I-electrode engcono kakhulu ye-tungsten yesicelo esithile ixhomekeke kwizinto ezifana nohlobo lwe-welding, i-welding material kunye ne-welding current. Nangona kunjalo, ezinye ze-tungsten electrode ezisetyenziswa ngokuqhelekileyo ziquka:

1. I-electrode ye-tungsten ethotyiweyo: idla ngokusetyenziswa kwi-DC welding yensimbi engenasici, i-nickel alloy kunye ne-titanium. Baneempawu ezintle zokuqalisa kunye nokuzinza kwe-arc.

2. I-electrode ye-Tungsten-cerium: ifanelekile kwi-AC kunye ne-DC welding, ehlala isetyenziselwa i-welding carbon steel, insimbi engenasici, i-nickel alloy kunye ne-titanium. Baneempawu ezilungileyo zokuqala ze-arc kunye namazinga aphantsi okudinwa.

3. I-Lanthanum Tungsten Electrodes: Ezi zi-electrodes eziguquguqukayo ezifanelekileyo kwi-AC kunye ne-DC welding ye-carbon steel, insimbi engenasici, i-nickel alloys kunye ne-titanium. Banozinzo oluhle lwe-arc kunye nobomi benkonzo ende.

4. I-zirconium tungsten electrode: ngokuqhelekileyo isetyenziselwa i-AC welding ye-aluminium kunye ne-magnesium alloys. Banokuchasana kakuhle nokungcoliseka kunye nokubonelela nge-arc ezinzileyo.

Kubalulekile ukubonisana nengcali ye-welding okanye ubhekiselele kwizikhokelo zesicelo se-welding ethile ukuze unqume i-electrode engcono kakhulu ye-tungsten yomsebenzi othile we-welding.

I-Tungsten ayinamandla kunedayimani. Idayimani yenye yezona zinto zinzima ezaziwayo kwaye ibonakaliswe ngobulukhuni obukhethekileyo kunye namandla. Iqulunqwe ngama-athomu ekhabhoni ahlelwe kwisakhiwo esithile se-crystal, esinika iipropati ezizodwa.

I-Tungsten, kwelinye icala, yintsimbi exineneyo kwaye eyomeleleyo enendawo ephezulu yokunyibilika, kodwa ayiqinanga njengedayimani. I-Tungsten isetyenziswa ngokuqhelekileyo kwizicelo ezifuna amandla aphezulu kunye nokumelana nokushisa, njengokuveliswa kwezixhobo zokusebenza eziphezulu, uqhagamshelwano lombane, kunye noshishino lwe-aerospace.

Isishwankathelo, ngelixa i-tungsten iyinto eyomeleleyo kwaye iqinile, ayinzima njengedayimane. Idayimani isala yenye yezona zinto zinzima kwaye zihlala zihlala ziyaziwa ngumntu.

ITungsten inendawo yokunyibilika ephezulu kakhulu eyi-3,422°C (6,192°F), iyenza ibe yenye yezona ndawo ziphezulu zokunyibilika kuzo zonke izinto. Nangona kunjalo, kukho ezinye izinto kunye neemeko ezinokunyibilikisa i-tungsten:

1. I-Tungsten ngokwayo: I-Tungsten inokunyibilika kusetyenziswa amaqondo obushushu aphezulu kakhulu aveliswa zizixhobo ezikhethekileyo ezifana neziko zombane ze-arc okanye ezinye iindlela zokufudumeza eziphambili.

2. I-Tungsten-rhenium alloy: Ukongeza inani elincinci le-rhenium kwi-tungsten inokunciphisa indawo yokunyibilika kwe-alloy. Le ngxubevange isetyenziswa kwizicelo ezithile zobushushu obuphezulu apho kufuneka indawo yokunyibilika esezantsi.

3. I-Tungsten inokunyibilika kwakhona phambi kweegesi ezithile ezisebenzayo okanye phantsi kweemeko ezithile kwindawo elawulwayo.

Ngokuqhelekileyo, ukunyibilika kwe-tungsten kufuna iimeko ezigqithisileyo ngenxa yendawo ephezulu yokunyibilika kwayo, ekungekho lula ukuyifikelela.
