Abstract
A method for forming a large-diameter special-shaped cross section thin-wall tubular part. A tailor welded barrel blank is adopted as an original blank for forming of the large-diameter special-shaped cross section thin-wall tubular part. After a desired shape is formed, the original weld joint is removed and butt joint tailor welding is performed on the tubular part again. Since the tailor weld joint of the original barrel blank is removed from the final part, there is no need to consider the consistency or coordination of the microstructure of the weld joint and the base metal during the forming process and the subsequent thermal treatment process.
