摘要/Abstract

摘要：

基于电弧光谱诊断和熔池振荡原理分别建立了电弧电子温度和熔池液态金属表面张力动态测量系统，研究了3种典型氧化物焊剂对TIG电弧热源作用下熔池表面张力的影响。结果表明：氧化物的引入不会对电弧整体温度产生明显影响，但能够使熔池液态金属平均表面张力温度梯度由负变正，且熔池表面张力温度梯度与氧化物的熔点有关，氧化物熔点越低，熔池的表面张力温度梯度越大。

Abstract:

A dynamic measurement system of molten pool liquid metal surface tension was established based on the principle of weld pool oscillation. The effect of three typical oxide fluxes on the surface tension of the molten pool under the action of the TIG arc heat source was investigated. It was found that the introduction of oxides does not have a significant effect on overall arc temperature. However， it would cause the average surface tension temperature gradient of liquid metal in molten pool to change from negative to positive， and the surface tension temperature gradient of molten pool is related to the melting point of the oxide. The lower the oxide melting point， the larger the surface tension temperature gradient of the weld pool.

Key words: weld, surface tension of molten pool, weld pool temperature, weld pool oscillation frequency, overall arc temperature, flux
