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...;
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:
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;
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.
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”:
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:
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;
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:
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;

1) Function: The movement of welding torch in operation of Welding Column and Boom is realized by means of its horizontal boom movement with respect to upright column, in the direction of horizontal X axis and vertical Y axis. Such both direction position management is guided and transmitted by way of cross slides, which is assembled at intersection point of boom and column in the Welding Manipulator:
2) Up and Down: With elevation of horizontal boom, the welding torch height level of Welding Column and Boom can be managed, based on size and diameter of workpiece tank in the Tank Welding Equipment;
3) Leftward and Rightward: By means of horizontal extending and retreating of boom, the operating reach of welding torch in the Welding Column and Boom can be controlled;
4) Welding Speed: When performing on longitudinal welding at Welding Manipulator, horizontal movement of boom equals to movement of welding torch. For this reason, in operation of the cross slides Welding Column and Boom, boom horizontal speed is working welding speed of Welding Column and Boom, which is controlled with A.C. inverter, and displayed in digital manner in real time.
1) High Power A.C. Motor: as shown in the above 1st photo, for driving the horizontal boom up and down movement in Welding Column and Boom. This driving motor is installed at top of the upright column;
2) For Large Welding Column and Boom: Sometimes, to reduce total height of Welding Manipulator, especially large models, this drive motor is installed at bottom of the upright column, inside its mechanical base bed. This also helps lowering down gravity center of the Tank Welding Equipment;
3) Precise Worm Gear and Motor Reducer of Welding Manipulator, as shown in the above 2nd photo, for driving and transmitting horizontal boom movement in the Tank Welding Equipment, along X and Y axis;
a) The biggest safety hidden risk during operation of Welding Column and Boom is sudden falling down of horizontal boom from high level position;
b) To avoid this from happening, there is a row of rectangular holes cut in the upright column of the Welding Column and Boom. During work, if ever chains break off and lead to sudden falling of the horizontal boom, the rachet safety pins will be ejected out immediately, firmly locking the horizontal boom into that position. This is marked in yellow frame in the above 1st photo;
c) The climbing ladder alongside the upright column in Welding Manipulator is surrounded with protection rails, as shown in orange frame in the above 1st photo;
2) Brake Motor: The driving motor for horizontal boom elevation in Welding Column and Boom is braking type. This gives double assurance on protecting the horizontal boom from unexpected falling down;
3) More information on safety measures taken in Wuxi JACK LHZ series Welding Manipulator is introduced in product section of “Industrial Use Welding Column and Boom”.
1) Operating Point Welding Heads of different configurations in LHZ Integral Control Welding Manipulator: The above 2nd and 3rd photos show welding heads of this Tank Welding Equipment;
2) Welding Modes: It can be any common seen welding modes in available in Welding Manipulator. The control console of welding power supply/ Welding seam tracker/ Welding wire feeder are all installed on front end of the horizontal boom, for acquiring on easy management and monitor on high standard running of the Welding Column and Boom by operators;
3) Hand held Remote Operating Pendant of the Welding Manipulator: As shown in the above 4th photo. This operating pendant helps operator managing on operation of the Welding Column and Boom in further distance, so as to have flexible working positions according to practical working conditions.
1. Working Manner: Welding Manipulator works with other Welding Equipment to deliver various welding jobs: Welding Rotator (Welding Turning Roll, Welding Roller Bed) for circumferential welding, and or Welding Fixture for longitudinal welding, and or Welding Positioner for structure welding, to be formed into wide variety of Welding Center;
2. Similar function of Welding Equipment with respect to Welding Column and Boom includes various types of Pipe Welding Machine, which is more flexible in structure/ configuration and functions; Longitudinal and circumferential Welding Equipment, which can also implements on both types of welding seam, but with much smaller size;
3. Applicable Workpieces: Besides cylindrical working parts such as pipes/ tanks, as shown in the above photo, Welding Column and Boom can also be used for fabricating on structure members: H Beam/ BOX Beam when working on longitudinal seam welding. This fulfils similar tasks as 3 in 1 H Beam Welding Machine.
