WT20 Thoriated Tungsten Electrode bakeng sa TIG Welding
Thorium tungsten electrode ke electrode ea pele ea lefatše e sa tloaelehang ea tungsten e sebelisitsoeng, hape ke mofuta oa li-electrode tsa tungsten tse sebetsang hantle ka ho fetesisa ho fihlela joale.Ts'ebetso ea electrode ea thorium tungsten e molemo ho feta electrode e hloekileng ea tungsten likarolong tse ngata.Thorium oxide e fana ka matla a ho jara hona joale a ka bang 20% ho feta a tungsten e hloekileng, 'me ka kakaretso e na le bophelo bo bolelele ba tšebeletso, e leng ho thusang ho thibela tšilafalo nakong ea ho cheselletsa.Ho sebelisa electrode ea thorium tungsten, ho qala arc ho bonolo, 'me arc e tsitsitse ho feta electrode e hloekileng ea tungsten kapa zirconium tungsten electrode.
Li-electrode tsa thorium tungsten li sebelisoa haholo bakeng sa ho tjheseletsa tšepe e sa hloekang / k'habone / koporo / tšepe / nickel le lisebelisoa tse ling.Haholo-holo haeba hona joale ho sebetsa ho ka holimo ho 200A, ho phaella ho aluminium ea welding, ho kgothaletswa ho sebelisa thorium tungsten e nang le hlooho e khubelu.Hlooho e bohlooho e apara ka potlako tlas'a hona joale e phahameng, e amang phello ea welding.
Likaroloana:
1. Ho bonolo ho sebetsa, mojaro o moholo oa hona joale;
2. Ho bonolo ho qala arc, arc e tsitsitse, 'me lekhalo la ho senya arc le leholo;
3. Tahlehelo e nyenyane le bophelo bo bolelele ba tšebeletso;
4. Phahameng recrystallization mocheso le conductivity molemo;
5. E na le mefuta e mengata ea lisebelisoa 'me e ka kopanya mefuta e mengata ea litšepe le li-alloys.
