摘要： An electrode is provided for use in a plasma arc torch. The electrode includes a body having a forward portion, a middle portion and an aft portion. The forward portion includes an electrode tip comprising a conductive first material, wherein the electrode tip includes: 1) a pilot contact region for initiating a pilot arc across the nozzle and 2) an emitter. The middle portion comprises a second material and defines a proximal end for mating with the forward portion and a distal end for mating with the aft portion. The material density of the second material is at least half of the material density of the first material. The electrode also includes an electrically conductive path extending from the forward portion to the aft portion of the body.

摘要： A nozzle for use in a plasma arc torch is provided. The nozzle includes an aft portion comprising a conductive first material with a first density. The aft portion defines a proximal end and a distal end. The nozzle includes a substantially hollow forward portion including 1) a tip section comprising a conductive second material with a second density, and 2) a rear section configured to couple the forward portion to the proximal end of the aft portion. The second density is at least two times greater than the first density. The nozzle further includes a plasma exit orifice disposed in the tip section of the forward portion.
