【摘要】：双丝气体保护焊是一种高效化焊接方法,能够在保证焊接质量的前提下进行高速焊接。本文基于焊接机器人系统,研究了焊接电流、电压和速度对电弧稳定性、飞溅、焊缝成形及微观组织的影响规律,并改进双丝焊工艺。研究结果表明:控制前丝与后丝焊接电流、电弧电压的差值在一定范围内可实现1.2 m/min高效稳定焊接,但当焊接速度进一步提高时会影响焊接质量。优化后的焊接工艺方案:前丝焊接电流260 A、后丝焊接电流240 A、前丝电弧电压24.7 V、后丝电弧电压23.9 V、焊接速度1 m/min。
[Abstract]:Double wire gas shielded welding is an efficient welding method, which can carry out high speed welding under the premise of ensuring welding quality. Based on the welding robot system, the effects of welding current, voltage and speed on arc stability, splashing, weld forming and microstructure are studied in this paper, and the double wire welding process is improved. The results show that 1.2 m/min high efficiency and stable welding can be realized by controlling the welding current and arc voltage difference between the front wire and the rear wire, but the welding quality will be affected when the welding speed is further improved. The optimized welding process scheme is as follows: front wire welding current 260 A, rear wire welding current 240 A, front wire arc voltage 24.7 V, rear wire arc voltage 23.9 V, welding speed 1 m 鈮，
