LHZ Versatile Electric And Automatic Welding Manipulator for Industry

1. Outline on Classification and Configuration of General Purpose Welding Column and Boom:

LHZ series General Purpose Welding Manipulator can be divided into 2 general groups of standard and Special Made types, which can be further classified from below aspects:

1) Structure: Static and or motor drive moving structure, with Column Non-revolving, or Manual/ Motor drive Revolving;

2) Loading capacity: Light duty /Medium duty /Heavy duty automatic models;

3) Design and Configuration: General purpose / Special made;

4) Purpose: For tank welding/ pipe/tube fabrication automatic models;

5) Welding Mode: SAW (Submerged arc welding)/ GMAW (Gas Metal Arc Welding) /MIG/ TIG/ MAG/ ESW (Electroslag) /Strip Cladding;

6) Working Manner: Individual set of universal Column and Boom welding machinery, or Welding Center;

7) Chain of dedicated optional supplementary units: Welding seam tracker/ Video monitor/ Oscillator/ Cross slide.. available for choices to be equipped into Universal Welding Manipulator: Welding seam tracker unit installed onto welding head: (Fig.1) 

  Video monitor when operator difficult to have direct access on welding point: (Fig.2)

The above mentioned perspective can be permutated and combined to form into dedicated product of Special Made Welding Manipulator.

2. Welding Power Supply Equipped in General Purpose Welding Manipulator:

There are several brands of welding power source and supporting units under the scenario of various welding mode:

1) Chinese HUAYUAN /U.S. Lincoln/ Swedish ESAB for SAW;

2) Chinese HUAYUAN/ Japan Panasonic for GMAW (Gas shielded welding: MIG/ TIG/ MAG/ CO₂);

3) Swedish ESAB for Strip Surfacing (or Strip Cladding)

3. Outline on Working Manner of LHZ Automatic Welding Column and Boom:

1) Boom horizontal movement leftward and rightward, which is for performing welding job, is powered with A.C. braking motor, and has speed controllable by means of A.C. inverter and displayed, on operating pendant of the automatic manipulator welding machine: 

Motor, gear and rack for driving and transmission Boom movement: (Fig.3)

2) Horizontal Boom elevating movement, column revolve and trolley travel are also powered with A.C. braking motor in constant speed;

3) All the above mentioned movement are constant torque delivery;

4) Start on and or stop operation of Welding Manipulator is quick and nimble;

5) Slewing support (or called Cross roll bearing) of the Universal Welding Column and Boom is made from Chinese domestic professional and famous supplier. It is fit with high precision gear, featuring in flexible rotation and dependable running, and can be locked securely by hand:

6) Motor drive moving trolley rail of the moving structure models Manipulator Welding Machine is standard type railway track. Trolley has two types of manual and motor drive. Of which manual trolley is usually for light duty and or small movement range of Column and Boom Welding equipment, while motor drive trolley is for medium and heavy duty models, and or extensive traveling range;

7) Manned type Special Made Welding Manipulator is equipped with chair or platform, alongside the boom;

8) Electric Control: With the help of remote pendant and operating panel, both direct and remote control can be realized in LHZ automatic Column and Boom welding machinery, with convenient and easy operation;

9) Future Expansion: There is open interconnecting interface inside control cabinet of the Standard Welding Manipulator, for the convenience of future synchronous linkage with other kinds of Welding Equipment, such as Welding Positioner, Welding Turntable, Welding Rotator, etc.;

10) Safety Mechanisms: Besides these versatile and powerful function, LHZ series universal Column and Boom manipulator Welding machine has complete set of safety units. Please check product section of “Industrial Use Column and Boom Welding equipment”, making sure the Manipulator Welding machine delivering good quality welding seam, in safe, reliable, and consistent manner.
