
Pakupedzisira, chinangwa chekutanga chekupisa mualuminium rod butt welding ndechekugadzira yakakwirira-simba, inovimbika welds. Nekudzikisa kushushikana, kudzivirira kutsemuka, kunatsiridza weldability, uye kuderedza porosity, preheating inobatsira pakusikwa kweweld majoini ane epamusoro mechanical zvinhu. Aya majoini anoratidza yakawedzera simba, ductility, uye kuramba kukundikana, kuve nechokwadi chekuti vanosangana nezvinodiwa zvakaomesesa zveakasiyana maindasitiri ekushandisa.
Mukupedzisa, preheating mualuminium rod butt welding machines inhanho yakakosha inopesvedzera zvakanyanya kunaka uye kuita kwema welds anogadzirwa. Inoshanda kuderedza kushushikana, kudzivirira kutsemuka, kuwedzera weldability, kuderedza porosity, uye pakupedzisira kunatsiridza simba rekubatana. Kubatanidza preheating muwelding process kwakakosha kuti uwane yakasimba uye yakavimbika aluminium rod welds, zvichiita kuti ive nzira yakakosha mumaindasitiri mazhinji.
