Sengoloa se bua ka bohlokoa ba tumello ea pele ho forging, boleng ba eona bo nepahetseng, le phello ea eona ho boleng le ts'ebetso ea weld. Li-welders li ka rua molemo ka ho utloisisa le ho kenya ts'ebetsong mokhoa ona ho finyella li-welds tse nepahetseng le tse se nang khothatso.

Tumello ea ho cheka pele ke mokhoa oa bohlokoa o sebelisoang mecheng ea ho chesella ho fokotsa mathata a ho khopama ho bakoang ke ho cheselletsa. E kenyelletsa ho qhekella ka leano la workpiece pele ho tjheseletsa, ho fella ka ts'ebetso e laoloang le e nepahetseng ea welding.

1. Ho utloisisa Tumello ea Pre-Forging Allowance Pre-forging allowance e bolela ho holofala ho fokolang kapa ho kobeha ha sesebediswa sa mosebetsi pele ho tjheseletsa.

Ho fihlella tekano e nepahetseng ho bohlokoa ho qoba ho kobeha ho feta tekano, ho ka lebisang litabeng tse kang ho putlama ha weld le ho sotha.
3. Kameho ho Boleng ba Weld le Ts'ebetso Ho kenya tšebetsong tumello e nepahetseng ea ho qhekella ho ka ntlafatsa haholo boleng le ts'ebetso ea weld. Ka ho fokotsa ho sotha, mokhoa ona o tiisa hore motsoako oa weld o boloka sebopeho le boholo ba oona. Li-welds tse se nang tšitiso li kenya letsoho ntlafatsong ea sets'oants'o sa sebopeho, ho nepahala ha sebopeho, le botle ba weld ka kakaretso.

Libaka tsa Kopo: Chelete ea ho tjheseletsa pele ho forging hangata e sebelisoa lits'ebetsong tse fapaneng tsa welding, ho kenyelletsa welding ea butt, welding fillet, le T-joint welding. Ho molemo ka ho khetheha ha o sebetsa ka thepa e teteaneng kapa litlhophiso tse rarahaneng tsa manonyeletso, moo ho ka 'nang ha etsahala hore ho khopame ho etsahala.

Tumello ea ho qhekella esale pele ke mokhoa oa bohlokoa mochining oa welding o thusang ho sebetsana le mathata a ho sotha nakong ea welding. Ka ho kenyelletsa mokhoa ona ts'ebetsong ea ho tjheseletsa le ho etsa qeto ea tumello e nepahetseng e thehiloeng ho lisebelisoa le litlhaloso tse kopanetsoeng, li-welders li ka finyella li-welds tse nepahetseng le tse se nang ho sotha. Tšebeliso e atlehileng ea litsiane tsa pele ho forging e kenya letsoho ho ntlafatseng boleng ba weld, bots'epehi ba sebopeho, le ts'ebetso ea welding ka kakaretso. Joalo ka ts'ebetso ea mantlha indastering ea li-welding, tumello ea pele ho forging e ntse e tsoela pele ho bapala karolo ea bohlokoa ho netefatsa hore ho na le li-weld tsa boleng bo holimo le tse tšepahalang.
