摘要/Abstract

摘要：

综述了穿孔等离子弧焊接工艺的特点、种类及工艺参数匹配与焊缝质量之间的关系等方面的问题。指出穿孔等离子弧焊具有特殊的“小孔效应”，与钨极氩弧焊相比焊接速度、工件厚度和焊接效率都有了很大的提高。等离子弧焊接衍生出众多类型，包括直流等离子弧焊接、脉冲等离子弧焊接、变极性等离子弧焊接和特殊等离子弧焊接等，能够满足不同行业的特殊需求。本文对于指导实际焊接生产，进一步提高生产效率和焊缝质量具有重要的意义。

Abstract:

This paper surveys the characteristics, classification and the parameters matching for the technology of keyhole plasma arc welding. Keyhole plasma arc welding can cause a special keyhole, with which welding speed, workpiece thickness and welding efficiency will be all increased significantly. It can be generalized to constant, pulsed, variable polarity and special plasma arc welding, so it can satisfy special requirements of many different industries. This paper is quite significant to guide welding practice and increase productivity and the quality of welding joints.

Key words: plasma arc welding, high energy density welding, keyhole
