摘要
Abstract
In large-scale water conservancy projects,the use of steel pipes for hard rock roof pipes is becoming increasingly common.The welding and inspection of butt welds during the construction process of top pipe steel pipes account for a large proportion of the time,and the quality and efficiency of welding directly affect the construction progress of the top pipe.Based on the subsequent optimization project of Hanjiang Rongjiang Lianjiang water system connection,this paper analyzes the influence of different sizes and types of K-groove on the welding quality and efficiency of hard rock top pipe steel pipe butt welds,summarizes the groove sizes used,and provides suggestions and opinions for the welding of top pipe steel pipes.关键词
