Multi-Scenario Dual-Robot Aluminum Alloy Laser Tracking Welding Workstation

Multi-Scenario Dual-Robot Aluminum Alloy Laser Tracking Welding Workstation

Overview

This multi-scenario dual-robot aluminum alloy laser tracking welding workstation runs two synchronized 6-axis manipulators from one controller: the lead arm fixtures and rotates the aluminum workpiece while the follower arm carries the welding torch along the joint. Because both arms share the same motion clock, the weld pool stays in position even while the part is repositioned, which removes the re-clamping steps that normally break an aluminum seam into short segments.

Laser tracking is the second half of the concept. A laser seam tracking sensor mounted ahead of the torch scans the joint, measures gap, mismatch and bead position, and feeds correction data to both arms in real time. On aluminum that closed loop is decisive: the alloy conducts heat away quickly, the process window is narrow, and any drift in torch-to-joint distance appears immediately as porosity or lack of fusion. With laser tracking welding running continuously, the workstation holds the arc in the joint even when pressed or extruded profiles vary from batch to batch.

The motion platform follows the M-10iD/12 specification of 12 kg wrist payload, 1441 mm maximum reach, 6 controlled axes and 0.02 mm repeatability, so torches, wire feeders, push-pull guns and tooling already engineered for that class of arm can be reused without redesign. One operator can supervise several of these workstations, and the same program set can be re-deployed from a floor-mounted station to an inverted gantry or an angled fixture, which is what makes the cell genuinely multi-scenario rather than single-line equipment.

Key Specifications

Advantages

• Synchronized dual-robot motion. Both arms interpolate on one timeline, so the torch follows the part instead of the part chasing the torch, cutting clamp-and-release steps from every aluminum seam.
• Laser tracking instead of teach-and-pray. The sensor corrects gap and mismatch continuously, keeping laser tracking welding stable across pressed, extruded and cast aluminum profiles.
• Multi-scenario mounting. Floor, inverted and angled installation is supported from the same arm and program set, so the workstation can be re-tasked when product mix changes.
• Payload headroom for real tooling. 12 kg at the wrist carries a water-cooled torch, push-pull feeder, laser sensor and camera without derating the motion envelope.
• 0.02 mm repeatability. Positional consistency that protects thin aluminum sections from burn-through and distortion over long production runs.
• Service-friendly architecture. Hollow wrist cable routing, integrated air and 8/8 signals on the upper arm reduce cable wear, the most common cause of welding cell downtime.
• Fast changeover. Programs, tool frames and tracking recipes are stored per part, so switching from a battery tray to a rail beam is a recipe call, not a re-teach.
• Compact footprint. A 340 x 340 mm base and 145 kg arm weight allow dense two-arm layouts without special foundations.

Applications

• Automotive aluminum sub-assemblies: battery trays, door frames, cross members
• Rail and metro aluminum profiles and side-wall panels
• Architectural aluminum facades, curtain wall mullions and handrails
• New energy housings, busbar frames and thermal management parts
• Appliance and HVAC aluminum cabinets and heat exchanger shells
• General job-shop MIG and TIG welding of medium aluminum batches

FAQ

Q: What makes this a multi-scenario dual-robot welding workstation?
A: Two synchronized arms share one controller, and the platform can be mounted on the floor, upside down or at an angle. The same multi-scenario workstation can therefore serve a fixed station, a gantry line or a rotary table without changing the arm or the program structure.

Q: How does laser tracking welding improve aluminum seams?
A: Aluminum conducts heat away fast and has a narrow process window. The laser sensor scans the joint ahead of the arc and corrects both arms in real time, so the workstation keeps the torch centred when profile tolerances vary between batches.

Q: How do the 12 kg payload and 1441 mm reach translate into practice?
A: The 12 kg wrist payload covers a water-cooled torch, push-pull wire feeder, laser sensor and camera, while the 1441 mm reach handles parts up to roughly 2.8 m across when two arms work from opposite sides.

Q: Is the workstation safe for operators working alongside it?
A: The platform supports force-limited and speed-and-separation monitored operation with the appropriate safety options. We confirm the safety configuration, risk assessment documents and guarding concept against your local requirements before shipment.

Q: Which welding processes are supported?
A: MIG, pulsed MIG, TIG and laser-hybrid torches can be integrated. Torch, feeder, laser sensor and gas control are selected for the alloy, thickness and bead profile you specify.

Q: How long does commissioning take?
A: A standard two-arm workstation is typically installed and welding production samples within 5 to 10 working days on site, including laser tracking calibration and operator training.

Q: Can you supply the fixture, positioner and safety package as well?
A: Yes. We quote the arms, controller, laser tracking system, positioner, fixture and guarding as one deliverable so the interfaces are our responsibility, not yours.
