Abstract
Extensive use of circumferential gas tungsten arc (GT A) welding in industrial applications has been handicapped due to the difficulty of choosing the optimal process parameters. In Part 2 of this study, the welding current and backing gas pressure are optimized by calculating the three-dimensional transient temperature distribution and the surface profile of the resultant weld pool in circumferential GTA welding of small-diameter pipes, in order to obtain a uniform weld bead without any hang-down over the entire circumference of pipes.
