Selelekela sa Ts'ebetso ea Stick Welding
SMAW (Shielded Metal Arc Welding) hangata e bitsoa welding stick.Ke e 'ngoe ea mekhoa e tsebahalang haholo ea li-welding e sebelisoang kajeno.Ho tsebahala ha eona ho bakoa ke ho feto-fetoha ha mokhoa oa ts'ebetso le bonolo le theko e tlaase ea thepa le ts'ebetso.SMAW e atisa ho sebelisoa ka lisebelisoa tse kang tšepe e bonolo, tšepe e entsoeng ka tšepe le tšepe e sa hloekang.
Kamoo Stick Welding e Sebetsang Kateng
Stick welding ke mokhoa oa ho tjheseletsa arc ka letsoho.E hloka eleketrode e ka jeoang e koahetsoeng ka phallo ho beha weld, 'me motlakase o sebelisoa ho theha arc ea motlakase pakeng tsa eleketrode le litšepe tse ntseng li chesetsoa hammoho.Motlakase oa motlakase o ka 'na oa e-ba oa motlakase o fapaneng kapa oa hona joale o tobileng ho tloha phepelong ea matla a tjheseletsa.
Ha weld e ntse e behoa, seaparo sa electrode flux se senyeha.Sena se hlahisa mouoane o fanang ka khase e sireletsang le lera la slag.Ka bobeli khase le slag li sireletsa letamo la weld tšilafalong ea sepakapaka.Flux e boetse e sebeletsa ho eketsa li-scavengers, li-deoxidizers, le likarolo tsa alloying ho tšepe ea weld.
Li-electrode tse koahetsoeng ka Flux
U ka fumana li-electrode tse koahetsoeng ka flux ka bophara le bolelele bo fapaneng.Ka tloaelo, ha u khetha electrode, u batla ho bapisa thepa ea electrode le lisebelisoa tsa motheo.Mefuta ea li-electrode tse koahetsoeng ka Flux li kenyelletsa boronse, boronse ba aluminium, tšepe e bonolo, tšepe e sa hloekang le nickel.
Tšebeliso e Tloaelehileng ea Stick Welding
SMAW e tumme haholo lefatšeng ka bophara hoo e laolang lits'ebetso tse ling tsa li-welding indastering ea tokiso le tlhokomelo.E boetse e ntse e tsoela pele ho sebelisoa ka mokhoa o pharaletseng ha ho etsoa liindasteri le kaho ea meaho ea tšepe, le hoja welding ea flux-cored arc e ntse e tsebahala libakeng tsena.
Litšobotsi tse ling tsa Stick Welding
Litšobotsi tse ling tsa Shielded Metal Arc Welding li kenyelletsa:
- E fana ka maemo ohle a feto-fetohang
- Ha e amehe haholo moeeng le lithapong
- Boleng le ponahalo ea weld li fapana ho ea ka bokhoni ba opareitara
- Hangata e khona ho hlahisa mefuta e mene ea manonyeletso a cheselitsoeng: lenonyeletso la butt, lap joint, T-joint, le fillet weld.
