【摘要】：針對(duì)外層引入氮氧混合氣體的氣體熔池耦合活性TIG焊電弧,采用Boltzmann作圖法分析在不同耦合度下電弧等離子體的溫度分布和電弧電壓的變化規(guī)律,并與傳統(tǒng)TIG焊及外層只引入氧氣的氣體熔池耦合活性TIG焊進(jìn)行比較.結(jié)果表明,氮氧聯(lián)合過(guò)渡時(shí)氣體熔池耦合活性TIG焊電弧的中心區(qū)域溫度和電弧電壓均高于傳統(tǒng)TIG焊與外層只引入氧氣時(shí)的氣體熔池耦合活性TIG焊的數(shù)值;當(dāng)耦合度由0變?yōu)?2時(shí),電弧中心區(qū)域溫度與電弧電壓均略有升高.
[Abstract]:In this paper, the temperature distribution and arc voltage variation of arc plasma under different coupling degrees are analyzed by means of Boltzmann drawing method for the active TIG welding arc with nitrogen and oxygen mixed gas in the outer layer. The results are compared with conventional TIG welding and gas pool coupled active TIG welding which only introduces oxygen into the outer layer. The results show that the central temperature and arc voltage of the gas weld pool coupled active TIG welding are higher than those of the conventional TIG welding and the gas weld pool coupled active TIG welding when only oxygen is introduced into the outer layer. When the coupling degree changed from 0 to 2, the temperature and voltage of the arc center increased slightly.
