LHZ High Precision Automatic Welding Manipulator with Seam Tracing Unit

1.       The Importance and Benefit of Seam Tracker equipped in Welding Manipulator:

1)      Seam Tracker is an important supplementary unit equipped in various kinds of Welding Equipment including Welding Column and Boom, H Beam Fabrication Machine, and Pipe Welding Machine, etc.

2)      Purpose of the Seam Tracker is to tracing on actual position of welding torch during operation, and controlling on this position accordingly, so as to guarantee the consistent precise and accurate position of welding torch, in the whole working period of Welding Equipment;

3)      Please check attached the 2^nd photo on the seam tracker equipped in Automatic Column and Boom, and how does it fit onto a set of High Precision Automatic Welding Manipulator at working site: (Fig.1)

4)      Benefit of the Seam Tracker applied in Cross Slides Column and Boom:

a)       The Welding Manipulator with Seam Tracker is the “high-tech” product of Welding Equipment: Equipped with this optional seam tracing unit, the Automatic High Precision Welding Manipulator can fulfil various welding mode (SAW/ CO₂/TIG/MIG) on workpieces in designated accuracy, without human intervention in the welding process;

b)      Operator only needs to set parameters and validate it at the start-up of the Cross Slides Column and Boom.

2.       Technical Brief on LHC High Precision Automatic Welding Column and Boom with Seam Tracker:

1)      Purpose of Seam Tracker in the Cross Slides Column and Boom:

During the entire welding process, it tracks position of welding torch, and manipulates the position to optimum condition. This is for the target of delivering best welding quality from the Precise Automatic Welding Manipulator;

2)      Origin of Seam Tracker in the Automatic Column and Boom:

Seam tracker is outsourced component in Welding Equipment, purchased from first class professional supplier in the industry;

3)      Constitutes of Seam Tracker in the Precise Automatic Welding Column and Boom:

This welding seam tracker consists of sensor, control box and actuator (motorized slider), etc.

4)      Working Principle of Seam Tracker in the Welding Equipment:

a)       Data on welding face variation is collected by sensor which touches workpiece during welding, and calculated by control system;

b)      Distance between welding torch and workpiece would be adjusted accordingly when it is necessary by actuator, assuring welding quality of the Welding Manipulator;

5)      Structure and Components of Seam Tracker in the Welding Column and Boom:  (Fig.2)

a)       This sensor adopts imported components and advanced assembly technology from the Ministry of Aviation and Aerospace, with high quality, long service life;

b)The two dimensional probe sensor: This probe sensor is applicable to overlap welding/ Fillet welding/ Butt welding adopted in Welding Equipment. Different probes, like mushroom type, Y type and roller type etc., are available for different workpieces of Welding Column and Boom;

6)      Controller of Seam Tracker Applied in Welding Manipulator:  (Fig.3)

a)       Using the latest CPU as its core part and assembled with anti-jamming control procedure, this controller is highly efficient and reliable. It has user friendly interface, light touching keys with 100k time’s life circle and graphics LCD, all of which make it much easier to operate, set procedure and control, during running of the Welding Manipulator;

b)      When equipped in the LHZ series Cross Slides Column and Boom, the controller is installed at of the front end of horizontal boom:  (Fig.4)

7)      Actuator of Seam Tracker in the Cross Slides Column and Boom:  (Fig.5)

a)       This actuator is motorized high precision sliders, with once through shape aluminum cover and reasonable compact structure;

b)      Inside, it uses straight line rail which runs fast and easily. It uses DC low voltage (DC 24V) motor as its drive element, which conforms to European, American and many other countries safety standards;

c)       In the process of Welding Column and Boom operation, this actuator serves as executing unit, for adjusting welding torch position of the LHZ Welding Manipulator;

8)      Model Selection of Seam Tracker in the Welding Manipulator:

There are 3 standard models of the seam tracing unit to choose from when applied in various kinds of Welding Equipment:

a)       ED-ST05 is for MIG/ TIG/ CO₂ welding;

b)      ED-ST10 is for SAW;

c)       ED-ST20 is for Tandem SAW;

For detailed parameters of the seam tracker, we will provide its manual as part of the technical documents of the LHZ series Precise Automatic Welding Column and Boom.
