Kusankha kukula koyenera kwa ma elekitirodi a tungsten kumadalira momwe kuwotcherera komwe kumagwiritsidwa ntchito komanso mtundu wa welder womwe ukugwiritsidwa ntchito. Nawa malangizo ena pakusankha kukula kwa tungsten electrode:

1. Diameter: Makulidwe a electrode ya tungsten ayenera kusankhidwa malinga ndi kuwotcherera pakali pano komanso makulidwe azinthu zomwe zimayenera kuwotcherera. Maelekitirodi ang'onoang'ono ang'onoang'ono ndi oyenera misinkhu yocheperapo pano komanso zinthu zocheperako, pomwe ma elekitirodi okulirapo ndi oyenera milingo yaposachedwa komanso zida zokulirapo.

2. Utali: Kutalika kwa electrode ya tungsten iyenera kusankhidwa potengera makina otsekemera omwe amagwiritsidwa ntchito. Mapangidwe osiyanasiyana amfuti zowotcherera ndi makina owotcherera angafunike kutalika kosiyanasiyana kwa ma elekitirodi kuti awonetsetse kuti ali oyenera komanso akugwira ntchito.

3. Mtundu wamakono: Pa kuwotcherera kwa AC, ma elekitirodi a tungsten oyera kapena maelekitirodi okhala ndi zowonjezera zapadziko lapansi monga cerium amagwiritsidwa ntchito. Pa kuwotcherera kwa DC, ma electrode a thoriated tungsten amagwiritsidwa ntchito. Kukula kwa electrode kuyenera kusankhidwa malinga ndi zofunikira zenizeni za ndondomeko yowotcherera ndi mtundu wamakono omwe amagwiritsidwa ntchito.

Onetsetsani kuti mwayang'ana buku lanu lazowotcherera ndikuganiziranso zowotcherera ndi makulidwe azinthu kuti mudziwe kukula koyenera kwa tungsten electrode pa ntchito yomwe mwapatsidwa. Kuonjezera apo, kukaonana ndi katswiri wowotcherera kapena katswiri kungapereke chidziwitso chofunikira posankha kukula koyenera kwa tungsten electrode pa ntchito inayake yowotcherera.
