铝拉杆焊接质量改进措施探讨

Study on the Improvement Measures of the Welding Quality of Aluminum Rod

针对我公司百万伏等级气体绝缘金属封闭式组合电器(GIS)设备使用的铝拉杆焊的气孔缺陷,进行焊接工艺、机加工工艺方法改进的探索研究,通过采取焊前清理、焊前预热、减小焊丝直径、使用氩气保护、分次进行切削加工等改进措施,大幅度提高了该零件的批量合格率,保证了生产进度,减少了废品所造成的经济损失,取得了良好的效果。

For the blowhole defects of aluminum rod welding used in my company's millions of volts rating gas insulated metal enclosed combination(GIS),the improvement measures of welding process and machining process was researched. By adopting cleaning before welding,preheating before welding,reduction of the diameter of welding wire,using argon as gas protection,cutting by several times and other improvement measures,the mass percent of pass was greatly enhanced,the production progress was ensured,the economic loss caused by the wastes was reduced,which achieved good effects.
