Yoder Seam Rotation Stands (SRS), or seam orientation unit (SOU), is a unique device, which allows the mill operator to locate and position the weld seam at a particular radial location. In the event of cambered strip or seam wandering it is now possible to place the seam at the twelve o’clock (12:00) position, or wherever the operator chooses to place it in a sixty-degree (60°) axis from top dead center. The Seam Rotation Stand can be supplied with manual adjustment or motorized adjustment. Common Structural sizes include 3.5″ (89.2 mm), 5.5″ (139.7 mm), 6-5/8″ (168.3 mm), 8-5/8″ (219.1 mm) for mechanical tubing and hollow structural sections.
