Mokhoa oa ho kopanya liathomo mecheng ea ho cheselletsa butt ke karolo ea bohlokoa ea ts'ebetso ea bona.Sengoliloeng sena se hlahloba mefuta e fapaneng ea maqhama a athomo e amehang mochining ona le hore na e kenya letsoho joang ts'ebetsong ea welding.
Selelekela: Mechini ea ho cheselletsa butt e bapala karolo ea bohlokoa ho kopanyeng likarolo tsa tšepe ka ts'ebetso e kenyelletsang ho hokahana ha liathomo.Ho bohlokoa ho utloisisa mekhoa e fapaneng ea maqhama a athomo ho utloisisa hore na mechini ena e sebetsa hantle joang.
- Metallic Bonding:
- Mechining ea ho tjheseletsa butt, bonding ea tšepe e atile, kaha litšepe li sebelisoa hangata lits'ebetsong tsa welding.
- Metallic bonding e etsahala ha liathomo tsa tšepe li arolelana lielektrone tsa tsona tsa valence, li etsa "leoatle" la li-electrone tse sarolotsoeng tse phallang ka bolokolohi ho pholletsa le mohaho oa tšepe.
- Tlamahano ena e fella ka lisebelisoa tse matla le tse tenyetsehang tsa tšepe, tse bohlokoa bakeng sa ho hlahisa litšepe tse tiileng le tse tšepahalang.
- Covalent Bonding:
- Lits'ebetsong tse ling tsa welding, covalent covalent bonding le eona e ka bapala karolo ha ho chesetsoa thepa e seng ea tšepe e kang polasetiki kapa lirafshoa.
- Covalent bonding e kenyelletsa ho arolelana lipara tsa elektronike lipakeng tsa liathomo tse haufi, ho theha meaho e tsitsitseng ea limolek'hule.
- Mechineng ea ho cheselletsa butt, covalent bonding e ka sebelisoa ha ho chesetsoa thepa e sa ts'oaneng, e hlokang hore ho thehoe maqhama a covalent lipakeng tsa liathomo tse fapaneng.
- Ionic Bonding:
- Le hoja e sa tloaelehe haholo mecheng ea li-welding tsa butt, li-ionic bonding li ka etsahala ha thepa ea ho cheseletsa e nang le boleng bo fapaneng haholo ba elektronegativity.
- Ho kopana ha Ionic ho bakoa ke ho fetisoa ha lielektrone ho tloha ho athomo e 'ngoe ho ea ho e' ngoe, e leng se lebisang ho thehoeng ha li-cations tse nang le chelete e ntle le li-anion tse qosoang hampe.
- Lits'ebetsong tse ling tsa ho tjheseletsa tse kenyelletsang lirafshoa kapa li-composite, li-ionic bonding li ka ba tsa bohlokoa, haholo-holo lits'ebetsong tsa mocheso o phahameng.
- Mabotho a Van der Waals:
- Mechini ea ho cheselletsa butt e kanna ea kenyelletsa matla a fokolang a limolek'hule a tsejoang e le mabotho a van der Waals.
- Matla a Van der Waals a hlaha ka lebaka la ho fetoha ha nakoana ha matla a elektronike ka har'a liathomo kapa limolek'hule, e leng se bakang matla a nakoana pakeng tsa tsona.
- Le hoja matla ana a fokola ha a bapisoa le mefuta e meng ea ho kopanya, a ntse a ka kenya letsoho tabeng ea ho khomarela lintho tse bonahalang maemong a itseng a tjheseletsa.
Mechineng ea ho tjheseletsa butt, maqhama a liathomo ke ts'ebetso e rarahaneng le e matla, e kenyelletsang motsoako oa litšepe, covalent, ionic, le van der Waals, ho ipapisitse le lisebelisoa tse cheselitsoeng.Ho utloisisa mekhoa ena ea ho kopanya ho bohlokoa bakeng sa ho ntlafatsa ts'ebetso ea welding le ho netefatsa li-welds tse matla le tse tšoarellang.Ka ho sebelisa thepa e ikhethang ea bonding ea athomo, mechini ea welding ea butt e tsoela pele ho ba lisebelisoa tsa bohlokoa liindastering tse fapaneng, e fana ka tharollo e sebetsang le e tšepahalang ea ho kopanya likarolo tsa tšepe.
