Li-parameter tsa welding li bapala karolo ea bohlokoa mochining oa ho tjheseletsa butt, kaha li hlalosa litlhophiso tse ikhethileng tse hlokahalang ho fihlela sephetho se nepahetseng sa welding. Ho utloisisa mekhahlelo ena le bohlokoa ba eona ho bohlokoa bakeng sa li-welders le litsebi indastering ea li-welding. Sengoliloeng sena se hlahloba likarolo tsa welding ho lintlha tsa mochini oa welding oa butt, se totobatsang karolo ea bona ea ho netefatsa li-welds tse nepahetseng le tsa boleng bo holimo.
- Tlhaloso ea Mekhatlo ea Welding: Mekhahlelo ea ho tjheseletsa e bua ka sete ya boleng bo itseng bo laolang tshebetso ya ho tjheseletsa mochining wa welding butt. Mekhahlelo ena e kenyelletsa welding hajoale, voltage, lebelo la phepelo ea terata, mocheso oa preheating, le mocheso oa interpass, har'a tse ling.
- Welding Current le Voltage: Hona joale oa welding le voltage ke lintlha tsa bohlokoa tse khethollang hore na mocheso o kenang lenonyeletsong la weld. Taolo e nepahetseng ea litekanyetso tsena e netefatsa palo e nepahetseng ea mocheso o hlokahalang bakeng sa ho kopanya hantle le ho kenella ha weld.
- Wire Feed Speed: Lebelo la phepelo ea terata le laetsa sekhahla seo eleketrode ea tjheseletsa e feptjoang ka sona lenonyeletsong la weld. Ho fetola lebelo la phepelo ea terata ho bohlokoa bakeng sa ho boloka arc e tsitsitseng le ho fihlela sebopeho sa lifaha tse tšoanang.
- Mocheso oa Preheating: Mocheso oa ho futhumatsa ke mocheso oo tšepe ea motheo e futhumatsoang ka oona pele ho tjheseletsa. Ke paramente ea bohlokoa bakeng sa ho thibela ho phatloha le ho fokotsa kotsi ea likoli tse bakoang ke hydrogen.
- Mocheso oa Interpass: Mocheso oa mocheso oa Interpass o bolela mocheso oa tšepe ea motheo pakeng tsa li-welding tse latellanang. Ho laola mocheso oa interpass ho bohlokoa bakeng sa ho fokotsa kotsi ea mathata a amanang le mocheso le ho etsa bonnete ba hore ho na le fusion e nepahetseng pakeng tsa li-pass.
- Sekhahla sa Phallo ea Khase e Sireletsang: Mekhoeng e sebelisang likhase tse sireletsang, joalo ka MIG kapa TIG welding, sekhahla sa phallo ea khase e sireletsang ke parameter ea bohlokoa. Phallo e nepahetseng ea khase e tiisa tšireletso e lekaneng ea letamo la weld ho tloha tšilafalo ea sepakapaka.
- Moralo o Kopanetsoeng le Fit-Up: Moralo o kopaneng le ho lekana ke lintlha tsa bohlokoa bakeng sa mechini ea ho tjheseletsa butt. Motsoako o lokiselitsoeng hantle o nang le motsoako o nepahetseng o tiisa hore ho tjheseletsa ka mokhoa o ts'oanang le ho kopanya hantle.
- Kalafo ea Mocheso oa Post-Weld (PWHT): Bakeng sa lisebelisoa le lisebelisoa tse khethehileng, phekolo ea mocheso oa ka mor'a weld e ka 'na ea hlalosoa ka mekhahlelo ea welding. PWHT e thusa ho imolla khatello ea maikutlo e setseng le ho ntlafatsa thepa ea weld.
Qetellong, li-parameter tsa welding ke lintlha tsa bohlokoa ho litlhaloso tsa mochini oa welding oa butt, tse laolang litlhophiso tse hlokahalang bakeng sa ts'ebetso e atlehileng ea welding. Hona joale welding, voltage, wire feed speed speed, preheating thempereichara, interpass rate, shield gase flow rate, joint design, fit-up, le post-weld heat treatment ke lintlha tsa bohlokoa tse tlatsetsang boleng ba weld le botšepehi. Ka ho khomarela ka hloko litlhaloso tsa ho cheselletsa le ho laola litekanyo tsena ka hloko, li-welders le litsebi li ka fumana li-welds tse nepahetseng le tsa boleng bo phahameng lits'ebetsong le liindastering tse fapaneng. Ho totobatsa bohlokoa ba li-parameter tsa welding ho netefatsa ts'ebetso ea ts'ebetso ea mochini oa welding oa butt, e lebisang lits'ebetsong tse sireletsehileng le tse tšepahalang tsa ho kopanya tšepe.
