深圳市天然气高压输配系统工程焊接工艺优化的研究

摘要

文章主要介绍了对焊接工艺技术优化的研究,根据环境气候、地理区域的不同,在高压输配系统工程中,适当调整管道焊接工艺参数,即提高焊道预热温度、提高焊道过程中的层间温度、改变焊道坡口尺寸,可以提高焊接质量和焊接效率。%The paper introduced the climate,according to different geographical area,and adjust the pipe welding process parameters,namely,increasing the welds temperature,temperature,between layers change welds groove size could improve the quality of welding and welding efficiency.
