| 摘 要： | 为实现管道全位置自动根焊,突破了传统的气体保护焊"恒压、等速送丝"系统的电压和送丝速度(即电流)的搭配关系,采用短路能量与燃弧能量自适应调节技术,研制成功专用的电弧能量调节器,通过IGBT的高速开关作用调节短路过渡MAG焊接过程中短路能量和燃弧能量的分配,保证电弧在更低电压、更大电流条件下稳定燃烧,以适应管道全位置根焊在小熔池基础上的高能量输入,实现了长输管线的全位置立向下自动根焊工艺.结果表明,其焊接效率较传统的手工纤维束焊条或TIG焊接工艺打底有明显的提高. |
| 关 键 词： | 管道焊接 根焊 全位置焊接 单面焊接双面成形 |

| Abstract: | A special arc energy regulator is developed to realize the all postion automatic root welding of pipeline welding.This generator adopting the self-adaption technology of short circuit energy and burning energy,breakthrough conventional matching relationship of the output voltage and the wire speed for the GMAW.Ensure the arc stability under the lower voltage and higher current,to adapt the high energy input of the all position root welding of pipeline. |
| Keywords: | pipeline welding root welding all position welding single sided weld with double sided formation |
