摘要
为了解决大口径管道施工中环焊缝根焊的效率和质量问题,采用管道内环缝多焊炬自动焊机可以实现这一目的。国产数控式管道内环缝多焊炬自动焊机采用以CPLD可编程逻辑器件为核心的全数字控制技术,有效地实现了整机的定位、对口、焊接、自动行走等一系列动作的自动化控制。通过大量的内焊试验,制定了合理的内焊工艺。现场应用表明,国产数控式管道内环缝多焊炬自动焊机整机结构合理、控制先进、操作简便,焊出的内焊缝符合工程检验标准和规范。
For resolving the questions of welding speed and quality in course of large diameter pipeline construction, internal circumferential automatic welding machine with muhi-torches can be utilized for this goal.Internal circumferential automatic welding machine with multi-torches made in China may carry effectively on automatic controlling of localization,alignment,welding,automatic movement and so on,based on the key technologies of CPLD programmable logic processor.The reasonable inner welding process has been established according to a lots of welding tests.The field application indicated that the domestic, numerical control internal circumferential automatic welding machine with multi-torches has reasonable structure,advanced control easy to operate.The inner welded joint welded by it has been in compliance with the project inspection standards and the related roles.
