Yantai Dongruitai Welding and Cutting Equipment Co., Ltd. is one of the leading manufacturers and suppliers of laser welding robot in China. We are committed to providing high quality customized machines with low price. Welcome to wholesale the newest laser welding robot made in China here from our factory. 1 years warranty is available.
As metalworking shifts from manual cutting to automated cell production, joint consistency and operational range are primary considerations. This 6-axis robot laser welding machine by Dongruitai Laser helps eliminate human error, reduces spatter, and enables repeatable deep-penetration welding on complex 3D contours.
The equipment features a hollow arm and wrist structure with all laser fibers, gas lines, and control cables internally routed. This prevents cable tangling during high-speed axis rotation, allowing the welding head to smoothly navigate tight internal corners and complex tubular components without mechanical interference.

Key Features & Operational Benefits
A. High-Dynamic 6-Axis Motion & Compact Wrist Engineering
- Hollow Structure Design: Internal routing protects high-flex robot cables from thermal radiation, mechanical friction, and splashes.
- Agile Axis Speed: Wrist rotation speed reaches up to 790°/s on the J6 axis, minimizing cycle time during torch reorientation between complex seam segments.
- Confined Space Accessibility: The streamlined outer arm geometry allows deep reach into narrow cabinets, structural frames, and pipe junctions.
B. Precision Positioning & Environmental Resilience
- ±0.05mm Repeat Accuracy: Serves as a high-precision automated laser welding machine capable of maintaining tight focal tolerances over long shift runs.
- IP54 Industrial Protection: Features IP54 rating for the main body and wrist, resisting ambient metallic dust and moisture on active shop floors.
- Flexible Installation Orientation: Supports floor mounting, inverted (ceiling mounting), or side wall mounting, and can be seamlessly integrated with existing workbenches or platform units.
Industry Applications
This industrial welding robot platform is designed for high-precision joint sealing and structural joining across diverse manufacturing sectors:
- Automotive and New Energy: EV battery enclosures, exhaust manifolds, automotive chassis parts, and aluminum alloy frames.
- Sheet Metal and Hardware: Kitchenware, stainless steel sinks, electrical enclosures, metal furniture, doors, windows, and guardrails.
- Heavy Machinery and Infrastructure: Engineering machinery structures, pressure vessels, pipelines, shipbuilding assemblies, and steel trusses.
- Medical and Precision Equipment: Stainless steel medical housings, food processing tanks, and high-purity piping systems.

Frequently Asked Questions
Q1: What are the main advantages of a 6-axis laser welding robot over manual handheld laser welding?
A: Robot automation ensures consistent travel speed, focus distance, and seam geometry, eliminating human variables. It can increase daily production by up to 300% while reducing scrap rates and operator labor costs.
Q2: Can this robot arm carry a laser welding head together with an automatic wire feeder?
A: Yes. With a rated wrist payload of 10kg, the robot comfortably carries heavy-duty wobble laser heads, wire feeding nozzles, and monitoring camera modules without exceeding torque limits.
Q3: Is the system compatible with different fiber laser power sources?
A: Absolutely. The platform can be integrated with fiber laser power sources ranging from 1.5kW to 6kW, depending on target material thickness and penetration requirements.
