WC20 Cerium Tungsten Electrode mo te TIG Welding
Ko tecerium tungsten electrodekei roto te 2% cerium oxide.Cerium tungsten electrode he pai mo te DC fehokotaki'anga i ngaohiko iti, no te mea he ngāwari ki te tīmata pewa i ngaohiko iti, a ko reira 10% raro atu i te thorium tungsten i te mahi.Mo te paipa paipa, ko te cerium tungsten electrode te mea rongonui, a ka whakamahia ano hoki ki te wetewete i nga waahanga iti.Ka whakatauritea ki te hiko tungsten parakore, he iti ake te tere o te wera me te tere whakaetonga cerium tungsten electrode.Ka piki ake te ihirangi o te cerium oxide, ka piki ake ano enei painga.Ko te Cerium te teitei o te nekehanga, na i te timatanga o te whakapiri, he tino pai te mahi whakahiato.Ka roa te wa, ka tipu nga kakano karaihe, ka tino heke te neke.Heoi, i raro i te ngaohiko iti, he roa ake te ora i tera o nga hiko thorium tungsten.Na enei ahuatanga ko te nuinga o te waa ka whai hua ki te whakakii i te huringa-poto, i te rahinga whakahiato motuhake ranei i mua i te whakakapi i te hiko.He pai ake te whakamahi i te hiko thorium tungsten electrode ranei lanthanum tungsten electrode mo te teitei o naianei me te ngaohiko hiko.Ka taea hoki te whakamahi i te electrode cerium-tungsten mo te naianei tika, te whakawhiti ranei, engari ko te nuinga o te waa e whakamahia ana mo te whakakii tika, na te mea he ngawari te wehe i te hiko cerium-tungsten i te wa o te hiko AC.
Ka whakatauritea ki te thorium tungsten electrodes, cerium tungsten electrodes i nga painga e whai ake nei: thorium tungsten electrodes he iti radiation, a ka taea anake te mahi i raro i nga ahuatanga o naianei.Heoi, ko te cerium tungsten electrode he rauemi whakahiato kore-radiative a ka taea te whakahaere i te waa iti.Ko te hiko Cerium-tungsten te rereke pai ki te hiko thorium-tungsten.I tua atu, ko te electrode cerium-tungsten he waahi cathode iti, he iti te heke o te pehanga, kaore he wera, na reira ko te nuinga o te waa e whakamahia ana i roto i te argon arc welding.
Āhuatanga:
1. Karekau he iraruke, karekau he parahanga radioactive;
2. He iti te mahi mahi hiko, a he pai te mahi o te arc start me te arc stabilization;
3. Ka ngawari te tiimata o te pewa ki te iti o te waa, a, he iti te waa arc;
4. He iti ake te wera o te wera, te tere whakaetonga ranei, te roa o te mahi
5. He iti te wahi cathode, he iti te hekenga pehanga, kaore e wera
