Annealing ke ts'ebetso e mahlonoko indastering ea li-welding, haholo mochining oa ho cheselletsa butt.Sengoliloeng sena se bua ka bohlokoa ba annealing, melemo ea eona, le maemo ao ho hlokahalang ho etsa kalafo ena ea mocheso.Ho utloisisa nako ea ho kenya li-annealing ho netefatsa tlhahiso ea li-welded tsa boleng bo holimo tse nang le thepa e ntlafetseng ea mochine.
Selelekela: Annealing ke mokhoa oa ho phekola mocheso o kenyelletsang ho futhumatsa tšepe mochesong o itseng ebe o e pholisa butle-butle ho fetola sebopeho sa eona se senyenyane.Mechineng ea ho cheselletsa butt, annealing e bapala karolo ea bohlokoa ho fokotsa khatello ea maikutlo, ho ntlafatsa ductility, le ho ntlafatsa boleng ba weld ka kakaretso.
- Lisebelisoa tse Matla le tse Matla a Phahameng: Bakeng sa lipoleiti tsa tšepe tse teteaneng kapa lisebelisoa tse matla haholo, ho pholisa ka potlako nakong ea welding ho ka baka ho thatafala le brittleness, e leng se lebisang litabeng tse ka 'nang tsa senyeha.Maemong a joalo, annealing ea hlokahala ho khutlisa ductility le ho tiea ha thepa.
- Khatello ea Maikutlo: Welding e hlahisa likhatello tse setseng sebakeng se kopanetsoeng, tse ka bakang ho khopama kapa ho sotheha ha likarolo tse cheselitsoeng.Annealing e thusa ho imolla likhatello tsena tse setseng, ho khothaletsa botsitso le ho thibela ho khopama.
- Libaka tse thatafalitsoeng: Nakong ea ho cheselletsa, mocheso o sebakeng sa heno o ka etsa libaka tse thata ka har'a tšepe, 'me oa ama hampe botšepehi ba weld.Annealing e nolofatsa libaka tsena tse thata, ho theha microstructure e ts'oanang ho pholletsa le lenonyeletso.
- Post-Weld Heat Treatment (PWHT): Lits'ebetsong tse ling, likhoutu le litekanyetso tse ikhethileng li ka hloka kalafo ea mocheso oa post-weld (PWHT) ho netefatsa bots'epehi ba weld le ho fihlela litlhoko tse ikhethileng tsa thepa.Anealing hangata ke karolo ea tšebetso ea PWHT.
- Ho itokisa bakeng sa tjheseletso e eketsehileng: Ho tjheseletsa ka mefuta e mengata, haholo ha o sebedisa maqheka a fapaneng a ho tjheseletsa kapa disebediswa tsa ho tlatsa, ho tjheseletsa pakeng tsa dipasa ho ka thusa ho thibela ho phatloha ho hoholo le ho etsa bonnete ba ho kopanngwa hantle pakeng tsa masela.
Mechineng ea ho tjheseletsa butt, annealing ke sesebelisoa sa bohlokoa sa ho ntlafatsa boleng ba manonyeletso a cheselitsoeng le ho fokotsa kotsi ea bofokoli le liphoso.Ho tseba nako ea ho kenya li-annealing ho bohlokoa bakeng sa ho fihlela thepa e lakatsehang ea mochini, ho imolla khatello ea maikutlo e setseng, le ho netefatsa nako e telele ea likarolo tse cheselitsoeng.Ka ho kenyelletsa annealing ts'ebetsong ea welding ha ho hlokahala, li-welders li ka hlahisa li-welds tsa boleng bo holimo le tse tšepahalang, tse fihlelang litekanyetso tse thata tsa indasteri le litebello tsa bareki.
