Ikibazo cyo gusudira intege nke cyangwa "imbeho" - aho guhuza bidahagije biganisha ku mbaraga zidahagije - bikomeje kuba inzitizi ikomeye mu guhimba aluminium. Nkuko inganda nkimodoka, ibikoresho bya elegitoroniki, hamwe nindege bigenda byishingikiriza kumiterere ya aluminiyumu yoroheje, kwemeza kwizerwa nibyingenzi. Aka gatabo gatanga ingamba zifatika, inganda - ingamba zishyigikiwe zo gukuraho imbeho ikonje mugutezimbereimashini yo gusudirano kugenzura inzira.
Sobanukirwa n'imbogamizi: Impamvu Aluminium Umwanya wo gusudira birananirana
Kugirango usudire neza aluminium, umuntu agomba kubanza kumva imiterere yihariye yumubiri ituma bigorana cyane ugereranije nicyuma. "Ubukonje bukonje" ni urugingo rugaragara rwubatswe hejuru ariko rukabura guhuza imbere bisabwa (gushiraho nugget), bikavamo isano idakomeye, itizewe.
Igisobanuro cyubukonje bukonje
Urudodo rukonje, bakunze kwitwa "gusudira ibinyoma" cyangwa "gusudira mu buryo butemewe," bibaho mugihe ubushyuhe butangwa mugihe cyo gusudira ahantu hadahangarwa bidahagije kugirango habeho nugget ikwiye gushonga hagati yimpapuro zombi zicyuma. Uku kubura guhuza bivuze ko guhuza gushingira gusa kumuvuduko wubukanishi no guhuza byimbere, biganisha kunanirwa imburagihe mukibazo.
Ihame ry'akazi ryo kunanirwa
Impamvu zambere zitera gusudira gukonje muri aluminium yashinze imizi mubumenyi bwibikoresho:
- 1.Inzira ya Oxide: Aluminium isanzwe ikora urwego ruto, rukomeye rwa oxyde ya aluminium (Al₂O₃) hejuru yacyo. Iyi oxyde ifite aho ishonga irenga dogere 2000 (dogere 3,632 F), iruta kure cyane icyuma cya aluminiyumu cyashonga cya dogere 660 (dogere 1,220 F). Uru rupapuro rwirwanya cyane rukora nka insulator, rukabuza umuyoboro wo gusudira gutemba kandi bikabyara ubushyuhe bukenewe bwo guhuza.
- 2.Gukwirakwiza Ubushyuhe bukabije: Aluminium ifite amashanyarazi menshi (inshuro enye z'icyuma) hamwe n'ubushyuhe bwo hejuru (inshuro eshatu z'ibyuma). Ubushyuhe butangwa kuri interineti bukorwa vuba kure ya weld. Niba ingufu zo gusudira zidatanzwe hamwe nubucucike buri hejuru cyane nigihe gito, ubushyuhe buzashira mbere yuko nugget yashongeshejwe.
- 3.Kugenzura Imyuka idahwitse: Ubworoherane bwa aluminium ituma yumva cyane imbaraga za electrode. Imbaraga nyinshi zigabanya kurwanya guhura, biganisha ku kubyara ubushyuhe budahagije. Imbaraga nke cyane zirashobora gutera gusebanya birenze (kwirukana) hamwe na electrode.
Igisubizo: Kunoza imashini yawe yo gusudira ya Aluminium
Kurandura imbeho ikonje bisaba uburyo bwuzuye butangirana nibikoresho bikwiye no kugenzura neza inzira.
Ibyiza bya Medium Frequency DC (MFDC) Ikoranabuhanga
Kumurongo wo hejuru - ubudodo bwiza bwa aluminiyumu, urwego rwinganda rwahindutse ruva mu gusudira gakondo rwa AC rujya muri tekinoroji ya Medium Frequency Direct Current (MFDC). Ibyiza ni ngombwa:
- Icyerekezo n'umuvuduko: Sisitemu ya MFDC ikorera kumurongo mwinshi (mubisanzwe 1.000 Hz kugeza 4000 Hz), itanga igihe cyo gusubiza kiri munsi ya milisegonda 0.5. Uku gutanga ingufu byihuse, neza ningirakamaro mugutsinda aluminiyumu yumuriro mwinshi.
