High Precision Welding Manipulator for Pressure Vessel Production Line

Product Description

Product Overview

Pressure Vessel Welding Manipulator, also known as a welding column and boom, is a high-automated auxiliary equipment essential for the welding industry. By utilizing column rotation and boom retraction/lifting, it precisely meets the welding requirements of cylinders across various sizes.

The welding head is securely fixed at one end of the boom to facilitate automatic welding. This versatile system can be integrated with welding rotators or tank turning rollers to perform high-quality internal and external longitudinal and circumferential seam welding. It is extensively applied in Boiler, Petrochemical, Shipbuilding, and Steel Structure industries.

Key Features
Flexible Structures: Available in fixed type, fixed with rotation, and movable models to suit different workshop layouts.
High Durability: Both column and boom are cold-blended and undergo annealing treatment for stress relief and long-term stability.
Safety First: Equipped with an anti-falling device to ensure maximum safety during boom lifting operations.
Smooth Operation: Boom retracting adopts VFD (Variable Frequency Drive) for stable and reliable movement.
Precision Control: X-Y slide is fixed on the boom end, easily managed via a hand-held control panel.
Minimal Clearance: Control rollers utilize eccentric shafts to decrease the clearance between the roller and the rail.
Versatile Rotation: Column revolution can be achieved through either manual operation or electric drive.
Integrated Interface: Control unit includes an electric board and hand panel, with interfaces for positioners and rotators.
Advanced Options: Supports trolley integration, director chairs, drag chains, seam tracking, and flux recovery systems.

Frequently Asked Questions (FAQ)
What is the primary function of a welding manipulator?
It is used to hold and move a welding head over a workpiece to perform automated welding on cylinders, pressure vessels, and large steel structures.
Can this equipment handle different sizes of pressure vessels?
Yes, the boom lifting and retraction strokes are adjustable, allowing it to accommodate cylinders of various diameters and lengths.
What safety mechanisms are included in the boom system?
Every unit is equipped with an anti-falling safety device to prevent accidental drops during boom lifting operations.
Is the equipment compatible with other welding auxiliaries?
Absolutely. It is designed with interfaces to work seamlessly with welding rotators, positioners, and tank turning rollers.
What control options are available for the operator?
Operators can use both a main electric control board and a convenient hand-held control panel for precise adjustments during the welding process.
How is the boom speed regulated?
The boom retracting speed is controlled via a Variable Frequency Drive (VFD), providing a stable range from 120 to 1200 mm/min.
