抄録	In the paper, the thick-wall pipes of 304L stainless steel used in nuclear power station are circumferentially welded with an all-position narrow gap TIG welding machine and the transient welding distortions were automatically measured. Conclusions show that the axial welding distortion is strongly related with the filling of the weld groove and heat input, and the axial welding distortion occurs mainly in the two-thirds filler depth of the weld groove from the inner surface, while the axial distortion barely exists in the rest of the weld groove. As the heat input is critical to axial shrinkage, the axial shrinkage could be controlled by continuous welding with less heat input.
