Mumadziwa bwanji za zida zowotcherera? Musaphonye kuchuluka kwakukulu! (II)

4. Aluminiyamu aloyi

Monga ife tonse tikudziwa, matenthedwe madutsidwe aloyi zotayidwa ndi mkulu kwambiri. Kuphatikiza apo, ma aluminiyamu aloyi amakhalanso ndi mawonekedwe apamwamba. Chifukwa chake, ngati kuwotcherera kwa laser kumafunika pazitsulo za aluminiyamu, mphamvu zambiri zimafunikira. Mwachitsanzo, mndandanda wamba 1 mpaka 5 ukhoza kuwotcherera ndi laser. Zoonadi, palinso zigawo zina zosasunthika muzitsulo zotayidwa, monga pepala lopangidwa kale, kotero n'zosapeŵeka kuti nthunzi ina idzalowa mu weld panthawi yowotcherera, motero kupanga mabowo a mpweya. Komanso, mamasukidwe akayendedwe a aluminiyamu aloyi ndi otsika, kotero ife tikhoza kusintha zimenezi kudzera olowa mapangidwe pa kuwotcherera.

5. Titaniyamu/titaniyamu aloyi

Titaniyamu aloyi ndi zinthu wamba kuwotcherera. Kugwiritsa ntchito kuwotcherera kwa laser kuti kuwotcherera aloyi ya titaniyamu sikumangopeza zolumikizira zapamwamba, komanso kukhala ndi pulasitiki yabwinoko. Popeza zinthu za titaniyamu ndizopepuka komanso zakuda chifukwa cha kusiyana komwe kumapangidwa ndi gasi, tiyenera kusamala kwambiri ndi chithandizo chamagulu ndi chitetezo cha gasi. Pa kuwotcherera, chidwi ayenera kuperekedwa kwa ulamuliro wa haidrojeni, amene angathe bwino kuchepetsa kuchedwa akulimbana chodabwitsa titaniyamu aloyi mu ndondomeko kuwotcherera. Porosity ndiye vuto lofala kwambiri la zida za titaniyamu ndi ma aloyi a titaniyamu pakuwotcherera. Nazi njira zina zothandizira kuthetsa porosity: choyamba, argon ndi chiyero choposa 99,9% akhoza kusankhidwa kuti aziwotcherera. Kachiwiri, akhoza kutsukidwa pamaso kuwotcherera. Pomaliza, zowotcherera za titaniyamu ndi titaniyamu aloyi ziyenera kutsatiridwa mosamalitsa pakuwotcherera. Mwanjira iyi, kubadwa kwa pores kumatha kupewedwa kwambiri.

6. Mkuwa

Anthu ambiri sangadziwe kuti mkuwa ndi chinthu chodziwika bwino pakuwotcherera. Zida zamkuwa nthawi zambiri zimakhala ndi mkuwa ndi mkuwa wofiyira, zomwe zimakhala ndi zida zapamwamba zowunikira. Posankha mkuwa ngati zinthu zowotcherera, tcherani khutu pazomwe zili mkati mwake. Ngati zomwe zili pamwambazi ndizovuta kwambiri, vuto la kuwotcherera kwa pepala lamalata lomwe latchulidwa pamwambapa lidzachitika. Pankhani ya mkuwa wofiira, chidwi chiyenera kulipidwa ku mphamvu yamagetsi panthawi yowotcherera. Kuchulukana kwamphamvu kokha kumatha kukhutiritsa ntchito yowotcherera yamkuwa wofiira.
Awa ndi mapeto a kufufuza wamba kuwotcherera zipangizo. Tafotokoza mwatsatanetsatane zida zofananira, tikuyembekeza kukuthandizani
