MISA Manufacturing -- Wuxi, China
Column & Boom Welding Manipulators
MISA's column-and-boom welding manipulators deliver precise, automated torch positioning for large and complex workpieces -- eliminating the need to reposition heavy assemblies while consistently achieving high-quality welds across long seams, circumferential joints, and hard-to-reach zones.
- Multi-axis freedom -- vertical column and horizontal boom allow full torch travel without moving the workpiece.
- Broad application range -- pressure vessels, large-bore pipe, wind towers, structural steel, and shipbuilding components.
- Production gains -- reduced operator fatigue, shorter cycle times, and repeatable weld quality at every shift.
- Structure
- Heavy-Gauge Steel
- Control
- Wired & Wireless
- Voltage Range
- 110 - 600 V
- Integration
- Rotator / Positioner
Product Range
Four structural types for every payload and motion requirement.
From light workshop units to motorized heavy-duty gantries, MISA manufactures each manipulator class to match the duty cycle, reach envelope, and mobility demands of your fabrication environment.
Light Type
Compact column-and-boom units engineered for smaller workshops and moderate-size workpieces. Ideal for pipe spool and light structural fabrication where floor space is a premium.
- Lower column height range
- Reduced footprint design
- Fast repositioning speed
Heavy Duty Type
Robust heavy-gauge steel construction engineered for large pressure vessels, wind tower sections, and shipbuilding components. Built for sustained high-amperage, multi-shift duty.
- Extended vertical & horizontal stroke
- Anti-backlash precision gearing
- High-load boom capacity
Fixed Type
Permanently anchored to the shop floor for dedicated welding stations. Offers maximum structural rigidity and is the preferred solution for high-volume repetitive production lines.
- Anchored base for zero deflection
- Optimised for production-line cells
- Simplified civil foundation design
Motorized Moving Type
Rail- or track-mounted units with powered longitudinal travel. Enables the manipulator to track long weldments or move between multiple bays without manual intervention.
- Motorized rail travel drive
- Variable longitudinal travel speed
- Multi-bay flexibility

Advanced Accessories & Options
Tailor your manipulator with process-specific accessories that integrate directly into the column-and-boom assembly or control cabinet.
Camera Monitoring Systems
Dedicated camera rigs for SAW, MAG, and TIG arc monitoring -- allowing operators to observe the weld pool remotely and adjust parameters in real time.
Cross-Slide & Rotation Head
Cross-slide units provide fine torch tracking adjustment; rotation heads enable rapid switchover between longitudinal seam and circumferential seam welding orientations.
SAW Flux Recovery System
Integrated flux hopper, recovery vacuum, heating cabinet, and rotary sieve -- enabling continuous submerged arc welding without manual flux handling.
Twin-Wire & Narrow-Gap Heads
High-deposition twin-wire SAW heads and narrow-gap TIG/MIG torches for thick-section pressure vessel and nuclear component fabrication.
Why MISA
Solving the hard problems of heavy manual welding.
Large-structure hand welding introduces compounding risks -- inconsistent quality, operator fatigue, schedule overrun, and elevated safety exposure. MISA manipulators address each of these at the engineering level.
Inconsistent Weld Quality
Manual positioning introduces arc-length variation, travel speed drift, and torch angle error -- all leading to NDT failures, rework cost, and schedule delays.
MISA Solution
Motorized boom and column travel at programmable, constant speed -- maintaining exact torch-to-work distance and travel angle throughout the joint.
Operator Fatigue & Safety Risk
Welding at height or in confined positions on large structures increases musculoskeletal injury risk and sustained concentration demands that degrade quality over a shift.
MISA Solution
Wireless pendant control up to 90 m lets the operator stand at a safe, ergonomic distance. Camera monitoring eliminates the need for elevated observation.
Long Production Cycle Times
Repositioning heavy workpieces between weld passes consumes crane time, floor space, and skilled labor -- compounding into significant schedule and cost overrun.
MISA Solution
The torch travels to the joint -- not the other way around. Combined with rotator or positioner synchronization, full circumferential and longitudinal seam sequences run without a crane lift.
Harsh Environment Durability
Weld spatter, vibration, thermal cycling, and continuous-duty operation rapidly degrade lower-specification equipment -- causing downtime at the worst possible moments.
MISA Solution
Heavy-gauge welded steel frames, precision hardened-rail guidance, and anti-backlash gearing are specified for multi-shift industrial duty -- not occasional workshop use.
Seamless integration with your complete welding cell.
MISA column-and-boom manipulators are designed from the ground up to synchronize with MISA vessel rotators, pipe turning rolls, and hydraulic positioners -- creating a fully automated welding cell controlled from a single operator station. PLC integration and custom control architectures are available for turnkey production line projects.
- Vessel rotator sync
- Positioner coordinated motion
- PLC / HMI automation
