[机械]带极埋弧自动焊技术操作规程

作者[孙锡云] 发表于[2012-4-9 10:02:00]

带极埋弧自动焊技术操作规程

1、 主题内容与适用范围

本标准规定了LG1200R型带埋弧自动焊机的技术操作要求和作业程序

本标准适用于LG1200R型焊机的操作

2、 引用标准

参照西德进口的LG1200R型焊机说明书

GBJ236—现场设备、工业管道焊接工程施工及验收规范

3、操作前的准备

3．1操作人员必须了解焊机构造原理，熟悉其机械系统，电气系统，熟悉电源箱和操作盘上的各种开关，旋钮的功能，了解焊机的主要技术参数。

3．2操作前应熟悉图纸及被焊工件的材质，堆焊部位等有关技术要求。

3．3工作前对焊带和焊剂要做质量检查，有产品出产合格证的方可使用。对焊带上的油污和铁锈要清除，对焊剂要按工艺要求进行烘焙。

3．4堆焊前，要对工件上堆焊部位的铁锈和油污清除干净。

3．5根据堆焊的工艺要求，选择下降性（DP），平特性（CP）或平特性的气保焊（MAG）电源特性曲线，并将转换开关搬到对应的位置上。

3．6根据工艺要求选定直流电源的极性。正接法指工件接正极，焊带接负极；反接法与此相反。

3．7调整焊机机头，将机头沿水平方向对准焊缝；调节机头升降装置，使焊剂流出管的末端与工件的间隙取25—40mm为宜。

3．8对于埋弧焊，用电钮“O↓O”将带极端头移动，到距工件5mm处选择机头运行方向“←→”。

4、堆焊操作

4．1开启焊剂供给阀。

4．2当机头末端漏出焊剂时，将红色开关调至“I”位置，直到起弧。

4．3堆焊过程中，仔细调整焊接参数（主要是焊接电流和电弧电压），焊接电流的粗调节可在电源箱上进行，细调节在操纵盘上进行。

5、堆焊结束

5．1将操纵盘上的开关旋至“O”位。

5．2关闭焊剂供给阀。

5．3若两次焊接过程之间的间隔时间很长，则应关闭电源，对于MIG/MAG焊，应关闭保护气体和水的供给。

5．4堆焊结束后，操作者要清理现场，做好设备维护保养工作。
