Boleng ba li-welds tse hlahisoang ke mechini ea welding ea butt bo susumetsoa ke lintlha tse fapaneng tsa kahare tse ka har'a ts'ebetso ea welding ka boeona. Ho utloisisa lintlha tsena tsa ka hare ho bohlokoa bakeng sa li-welders le litsebi indastering ea li-welding ho fihlela boleng bo holimo ba weld. Sengoliloeng sena se hlahloba lintlha tsa mantlha tse ka amang boleng ba welding mochining oa welding oa butt, se fanang ka leseli mabapi le mokhoa oa ho ntlafatsa likarolo tsena bakeng sa sephetho se atlehileng sa welding.
- Mekhahlelo ea Welding: E 'ngoe ea lintlha tsa bohlokoa tsa mantlha ke khetho le taolo ea liparamente tsa welding, ho kenyeletsoa hona joale oa welding, voltage, lebelo la welding, le ho kenya mocheso. Ho lokisa liparamente tsena ka nepo ho netefatsa fusion e lekaneng, ho kenella, le bots'epehi ba weld ka kakaretso.
- Khetho ea Lintho le Boitokisetso: Khetho ea lisebelisoa tsa ho tjheseletsa le boitokiso ba tsona li phetha karolo ea bohlokoa boleng ba tjheseletsa. Ho sebelisa lisebelisoa tse lumellanang le ho lokisa libaka tse kopanetsoeng ho susumetsa ka ho lekaneng matla le ho tšoarella ha weld.
- Electrode kapa Filler Material: Mofuta le boleng ba elektrode kapa thepa ea ho tlatsa e sebelisoang ts'ebetsong ea welding e ka ama haholo thepa ea metallurgic ea weld. Ho bohlokoa ho khetha electrode e nepahetseng bakeng sa ts'ebeliso e khethehileng bakeng sa ho fumana liphetho tse nepahetseng.
- Mokhoa oa ho tjheseletsa: Mekhoa e fapaneng ea ho tjheseletsa, joalo ka gas tungsten arc welding (GTAW), welding ea tšepe ea gas arc (GMAW), kapa shielded metal arc welding (SMAW), e ka ama boleng ba welding. Mokhoa o mong le o mong o hloka tsebo e khethehileng le ho nepahala ho tsoa ho welder ho fihlela sephetho se lakatsehang.
- Moralo o Kopanetsoeng: Moralo o kopaneng, ho kenyeletsoa geometry le fit-up, o susumetsa boiketlo ba welding le matla a mochini oa weld ea ho qetela. Moralo o nepahetseng oa kopanelo o tiisa kabo e tšoanang ea mocheso le fusion e felletseng.
- Tatelano ea Welding: Tatelano eo ho eona likarolo tse fapaneng tsa lenonyeletso li cheselitsoeng li ka ama likhatello tse setseng le ho sotha. Ho latela tatellano e loketseng ea ho cheselletsa ho bohlokoa ho fokotsa mefokolo e ka bang teng.
- Preheating le Post-Weld Heat Treatment (PWHT): Ho sebelisa mocheso oa preheating kapa post-weld mocheso ho ka fokotsa likhatello tse setseng le ho ntlafatsa microstructure ea weld, e leng se lebisang ho ntlafatso ea thepa ea mechine le boleng bo akaretsang ba welding.
- Tsebo le Koetliso ea Opereishene: Boemo ba bokhoni le koetliso ea mochini oa ho chesella li ama haholo boleng ba litšepe. Mocheso ea koetlisitsoeng hantle le ea nang le boiphihlelo a ka laola lintlha tsa kahare ka nepo mme a hlahisa litšepe tsa boleng bo holimo khafetsa.
Ntlafatsa Lintlha tsa Intrinsic: Ho ntlafatsa boleng ba ho tjheseletsa metjhini ea ho tjheseletsa butt, li-welders le litsebi li lokela ho tsepamisa maikutlo ho ntlafatseng lintlha tsa mantlha:
- Etsa khetho e phethahetseng ea thepa le boitokiso bo kopanetsoeng ho netefatsa ho lumellana le ho lekana hantle.
- Kamehla lekanya le ho lokisa liparamente tsa welding ho tsamaisana le ts'ebeliso e khethehileng ea welding.
- Sebelisa mekhoa e loketseng ea li-welding bakeng sa motsoako oa welding o reretsoeng le mofuta oa thepa.
- Kenya ts'ebetsong mocheso oa preheating kapa post-weld mocheso ha ho hlokahala ho ntlafatsa thepa ea weld.
- Totobatsa koetliso ea li-welder le nts'etsopele ea bokhoni ho boloka boleng bo tsitsitseng ba tjheseletsa.
Qetellong, lintlha tsa kahare li susumetsa haholo boleng ba welding mecheng ea li-butt welding. Ho ntlafatsa liparamente tsa welding, khetho ea thepa, moralo o kopaneng, mekhoa ea ho tjheseletsa, le boiphihlelo ba opareitara ke tsa bohlokoa bakeng sa ho fihlela bots'epehi bo phahameng ba weld le thepa ea mochini. Ka ho sebetsana le lintlha tsena tsa mantlha, li-welders le litsebi li ka phahamisa ts'ebetso ea welding, botsitso le ts'epahalo. Ho totobatsa bohlokoa ba lintlha tsa kahare ho ts'ehetsa tsoelopele ea theknoloji ea welding le ho khothaletsa moetlo oa bokhabane indastering ea licheso.
