深海脐带缆内套钢管全位置脉冲TIG对接焊研究
Research on Full Position Pulse TIG Butt Welding of Steel Pipes in Deep-sea Umbilical Cable
摘要
Abstract
The deep sea umbilical cable is the lifeline for connecting the topside control facilities and the undersea production system;the quality of each steel pipe in umbilical cable which consists of tens to hundreds of steel pipe butt welding must be impeccable. Because the particularity exists in tube-tube butt welding, the welding defects occur easily in welding course, which seriously affects the working performance of umbilical cable. Through a large number of tests, during precision group for each 12 m to 40 m steel pipe, the circumferential weld of small diameter steel pipe of unable to rotate was welded by full position pulse TIG welding process. It determined the best welding procedure specification parameters, and obtained perfect welded joints with good weld profile, good penetrability and excellent quality.关键词
