摘　　要：气体保护焊中送丝系统送丝的精确性和稳定性对焊接质量有至关重要的影响,随着对焊接熔滴过渡行为研究的深入以及控制理论的发展,出现了许多新的送丝方法。本文介绍了近年来出现的几种新型送丝方法的原理及应用情况,并对未来送丝系统的研究和发展作出了展望。The welding quality is greatly influenced by nicety and stability of wire feeding in gas shielded welding. With the developments of welding droplet transfer and control thesis, many new type methods for wire feeding were come forth. The principles and applications of these new type methods are described,and the prospects for future feeding wire system are also given.
