SIASUN Spot welding solution (Spot welding solution)

On a welding line, the costliest hours are rarely the hours spent welding. They are the weeks spent teaching points, adjusting gun angles and chasing collisions on the shop floor while production waits. The SIASUN Spot welding solution (Spot welding solution) is designed to move much of that work off the floor and into a virtual cell. The robot, the spot welding gun, the controller and the water-gas supply are planned and commissioned in software first, so the physical installation confirms the plan rather than discovering its problems.

Robots Middle East sells the SIASUN Spot welding solution and supplies it to manufacturers, system integrators and fabrication plants across the Middle East. Our team prepares each quotation around your parts, your line layout and your process equipment, coordinates delivery to your site and remains your point of contact for technical support once the cell is in production. The solution sits within our wider Welding Robots range.

Background

SIASUN and its approach to industrial automation

SIASUN is a robotics and automation manufacturer that builds industrial robots and supplies them as complete process solutions rather than as bare arms. The spot welding package belongs to that family of integrated offerings, alongside solutions for arc welding, laser welding and grinding. The common thread is that the robot, its controller and the process know-how arrive together, with the aim of reducing the integration effort that normally falls on the customer or the integrator.

For this package, SIASUN equips the robot with a new generation of intelligent control systems, developed in-house for complex working conditions. The spot welding function package is also SIASUN's own development, giving precise control of welding parameters and monitoring them in real time. Because the products are highly standardised, both integration and delivery become more efficient, and project delivery cycles are shortened significantly.

Built for offline programming and virtual commissioning

The defining technology of this solution is its support for PDPS offline programming and virtual commissioning. In automotive and sheet-metal production, PDPS-based planning is a familiar way of laying out weld points, robot paths and cell sequences on a digital model before any hardware is installed. A spot welding cell that works natively with that workflow lets engineers validate reach to the weld points, check gun access and refine sequences while the equipment is still on its way.

SIASUN pairs this with a dedicated spot welding function configuration page and an application instruction set. Together they shorten on-site commissioning time, and the solution adapts to various brands of process equipment, so a plant can keep the welding guns and controllers its maintenance teams already know. The result is rapid deployment and delivery, and the flexibility to meet the differing welding requirements of different customers.

Technical Specifications

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

The manufacturer has not published the reach, repeatability, weld cycle time, power requirements, robot weight, IP rating, controller model, software version or a full list of package contents, nor a payload figure for the SR220A-220/2.65; these are confirmed at quotation.

Which robot should I choose: SR210A-210/2.65 or SR220A-220/2.65?

The solution is offered with two robot types, the SR210A-210/2.65 and the SR220A-220/2.65. For the SR210A-210/2.65, the payload is 210 kg (463 lbs), which is the figure to work from when sizing the robot against the spot welding gun you intend to use, together with its cables and any dress pack. A spot welding gun is one of the heavier tools an industrial robot commonly carries, so payload margin matters for path accuracy and long-term wear.

If your gun is at the heavier end, or you expect to change gun type during the life of the line, Robots Middle East will compare both robots against your gun weight and weld-point layout before recommending one. The choice is best made on your actual tooling and part geometry rather than on model codes alone.

How does virtual commissioning shorten a spot welding project?

In a conventional project, robot paths are taught on site, often after the fixtures, conveyors and safety guarding are already in place. Every collision found at that stage costs line time. With PDPS offline programming, the weld-point list, robot positions and sequences are built and checked in simulation, and virtual commissioning tests the cell logic before the hardware is energised.

The SIASUN solution is designed for this approach from the start. Its dedicated configuration page and application instruction set mean that much of the spot welding set-up is handled through standard tools rather than custom code, and its standardised components reduce the variation that typically slows integration. On site, the team's job shifts from building the programme to verifying and fine-tuning it, which is how the solution shortens on-site commissioning time and the overall delivery cycle.

Who is the SIASUN Spot welding solution for?

The primary buyers are vehicle and component manufacturers running body-in-white or sheet-metal assembly, where resistance spot welding joins pressed steel panels at high volume. Plants that already plan their lines digitally will gain most from the PDPS support, because their simulation work carries straight through to commissioning.

System integrators form the second group. A standardised cell with a dedicated spot welding instruction set and compatibility with various brands of process equipment lets an integrator reuse engineering across projects and deliver more predictably. Fabricators of cabinets, enclosures, appliances and steel structures that join sheet metal by spot welding are a third segment, particularly where they are moving from manual welding guns to automation.

Spot welding is not the right process for every joint. Where you need continuous seams on thicker sections, the SIASUN Arc welding robotic solution is the better starting point, and where narrow, low-distortion seams matter, consider the SIASUN Laser welding robotic solution. The full SIASUN line-up is available in our Industrial Robots category.

What is the SIASUN Spot welding solution used for?

1. Body-in-white assembly: joining pressed steel panels into floor, side and roof assemblies on automotive lines.
2. Sheet-metal subassemblies: welding brackets, reinforcements and closures for component suppliers.
3. New line projects planned in PDPS: carrying simulated weld paths straight into commissioning.
4. Line expansion and retrofit: adding robotic spot welding stations while keeping existing guns and controllers.
5. Multi-variant production: handling different weld programmes for several part variants on the same cell.
6. Fabrication automation: replacing manual spot welding of enclosures, cabinets and appliance housings.

Summary

The value of the SIASUN Spot welding solution lies less in any single component than in how much of the project it allows you to finish before the equipment arrives. PDPS offline programming and virtual commissioning, a standardised cell, an in-house spot welding function package and compatibility with various brands of process equipment all work towards the same goal: a shorter, more predictable path from plan to production. With the SR210A-210/2.65 and SR220A-220/2.65 to choose from, and Robots Middle East handling quotation, delivery and support, the remaining step is matching the robot to your welds. For any spot welding project in the region, this page is the starting point.
