Robotic Laser Welder: Case Study

A Tier 1 automotive supplier replaced manual TIG welding for high-strength exhaust components with Klear’s robotic laser system. Previous processes took 15 hours per batch with frequent rework due to warping and inconsistent penetration. The shift to automation streamlined production while meeting strict OEM quality standards.

Traditional TIG welding relied on skilled labor and generated excessive heat. This caused 18% defect rates and required post-weld grinding that added 25% to costs. Joint alignment issues further reduced throughput and consistency across shifts.

Klear’s system uses a Raycus 3000W fiber laser source with adaptive wobble welding heads. It achieves 55 cm/min speed and 9mm penetration depth. Dynamic beam control eliminates misalignment errors and reduces heat input by 60% compared to manual methods.

Cycle times dropped by 62% across all production lines. Labor costs decreased by 58% as one operator now manages three robotic units simultaneously. The system’s energy efficiency also cut electricity usage by 35% annually.

Real-time process monitoring ensures zero defects during 24/7 operations. The client now produces 1,200 parts daily with no post-weld finishing required. This transformation met ISO 14001 sustainability targets while increasing output capacity by 200%.

Principais caraterísticas e vantagens

Klear Laser couples JPT’s 4-kW MOPA engine with a high-dynamic wobble head that swings the beam in a programmable 0-5 mm pattern.

This pair delivers 4 mm penetration in 316 L yet lets you dial the spot size down to 50 µm for hair-line precision work.

Because the wobble frequency is independent of the robot speed, you get a satin-smooth, porosity-free seam at travel rates up to 2 m min⁻¹ on 2 mm aluminum—no post-grind needed.

The head is our own double-wobble unit: water-cooled copper mirrors, collimation zoom 75-200 mm, and a protected ZnSe window rated for >10 kW back-reflection.

Inside, a magnetic encoder reports real-time mirror angle to the robot controller with 0.02° repeatability, so every overlap stitch lands within 30 µm even when the sixth axis flips 180°.

That closed-loop feedback is why automotive seat-belt retractor lines switched from resistance to our cells—zero spatter, zero downtime, 18 month ROI.

Every head ships with a consumables kit—nozzle, cover glass, and calibration target—so your production line is welding within two hours of forklift delivery.

Aplicações industriais

Robotic laser welding represents the pinnacle of industrial automation by combining high-speed robotics with advanced fiber laser sources. At Klear Laser, we integrate top-tier JPT and Raycus laser sources to ensure consistent energy delivery for heavy-duty production cycles. This synergy allows for precise seam tracking and rapid processing speeds that far outpace manual TIG or MIG operations.

The automotive sector relies heavily on robotic laser welding for the assembly of chassis components and battery packs for electric vehicles. The deep penetration capabilities of our systems allow for the joining of high-strength steel and aluminum without compromising structural integrity. Furthermore, the localized heat input minimizes the heat-affected zone (HAZ), preventing thermal distortion in thinner body panels.

In aerospace manufacturing, precision and weight reduction are paramount for flight hardware. Our robotic systems utilize advanced wobble welding heads to manipulate the beam geometry, allowing for excellent gap bridging on complex titanium and superalloy parts. This technology ensures hermetic seals on fuel lines and sensor housings where traditional welding methods often fail to meet stringent quality standards.

The marine industry benefits significantly from the ability of robotic laser welders to process thick carbon and stainless steel plates used in hull construction. The consistent bead profile achieved by automation reduces post-weld grinding and enhances corrosion resistance in saltwater environments. By replacing older arc welding techniques, shipbuilders achieve higher throughput and stronger joints capable of withstanding extreme maritime stresses.

Klear Laser is committed to transforming industrial manufacturing by providing clean and efficient alternatives to polluting legacy processes. Our robotic solutions offer a pathway to higher productivity and superior weld quality for forward-thinking manufacturers.
