SA6-1440H 6kg Payload 1440mm Welding Robot Arm Multi Pass Arc Tracking Cell

Overview

• • The SA6-1440H 6kg Payload 1440mm Welding Robot Arm Multi Pass Arc Tracking Cell is configured for thicker sections that need several weld runs on the same joint.
• • A 1440mm reach covers a fixture table plus the weld zone, and the hollow wrist keeps the torch cable clear when the torch rotates for vertical and overhead passes.
• • The arc tracking function follows gap and mismatch variation along the joint, which matters when fit up quality changes between parts.
• • Repeatability of plus or minus 0.05mm keeps the wire position stable between passes, and trajectory accuracy below 0.4mm maintains the weave pattern along the seam.
• • Multi layer and intermittent welding functions are included in the process package, so pass sequences are stored as a schedule rather than taught point by point.
• • The SRC4S cabinet is IP54 rated with 24 digital and 4 analog channels, and it keeps the welding power source interface inside the same control system.
• • End linear velocity of 2.5 m/s and a fifty percent faster working speed reduce the non welding portion of each cycle.
• • Brake hold on power failure prevents the arm from dropping onto the workpiece during an unexpected stop in a heavy fabrication cell.

Specifications

Advantages

Why multi pass welding needs arc tracking

• • Arc tracking compensates for gap and mismatch variation along the joint.
• • Multi layer and intermittent welding schedules are stored in the controller.
• • 0.05mm repeatability and 0.4mm trajectory accuracy hold weave pattern position.
• • Hollow wrist keeps torch cable clear during vertical and overhead passes.
• • Fifty percent faster working speed reduces non welding cycle time.
• • SRC4S cabinet interfaces the welding power source inside one control system.
• • Twenty four digital channels cover torch, feeder and safety signals.
• • Brake hold on power failure protects the workpiece and fixture.

Applications

• • Medium and thick plate butt and fillet welding with multiple passes.
• • Pressure vessel and tank longitudinal seam welding.
• • Structural frame welding where gap variation is common.
• • Repair and rework welding with intermittent stitch patterns.
• • Welding cells with servo positioners and coordinated axes.
• • Stainless and carbon steel fabrication above 8mm plate.

FAQ

How does arc tracking help on thick plate joints?

Arc tracking measures the joint position while welding and offsets the torch in real time, so gap and mismatch variation between parts does not push the wire off the seam.

Can multi pass schedules be stored in the controller?

Yes. Multi layer welding is part of the process package, and each pass keeps its own torch angle, travel speed and weave settings inside a stored schedule.

Is intermittent welding supported for stitch seams?

Intermittent welding is included in the package, so stitch length and pitch are set as parameters instead of being taught point by point.

What accuracy does the robot hold between passes?

Repeatability is plus or minus 0.05mm and trajectory accuracy is below 0.4mm, which keeps the weave pattern and wire position stable across successive passes.

Can the cell run with a positioner?

Yes. The controller supports axes linkage and 4 to 8 additional axes, with the SRC4F cabinet driving up to 6 external axes from 400W to 5.5kW.
