The results indicate that the groove dimensions must be optimized and the rational welding sequence must be adopted, namely, the large groove side should be welded at first for the non-symmetrical X-type groove, and the proper angular distortion must be pre-setup according to different plate thickness for decreasing the welding deformation influenced by the deadweight of steel plates. For the butt-welding of thick plates, the transverse deformation will increase linearly and the longitudinal deformation which is proportional to the weld area will decrease and the angular distortion will decrease exponentially with the increase of steel plate thickness.
