SIASUN Industrial Robot Smart Welding Solutions For Ships

A ship's hull defies the logic of the production line. No two blocks are quite alike, plates arrive with gaps that vary along the seam, and the geometry changes from bow to stern. Robots, by contrast, have traditionally thrived on repetition. SIASUN Industrial Robot Smart Welding Solutions For Ships sets out to close that gap: rather than asking the shipyard to become more uniform, it gives the welding robot the means to see each workpiece, locate each seam and adapt its path as it works.

Robots Europa, based in Dublin, supplies SIASUN Industrial Robot Smart Welding Solutions For Ships to shipyards and marine fabricators across the European Union and the DACH region. Robots Europa prepares each quotation, coordinates delivery to your site and remains your point of contact for support once the system is in service.

Background

SIASUN and its automation portfolio

SIASUN is a Chinese robotics manufacturer whose range spans industrial robots, mobile robots and complete automation solutions for manufacturing. Alongside individual robot arms and autonomous handling vehicles, the company offers process-specific packages in which robots, sensing and software are brought together around a single production task. Shipbuilding welding is one of those packages, and it sits within a broader family of SIASUN welding offers that you can explore through the Welding Robots category.

Vision, process knowledge and CAD in one system

What distinguishes this solution is the way three layers work together. At the cell, robots are equipped with intelligent vision technology. Behind them sits an expert system database tailored to specific manufacturing processes, carrying the welding knowledge the robot draws on. Above both, an upper-level computer system interfaces with CAD drawings, so that the design intent of each part informs what happens on the shop floor. The result is a welding system built to cope with variety rather than to demand standardisation from the yard.

Technical Specifications

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

The manufacturer has not published the robot model used, the payload, reach or repeatability, the welding process types, the power requirements, the seam tracking accuracy, the scan area, the dimensions, the weight, the software names or what is included in the delivery; all of these are confirmed at quotation.

How does the system find and follow a weld seam on irregular ship parts?

The answer lies in a staged approach to positioning. The process begins with 3D structured light scanning, which rapidly captures three-dimensional information about the workpiece and automatically identifies the features of each weld seam. This shortens the preprocessing stage considerably, because the seams no longer have to be located and taught by hand before welding can begin.

Scanning alone establishes where the work is in broad terms. SIASUN therefore applies hierarchical positioning: a rough positioning over a large area through 3D scanning, followed by precise guidance and dynamic compensation of the welding gun at a fine scale, using point laser sensors and laser tracking. In practical terms, the system moves from an overview of the whole part to a close-up of the joint itself, correcting the torch position as it goes.

Once welding is under way, real-time seam tracking takes over. The system monitors the condition of the seam continuously and adjusts the welding path and posture according to actual changes in the joint. This is what makes the solution particularly suitable for complex shapes and irregular gaps, the very conditions that make shipyard welding difficult to automate with fixed programmes.

What does smart welding change for a shipyard?

The first change is throughput. Automating the welding reduces human intervention and increases the number of welding tasks completed per unit of time, which shortens manufacturing lead time across a project. Because seam identification is handled by scanning rather than manual teaching, the time between a part arriving at the cell and the first arc being struck is also reduced.

The second change concerns quality. The high precision and consistency of an intelligent welding system help reduce defect rates, which in turn improves the reliability and safety of the finished structure. For a yard, fewer defects mean less rework and fewer interruptions further down the build sequence.

The third change is in labour. The solution decreases the need for highly skilled welders, addressing both labour shortages and the challenge of training new welders to a high standard. Experienced staff can then concentrate on supervision, inspection and the joints that genuinely require their judgement.

Finally, there is flexibility. The system is designed to process non-standard workpieces of different sizes and shapes, which is precisely the profile of most shipbuilding work. Where a conventional welding cell rewards long series of identical parts, this solution is built around variety.

Who is SIASUN Industrial Robot Smart Welding Solutions For Ships for?

The primary audience is shipyards building or repairing vessels, where hull blocks, panels and structural assemblies combine long seams with changing geometry. Production managers facing tight delivery schedules and a shortage of qualified welders will find the combination of automated seam identification and adaptive tracking especially relevant.

Marine fabrication subcontractors, who supply sections and assemblies to larger yards, form a second segment. Their work is often a sequence of one-off or short-run parts, which suits a system intended for non-standard workpieces of different sizes and shapes.

A third group is engineering and digitalisation teams who want to link design and production more closely. The upper-level computer system interfacing with CAD drawings gives them a route from the drawing office to the welding cell.

Buyers whose requirement is a more general robotic welding cell, rather than a shipbuilding-oriented package, may also wish to review the SIASUN Arc welding robotic solution, or browse the wider Industrial Robots range. Robots Europa can help you compare the options against your production requirements.

What is SIASUN Industrial Robot Smart Welding Solutions For Ships used for?

1. Hull block welding – automating seams on large structural blocks whose geometry varies from one block to the next.
2. Panel and stiffener assemblies – following long joints where the gap may change along the length of the seam.
3. Non-standard structural parts – welding one-off workpieces of different sizes and shapes without lengthy manual teaching.
4. Complex joint geometries – adjusting path and posture in real time where seams curve or change direction.
5. Reducing preprocessing time – identifying weld seams automatically by 3D structured light scanning before welding starts.
6. Easing skilled-labour shortages – shifting repetitive welding to the robot so that experienced welders can focus on demanding work.

Frequently Asked Questions

What kind of parts can the system weld?

The solution is designed for non-standard workpieces of different sizes and shapes. It is particularly suited to seams with complex shapes and irregular gaps.

How does the robot know where the weld seam is?

It uses 3D structured light scanning to acquire three-dimensional information about the workpiece and automatically identify weld seam features. Point laser sensors and laser tracking then guide the welding gun precisely to the joint.

Can the system cope with gaps that change along the seam?

Yes. Real-time seam tracking monitors the condition of the seam and automatically adjusts the welding path and posture to actual changes in the joint.

Does it work with our CAD data?

The solution includes an upper-level computer system that interfaces with CAD drawings, linking design data directly to the welding cell.

Does the system shorten preparation before welding?

Yes. Because 3D structured light scanning identifies weld seam features automatically, the preprocessing stage becomes considerably more efficient than locating seams by hand.

Will it replace our welders?

The system decreases the need for highly skilled welders and reduces human intervention in repetitive welding. Experienced staff remain valuable for supervision, inspection and specialist joints.
