1. What is Special Welding Rotator?

1) The Definition on Standard Welding Pipe Rotator

In the product pages of “Welding Pipe Rotator”, “Welding Pipe Rotator in Use” and “Conventional Standard Welding Pipe Rotator”, we discuss the general classification on Welding Pipe Rotator, and 3 types of standard welding roller bed and welding turning roll:
a) HGZ Self Adjustable Welding Pipe Rotator;
b) HGK Leadscrew Adjustable Welding Pipe Rotator;
c) HLK Bolt Adjustable Welding Pipe Rotator;
Which account for over 50% application cases in industry;

2) When and Why do You need Special Welding Rotator?

a) Meanwhile, in practical use, there exist fairly amounts of conditions, that standard types of Welding Pipe Rotator can not meet customer demand under specific scenarios. This is often originated from special and complicated working parts;
b) Correspondingly, series of upgrade and retrofitting on design of welding roller bed and welding turning roll are necessary;

3) These Retrofitting Measures on Development of Special Welding Rotator include but not Limited to:

a) Anti Drift Welding Rotator;
b) Traveling type welding roller bed;
c) Fixture type Welding Pipe Rotator;
d) Integrated structure and function of HGZ Self Adjusting with HLK Bolt Adjusting Welding Pipe Rotator;
e) More degree of freedom in welding turning roll than conventional Welding Pipe Rotator…

2. Below is a Glimpse on Assembly of Special Welding Pipe Rotator (Anti Drift Welding Rotator) at Wuxi JACK facility: (Fig.1)

1. Position and Scope of Anti Drift Welding Rotator:

1) Anti Drift Welding Rotator belongs to a branch of HLK series bolt adjustable Welding Pipe Rotator. Due to its important position and people’s special attention on such kind of Anti Drift Welding Rotator, we take Anti Drift Welding Rotator as an independent product group of Welding Pipe Rotator;
2) Anti Drift Welding Rotator is applied in the range of HLK series heavy duty bolt adjusting Welding Pipe Rotator, usually from loading capacity of 80Ton (HLK80) to 500Ton (HLK500) welding roller bed;

2. Why is it so Important of Anti Drift Welding Rotator?

1) In the application of Welding Pipe Rotator, there is a kind of frequently happened issues in circumferential welding of large size and heavy duty working parts, which have wide applications in industries of Oil Field, Petrochemical, Marine Engineering… That such kind of workpieces usually need several rounds of welding seam for its fabrication with Welding Pipe Rotator;
2) Suppose carry out circumferential welding on these large heavy working parts with ordinary Welding Pipe Rotator, the working parts are prone to skid a little bit, which makes deviation of finished welding seam. This leads to inferior welding quality. Under these conditions, you may need select Anti Drift Welding Rotator.

3. The Control Theory of Anti Drift Welding Rotator:

1) The anti drifting function is realized with idler section welding roller bed of the Welding Pipe Rotator, which makes adjustment on position of workpiece by means of uplifting a certain stroke, after getting the command from control system of Anti Drift Welding Rotator;
2) The modulating movement of idler welding roller bed is implemented in two ways: Either manual control, or automatic control of Welding Pipe Rotator;
3) In the product section of HLK Hydraulic Jack Up Bolt Adjustable Anti Drift Welding Rotator and HLK Traveling Bolt Adjustable Anti Drift Welding Rotator, we introduce in detail the mechanical arrangement, especially idler welding roller bed, control system and special point of Anti Drift Welding Rotator. If you are interested, please check.

1. Purpose of HGK Down Pressure type Leadscrew adjustable Welding Pipe Rotator:

1) Many of special Welding Rotator is made on the basis of HGK Leadscrew adjustable welding roller bed. This is because that, leadscrew adjusting Welding Roller Bed is the type of Welding Pipe Rotator with availability on precisely and continuously managing workpiece diameter;

2) Besides, HGK Leadscrew adjustable Welding Pipe Rotator is for processing light duty working parts, which is prone to skidding during rotating circumferential welding process, especially those with lightweight working parts;

3) This down pressure type special made Welding Pipe Rotator is developed for such kind of application scenario. By means of its downward stroke welding turning roll, the small and light workpieces can be held firmly and reliably with three points acting.

2. Structure and Working Principle of Down Pressure type Leadscrew adjustable Welding Pipe Rotator:

In the product HGK Down Pressure type Leadscrew Adjustable Welding Pipe Rotator, we give detailed introduction it.

3. Technical Parameters of Down Pressure type Leadscrew adjustable Welding Pipe Rotator:

As mentioned earlier, such kind of down pressure type special Welding Rotator is applied to light duty loading capacity of 2Ton welding roller bed:

1. What is Integrated Function Welding Pipe Rotator?

1) Integrated function Special Welding Rotator is combination of two types of welding roller bed;

2) For example, the stock of Welding Pipe Rotator in the first photo at left hand:

a) At first glance you may judge these are self adjustable welding roller bed, judging from its way of arrangement on welding turning roll: There are 4 pieces of welding turning roll in one set of welding roller bed;
b) On the other hand, checking the structure of its welding roller bed, this is also a bolt adjustable Welding Pipe Rotator. So, it is a set of HGZ and HLK integrated Welding Pipe Rotator;

2. The Benefit of Integrated Function Special Welding Rotator:

1) With such combination of HGZ self adjusting and HLK bolt adjusting welding roller bed, this integrated function Welding Pipe Rotator can get wider range of applicable working parts, in terms of both diameter range and thickness;
2) We know each kind of standard Welding Pipe Rotator has its unique advantages and application focus. With such combination of welding roller bed and welding turning roll, this kind of integrated function Welding Pipe Rotator plays the double function and merit of both self adjusting and bolt adjusting welding roller bed.

2. Technical Parameters of Integrated function Special Made Welding Pipe Rotator:

Technical parameters of such integrated function special Welding Rotator depends on specific design. The welding roller bed in the left hand photos has 80ton loading capacity.
