锅炉管爆漏修复自动焊控制策略及试验结果

Control strategy and test results of auto welding for repairing ruptured boiler tubes

针对电厂锅炉管爆漏的修复问颗。开发了一种能对管间距大于45mm、管直径小于60mm的锅炉管进行自动焊的焊机机头,并用PLC进行控制,使之能全自动焊接。文中介绍此焊接系统的组成、控制策略及工艺试验结果。

In order to resolve the problem of repairing the ruptured utility boiler tubes, a welding head is developed, which can be usedfor welding the ruptured tubes with diameter less than 60 mm and space between tubes bigger than 45 mm, and can be operated attomaticallywhile being controlled by PLC. The paper briefs the composition of welding system, control strategy and test results.
