摘　　要：电弧电流密度和电弧压力是焊接过程中两个重要的参数。论文综述了测量电弧电流密度和电弧压力的常用方法。测量电弧电流密度的方法包括分裂阳极法、烧蚀痕迹分析法、高速摄影法等间接测量法和探针法等直接测量法,其中详细论述了分裂阳极法。测量电弧压力的方法主要是指非熔化极焊接的电弧压力测量方法,包括传感器的连续测量法和气压计的静态测量法等。Arc current density and arc pressure are two important parameters in the arc welding process. Some common methods to measure arc current density and are pressure were summarized in this paper. The methods to measure arc current density could be divided into indirect methods and direct methods. The former included the split anode method, the analysis for ablating trace, optical method and so on. The Split anode method was discussed in detail. The latter included the probe method. The methods to measure arc pressure were mainly used in the non-consumable gas shielded arc welding, which included continuous measurement method of sensors and the static measurement method of Barometer.
