ABSTRACT:
The invention comprises an apparatus for aligning and guiding the seam of newly formed tube as it enters the welding mechanism in the manufacture of continuous seam-welded metal tubes or pipes. A rotary seam guide member having an alignment fin is mounted so that a alignment fin rollingly engages within the open seam immediately in advance of the seam welding mechanism. The seam guide member and a cooperating opposed roller guide the tube into the welding mechanism. The seam guide and opposed roller are carried within a roll stand including mechanism by which their position may be adjusted vertically and longitudinally relative to the welding mechanism, as well as rotated arcuately about the path of the tube. The seam guide member and/or the opposed roller may include insulating barriers to impede induced heating thereof.
