Mekhoa e fapaneng ea li-welding

Ho cheselletsa moea o chesang ho boetse ho bitsoa ho cheselletsa moea o chesang. Moea o hatelitsoeng kapa khase ea inert (hangata naetrojene) e futhumatsoa ho mocheso o hlokahalang ka heater ka sethunya sa tjheseletsa ebe e fafatsoa holim'a bokaholimo ba polasetiki le lesela la welding, e le hore tse peli li qhibilihe ebe li kopantsoe tlas'a khatello e nyane. Lipolasetiki tse utloang oksijene (joaloka polyphthalamide, joalo-joalo) li lokela ho sebelisa khase e se nang moea e le setsi sa ho futhumatsa, 'me lipolasetiki tse ling ka kakaretso li ka sebelisa moea o tlhotliloeng. Hangata mokhoa ona o sebelisoa bakeng sa lipolasetiki tsa ho cheselletsa tse kang polyvinyl chloride, polyethylene, polypropylene, polyoxymethylene, polystyrene le carbonate.
