Development and Application of Open Automatic Welding Equipment with Molten Pool Monitoring Function
摘要
Abstract
To address the challenges of significant welding quality fluctuations and high welder labor intensity in pipeline en-gineering for nuclear power,petrochemical,and other industries,caused by the lack of effective molten pool visualization methods in traditional open automatic welding equipment,a new type of open automatic welding equipment suitable for on-site construction,equipped with real-time molten pool monitoring function,has been developed.An integrated monitoring system was constructed by customizing domestically produced small molten pool monitoring cameras,optimizing the weld-ing torch structure and welding head layout,and integrating wireless transmission modules.Core technologies include:adopting a quartz glass nozzle and a 45° bent design for water,gas,and electrical lines,reducing the obstruction rate of the molten pool observation line of sight from＞75%to＜15%;achieving end-to-end transmission delay＜80 ms based on 5.0 GHz Wi-Fi technology,with strong resistance to arc light and electromagnetic interference;ensuring equipment adaptability in confined spaces through a modular and compact design.Validated by welding process tests and large-scale on-site applica-tions in the nuclear power industry,this equipment enables clear real-time monitoring of the molten pool status.The result-ing welds exhibit good formation without defects such as lack of fusion or porosity,achieving a first-pass yield rate of≥98%,while significantly reducing the labor intensity for welders.This equipment achieves localization replacement of core components,breaking foreign technological restrictions.It not only provides a safe,efficient,and independently controllable welding solution for high-end manufacturing industries like nuclear power and petrochemicals,safeguarding nuclear safety and national energy security,but also promotes a leapfrog upgrade of China's open automatic welding equipment from"auto-mation"to"visualization+automation,"establishing a competitive advantage for domestic high-end welding equipment in core technological fields.关键词
