摘要

环形焊缝是管道、容器、化工设备等生产中常见的一类焊缝

因其焊接位置复杂、人工焊接可达性差、焊接难度大等特点

在实际生产中常采用各种形式的自动环缝焊机来代替人工焊接。但目前常见的自动环缝焊机仍然存在诸如生产效率低、适应面窄等问题。根据实际生产的需要

对普通变位机和气保焊机进行改造

通过PLC自动控制功能同时控制多把焊枪

实现了自动高效的环形焊缝焊接

该系统结构简单、生产效率高、功能强大

尤其适用于同轴多道环形焊缝的焊接。

Abstract

Ring welds are a kind of welds commonly used in the production of pipes

containers

chemical equipment

etc. Due to their many welding positions

poor accessibility of manual welding and difficulty in welding

various forms of automatic ring seams are often used in actual production. The welder replaces manual welding. However

the current automatic seam welder still has problems such as low production efficiency and narrow adaptability. According to the actual production needs

this paper uses ordinary positioner and the most common gas shielded welder to transform. Through the powerful automatic control function of PLC

multiple torches are controlled at the same time

which realizes automatic and efficient ring weld welding. The system is simple in structure. High production efficiency and powerful function

especially suitable for the welding of coaxial multi-channel annular welds.
