I-electrode ye-tungsten engcono kakhulu yohlelo oluthile incike ezintweni ezifana nohlobo lwe-welding, impahla yokushisela kanye ne-welding current. Kodwa-ke, amanye ama-electrode e-tungsten avame ukusetshenziswa afaka:

1. I-thoriated tungsten electrode: imvamisa isetshenziselwa ukushisela i-DC yensimbi engagqwali, i-nickel alloy ne-titanium. Banezakhiwo ezinhle zokuqala ze-arc nokuzinza.

2. I-electrode ye-Tungsten-cerium: ifanele i-AC ne-DC welding, evame ukusetshenziselwa ukushisela i-carbon steel, insimbi engagqwali, i-nickel alloy ne-titanium. Banezakhiwo ezinhle zokuqala ze-arc kanye namazinga aphansi okutubeka.

3. I-Lanthanum Tungsten Electrodes: Lawa ama-electrode ahlukahlukene afanele i-AC ne-DC welding ye-carbon steel, insimbi engagqwali, ama-nickel alloys kanye ne-titanium. Banokusimama okuhle kwe-arc nempilo ende yesevisi.

4. I-Zirconium tungsten electrode: ngokuvamile isetshenziselwa ukushisela i-AC ye-aluminium nama-alloys e-magnesium. Banokumelana okuhle nokungcola futhi banikeze i-arc ezinzile.

Kubalulekile ukuthintana nochwepheshe wokushisela noma ubhekisele kumhlahlandlela wohlelo lokushisela othile ukuze unqume i-electrode engcono kakhulu ye-tungsten yomsebenzi othile wokushisela.

I-Tungsten ayinamandla kunedayimane. Idayimane ingenye yezinto ezilukhuni kunazo zonke ezaziwayo futhi ibonakala ngobulukhuni namandla angavamile. Yakhiwe ngama-athomu ekhabhoni ahlelwe ngesakhiwo esithile sekristalu, esinikeza izakhiwo eziyingqayizivele.

I-Tungsten, ngakolunye uhlangothi, iyinsimbi eminyene kakhulu futhi eqinile enephuzu eliphakeme lokuncibilika, kodwa ayiqinile njengedayimane. I-Tungsten ijwayele ukusetshenziswa ezinhlelweni ezidinga amandla aphezulu nokumelana nokushisa, njengokukhiqizwa kwamathuluzi asebenza kahle kakhulu, othintana nabo kagesi, kanye nemboni ye-aerospace.

Kafushane, ngenkathi i-tungsten iyinto eqinile futhi eqinile, ayinzima njengedayimane. Idayimane lihlala lingenye yezinto eziqinile futhi ezihlala isikhathi eside ezaziwa umuntu.

I-Tungsten inephuzu lokuncibilika eliphakeme kakhulu elingu-3,422°C (6,192°F), okuyenza ibe yindawo ephezulu yokuncibilika kuzo zonke izakhi. Kodwa-ke, kunezinye izinto nezimo ezingancibilikisa i-tungsten:

1. I-Tungsten ngokwayo: I-Tungsten ingancibilika kusetshenziswa amazinga okushisa aphakeme kakhulu akhiqizwa izinto ezikhethekile ezifana neziko likagesi ze-arc noma ezinye izindlela zokushisisa ezithuthukisiwe.

2. Ingxubevange ye-Tungsten-rhenium: Ukwengeza inani elincane le-rhenium ku-tungsten kunganciphisa iphuzu lokuncibilika kwe-alloy. Le alloy isetshenziswa ezindaweni ezithile zokushisa okuphezulu lapho kudingeka khona indawo encibilikayo ephansi.

3. I-Tungsten ingaphinde incibilike phambi kwamagesi athile asebenzayo noma ngaphansi kwezimo ezithile endaweni elawulwayo.

Ngokuvamile, ukuncibilika kwe-tungsten kudinga izimo ezimbi kakhulu ngenxa yezinga layo eliphakeme lokuncibilika, ngokuvamile okungelula ukulifinyelela.
