Abstract The proposed configurations of non-consumable electrodes allow arcing with a diffuse cathode spot in a wide range of the welding current and exhibit longer service lives as compared to those of cone electrodes, which significantly enhance the arc welding characteristics in inert atmosphere. The effect of the geometric parameters of the electrode working area on the weld penetration depth, width, and geometric factor was investigated. It was found that the maximum value of penetration depth was achieved using the electrode with a slot in the working area and a cut along the welding direction, which enabled welding at relatively high speed and heat input leading to the formation of high-quality seams. The electrode with a cut across the welding direction exhibits the minimum penetration depth and maximum geometry factor and thus is most suitable for high-performance surfacing.

非自耗电极配置对弧焊特性的影响

摘要 与锥形电极相比，非自耗电极的建议配置允许在较宽的焊接电流范围内以扩散阴极点进行电弧放电，并具有更长的使用寿命，这显着提高了惰性气氛中的弧焊特性。研究了电极工作区的几何参数对焊缝熔深、宽度和几何因素的影响。结果表明，使用在工作区域有槽并沿焊接方向切割的焊条可实现熔深的最大值，这使得焊接速度和热量输入相对较高，从而形成高质量的焊缝。
