The effect of thickness proportional allocation of the K type groove on the local deformation was  compared, which was directly related to the volumetric shrinkage in each welding pass. The result showed that when the groove angle is 55° and the thickness proportion between the upper and the lower parts is 3:2, the weld-ing distortion is acceptable with minimum consumable welding electrode cost and high working efficiency. The simulation stress distribution curves are consistent with experimental data by the hole-drilling method.KEYWORDS: high strength steel, groove angle, tubular weldment
