5) Applicable Process Technology: Besides welding, which is the foremost important application of this machine tool, these Welding Roller Frame can also be used on fulfilling other major steps in the process of production, including Assembly/ Testing / Painting, etc. When being used for these carrying out these functions, the Welding Rotator equipment need to have special capabilities, such as water proof, or abrasion proof;

2. Applied Industries: These Welding Roller Carrier has very extensive application in many industries, for example: Petrochemical/ Pressure Vessel/ Boiler/ Pharmaceutical/ Pipeline, etc. These industries are pillar in industrial countries;

3. Related Welding Equipment with Welding Turning Rolls:

1) Application Form: These Welding Roller Frame machine tool is one of the three most widely applied conventional welding equipment. Usually it is not put into use separately (As individual equipment), but instead, working with the other two types of universal welding equipment: Welding Positioner, and Welding Manipulator (Manipulator Welding Machine);

2) Welding Center: Working together with robots and welding manipulator, Welding Turning Rolls can be composed into Welding Center of various tailor made technical specifications, to meet on personalized demand from customer:

3) Wuxi JACK exported to East Europe large Welding Center, composed of 1 set of LHZ5050 Manipulator Welding Machine, and 4 groups of HLK80 model Bolt Adjusting Welding Rotator: (Fig.2)

B. Major Classification on Wuxi JACK Welding Roller Bed:

1) Technical Characteristic: At first glance, these Welding Roller Carrier is a kind of “simple” and regular equipment, in terms of appearance and structure. On the other hand, based on specific customer demand and practical application, there are many variations with this welding equipment, with series of technical knowhow involved;

2) Way of Classification: The most popular and widely accepted way of classification on the Welding Roller Frame is based on: Adjustment way on the center distance of each group of the Welding Turning Rolls:

1. HGZ Series Self Adjusting Welding Rotator:

Wuxi JACK HGZ80 model self adjusting type of 80 ton loading capacity: (Fig.3)

1) The most salient feature with this branch of Welding Roller Bed in terms of structure, is the surrounding angle of the two groups of Welding Turning Rolls is adjusted automatically, based on diameter and weight of workpiece cylindrical parts put onto it. Which means, after loading workpiece onto the equipment, the swing angle will be adjusted and acquired automatically in the equipment;

2) The most obvious characteristic with Self Adjusting Welding Roller Frame in terms of appearance, is it has four pieces of Welding Turning Rolls in one set of Welding Roller Bed:

3) There are 4 pieces of symmetrically installed Welding Turning Rolls, in every set of Self Adjusting Welding Rotator: (Fig.4)

2. HGK Series Leadscrew Adjusting Welding Rotator:

Wuxi JACK HGK10 model leadscrew adjusting type, of 10ton loading capability: (Fig.5)

1) Way of Adjusting on Center Span of Welding Turning Rolls: This is by means of turning leadscrew, either with manual, or motor drive, in stepless way;

2) Loading Capacity Scope: HGK series Leadscrew Adjusting Welding Roller Bed belongs to relative light duty equipment, compared with the other two types of: HGZ series Self Adjusting, and HLK series Bolt Adjusting types. The largest loading tonnage with HGK series leadscrew adjusting in standard model is 60~ 100 Ton;

3) Advantage of High Precision Positioning: On the other hand, HGK series Leadscrew Adjusting Welding Turning Rolls also has the highest precision to fit on various diameters of workpieces pipes, compared with HGZ self adjusting type and HLK bolt adjusting type;

3. HLK Series Bolt Adjusting Welding Rotator:

Wuxi JACK HLK100 model Bolt Adjusting type, of 100ton loading tonnage: (Fig.6)

1) Way of Adjusting on Center Span of Welding Turning Rolls: This is by means of fitting the installation bolts into different grades of mounting holes:

Row of holes and fitting bolts in Wuxi JACK HLK100 model bolt adjusting Welding Roller Bed: (Fig.7)

2) Loading Capacity Range: Compared with the other 2 types of: HGZ series self adjusting and HGK series leadscrew adjusting type, here HLK series Bolt Adjusting Welding Rotator belongs to scope of heavy duty Welding Roller Carrier. For Wuxi JACK products, the largest loading tonnage in standard model is HLK1000 (1000 Ton loading capacity), and HLK2000 (1000 Ton loading capacity) in Special Made Welding Rotator;

4. Classification Based on Loading Capacity: In terms of loading capacity to accommodate on workpieces weight, Wuxi JACK Welding Rotator also have 3 branches of: Light duty, Medium duty and Heavy duty models within each group of equipment (HGZ, HGK, HLK series) to distinguish.

C. Classification on Wuxi JACK Welding Turning Rolls Based on Structure and Design:

On the basis of the above-mentioned differentiation on HGZ/ HGK/ HLK series Welding Roller Bed, there are also some sub categories with each series of the welding machine tool:

1. Stationary Welding Roller Carrier:

1) Wuxi JACK HGZ20 model stationary structure, of 20ton loading tonnage: (Fig.8)

2) This account for majority of the Welding Rotator use, which takes up around 60% in practical use;

2. Motor drive Moving type Welding Rotator:

1) Wuxi JACK HGZ20 model motorized moving type, of 20ton loading capacity: (Fig.9)

2) Usage: To cater for varied length workpiece, or length of the to be finished joint pipes, or to be easy for transporting or relocating the welding equipment, some of the Welding Roller Bed have motor reducer and wheels installed at its beneath, so as to acquire moving function;

3) Applicable For: Moving type Welding Turning Rolls is especially useful when working with Welding Manipulator, to work on fabricating long length finished joint pipes/ tanks;

3. Anti-Drifting Welding Rotator:

Wuxi JACK anti-drifting type, of HLK600 model (With 600ton loading capacity): (Fig.10)

1) Technical Features: This is a “High end” and complicated line of Welding Roller Frame, for preventing the workpiece from axial drifting, during its revolve and being welded, so as to acquire the best degree of precise positioning, and the optimum welding processing performance;

2) Loading Capacity Scope: Anti-Drifting Welding Rotator basically is to be seen at heavy duty bolt adjusting Welding Roller Bed, to be specifically, HLK500 model and above. This is because that, axial drifting phenomenon is usually happened in large and heavy tanks fabrication process;

4. Conventional versus Downward Press type Welding Turning Rolls:

1) Wuxi JACK HGK5 model downward press type: (Fig.11)

2) This is a kind of special design and made welding machine tool, specifically developed for clamping on and fabricating on small diameter and light tubes;

5. Other types of special made Welding Rotator, such as below set, HGK2 model with moving wheels/ rails, and fixture: (Fig.12)

D. Summary Wuxi JACK Welding Roller Carrier Product Family:

1. In this product family of Welding Rotator, we will make introduction in the principal sequence of:

1) HGZ series Self Adjusting type (Automatic) light to medium duty;

2) HGK series Leadscrew Adjusting type (Manual) light to light medium duty;

3) HLK series Bolt Adjusting type (Manual) light to medium to heavy duty;

2. And enrich each sub category of the Welding Roller Bed, with several conventional types and special design;
