A weld positioner rotates round or tubular workpieces to allow welders to work steadily on a flat surface, reducing fatigue and increasing productivity. It ensures consistently high-quality welds and allows for continuous and adequately penetrating welds. It is available in various sizes and can be electrically or pneumatic-hydraulically operated.
A weld positioner is a device that rotates round or tubular workpieces such as flanges and pipes 360 degrees to allow a welder to stand in one position and work steadily on a flat surface. This prevents worker fatigue and increases productivity as the welder does not need to constantly move around the pipe to complete the weld. This method of presenting the work piece also tends to ensure consistently high quality welds as no vertical or overhead passes are involved.
Joining pipes or connecting fittings such as flanges and valves is a challenging task from an execution point of view due to the 360 degree work plane. Without the use of a tool such as the weld locator, the craftsman may have to constantly move around and under the pipe to complete the joint, which is not conducive to a good quality weld. In particular, this is laborious, time consuming and requires vertical and overhead welding passes with frequent stops for repositioning.
A high quality arc weld seam requires adequate material penetration, level workpiece orientation, and carefully controlled weld speed with a minimum of stoppages. To obtain good arc penetration, the welder must work at the maximum amperage allowed by the welding rod or electrode. For this to be effective, the work piece must be leveled so that the pool of molten metal settles into the joint without sagging or pouring. This is the biggest problem with welding vertical or overhead runs where lower amperage settings are needed to keep the weld puddle from sagging. Proper weld speed and continuity of execution are also vital components of a good welded joint.
All these requirements are difficult to achieve with a static piece. A weld positioner solves all of these problems by rotating the workpiece at a constant, controllable speed. This allows the craftsman to stand in one position and work in a permanently level orientation. The weld positioner can also be controlled to rotate the work piece at exactly the right speed to maintain a continuous and adequately penetrating weld.
Finishing a circular joint in one operation reduces completion time and increases productivity. The welder can also sit or stand comfortably which reduces fatigue and allows for better concentration on achieving a perfect seam. A weld positioner can be electrically or pneumatic-hydraulically operated and is available in a variety of sizes to suit all applications.
