Design Sketch of Cross Slides Welding Manipulator

Below is design illustration on a set of Wuxi JACK LHZ4040 Moving Welding Manipulator:

1. The largest diameter of tanks/ pipes that can be welded in this Pipe Tank Welding Machine is 4000mm;
2. Length of traveling rails is based on required length of workpiece;
3. During running of the Welding Manipulator, workpiece is laid onto 2 sets of Welding Rotator;
4. Welding mode is flexible based on process technology at working site.

Welding Head in LHZ Series Cross Slides Welding Manipulator

1. All the kinds of welding modes can be adopted in the LHZ series Welding Manipulator, which is realized by means of configuration and set-up way of its welding heads;

2. The above 4 photos reflect on the 4 common seen welding modes and corresponding welding heads used in Cross Slides Welding Manipulator:

1) Large current SAW (Submerged arc welding) for welding thick wall pipes/ tubes/ tanks that are made of carbon steel;
2) Delicate TIG (Tungsten Inert Gas) welding for fabricating thin wall stainless pipes/ tubes;
3) High IK value CO2 GMAW for fabricating small to Strong intensity medium thickness workpiece in Welding Manipulator;
4) Strip Cladding (Hard facing) for building up a layer of anti-corrosion on surface of workpiece, in this Pipe Tank Welding Machine;

3. Correspondingly, from the above 4 photos, we can see that, welding head of the Cross Slides Welding Manipulator has main elements of:

1) Various modes of Welding torch, its position controlling mechanism, including high precision cross slides, or seam tracker;
2) Welding wire feeder, and wire reel;
3) SAW welding flux hopper, recycling unit, and conveying tubes;
4) Control console of welding power supply, and seam tracker, that conforming to welding modes adopted in specific Cross Slides Welding Manipulator;

4. Welding Modes of Welding Manipulator Linkage with Corresponding Product Section:

Outsourced Function Cells of Cross Slides Welding Manipulator

In daily operation of Welding Manipulator, to meet the personalized demand from customers, there are series of outsourced function cells available, to be equipped in this tube pipe Welding Equipment:
1) Seam Tracker for managing welding torch;
2) Video graphic monitor for internal welding inside tubes/ pipes;
3) Welding swing for getting wider welding seam...

Seam Tracker in Welding Torches of Various Welding Equipment

1. Seam Tracker is a necessary function cell for realizing high standard welding, in nearly all the kinds of Welding Equipment. It forms a closed loop circuit for managing welding torch, during the entire working period of Welding Manipulator;
2. Working principle of seam tracker is like this: It collects real time position data of welding torch, making calculation, then sending command in the form of displacement, making welding torch tracing accurately along welding seam all the while, in LHZ Pipe Tank Welding Machine;

3. Installation illustration of seam tracker onto welding torch in Welding Equipment:

Fig1 Welding Equipment 149

4. Complement on Adoption of the Seam Tracker in Welding Manipulator:

1) The seam tracker is a very powerful tool for guaranteeing welding quality of the LHZ automatic high precision Welding Manipulator;
2) On the other hand, the performance of the whole set of equipment depends on coordination of all the units of the Moving Welding Manipulator.

Video Graphic Monitor in Cross Slides Welding Manipulator

1. When the Welding Manipulator is used for internal welding of cylindrical workpieces, for performing longitudinal and or circumferential welding, such operation belongs to blind welding;
2. To have well placed control on the welding process in the Pipe Tank Welding Machine, an external surveillance unit of video graphic monitor should be used;

3. Video Graphic Monitor is used for checking welding condition, on internal welding in the Cross Slides Welding Manipulator: 

Fig1 Welding Manipulator 141  Fig2 Welding Manipulator 142
1) As can be found from the above photos, in the case of internal welding inside cylindrical parts with the Cross Slides Welding Manipulator, especially for small diameter workpieces, it is hard and dangerous for people to have direct access on the welding torch;
2) By this time, video graphic monitor is a hit for managing welding process happened in the Welding Equipment of Integral Control Welding Manipulator;
3) With the help of this function unit, operators of the Welding Manipulator can track condition of internal welding inside cylinders/ tanks in real time manner, controlling the welding process of the Welding Manipulator precisely and accurately.
