SIASUN Laser welding robotic solution (Laser welding robotic solution)

A laser can place energy on a seam with remarkable precision, yet the weld it leaves behind is only ever as good as the path the beam travels. In automated laser welding the robot is not simply a carrier for the tool; it is the hand that writes the seam. The SIASUN Laser welding robotic solution is built on that principle. Rather than fixing a laser to a general-purpose arm and leaving the rest to the integrator, SIASUN combines its own SR series industrial robot with the laser, the welding head, the wire feed and the cooling that the process depends on, and refines the motion control so that the whole cell behaves as one welding instrument.

Robots Europa, based in Dublin, supplies the SIASUN Laser welding robotic solution to manufacturers and system integrators throughout the European Union and the DACH region. Robots Europa prepares each quotation around the robot type and the application you have in mind, arranges delivery to your site and remains your point of contact for technical support once the system is in production.

Background

SIASUN and its SR series robots

SIASUN is a Chinese robotics and automation manufacturer whose portfolio extends from industrial and collaborative robots to complete application solutions for welding, grinding and handling. The laser welding system described here relies on the SR series, an industrial robot line that SIASUN developed independently. That detail matters more than it might first appear: when the manufacturer of the arm is also the author of the welding package, the dynamics model, the control algorithms and the application software can be shaped around one another instead of being reconciled after the fact.

SIASUN has continuously optimised the dynamics and control algorithms of this solution, improving trajectory accuracy, operating stability and transition performance under complex postures. For laser welding, where the beam must follow the joint closely through bends, corners and changes of orientation, those three qualities are precisely where a seam succeeds or fails.

A kit system rather than a collection of parts

The solution is presented as a laser welding kit system. Around the SR series robot it integrates the key components of the process: high-precision lasers, dedicated laser welding heads, automatic wire feeding equipment and water cooling systems. The welding machine is the MEGMEET Integrated Laser Welding Cell. Each of these elements has its own role. The laser supplies the energy, the dedicated head shapes and delivers it to the joint, automatic wire feeding adds filler material where the joint requires it, and water cooling keeps the laser and its optics within their working conditions during sustained operation.

On the software side, the system is equipped with a dedicated function configuration page and an application instruction set. In practice this means that welding functions are set up through a page designed for the task, and that programmers work with instructions written for laser welding rather than translating the process into generic motion commands. Digital communication between the components is designed to be stable and resistant to interference, achieving efficient and stable data transmission across the cell.

Technical Specifications

Specifications are as published by the manufacturer and are confirmed against the datasheet at quotation.

The manufacturer has not published the laser power, the laser type, the robot payload, the robot reach, the repeatability, the weight, the power supply, the dimensions, the IP rating or the welding head model; these are confirmed at quotation.

What makes a laser welding kit different from a robot with a laser attached?

Many laser welding cells begin life as two separate purchases: a robot from one supplier and a laser source from another, joined together by an integrator. That approach can work, but it leaves the hardest part of the job, making the motion and the process cooperate, to the final stage of the project. The SIASUN Laser welding robotic solution takes the opposite route. The robot, the laser, the dedicated welding head, the wire feed and the water cooling are supplied as one kit system, and the welding machine is a named, integrated cell from MEGMEET.

The benefit shows up in three places. First, motion quality: the robot holds high trajectory accuracy and remains stable at a high speed of 30mm/s, which is the kind of steadiness a narrow laser seam demands. Second, communication: the digital link between components is designed to resist interference, so that commands and process data arrive reliably. Third, programming: a dedicated configuration page and an application instruction set put the welding functions directly into the hands of the programmer.

Behind all three lies the process itself. Laser welding is a non-contact method, and it is flexible, controllable, environmentally friendly and efficient. Because nothing touches the workpiece, there is no electrode to wear and no contact force to manage, and the robot's job becomes purely one of guiding the beam with accuracy.

Which robot type should I choose: SR12A-12/1.46 or SR25A-25/1.80?

The solution is offered with two SR series robot types, the SR12A-12/1.46 and the SR25A-25/1.80. Both are listed as options for the kit without separate figures for each, and the 30mm/s stability statement applies to the robot in general rather than to one model. For that reason the choice between them is best made against your workpiece: the size of the parts, the layout of the cell, the orientations the welding head must reach and the fixtures it must work around.

When you request a quotation, Robots Europa will discuss these points with you and help you select the robot type that suits your production.

Who is the SIASUN Laser welding robotic solution for?

The system suits manufacturers who want to bring laser welding into series production without assembling the cell from scratch. Sheet metal fabricators, producers of enclosures and cabinets, and suppliers to the automotive and electrical sectors are natural candidates, as are workshops that weld visible seams where a neat, consistent finish matters. System integrators building turnkey cells for their own customers will also value a kit in which the robot, the laser components and the application software already belong together.

It is equally relevant to companies moving from manual welding to automation. The dedicated configuration page and application instruction set lower the barrier to programming, while the non-contact nature of the process reduces the number of consumable parts to manage.

Laser welding is not the answer to every joint, however. Where your production calls for conventional arc welding, the SIASUN Arc welding robotic solution addresses that process, and for resistance welding of sheet assemblies the SIASUN Spot welding solution is the relevant system. You will find further options in our Welding Robots category and across the wider range of Industrial Robots.

What is the SIASUN Laser welding robotic solution used for?

1. Sheet metal fabrication: joining panels and formed parts where a narrow, clean seam reduces rework.
2. Enclosures and cabinets: welding housings for electrical and industrial equipment in repeatable batches.
3. Automotive components: producing structural and trim parts on lines that demand consistent, traceable joints.
4. Visible seams: welding products whose joints remain on show and must look tidy without extensive finishing.
5. Wire-fed joints: bridging gaps with filler material supplied by the automatic wire feeding equipment.
6. Turnkey cell projects: giving integrators a coordinated laser welding package around which to build a complete cell.

Pricing and Availability

The cost of a laser welding cell depends on the robot type, the configuration and the requirements of your application, so Robots Europa prepares a quotation for each project rather than publishing a single figure. Tell us about your parts, materials, joint types and production volumes, and we will propose a configuration to match. Delivery, customs and support are arranged with the quotation, so you receive a single, complete proposal for the European Union or the DACH region.

Summary

In laser welding the beam is precise by nature; what decides the quality of the seam is the path it follows. The SIASUN Laser welding robotic solution treats that path as the heart of the system, pairing the independently developed SR series robot with high-precision lasers, dedicated welding heads, automatic wire feeding, water cooling and the MEGMEET Integrated Laser Welding Cell. Optimised dynamics and control algorithms, stability at a high speed of 30mm/s, interference-resistant communication and a dedicated application instruction set turn these parts into a single welding instrument.
