Lintho tse akaretsang ka li-Electrode tsa Welding
Tianqiao welding electrode ke khetho ea litsebi
Li-electrode tsa welding li bohlokoa, 'me ho bohlokoa hore motho ea chesehelang le basebetsi ba amehang ba tsebe hore na ba sebelise mofuta ofe mesebetsing e fapaneng.
Li-electrode tsa welding ke eng?
Electrode ke terata ea tšepe e koahetsoeng, e entsoeng ka thepa e tšoanang le tšepe e cheselitsoeng.Ho qala, ho na le li-electrode tse ka sebelisoang le tse sa sebelisoeng.Ka thebe ea tšepe ea arc welding (SMAW) e tsejoang hape e le thupa, li-electrode li ka sebelisoa, ho bolelang hore electrode e jeoa nakong ea tšebeliso ea eona mme e qhibiliha ka weld.Ho Tungsten Inert Gas welding (TIG) li-electrode ha li sebelisoe, kahoo ha li qhibilihe ebe li fetoha karolo ea weld.Ka Gas Metal Arc Welding (GMAW) kapa MIG welding, li-electrode li lula li feptjoa ka terata.2 Flux-cored arc welding e hloka hore ho be le motlakase o feptjoang o sa khaotseng o nang le flux.
Mokhoa oa ho khetha li-electrode tsa welding?
Ho khetha electrode ho khethoa ke litlhoko tsa mosebetsi oa ho tjheseletsa.Tsena li kenyelletsa:
- Matla a tšepe
- Ductility
- Khanyetso ea kutu
- Motheo oa tšepe
- Boemo ba weld
- Polarity
- Hona joale
Ho na le li-electrode tse koetsoeng tse bobebe le tse boima.Li-electrode tse koahetsoeng ka khanya li na le seaparo se khanyang se sebelisoang ka ho hlatsoa, ho fafatsa, ho qoelisoa, ho hlatsoa, ho phumula kapa ho oela.Li-electrode tse boima tse koahetsoeng li koahetsoe ke extrusion kapa ho rotha.Ho na le mefuta e meraro e meholo ea liphahlo tse boima: liminerale, selulose, kapa motsoako oa tse peli.Liaparo tse boima li sebelisoa bakeng sa ho cheselletsa tšepe e entsoeng ka tšepe, litšepe le libaka tse thata.
Linomoro le litlhaku li bolela eng holim'a lithupa tsa ho cheselletsa?
American Welding Society (AWS) e na le tsamaiso ea linomoro e fanang ka tlhahisoleseding e mabapi le electrode e itseng, joalo ka hore na ke kopo efe e sebelisoang hantle le hore na e lokela ho sebelisoa joang bakeng sa katleho e kholo.
