Lintho tse akaretsang ka li-electrode tsa ho tjheseletsa

Tianqiao welding electrode ke khetho ea litsebi

Li-electrode tsa ho tjheseletsa li bohlokoa, 'me ho bohlokoa hore mosebelisi oa litšepe le basebetsi ba amehang ba tsebe hore na ba sebelise mofuta ofe bakeng sa mesebetsi e fapaneng.

Ke eng tjheseletsa li-electrode?

Electrode ke terata e koahetsoeng ea tšepe, e entsoeng ka thepa e ts'oanang le tšepe e ntse e chesoa. Qalong, ho na le li-electrode tse ka sebelisoang le tse sa sebelisoeng. Ho welding ea arc ea tšepe (SMAW) e tsejoang hape e le thupa, li-electrode li ka sebelisoa, ho bolelang hore elektrode e chesoa nakong ea ts'ebeliso ea eona ebe ea qhibiliha le weld. Ho li-electrode tsa Tungsten Inert Gas welding (TIG) 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 fepa terata. 2 Ts'ebetso ea arc-cored arc e hloka motlakase o fepeloang o sa khaotseng o nang le ts'ebetsong.

Tsela ea ho khetha li-electrode tjheseletsa?

Ho khetha eleketrode ho khethoa ke litlhoko tsa mosebetsi oa ho tjheseletsa. Tsena li kenyelletsa:

  • Matla a tšepe
  • Ductility
  • Ts'enyeho hanyetsa
  • Base ea tšepe
  • Weld boemo ba
  • Polarity
  • Hona joale

Ho na le li-electrode tse bobebe le tse boima tse tlotsitsoeng. Li-electrode tse koahetsoeng ke leseli li na le seaparo se bobebe se sebelisoang ka ho borashe, ho fafatsa, ho ina, ho hlatsoa, ​​ho hlakola kapa ho oa. Li-electrode tse boima li koahetsoe ke extrusion kapa ho rotha. Ho na le mefuta e meraro ea mantlha ea ho roala boima: diminerale, selulose, kapa motsoako oa tsena tse peli. Ho sebelisoa liaparo tse boima bakeng sa tšepe, litšepe le bokaholimo bo thata.

Linomoro le litlhaku li bolelang ho melamu ea ho tjheseletsa?

American Welding Society (AWS) e na le sistimi ea linomoro e fanang ka tlhaiso-leseling ka eleketrode e itseng, joalo ka ts'ebeliso ea ts'ebeliso eo e sebelisoang hamolemo bakeng sa eona le hore na e lokela ho sebetsoa joang hore e sebetse hantle.
