This paper presents the influence of welding current, electrode-workpiece distance, electrode composition, electrode diameter, electrode tip angle, shielding gas composition, and pulsed current frequency over the arc stagnation pressure of gas tungsten arc welding (GTAW). In this study, arc application tests were carried out over a 1-mm diameter hole on a non-melting water-cooled copper plate. The hole was connected to a differential pressure sensor through an extension tube. As a result, the welding arc pressure was observed to be directly proportional to the square of the welding current and to the tungsten electrode diameter. Moreover, the pressure increases as the electrode-workpiece distance is reduced, and it is inversely proportional to the electrode tip angle, for angles greater than 45°. Also, the electrode composition, the pulsed current frequency, and the gas composition influence the welding arc stagnation pressure.

焊接变量对GTAW电弧停滞压力的影响

本文介绍了焊接电流，气体钨极电弧焊（GTAW）的电弧停滞压力对焊接电流，电极-工件距离，电极组成，电极直径，电极尖端角度，保护气体组成和脉冲电流频率的影响。在这项研究中，在非熔融水冷铜板上的直径为1毫米的孔上进行了电弧施加测试。该孔通过延长管连接到压差传感器。结果，观察到焊接电弧压力与焊接电流的平方和钨电极直径成正比。此外，压力随着电极-工件距离的减小而增加，并且对于大于45°的角度，压力与电极尖端角度成反比。另外，电极组成
