girth welding（环向焊接）是管道工程中沿圆周方向连接两段管道的焊接工艺，属于管道安装的核心技术之一。其名称中的“girth”指环形或周向形态，“welding”即焊接，组合后特指在圆柱形工件（如管道、储罐）的圆周方向进行的对接焊。
该工艺需严格遵循以下要求：
国际焊接学会（IIW）及美国焊接协会（AWS）均将环向焊接列为管道安全的核心技术，相关规范可参考《焊接与连接工程手册》（Welding and Joining Engineering）。
“Girth welding”是焊接领域的技术术语，其含义和用法可综合解释如下：
如需进一步了解具体焊接参数或标准，可参考行业规范（如ASME标准）或专业焊接手册。
