摘要

本研究的目的是开发一种高效、低热输入的二氧化碳弧焊工艺。先前的一篇论文表明，所提出的热线co2电弧焊工艺具有同时实现高效率和低热量输入的潜力。本文研究了采用已开发的热丝co2弧焊工艺，在20mm厚钢板对接接头上仅用两道焊道即可生产出无缺陷、无焊接不稳定现象的良好接头。采用高速成像和截面观测技术对焊接条件进行了优化研究。为避免缺陷的存在和金属液的优先性，得到了焊接电流和送丝速度分别为350A和7.5m/min、400A和5m/min、450A和5m/min、500A和5m/min的优化条件，获得了良好的焊接接头，并具有良好的强度和韧性。

Evaluation of Butt Joint Produced by a Hot-Wire CO2 Arc Welding Method

The purpose of this study was to develop a high-eﬃciency and low-heat-input CO 2 arc-welding process using hot-wire feeding. A previous paper showed that the proposed hot-wire CO 2 arc-welding process has the potential to simultaneously achieve both high eﬃciency and low heat input. This paper investigated the production of a sound joint with only two welding passes on a butt joint of 20mm-thick steel plates with no defects or unstable welding phenomena using the developed hot-wire CO 2 arc-welding process. Welding condition optimization was investigated using high-speed imaging and cross-sectional observations. The optimized conditions, which were the combinations of the welding current and hot-wire feeding speed as 350A and 7.5m/min, 400A and 5m/min, 450A and 5m/min, 500A and 5m/min, derived to avoid the presence of defects and molten metal precedence, which achieved sound welded joints possessing adequate properties of strength and toughness.
