WC20 Cerium Tungsten Electrode bakeng sa TIG Welding
Thecerium tungsten electrodee na le 2% cerium oxide.Cerium tungsten electrode e loketse bakeng sa tjheseletsa ea DC ka matla a tlaase, hobane ho bonolo ho qala arc ka matla a tlaase, 'me e tlase ka 10% ho feta thorium tungsten mosebetsing.Bakeng sa welding ea liphaephe, electrode ea cerium tungsten ke eona e tummeng ka ho fetisisa, 'me hangata e sebelisoa ho cheselletsa likaroloana tse nyane.Ha ho bapisoa le electrode e hloekileng ea tungsten, electrode ea cerium tungsten e na le sekhahla se tlase sa ho chesa kapa sekhahla sa mouoane.Ha litaba tsa cerium oxide li ntse li eketseha, melemo ena e boetse e eketseha.Cerium e na le motsamao o phahameng ka ho fetisisa, kahoo qalong ea welding, ts'ebetso ea welding e ntle haholo.Ha nako e ntse e ea, ha lijo-thollo tsa kristale li ntse li hōla, ho tsamaea ho tla fokotseha haholo.Leha ho le joalo, tlas'a matla a tlaase, nako ea bophelo e telele ho feta ea bathorium tungsten electrode.Ke ka lebaka la litšoaneleho tsena hangata ho leng molemo ho tjheseletsa nako e khuts'oane kapa molumo o itseng oa welding pele elektrode e ka nkeloa sebaka.Ho molemo ho sebelisa electrode ea thorium tungsten kapa lanthanum tungsten electrode bakeng sa ho tjheseletsa ha motlakase ho phahameng hona joale.Electrode ea cerium-tungsten e ka boela ea sebelisoa bakeng sa hona joale ka ho toba kapa hona joale, empa e sebelisoa haholo-holo bakeng sa ho tjheseletsa hona joale ka ho toba, hobane electrode ea cerium-tungsten e bonolo ho arohana nakong ea AC welding.
Ha ho bapisoa le li-electrode tsa thorium tungsten, li-electrode tsa cerium tungsten li na le melemo e latelang: li-electrode tsa thorium tungsten li na le mahlaseli a fokolang, 'me li ka sebetsa feela tlas'a maemo a phahameng a hona joale.Leha ho le joalo, electrode ea cerium tungsten ke lisebelisoa tse se nang mahlaseli a mahlaseli 'me li ka sebetsoa ka nako e tlaase.Electrode ea Cerium-tungsten ke khetho e khethiloeng ho feta thorium-tungsten electrode.Ho phaella moo, electrode ea cerium-tungsten e na le matheba a manyenyane a cathode, ho theoha ha khatello e tlaase, 'me ha ho na mollo, kahoo ke eona e sebelisoang ka ho fetisisa ho argon arc welding.
Likaroloana:
1. Ha ho mahlaseli, ha ho tšilafalo ea mahlaseli;
2. Mosebetsi oa mosebetsi oa elektronike o tlaase, 'me ts'ebetso ea ho qala ha arc le ho tsitsisa arc e ntle haholo;
3. Arc e ka qalisoa habonolo ka motlakase o monyenyane, 'me motlakase oa arc o monyenyane;
4. Sekhahla se tlaase sa ho chesa kapa sekhahla sa mouoane, bophelo bo bolelele ba tšebeletso
5. Sebaka sa cathode se senyenyane, khatello ea khatello e nyenyane, 'me ha e chese
