TRUMPF introduces compact robotic laser welding cell

Key Takeaways

• TruLaser Weld 3000: a compact, AI‑driven laser welding cell unveiled at EuroBLECH 2026.
• Programming efficiency: AI‑assisted TeachLine and offline TruTops Weld cut setup time by up to 50 %.
• Optics shrinkage: welding optics are ≈ 40 % smaller, enabling access to deep‑drawn housings and tight cavities.
• Process capabilities: BrightLine Scan provides 0.4 mm gap‑bridging and motorized focus for variable‑thickness parts.
• User friendliness: touch‑screen TeachLine Touch lets operators of any skill level adjust weld points on‑the‑fly.

Overview of the TruLaser Weld 3000

At the EuroBLECH 2026 exhibition, TRUMPF launched the TruLaser Weld 3000, a robotic laser welding cell that packs a full‑size robot, high‑power laser source, and AI‑enabled software inside a 1.8 m × 1.2 m footprint. The enclosure is built from powder‑coated steel, meets IP‑65 protection, and can be positioned on a standard factory floor without additional shielding.

AI‑Assisted Programming from CAD Data

Offline & On‑Machine Workflow

The TruTops Weld software lets engineers import STEP or IGES CAD files and generate weld paths without stopping the production line. While the cell continues welding existing parts, programmers can:

1. Import geometry → automatic seam detection.
2. Apply TeachLine Touch – a 12‑inch capacitive screen where weld points can be dragged, rotated, or deleted.
3. Validate the program via a virtual simulation that flags collisions and excessive heat input.

When the operator is ready, the program is transferred to the cell via a secure Ethernet link in under 30 seconds.

TeachLine AI – Real‑Time Adaptation

TeachLine AI continuously scans the incoming workpiece with a high‑resolution 3‑D sensor. If the actual component deviates from the CAD model (e.g., a 0.2 mm shift in a joint), the AI recalculates the robot trajectory on the fly, preserving weld quality without manual re‑programming. TRUMPF’s internal tests show setup and programming time cut by 45–50 %, translating to an average 2‑hour reduction per batch on a typical 10‑part run.

Compact Optics & Advanced Process Functions

Miniaturized Welding Optics

The new optics module, at 40 mm diameter, is roughly 40 % smaller than the previous generation. This reduction permits the robot arm to reach inside deep‑drawn housings, crates, and multi‑layer boxes that were previously inaccessible without manual re‑orientation.

BrightLine Scan Technology

BrightLine Scan couples a high‑frequency galvanometric scanner with a motorized focus drive:

• Gap‑bridging: up to 0.4 mm (versus 0.25 mm on older cells).
• Focus range: 0–30 mm, automatically adjusted for varying sheet thickness.
• Laser power: 2 kW continuous wave fiber laser, delivering a peak power density of 1.5 MW cm⁻².

These capabilities enable reliable welding of thin‑walled automotive brackets and high‑precision medical device housings in a single pass.

User Experience & Safety

The cell’s control panel integrates a 12‑inch multi‑touch display running a customized Windows 10 IoT core. Operators can toggle between TeachLine Touch, process monitoring, and maintenance diagnostics without leaving the workstation. Safety interlocks meet EN ISO 13849‑1 Category 4 requirements, and the enclosure includes a built‑in laser safety curtain that automatically shuts down the laser if the door is opened.

Bottom Line

TRUMPF’s TruLaser Weld 3000 delivers a decisive leap in compactness, AI‑driven programming, and optical flexibility. By shrinking the welding optics by 40 % and embedding TeachLine AI, the system slashes programming effort by half while reaching previously inaccessible geometries. For manufacturers seeking to boost throughput on complex, low‑volume parts—especially in automotive, aerospace, and medical sectors—the 3000 model offers a future‑proof, user‑friendly solution that aligns with Industry 4.0 standards.
