CONVENTIONAL WELDING ROTATORS
FREQUENTLY ASKED QUESTIONS [FAQ]
1. What is the advantage of Conventional Welding Rotators? They have the same load and rotation Capacity on all their vessel diameter ranges. A disadvantage of Self-Aligned Welding Rotators: The load capacity reduces when the vessel sits only on the bottom wheels of the roller
2. What is the advantage of Self-Aligned Welding Rotators? They adjust to vessel diameters within the Roller’s Self-Adjusted Zone, avoiding downtime. SAR rollers also provide better weight distribution due to their eight wheels. A disadvantage of conventional welding rotators is that the distance between wheels (center to center) is manually adjusted using nuts and bolts, resulting in downtime whenever the vessel diameter changes. A re-torque is required.
3. How do you select a Welding Rotator for a workpiece with concentric loads? Select a welding rotator that fits the load and rotation capacity of the rollers. The workpiece must have at most 30 m in length.
4. How do you select a Welding Rotator for a workpiece with eccentric loads? Add a counterbalance or contact Irizar technicians; they will assist you in choosing the appropriate welding rotator for your application.
5. How do you rotate a workpiece from 30 to 60 m? Use two power rotators and a synchronized device.
6. How do we increase load and rotation capacity? Increase load and rotation capacity by 100% by adding an extra set (power rotator & idler rotator) and a synchronized device. It is valid only if the workpiece does not exceed the roller's capacity.
KNOWLEDGE BASE [KB]
Welding Rotators are also known as Tank Rollers, Welding Rollers, Tank Rotators, Weld Rotators, Pipe Rotators, Welding Rolls, Welding Rotators, Vessel Rollers, Tank Rolls, Welding Tank Turning Rolls, Turning Rolls, Rotador de Soldadura, Virador de Soldadura, Virador de Tanques, Rotador de Tanques and Rotador de Tuberia.
Welding Rotators are specialized pieces of equipment used in the welding and fabrication industry. They are designed to support and rotate cylindrical workpieces, such as tanks, pipes, or vessels, during welding, assembly, or maintenance processes. Its primary purpose is to provide a controlled and efficient method for manipulating large and heavy cylindrical objects, enabling precise welding or fabrication work. Key features and components of Tank Turning Rolls include:
Wheels: Tank Turning Rolls typically consist of two sets of roller wheels (power rotator & idler) arranged in a bed configuration. The workpiece is placed on these rollers, which facilitate smooth rotation at variable speeds.
Adjustable Configuration: The distance between the rollers can be adjusted by bolts and nuts to accommodate different diameters of cylindrical workpieces. This adjustability ensures a secure and stable support for various sizes of tanks or pipes.
Rotation Control: Tank Turning Rolls come with a mechanism to control the rotation speed of the workpiece. This is essential for achieving uniform and high-quality welds. The rotation speed can be adjusted based on the specific requirements of the welding process.
Drive System: These systems are equipped with a drive mechanism that powers the rotation of the rollers. The drive system is motorized, allowing for both forward and reverse rotations.
Control Panel: The Tank Turning Rolls remote control box allows operators to set and monitor the rotation speed.
Heavy-Duty Construction: Due to the nature of their applications, Tank Turning Rolls are built to withstand the weight and stress of large cylindrical workpieces.
The use of Tank Turning Rolls provides several advantages, including increased efficiency, improved weld quality, and a safer working environment for welders. These devices are commonly employed in industries such as oil and gas, petrochemical, shipbuilding, and construction, where the fabrication of large cylindrical tanks is a common practice.
Irizar Heavy Industries manufactures models from 3 MT to 2,500 MT.
