摘要
高强焊接用盘条适合于生产650 MPa CO2气体保护镀铜焊丝,其焊接工艺性能良好,要求盘条具有良好的综合力学性能,以便于拉拔加工。高强焊接用盘条在镀铜过程中有严重的镀铜不均匀、镀铜后镀层脱落及焊接过程中飞溅等现象,实验室模拟分析认为线材的组织缺陷是晶界氧化,控制退火温度不超过690℃,可以减少晶界氧化,防止镀铜脱落。
The high - strength welding -purpose wire bar is suitable to produce 650 MPa CO2 -protected copperplated welding wires. It has defects in copper plating： copper plating layer being serious uneven and dropping, splashing in welding. It is analyzed with simulation in laboratory that is because of grain boundary oxidation in structure of wire. It can be prevented with annealing temperature controlled below 690 ℃.
