4) Wuxi JACK LHZ4040 Column and Boom Welding Manipulator produces on large pipes, running with 2 sets of HGZ10 self-adjusting welding roller support: (Fig.2)

2. Task of Manipulator Column and Boom Welding Machine:

This welding machinery produces two types of welding seam on workpieces, under different welding modes:

1) Longitudinal Seam Welding: On internal and external surfaces of workpieces, so as to finished close on each segment of pipe/ tank for its production;

2) Circumferential Seam Welding: On internal and external surfaces of workpieces, so as to complete butt joint on 2 segments of pipes, to get a longer integral piece of pipe:

3) At Customer Site: Wuxi JACK exported to Russia LHZ5050 Column and Boom Manipulator Welding Machine, produces large tanks in batch in Petrochemical plant: (Fig.3)

B. Structure and Working Principle of Column and Boom Manipulator Welding Machine:

1. Constructure and Balance of Manipulator Welding Column and Boom:

1) General View: This welding machinery has regular and “simple” structure of horizontal boom and upright column being assembled into an assembly of cross slides, and mounted onto mechanical base;

2) Erected in Balance: Installed onto a fixed mechanical base or moving trolly, the balance of the entire machine is kept in the way of proper design, as well as precise assembly of horizontal boom with upright column. In this respect, safety assurance of Welding Manipulator is of vital importance during its daily operation, especially for those large models:

2. Loading Capacity of Horizontal Boom Front End of Column and Boom Welding Manipulator:

1) Where Referred to: Welding function mechanisms of this machine is installed at front end of its horizontal boom. Because of there are numerous pieces of working cells involved: Welding torch head and its positioning mechanism, cross slides with precise linear guiderail, welding wire reel and feeder, control console of welding power supply...

2) Summing up, the total weight of these function units amounts to several tens of kilograms to several hundreds of kilograms, which may lead to negative effect of horizontal boom drooping down, and in turn affect safety and performance of the Column and Boom Welding Manipulator itself;

3) For this reason, loading capacity of horizontal boom, which is determined from its mechanical strength and intensity, is one of the key technical performance indexes of the Column and Boom Manipulator Welding Machine:

4) SAW Welding function cells being installed at front end of horizontal Boom, in Wuxi JACK LHZ3030 model machine: (Fig.5)

3. Operation of Column and Boom Manipulator Welding Machine:

Welding operation of this Automatic Column and Boom Welding Equipment is by means of its horizontal Boom movement:

1) For Longitudinal Seam Welding: In the form of forward and backward movement along horizontal direction, X axis;

2) For Circumferential Seam Welding: Welding torch and its functional units keep still, and be positioned precisely right above the workpiece, while workpiece pipe revolves in linear speed of welding on welding roller bed;

3) When diameter of workpieces change, horizontal boom moves up or down accordingly, making sure height level of welding torch to be kept at welding point precisely;

4) Operator stays at certain distance away from the machine, operating and monitoring welding operation by means of hand held remote pendant:

5) Testing on operation of Wuxi JACK LHZ5050 Manipulator Column and Boom Welding Machine before delivery by operator: (Fig.7)

C. Application of LHZ Series Manipulator Welding Column and Boom:

1. Extensively Applied Industries:

This machine is widely applied in industries with finished products of various cylindrical parts: Pharmaceutical/ Pressure Vessel/ Petro-Chemical/ Oil Tank/ Offshore Wind Tower/ Boiler, etc. In these manufacture realms, this Welding Manipulator machinery is indispensable in daily operation;

2. Operating “Partner” of Automatic Column and Boom Welding Equipment:

1) Welding Center: In practical application, this machinery usually works together with other automatic welding equipment, thus composing into simple or complicated configuration of welding centers;

2) The Most Common Collaborated Welding Equipment include: Welding Rotator and or Welding Positioner, to have central integrated control of these machineries, composing tailor made Welding Center of different specifications, meeting personalized customer demand on work parts welding;

3. Welding Mode Adopted in Column and Boom Welding Manipulator:

1) All the mainstream and novel welding modes: SAW (Submerged arc welding), GMAW CO₂, Strip Cladding (Built up welding), narrow width welding... can all be equipped with this Manipulator Welding Machine;

2) Three major types of welding mode, and related heads and function system, installed at horizontal boom: (Fig.8)

4. Major Function Units Equipped in Manipulator Welding Column and Boom:

This Manipulator Welding Machine can be equipped with numerous optional function components:

1) Different models of welding power supply and its control console;

2) Lasor or pneumatic type welding seam tracing unit;

3) Welding wire feeding and straining unit;

4) Welding torch oscillator;

5) Graphic video monitor;
