摘要

目前核电站建造阶段管道全位置仍以手工焊为主，存在着焊接效率低，焊接质量参差不齐，管道自动焊接的推广和应用已变得尤为迫切。为此，自主研发了一套核电站管道全位置TIG自动焊接控制系统。系统从硬件系统和软件系统出发，以STM32单片机为控制核心，以焊机通讯单元、电机驱动单元及触摸屏等为实施载体，完成主控制程序、自动焊逻辑程序和UI界面的设计。该系统已经设计并验证完成，与自动焊机设备融合度高、性能稳定可靠，操作简单。并在核工程管道焊接中进行了推广应用，可有效提升焊接效率和焊接质量，降低自动焊设备的采购成本。同时该设备系统可扩展应用于其他行业的管道自动焊接中。

Abstract

At present, manual welding is still the main method for all positions of pipelines in the construction stage of nuclear power plants, and there are some problems such as low welding efficiency, uneven welding quality, etc. Therefore, the popularization and use of automatic welding of pipelines has become particularly urgent. In view of above problems, an all-position TIG automatic welding system for pipelines is independently developed. Starting from the hardware system and software system, the STM32 single chip microcomputer is taken as the control core, and the communication unit of welding machine, motor drive unit and touch screen are used as the implementation carriers to complete the design of main control program, automatic welding logic program and UI interface. This system has been designed and verified, with high integration with automatic welding equipment, stable and reliable performance and simple operation. It has been widely used in nuclear engineering pipeline welding, which can effectively improve the welding efficiency and quality and reduce the procurement cost of automatic welding equipment. At the same time, this system can be applied to automatic welding of pipelines in other industries.
