影响压力钢管对接焊缝质量因素分析

Analysis of factors affecting butt weld quality of pressure steel pipe

压力钢管的焊接过程决定着压力钢管的最终质量,焊接过程中人的因素最为重要。结合前坪水库输水洞电站右岸压力钢管现场安装,主要分析压力钢管从安装到焊接环节对焊缝质量的控制措施及影响因素。专业技术管理人员和施工操作人员必须提高自身素质,在施工中加强事前、事中质量控制,事后质量检测,增强业务水平,提高一次焊接合格率。

The process of soldering pressure steel pipe plays a big part in pressure steel pipe’s final quality.What’s the most important is human factors.Combined with the on-site installation process of the right bank pressure steel pipe of Qianping Reservoir water transmission tunnel power station,this paper mainly introduces the analysis of the quality control measures and influence factors of the butt weld from installation to welding of the pressure steel pipe during the on-site construction.Professional technical managers and construction operators must improve their own quality.They should enhance beforehand and process control,final quality detection,professional skills and increase first pass yield.
