摘要： A method and apparatus for welding a first workpiece which is to be joined to a second workpiece, with said first workpiece extending within or through the second workpiece. The apparatus includes a rotatable workpiece drive member, a workpiece holding fixture for securing at least one other workpiece in position relative to the first workpiece and a radial support for the first workpiece that is separate and spaced from the drive member. Among the preferred embodiments disclosed for providing the radial support are a tailstock supporting sleeve arrangement, collet chucking, and roller type steady rests.

摘要： A method and apparatus for mechanically expanding pipe of the type having a helical weld seam which includes a radially expandable die head assembly for incrementally expanding the pipe advanced over the die head and wherein the die head has a helical groove which corresponds to the helical weld seam of the pipe. Means are provided for advancing the pipe longitudinally over the die head assembly for incremental expansion and preferably for substantially simultaneously rotating the pipe to maintain the conformity between the die head groove and the helical weld seam of the pipe.
摘要翻译：一种用于机械膨胀该类型的管的方法和装置，其具有螺旋焊缝，该管道包括可径向扩张的模头组件，用于逐渐扩展在模头上方的管，并且其中模头具有对应于螺旋焊缝的螺旋槽的管道。提供了用于将管道纵向推进在模头组件上用于增量膨胀的装置，并且优选地基本上同时旋转管道，以保持模头凹槽和管道的螺旋焊缝之间的一致性。
