Weld positioning devices or welding positioners are machines that usually have rotating parts for easy access to welding operations on odd-shaped parts. While some devices allow 360 degrees of rotation, other accessory tools are height-adjustable.
Most manual welding machines require repositioning of weld materials into a more comfortable range or may force the welders to operate in restricted or uncomfortable movement that doesn’t support the necessary range to complete a job.
On the other hand a welding positioner allows the operator to stay in one position, synchronized to remain level, and thereby, preventing worker fatigue. In most cases, a single person can operate these machines. This method provides high-quality welds as vertical welding is not necessary which increases productivity. Weld positioning equipment is not only ideal for welding large assemblies, but can also be used on smaller projects.
Benefits Provided by Welding Positioners
Without a welding positioner, some joints may be required to be welded out of position. This can cause several issues. One being weld quality, since it is generally more difficult to make a satisfactory weld out of position than in a flat or static position. The other concern is worker fatigue. Welding positioners can hold workpieces of many different shapes, sizes, and weights and put them in the most ergonomic position for a worker. Welding positioners also increase efficiency by reducing the required amount of worker movement. Welding positioners are generally used for objects that are too heavy to rotate and move by hand.
- Reduced welder fatigue
- Higher weld quality and precision
- Easy weld process on complex jobs
- Speedy operations
- Increased productivity
- Wide range of capabilities
- Improved workshop safety
- Less production floor space
- Better accessibility of the weld materials
- Reduced rejection rates
- Maximum weld deposition rates
Working Principle Of Welding Positioners
Irrespective of the size of the project, welding positioners function on the same working principle. The operator affixes the base product or workpiece onto the welding positioner using clamps or bolts.
As the device grips it securely in a flat position, the welder can mechanically change its position to an orientation that allows them full access to the weld joints, from a more comfortable position. Sub-assemblies or parts can be added without any break in the process and without requiring complex maneuvers to hold the welding torch.
Types of Welding Positioners
Red-D-Arc offers a wide range of weld automation equipment, including welding positioners, available for sale, rent, and lease.There are three main types of weld positioning equipment:
These machines can be operated using manual hand cranks, or foot pedals to move the weldment in the desired direction at the right speed.
A welding positioner that works in combination with additional equipment to achieve improved productivity. For example, accessories like a torch stand can be fitted to the positioner to get the welding done under a stationary torch.
For jobs requiring higher weld precision and repeatability, weld positioners can make use of robotics. Automatic welding stations are suitable to produce large quantities of weldments.
General welding positioners refer to those devices that allow for full 360-degree rotation of the workpieces for welding. Depending on the weld function, others are classified as follows:
Rotary Welding Positioners
For precision welding applications on circular objects, operators make use of rotary weld positioners. Using a variable speed control box, in addition to an optional variable-speed pedal, you can set the accurate speed.
Pipe Welding Positioners
A pipe welding positioner enhances productivity while working on large offset loads - mainly pipes, elbows, shafts, wheels, and others. Their varied applications range from pipe spooling to the positioning of complex workpieces such as chassis components.
Headstock & Tailstock Positioners
Long rectangular components, which have to be supported from both ends, can be welded using headstock tailstock weld positioners. They provide maximum flexibility when rotating massive workpieces like trailer frames.
Gripper Welding Chucks
Gripper welding chucks are specialized clamps used to secure customized metal pieces to be welded to the headstock or tailstock. These machines can increase efficiency and are designed to withstand the robust working conditions of the welding industry.
Weld turntables are high-precision, low-cost devices that provide workpiece positioning in the horizontal position. They allow for rotation of industrial workpieces such as pipes or vessels around a vertical axis. Primary applications of floor welding turntables are welding, X-ray and machining, and flame cutting operations.
Proper Usage of a Welding Positioner
When using a welding positioner, whether it is a floor or benchtop weld positioner, safety should be the first consideration. The welding table should be secured to a stable surface, making sure that it stays in a horizontal position. In addition to clamping the workpiece, quality tack welds provide some rigidity and oppose the weld stresses and prevent the edges of the joints from being displaced. The stationary torch has to be fixed to an adjustable clamp.
During the welding process, the weld positioning equipment has to be connected to a ground current to avoid damage to the electrical parts. It is critical to use the welding positioners as per the manufacturer’s specifications. Spec sheets and manuals about the size, load, speed requirements, and which operations they can handle should be consulted before beginning welding operations.
