Misiyano huru pakatithoriated tungsten electrodeuye lanthanum tungsten electrode ndeaya anotevera:
1. Zvigadzirwa zvakasiyana
Thoriumtungsten electrode: Izvo zvakakosha zvinoshandiswa ndeye tungsten (W) uye thorium oxide (ThO₂). Zviri mukati me thorium oxide kazhinji pakati pe1.0% -4.0%. Sechinhu cheradioactive, iyo radioactivity yethorium oxide inogona kuvandudza kugona kweerekitironi kune imwe nhanho.
Lanthanum tungsten electrode: Inonyanya kuumbwa ne tungsten (W) uye lanthanum oxide (La₂O₃). Zvinyorwa zve lanthanum oxide zvinenge 1.3% - 2.0%. Iyo ipasi isingawanzo oxide uye haina radioactive.
2. Maitiro ekuita:
Electron emission performance
Thoriumtungsten electrode: Nekuda kwekuora kweradioactive ye thorium element, mamwe maerekitironi emahara anogadzirwa pamusoro peiyo electrode. Aya maerekitironi anobatsira kuderedza kushanda kwebasa re electrode, zvichiita kuti simba rekubudisa maerekitironi rive nesimba. Inogonawo kuburitsa maerekitironi zvakanyanya kudzikama pane tembiricha yakadzikira, izvo zvinoita kuti iite zvirinani mune dzimwe nguva senge AC welding apo kazhinji arc initiation inodiwa.
Lanthanum tungsten electrode: Iyo electron emission performance zvakare yakanaka. Kunyange zvazvo pasina radioactive axiliary emission emission, lanthanum oxide inogona kunatsa chimiro chezviyo zve tungsten uye kuchengetedza electrode pakugadzikana kwakanaka kweelectron emission pakupisa kukuru. Mune iyo DC welding process, inogona kupa yakagadzikana arc uye kuita iyo welding mhando yunifomu.
Kupisa kuramba
Thorium tungsten electrode: Munzvimbo yepamusoro yekupisa, nekuda kwekuvapo kwe thorium oxide, kupisa kwe electrode kunogona kuvandudzwa kune imwe nhanho. Zvisinei, nekuwedzera kwekushandisa nguva uye kuwedzera kwekushongedza ikozvino, musoro we electrode ucharamba uchipisa kune imwe nzvimbo.
Lanthanum tungsten electrode: Iyo ine yakanaka kupisa kuramba. Lanthanum oxide inogona kuumba firimu rinodzivirira pane electrode pamusoro pakakwirira tembiricha kudzivirira imwe oxidation uye kupisa tungsten. Panguva yekushanda kwepamusoro-soro kana kushandiswa kwenguva refu, chimiro chekupedzisira chelanthanum tungsten electrode inogona kuramba yakagadzikana, ichideredza nhamba yekudzokorora kwe electrode.
Arc kutanga kuita
Thorium tungsten electrode: Zviri nyore kutanga arc, nekuti basa rayo rezasi rinobvumira chiteshi chinoitisa kuti chigadzirwe pakati pe electrode uye weldment nekukurumidza panguva yekutanga nhanho, uye arc inogona kubatidzwa zvakanaka.
Lanthanum tungsten electrode: Iyo arc yekutanga kuita yakaderera zvishoma kune iyo yethorium tungsten electrode, asi pasi peiyo yakakodzera welding michina parameter marongero, ichiri kukwanisa kuita yakanaka arc yekutanga maitiro. Uye inoita zvakanaka mukugadzikana kwearc mushure mekutanga kwearc.
3. Mamiriro ekushandisa
Thoriumtungsten electrode
Nekuda kwekuita kwayo kwakanaka kweelectron emission uye arc kutanga kuita, inowanzoshandiswa mu AC argon arc welding, kunyanya kana welding aluminium, magnesium nema alloys ayo nezvimwe zvinhu zvine arc yakakwira yekutanga zvinodiwa. Nekudaro, nekuda kwekuvapo kweradioactivity, kushandiswa kwayo kunodzivirirwa mune dzimwe nguva neakasimba ekudzivirira nemwaranzi zvinodiwa, sekugadzira michina yekurapa, indasitiri yezvikafu welding uye mamwe minda.
Lanthanum tungsten electrode
Nekuti hapana radioactive njodzi, mashandisirwo ayo huwandu hwakakura. Inogona kushandiswa muDC argon arc welding uye mamwe AC argon arc welding mamiriro. Kana welding zvinhu zvakaita sesimbi isina simbi, kabhoni simbi, copper alloy, nezvimwewo, inogona kushandisa yakagadzikana arc kuita kwayo uye kwakanaka kupisa kuramba kuti ive nechokwadi chewelding mhando.
4. Kuchengeteka
Thorium tungsten electrode: Nekuti ine thorium oxide, chinhu chine radioactive chinhu, inoburitsa dzimwe njodzi dzeradioactive panguva yekushandiswa. Kana yakafumurwa kwenguva yakareba, inogona kuve nemhedzisiro yakaipa pahutano hwevashandisi, kusanganisira kuwedzera njodzi yezvirwere zvakaita sekenza. Naizvozvo, kana uchishandisa thoriated tungsten maelectrodes, akasimba ekudzivirira mwaranzi matanho anofanirwa kutorwa, sekupfeka zvipfeko zvekudzivirira uye kushandisa radiation yekutarisa michina.
Lanthanum tungsten electrodes: haina radioactive zvinhu, yakachengeteka zvishoma, uye haifanire kunetseka nezvekusvibiswa kweradioactive panguva yekushandiswa, kusangana nekuchengetedzwa kwezvakatipoteredza uye hutano nekuchengetedza zvinodiwa.
