产品质量缺陷，并对由此导致的氩弧焊铝护套漏气进行了剖析，结合多年的生产工作经验，通过采取控制电流，气压、调整模子材料，固定焊缝缝隙等一系列措施，并制定操作规范、加大巡检力度，有效控制了氩弧焊产品漏气的发生，节约了原材料提高了产品质量。使公司的产品市场竞争力得到有效的提升。

关键词：高压电缆、金属铝护套、氩弧焊、质量缺陷一、引言

近年来随着国家电力事业的飞速发展，高压电缆产品的需求量也大大增加，我公司为满足市场的需求，拓宽公司产品的供应、适应日益激烈的市场竞争，去年公司引进了一条芬兰超高压立塔生产线，所生产的产品以优良的品质，为公司赢得了良好的信誉和大量的客户。但在长期生产工作中，在铝护套氩弧焊生产工序中发现氩弧焊铝护套偶尔有漏气现象，一直困扰着我们，这不但影响了产品质量，也影响了我们的交货期，为了提高产品质量，本人对产品进行了跟踪、分析、攻关，制定了相应的改进措施，通过在实际生产操作中的有效实施，

二、氩弧焊生产中的缺陷

金属铝护套氩弧焊是采用卷板铝材通过精切、卷筒、焊接，在线检测、轧纹过程来实现，我们在生产过程中发现焊缝经常移位，走“长城形”，造成漏焊、假焊、虚焊经轧纹时就开裂，如果未经处理在用户使用过程中一旦浸水就会产生水树造成绝缘击穿的严重后果，而返工查找缺陷、修补也将造成大量材料和人力的浪费，所以必须找出引发质量缺陷的根本因素，追本溯源提前做好防范工作，才能有效的控制这个问题的发生。

三、影响金属铝护套氩弧焊焊接质量的原因分析

作为高压电缆结构中的金属铝护套对电缆起作防腐、防潮、屏蔽的作用，同时还起着机械保护作用，所以铝管焊缝质量好坏非常关键，是直接影响电缆使用寿命的重要因素之一。

根据我从事金属铝护套生产线多年经验的积累，并对氩弧焊生产流程进行长期跟踪后，发现影响氩弧焊焊接质量的原因主要有以下几个因素：

1、方法因素：在生产过程中控制不当，没依据不同的铝板厚度控制不同电流，另不同的规格控制焊接的速度也不同。

2、人为因素：操作工人操作技能水平不够，责任心不强，不了解焊接的工艺参数，不熟悉各类产品的标准，没选择合适的模具，巡检

3、材料因素：卷板铝材质量差，斑块氧化严重，受潮杂质多，这些不仅会影响焊接过程的正常进行，还会影响到产品质量。

4、设备因素：由于设备不很完善铝板纵包经定经模成型时在运行过程中，合缝位置容易左右移动，使钨极针头不能正对着缝，导致焊接偏移。

四、改进措施

针对上述困素通过详细的调查和分析并结合实际生产情况制定了不同的改进措施加以实施。

4.1方法因素的改进

1）焊接电流、速度直接影响焊接质量，当金属护套采用2.0mm的铝板材时，经总结其电流与速度的关系归纳如下：

总给定（速度） 28% 33% 35% 37% 39% 41% 43% 45% 47% 50% 55% 电流A 85 88 91 100 100 104 108 111 113 117 125 焊机给定 27% 29% 30% 33% 35% 37% 41% 41AAD% 图1：铝护套氬弧焊接电流与速度关系图

另外不同厚度的铝板其焊接电流与速度也要做相应的调整。

2）钨极露出瓷瓶的长度、钨极与铝板的距离高度及钨极表面的光
