PR-series Electric Variable Speed Universal Pipe Rotator for Welding

1. Usage of PR Series Electric Pipe Welding Rotator:

1) Applicable Workpieces: PR series Electric Pipe Welding Rotator is for welding small and light to medium cylindrical parts and flanges, such as pipe, tube, elbow of various specifications;

2) By means of 0°~360° turning and -45°~+45° tilting of Turning Roller, the workpiece can be adjusted to the best orientation for optimum way of welding. Examples of applicable workpieces for this electric Pipe Welding Positioner see below sketch: 

Design Sketch of workpiece Pipe elbow: (Fig.1)

2. Working Nature of PR Series Electric Pipe Welding Positioner:

Looking at attached photos of this product, you can draw conclusion that it is integration of Special Made Welding Rotator and Special Made Welding Positioner:

1) These welding equipment product has typical working style of conventional stand single work table models: Turning Roller and workpiece 0°~360° turning and -45°~+45° tilting;

2) These Electric Pipe Welding Rotator also has typical working style of Welding Rotator: Workpiece 0°~360° turning on the two groups of Turning Roller.

3. Application and Strong Points of PR Series Electric Pipe Welding Positioner:

1) Application of Electric Pipe Welding Positioner:

As to its application, this electric Pipe Welding Rotator can be used in facilities involving certain amount of pipe, tube, and elbow welding, in both manual and automatic circumferential welding. Especially at shipbuilding plant;

2) Advantages of Electric Pipe Welding Positioner:

a) Overall Dimension: This welding equipment product has strong points of compact design and easy handling. As you can identify from its photos, this upright model takes very small size of land occupation;

b) Constructure: This Electric Pipe Welding Positioner is integral structure, no need to have foundation made ahead of time. Just secure it into ground with anchor bolts;

c) This compact welding rotating equipment has advantages of easy and user friendly operation. It can relieve labor intensity, and improve welding quality to a great extent.

4. Technical Features of PR Series Electric Pipe Welding Positioner:

1)  The entire working process is motor driven;

2) During working period, workpieces of pipe, tube, workpiece pipe elbow should be put on table top Turning Roller of the welding rotating equipment, supported and turned with 2 groups of bottom Turning Roller at its beneath, and held firmly with another piece of top Turning Roller above it. See below picture:

5. Three Degrees of Freedom in PR Series Pipe Welding Rotator:

From its structure can be seen, that this Pipe Welding Positioner has three motion control axis, or degrees of freedom:

1) Pipe, Tube, Elbow axial revolve, speed adjustable with a.c. inverter, within the range of 0°~ 360° , also the actual welding speed;

2) Pipe, Tube, Elbow radial tilt, or swing, in constant speed, within the range of -45°~+45°;

3) The top pressing Turning Roller downward movement, catering for different diameters of workpiece, in constant speed, with both motor drive and manual control of two options.

6. Standard Models of PR Series Electric Pipe Welding Positioner:

1) This variable speed Electric Pipe Welding Rotator has two standard models of PR24 and PR40 Turning Roller, for welding small to medium size, and medium to large sizes of pipe, tube, elbow respectively;

2) For this PR series product group, we will give instruction in the four product sections, covering detailed model and general group;

3) From next product of PR24 model, we will have deep down exploration on structure, parameters, and performance of the pipe welding rotator.
