A. Function and Capability of Welding Column and Boom:

1. Working Principle: Welding Column and Boom gets its name from its overall appearance of this Welding Manipulator: A set of solid and flexible mechanical erecting cross, assembled from horizontal boom and upright column with a strong base, for performing longitudinal and horizontal welding operations on cylindrical working parts: Vessels/ tanks/ pipes...;

2. Working Manner of Welding Manipulator Tank Welding Equipment:

1) Structure Feature: This cross slides Tank Welding Equipment itself is a type of Welding Manipulator for managing on welding operation, without welding fixtures for carrying on workpieces;
2) Working Way: So, Welding Column and Boom usually works together with other common seen Welding Equipment: Welding Rotator and or Welding Positioner, composing into general purpose Welding Center:

4) Large Welding Center: Wuxi JACK LHZ6060 Welding Column and Boom implements on external longitudinal welding on oil pipelines at customer site, working with groups of hydraulic drive Welding Roller Bed: (Fig.2)

3. Wide Application: In manufacturing industries, Welding Column and Boom is the most efficient Tank Welding Equipment, for completing on common welding operations on various materials/ dimensions/ structures of workpieces. So, this LHZ series cross slides Welding Manipulator has gained very extensive applications worldwide;

4. Major Welding Operations to be Carried Out in Welding Column and Boom:

1) Longitudinal Welding: By means of horizontal movement of boom, Welding Column and Boom carries out longitudinal welding on external and or internal wall of workpieces;
2) Circumferential Welding: When horizontal boom of Welding Manipulator keeps motionless status in stationary, and hence is its welding torch, with revolve of workpiece on Welding Turning Roll, circumferential welding can be fulfilled on both internal and or external wall of workpieces;
3) Internal or External Welding: Working head (Horizontal boom) of Welding Column and Boom can either “crawl on” external wall of tanks, or extends into internal wall of tanks, acquiring on both positions of welding on workpieces;
4) Flexible Welding Mode: Nearly all the common adopted welding units in Tank Welding Equipment: SAW/ GMAW/ Strip Cladding/ TIG... can be equipped to Welding Column and Boom.

 

B. Put into Use on Welding Column and Boom:

1. Working Hand: The horizontal boom acts as operating hand, or manipulator of the Tank Welding Equipment. Correspondingly, welding units of Welding Manipulator: Welding torch/ Welding wire feeder/ Welding control console... are installed at front end of the horizontal boom. For this reason, LHZ series Welding Column and Boom is also named as “Cross Slides Welding Manipulator”:

Welding function system being installed at front end of horizontal boom of Welding Manipulator Tank Welding Equipment: (Fig.3)

2. Cross Slides Role in Operation of Welding Column and Boom:

The movement of horizontal boom:
1) In X axis along horizontal direction --- This corresponds with adjustable welding velocity of the Welding Column and Boom;
2) In Y axis along vertical direction --- This corresponds with varying diameters of tanks in Welding Manipulator Tank Welding Equipment;
a) Comes into being the central working movement of Welding Column and Boom, which is managed with the delicate design sophisticated cross slides:

c) Cross slides being assembled into erected Wuxi JACK Welding Column and Boom: (Fig.5)

C. Select Proper Model of Cross Slides Welding Column and Boom:

1. Taking LHZ5060 Model Welding Column and Boom as Example:

1) “50”— The max. vertical up and down stroke of horizontal boom, which equals to the max. diameter of pipes/ tanks being welded in Welding Column and Boom;
2) “60” – The max. horizontal stroke of horizontal boom, which equals to the max. length of pipes/ tanks being welded in the Welding Manipulator Tank Welding Equipment;
3) In summary, the largest working parts to be welded in this LHZ5060 Cross Slides Welding Column and Boom: Pipe/ tank diameter is Φ5000 mm, and pipe/ tank length is 6000 mm;

2. Main Optional Configurations of Welding Manipulator Tank Welding Equipment:

Besides, according to on site process technology design and requirement of customer facility, Welding Column and Boom can be in the form of:
1) Moving or Not: On stationary fixed mechanical base, or with motorized moving trolley. If with moving function, the moving distance of the Tank Welding Equipment Welding Manipulator is usually designated by customers:

Moving versus stationary Welding Column and Boom: (Fig.6)

2) Column Revolve or Not: The upright column can be non-revolving, or with manual / motor drive revolving function;
3) These optional configurations extends working capability of Welding Column and Boom;
3. Summary on strong points and technical specialties of our Welding Manipulator Tank Welding Equipment is illustrated in product page of “Introduction on Wuxi JACK Welding Column and Boom”.

2) Applicable Sites: GMAW welding has high impact value (IK), which is often applied in Pharmaceutical, or Vehicle industries;

3. Strip Cladding in Cross Slides Welding Column and Boom:

1) Technical Features: This is for building up a layer of anti-corrosion on surface of workpieces. So, strip cladding is also named as built up welding;
2) Welding Modes: In Welding Column and Boom, it can be SAW or ESW (Electroslag) welding;
