Welding positioners are a device that holds and turns a workpiece in order so that welders can work at an appropriate angle and on a uniform surface. It can move at a rapid speed even when it is carrying weights that signify weight. The principal function of a welder’s positioner is to ensure that the piece of work is always in the correct position for welding.
It can help reduce fatigue since they can stand in a single position and complete their work. They don’t have to bend or move since the welding positioner can rotate around 360 degrees. The object or the workpiece to be welded can be adjusted to the weld positioning device. Weld positioners can be fitted with pipes or valves. This is the primary reason they find many applications in industries that employ CNC machining or fabrication of metal to create metal components or parts. This article discusses the functions, benefits, and uses of weld positioners and others.
The basic principle that drives welding positioners is identical for any workpiece, large or small. They are a kind of plane of rotation that runs perpendicularly to the ground. It is possible to place huge tools on these tabletops. But a weld positioning device is much more than an axis that rotates. Its performance is contingent on limitations on the output of static torque. It can spin at breakneck speeds while carrying a substantial volume of weight.
Points to Know When Working on Weld Positioners
Here are some tips that workers must remember when welding using a weld positioner:
Examining your center of gravity (CoG)
The center of gravity is where the weight of an item is placed. When you choose the position weld, it is essential to think about your center of gravity for the workpiece and its weight and size. This will ensure the importance of the workpiece across all axes and affect the speed of the table’s rotation. CoG can change as the welder adds components with different weights and sizes to the positioning device. This is also something that needs to be taken into consideration.
Proper attaching of workpiece
The method by which the piece of work is secured to the welding positioner is essential as it is the method if it breaks off after the work is complete. Specific tasks that require repeating to make parts used in typical applications utilize specific production fixtures. In addition, for round-shaped workpieces generally, a three-jaw tool could be used for attachment to the positioning device. Some workpieces require bolts, which must be planned out according to the size and shape of the piece.
Flat, even surface
Make sure the whole device is mounted on an even, flat surface. Otherwise, the piece could fall off, which could pose a risk. It is possible to mount the positioner vertically on a table or a stand, however, it should be adequately secured.
A Few Reasons to Use Welding Positioners
There are numerous benefits to weld positioning devices, aside from the enhanced comfort of the person using them. Here are a few:
Better quality A welding positioner increases accuracy, and this implies that there are fewer chances of errors by workers.
Safety of workers A welding positioner guarantees the safety of workers. This is because the piece being welded is adequately secured in the positioner to ensure that it is not moved. As opposed to anchoring the workpiece by chaining the essay or tying it, there is the possibility of uncontrolled movement that could be risky.
Reducing fatigue Its design welding positioner allows workers to sit in one place and work, and it can be adjusted to their height and comfort level. Therefore their strain or fatigue will decrease and will help increase productivity.
Compact footprint Weld positioning devices can be adjusted to fit in small spaces, and this can reduce the amount of clutter on the floor of production.
Semi-automatic operation Weld positioners can be utilized as a semi-automatic device by connecting it to a power source. This increases the speed and consequently the productivity of the welder.
Positioners Increase Welding Throughput
Positioners boost productivity since they eliminate wasted time across a range of aspects. The first is that welding positioners allow for a maximum arc time. Chains, cranes and other rigging equipment require lots of effort to move, and frequently welders have to wait until the piece of work is properly positioned. This could have occurred multiple times in one welding.
The use of positioners allows the welder to move the part speedily! In the case of significant factors, the positioners permit one person to do the task without having to remove several people from the component. This results in labor savings and frees workers to do other jobs.
Positioners Improve Weld Quality
The main benefit of having the proper weld positioner is that it produces consistently high-quality welds. Any movement in the component in the welding process can make it difficult to create high-quality welds if your material is secure enough to allow for sufficient welding penetration. It is also simpler to complete the weld without shifting interruptions. Welding positioners can solve numerous issues related to the quality of the weld because it rotates the workpiece at a controlled rate and speed, ensuring continuous, penetrative welding.
Retrain & Attract Skilled Welders
With the welding workforce becoming a bit dwindling, retaining and attracting skilled professionals is an enormous advantage for any company. Positioners enable welders to work more efficiently, for more extended periods and more quickly. This equipment can improve the working environment, making it much more appealing to skilled workers. Positioners for welding additionally:
Enhance morale of employees
Utilize semi-automatic functions to reduce the fatigue of workers and boost production speeds.
What are the Different Applications of Weld Positioners?
Weld positioners are widely used in a variety of industries in which welding, and fabrication are needed. Here are a few applications of weld positioners:
- Rotor position
- The rotation of components for assembly
- The mounting of equipment for welding
- Welding of wheels, shafts, pipes, shafts, and more
- Large offset loads
If you’re searching for weld positioning devices for your industrial project, make sure you purchase the right producer and distributor. Woodward Fab is one of the most prominent makers and suppliers of sheet metal fabrication equipment. Weld positioners are offered by the company with different specifications that can satisfy customers’ requirements.
Utilizing manipulators, positioners, and the best way to use them
The manipulators and the positioners are alike; however, they differ in how the workpiece is placed. Positioners hold the workpiece while a manipulator can move and hold the welding heads.
The process of using a positioner to weld begins with the mounting of a workpiece on the plate. Then, it is clamped into place. In certain situations, investing in fixturing designed explicitly for this purpose is worthwhile.
The 3-jaw chuck design of work holding is a different option. A gear drive and motor will then turn on the face plate or chuck to place the workpiece in the direction the welder demands.
Tilt actions increase the positioning options available. The tilt of the faceplate can be made possible by the worm drive, which can be either motor driven or operated manually.
Positioners with two axes (or tilt/turn, tilt/rotate or tilt/turn positioners) allow for various ways to manipulate workpieces both on horizontal and vertical Axes. They are suitable for pipe applications, such as elbows and flanges. Welding turntables are used for projects where the workpiece must rotate around the vertical axis.
Turning roll is a good choice for larger or heavier work like pressure vessels or tanks. Headstocks/tailstocks are for rotating a workpiece around a horizontal axis, and the headstock by itself could be sufficient to rotate smaller workpieces horizontally. The larger and more heavy workpieces will require the addition of an additional tailstock.
