The shrinkage distortions in welding are unavoidable trouble in welding procedure, and the complex problem for the welder.
When we build up the welding constructions, it is always interesting problem to intend to decrease these distortions.
If we want to solve this unavoidable, complex problem, we must first know the primary shrinkage distortion in welding. And so in this paper the shrinkage distortions in only one pass welding bead are described.
Distortions in welding are due to both shrinkage transverse and parallel to the direction of the weld. To consider the phenomena simply, we disregarded the effect of the distortion due to shrinkage parallel to the direction of the weld, and measured only the distortion due to the shrinkage transverse to the directiorn of the weld. We experimented two cases. Namely one case was done when the welding speed was constant and the welding current was changed, another case was done when the welding current was constant and the welding speed was changed.
