A. Business Application of Cross Slides Welding Column and Boom:
1. When do Customers Consider on Purchasing Welding Manipulator?
1) Nomination: Welding Manipulator, the other name is Welding Column and Boom, is for fulfilling pipe fabrication of various diameters, wall thickness, length;
2) Support on Process Steps of: Internal and external welding, painting, assembling, testing, etc.;
3) The Type of finished Welding Seam: When applied as welding on pipes, which account for majority use of the Column and Boom Welding Equipment, both the longitudinal and circumferential welding, on external or internal of workpieces can be attained;
4) Wuxi JACK LHZ3030 model Automatic Column and Boom Welding Equipment, fabricating on pipes laid on HGZ Welding Rotator: (Fig.1)
2. Main Functions of Automatic Column and Boom Welding Equipment:
One set of LHZ series Welding Column and Boom can fulfils the tasks of:
1) Height direction Y axis position change: Welding torch moves up and down along vertical direction, to accommodate on different diameters of working parts pipe;
2) Horizontal direction X Axis welding operation: Welding torch moves forward and backward along length direction of workpiece pipe, to finish welding and or other operation along longitudinal seam;
3) A Axis Rotation: This is completed with the support from Welding Roller Bed: By means of revolve of the workpiece pipe, the circumferential welding can be implemented, either external or internal welding;
4) A set of Wuxi JACK LHZ6050 model large Cross Slides Welding Manipulator works on 3,000mm diameter large tanks: (Fig.2)
3. Application Style of Cross Slides Automatic Pipe Welding Equipment:
1) Applicable Workpieces: The is welding equipment is mainly used on cylindrical working parts production;
2) Application Form: In practical using field, Welding Column and Boom is seldomly applied solitarily. Instead, it is usually cooperated with Welding Turning Roll, to be composed into a Welding Center;
3) Applied Industries: Automatic Pipe Welding Equipment has the largest and extensive application in Petro-Chemical/ Oil and Gas/ Pharmaceutical / Pressure Vessel, etc.
B. Technical Issues from Perspective of Designing on Cross Slides Welding Manipulator:
1. Structure Appearance and Main Units of Cross Slides Welding Column and Boom:
At first glance, any set of this equipment is like a piece of erected cross, which is composed of:
1) One piece of solid and strong upright column;
2) One piece of high intensity horizontal boom;
3) Both are installed and secured onto an either stationary base or moving trolley;
A set of Wuxi JACK LHZ3030 model Cross Slides Welding Manipulator: (Fig.3)
2. Pivot in Skeleton of Cross Slides Welding Column and Boom:
1) Cross Slides Role in Welding Manipulator:
a) During running period, the connection and engaging between upright column and horizontal boom is by means of cross slides, which is the crucial part in any set of the Automatic Pipe Welding Equipment;
b) In Wuxi JACK delivered LHZ series Cross Slides Welding Manipulator, the cross slides applied in light duty and medium to heavy duty Pipe Welding Equipment are different, considering loading capacity difference:
c) Cross slides in Wuxi JACK light duty models: (Fig.4)
d) Cross slides in Wuxi JACK medium to heavy duty models: (Fig.5)
2) Cross Roll Bearing in Automatic Column and Boom Welding Equipment:
a) Another important unit during running period is cross roll bearing, which is mounting connection between upright column and fixed base bed or travelable trolley:
b) The high precision cross roll bearing in Wuxi JACK Automatic Column and Boom Welding Equipment: (Fig.6)
3. Main Specifications of Automatic Pipe Welding Equipment:
When customers select a set of Welding Column and Boom, below are critical factors for consideration:
1) The max. extending stroke of horizontal boom, this is determined on the basis of the longest length of working parts pipes;
2) The max. elevating stroke of horizontal boom, this is determined according to the largest diameter of workpiece parts;
3) For example: LHZ3x4 model refers to the Cross Slides Welding Manipulator, with max. 3000mm elevating stroke, and 4000mm extending stroke;
4) Whether the upright column is necessary to revolve or not in the Welding Manipulator?
a) Majority conditions, the answer is yes. Because this can multiply working scope of the Automatic Pipe Welding Equipment;
b) If yes, whether the revolve is manual or motor drive? The selection from customers is usually half and half;
5) Whether the entire set of Welding Column and Boom capable of moving or not?
a) Customers who choose on moving style is more than choosing on fixed style equipment;
b) When the equipment is movable, its movement is driven with A.C. motor, and on a parallel rails;
4. Outsourcing Function Units for Automatic Column and Boom Welding Equipment:
Basically, a set of Welding Column and Boom is a mechanical trunk, with its functions realized by means of function units installed on the front end of its boom. The common seen equipped elements can be listed as:
1) Welding torch, including SAW (Submerged arc welding)/ TIG/ MIG/ CO2/ GMAW...;
2) Welding wire feeding reel and tubes;
3) SAW Welding flux conveying and recovery system, when the welding equipment is adopted with SAW mode;
4) Welding control consoles, for managing welding operation;
5) Typical function units installed onto Wuxi JACK Cross Slides Welding Column and Boom exported to Indonesia: (Fig.7)
C. Safety Issues when Putting into Use of Cross Slides Automatic Pipe Welding Equipment:
1. Importance of Safety during Running of Welding Manipulator:
1) Foremost Consideration: Of all the common seen Welding Equipment in the industries: Welding Manipulator, Welding Positioner, Welding Roller Bed, the Welding Manipulator should be paid primary attention on its security, which is because of its structure and working features:
2) Hidden Trouble One: Because the entire set of the column and boom welding equipment is a piece of erected cross slides, its stability should be guaranteed first, to avoid the serious phenomenon of tumbling down;
3) Hidden Trouble Two: Besides, when the horizontal boom is raised to its higher level when the equipment is working on a piece of large diameter pipe, the sudden falling of the horizontal boom may cause serious outcome;
2. Stability of Welding Column and Boom Erection:
So, how to prevent the above mentioned hidden trouble from happening?
1) The gravity center of the entire set of Welding Manipulator base, its main body is solid and firm, to stabilize the equipment operation;
2) So, the base needs a counter weight to avoid accidental overturning of the welding equipment;
3. Prevent Horizontal Boom from Falling Down in Automatic Column and Boom Welding Equipment:
This is realized by means of safe holes, cut into the upright column: (Fig.8)
D. Summary on Wuxi JACK Cross Slides Welding Column and Boom:
Summing up, as Chinese top grade professional supplier on all kinds of Welding Equipment with long term experience and outstanding technical capability, Wuxi JACK can deliver full line of LHZ series Cross Slides Welding Column and Boom, with the top grade quality, the most reasonable price, and the best service for customers.