- Ingufu: Ibisohoka DC bigabanya igihombo cyinductive, bigatuma inzira irushaho gukomera - ikora neza kandi ihamye ugereranije na sisitemu ya AC.
- Kuzunguruka.
Igenzura ryuzuye
Gusudira Aluminium bisaba ibipimo bitandukanye cyane nicyuma - mubisanzwe inshuro 2 kugeza kuri 3 zubu nigihe gito cyo gusudira, nkuko byagenwe nibipimo nka AWS C1.1 na ISO 18595.
| Ubunini bwibikoresho (mm) | Imbaraga za Electrode (kN) | Kuzenguruka (KA) | Igihe cyo gusudira (Amagare / 60Hz) | Intego ya Nugget Diameter (mm) |
| 0.8 | 2.0 - 3.0 | 18 - 22 | 3 - 5 | 4.5 - 5.0 |
| 1.2 | 3.0 - 4.5 | 24 - 30 | 5 - 8 | 5.5 - 6.0 |
| 1.5 | 4.0 - 5.5 | 28 - 35 | 6 - 10 | 6.0 - 7.0 |
Imyitozo myiza: Shyira mubikorwa gahunda - ingengabihe yo gusudira. Imbere ya - gusudira irashobora gukoreshwa kugirango ucike mu gice cya oxyde, ugakurikirwa ningenzi nyamukuru yo gusudira kugirango uhuze, hamwe na post - weld temper pulse kugirango ugabanye umuvuduko ukonje kandi ugabanye gucika.
Ibyingenzi Byambere - Gutegura Ubuso Bwuzuye
Ubuso busukuye ntabwo - bwumvikane. Ndetse imashini yateye imbere cyane yo gusudira ntishobora kwishyura imiterere mibi yubutaka.
- Isuku rya mashini: Koresha ibyuma byabugenewe byabugenewe cyangwa ibyuma byabigenewe kugirango ukureho oxyde.
- Isuku ryimiti: Koresha aside yoroheje cyangwa alkaline ibisubizo bya deoxidation ya chimique.
- Igihe Kumva: Aluminium itangira re - okiside ako kanya. Gusudira bigomba gukorwa mu masaha 2 kugeza kuri 8 yo kwitegura hejuru kugirango habeho guhangana.
Gucunga Electrode no Kubungabunga
Umuringa wa electrode na aluminiyumu byoroshye kuvangwa n'ubushyuhe bwinshi, bigatuma isura ya electrode yandura kandi igahindura imiterere (gukomera).
- Imiterere ya Electrode: Koresha dome - ishusho ya electrode ifite radiyo yo mumaso ya 50mm kugeza 100mm.
- Kwambara byikora: Shyira mubikorwa sisitemu yo kwambara ya electrode. Electrode igomba kwambarwa byoroheje nyuma ya buri 50 kugeza 100 yo gusudira kugirango ikomeze geometrie kandi ikore neza, byemeze imikorere yimashini yawe yo gusudira ikomeza kuba nziza.
Kugenzura ubuziranenge no gukomeza kunoza
Kugira ngo ubuziranenge burambye, shyira mu bikorwa uburyo bukomeye bwo kugenzura:
- Ikizamini Cyangiza: Ibizamini bya peel bisanzwe nibyingenzi kugirango hamenyekane diameter ya weld nugget yujuje ubunini busabwa.
- Non - Ikizamini Cyangiza (NDT): Kubisabwa bikomeye, koresha ibizamini bya ultrasonic cyangwa dinamike yo kugenzura kugirango ugenzure inenge zimbere utarimbuye igice.
- Kwinjira: Koresha sisitemu ya IoT (IIoT) kugirango wandike ibigezweho, imbaraga, nigihe cyateganijwe kuri buri weld, utanga ibisobanuro byuzuye kandi byorohereza iterambere rihoraho.
Umwanzuro
Kurandura imbeho ikonje muri aluminiyumu bisaba kwiyemeza neza neza mubyiciro byose. Mugushora imari muri tekinoroji ya MFDC, gukurikiza umurongo ngenderwaho utajenjetse, no gukomeza ubuso bukomeye hamwe nubuyobozi bwa electrode, ababikora barashobora kugera kubintu byizewe, bihanitse - imbaraga zujuje cyangwa zirenga ibipimo byinganda.
