In terms of construction design, the upper and lower apex assembly was used, and two layers of nylon ply were used as bead reinforcement instead of the exist one layer wire ply; 从施工设计上,采用上下复合三角胶及用2层尼龙加强层替代原一层钢丝加强层等;
However, the experimental results revealed that under the half short circuiting droplet transfer the arc voltage is generally maintained at about 20V with such control system despite arc current, which results in the formation of the narrow weld bead with a shallow penetration and large reinforcement. 但试验发现这一控制策略用于半短路过渡焊,则无论电流选多大,电弧电压常维持在20V左右,所焊焊缝熔宽窄,余高大,熔深浅。
