Welding column and booms (also known as welding manipulators) are versatile pieces of equipment used to automate and improve the efficiency and quality of welding, especially for long, circumferential, or repetitive welds on large workpieces. They primarily differ based on their mobility, size/capacity, and sometimes the degree of articulation or control.
Welding Column Booms Types
Fixed Type (Stationary):
Description: The base of the column is bolted directly to the workshop floor or a heavy foundation.
Use Case: Ideal for dedicated welding stations where the workpiece is brought to the manipulator. Often used for repetitive tasks on similar-sized components.
Pros: Very stable, takes up a defined footprint.
Cons: Lacks mobility; workpiece positioning is critical.
Movable Type (Free-Standing / Portable):
Description: The column is mounted on a heavy base equipped with casters or wheels, allowing it to be moved around the workshop. It might be moved manually or have a simple motorized drive for positioning.
Use Case: Offers flexibility to move the manipulator to different workpieces or work areas within a bay.
Pros: More versatile than fixed types for varied job locations.
Cons: May require leveling or outriggers for stability during operation, especially for larger models.
Track/Rail Mounted Type (Travel Car Type):
Description: The column and boom assembly is mounted on a motorized carriage that runs on precisely laid rails or tracks on the floor.
Use Case: Essential for welding very long longitudinal seams on items like large pipes, tanks, beams, or ship hulls. The manipulator travels along the length of the workpiece.
Pros: Accurate linear movement over long distances, high productivity for long welds.
Cons: Requires dedicated track installation, less flexible for non-linear work.
Size/Capacity Based Classifications (often overlaps with the above):
Light-Duty:
Shorter boom reach (e.g., up to 2-3 meters).
Lower payload capacity (for lighter welding heads and accessories).
