关于pt.，见同上，第18卷，第1431页(1985)。建立了开式弧焊熔滴过渡模型，为预测焊接工艺参数对稳流焊接和脉冲焊接的影响提供了理论依据。可以用与现有观测结果大体一致的简单表达式来表示结果。考虑了液滴的演化、脱离频率和大小、脉冲参数的选择、静电应力对传递的影响、液滴动力学以及力平衡传递途径与现有不稳定性模型之间的关系。
For pt.I see ibid., vol.18, p.1431 (1985). A model of metal transfer in open arc welding is developed which provides a framework for predicting the influence of welding parameters in steady and pulsed current welding. It is found possible to present results in terms of simple expressions which are in broad agreement with available observations. Considered here are aspects such as droplet evolution, detachment frequency and size, selection of pulse parameters, influence of electrostatic stress on transfer, drop dynamics and the relationship between balance of force approaches to transfer and the present instability model.
