- Lisosa tsa Motso oa Post-Weld Voids: Lintlha tse 'maloa li ka kenya letsoho ho thehoeng ha lefeela ka mor'a ho tjheseletsa ka mechini ea ho cheselletsa linate. Tsena li kenyelletsa ho lumellana ha li-electrode tse sa lokelang, khatello e sa lekaneng ea li-electrode, mocheso o sa lekaneng oa mocheso, tšilafalo holim'a libaka tsa welding, kapa ho hloekisa ka mokhoa o sa lekaneng oa sebaka se kopanetsoeng. Ho tseba sesosa sa sesosa ke habohlokoa ho phethahatsa litharollo tse nepahetseng.
- Litharollo bakeng sa Formation ea Post-Weld Void: a. Ntlafatsa Tekanyetso ea Electrode: Etsa bonnete ba hore ho lumellana ho nepahetseng pakeng tsa electrode le linate nakong ea ts'ebetso ea welding. Ho se tsamaisane hantle ho ka fella ka kabo ea mocheso e sa lekanang le ho kopanngoa ho sa fellang. Fetola boemo ba li-electrode ho fihlela kamano e nepahetseng le ho tsamaisana le bokaholimo ba linate. b. Eketsa Khatello ea Electrode: Khatello e sa lekaneng ea li-electrode e ka lebisa kamanong e mpe pakeng tsa electrode le linate, e leng se etsang hore ho be le fusion e sa fellang. Eketsa khatello ea li-electrode ho netefatsa ho kopana ho lekaneng le ho ntlafatsa phetisetso ea mocheso bakeng sa fusion e nepahetseng. c. Fetola Mocheso: Kenyelletso e sa lekaneng kapa e feteletseng ea mocheso e ka kenya letsoho ho thehoeng ha lefeela. Fetola li-parameter tsa welding, tse kang ho tjheseletsa hona joale le nako, ho finyella mocheso o nepahetseng bakeng sa lisebelisoa tse khethehileng tsa linate le tlhophiso e kopanetsoeng.

Ho sebetsana le sebopeho sa post-weld void mochining oa ho cheselletsa linate ho hloka mokhoa o hlophisitsoeng oa ho tseba le ho rarolla lisosa. Ka ho ntlafatsa tekano ea li-electrode, ho eketsa khatello ea li-electrode, ho lokisa ho kenya mocheso, ho etsa bonnete ba hore libaka tse hloekileng tsa welding, ho kenya ts'ebetso e nepahetseng ea ho hloekisa manonyeletso, le ho lekola mekhoa ea li-welding, li-welders li ka fokotsa ho hlaha ha li-voids le ho fumana li-welds tse matla le tse tšepahalang. Ho kenya ts'ebetsong litharollo tsena ho ntlafatsa boleng ba weld ka kakaretso, matla a kopaneng, le bots'epehi ba sebopeho lits'ebetsong tsa ho cheselletsa linate.
