Lanthanate tungsten Ingxubevange Rod
Inkcazo
I-Lanthanated tungsten yi-oxidized lanthanum doped tungsten alloy, ehlelwa njenge-oxidized enqabileyo umhlaba we-tungsten (W-REO).Xa i-lanthanum oxide esasaziweyo yongezwa, i-lanthanated tungsten ibonisa ukunyanzeliswa kobushushu, ukuqhutyelwa kwe-thermal, ukumelana nokunyuka, kunye nobushushu obuphezulu be-recrystallization.Ezi zakhiwo zibalaseleyo zinceda i-lanthanated tungsten electrode ifezekise umsebenzi obalaseleyo kwisakhono sokuqala se-arc, ukuchasana nokukhukuliseka kwe-arc, kunye nokuzinza kwe-arc kunye nokulawulwa.
Iipropati
Ii-electrode ze-tungsten zomhlaba ezinqabileyo, ezinjenge-W-La2O3 kunye ne-W-CeO2, zineempawu ezininzi eziphezulu zokuwelda.Ii-electrode ze-tungsten ze-tungsten ezinqabileyo zomhlaba zimela ezona zakhiwo zibalaseleyo phakathi kwe-electrode ye-Gas Tungsten Arc Welding (GTAW), eyaziwa ngokuba yi-Tungsten Inert Gas (TIG) welding kunye ne-Plasma Arc Welding (PAW).Iioksidi ezongeziweyo kwi-tungsten zandisa ubushushu bokubuyisela kwakhona kwaye, kwangaxeshanye, zikhuthaza inqanaba lokukhupha ngokuthoba umsebenzi we-electron we-tungsten.
