SIASUN Xinsong Medium And Heavy Plate Welding Machine System

On thick plate, a weld is rarely a single event. A joint may need a root run, several fill passes and a capping pass, and each one inherits the position, heat and accuracy of the pass before it. A slight wander in the first run becomes a visible fault by the last. The SIASUN Xinsong Medium And Heavy Plate Welding Machine System is designed for that cumulative challenge. It places SIASUN's own SR-series industrial robots at the centre of a set that also comprises a next-generation intelligent welding control system and digital welding equipment, so that the final pass on a long seam is laid with the same discipline as the first.

Robots Europa, based in Dublin, supplies this welding set to manufacturers throughout the European Union and the DACH region. Each quotation from Robots Europa is prepared around your intended configuration, covering the robot model, the torch and the welding equipment. We remain your point of contact for delivery, technical questions and after-sales support once the set is installed in your workshop.

Background

SIASUN and the Xinsong name

SIASUN, known in Chinese as Xinsong, is a robotics and automation manufacturer whose portfolio extends from individual industrial robots to complete production solutions. Both names appear on this product, and they refer to the same company. What matters for a welding buyer is that the manipulators in this set are not bought in from a third party. The SR-series robots are developed by SIASUN itself, which means the arm, its motion control and the welding package around it come from a supplier that designs the core of the cell rather than simply assembling it.

A robot-centred approach to plate welding

The set is organised around the robot rather than around the power source. The SR-series arm guides the torch, and an intelligent welding control system coordinates its path with the digital welding equipment. Smart welding software supplies the routine functions that plate work depends on: position sensing detection to locate the joint, seam tracking to follow it, and multi-pass welding to build up the joint in layers. The aim is low-spatter, smooth welding with even bead deposition and a clean transition at the edges of the weld. The set handles carbon steel, low-alloy steel, stainless steel and aluminium alloys, which gives fabricators the flexibility to move between production tasks without changing the basic cell.

Technical Specifications

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

The manufacturer has not published the welding thickness range, the power source and robot controller model for this specific set, the controller power supply, the total system weight, the package contents or the payload rating for each robot version; these are confirmed at quotation.

How does a welding machine set differ from a standalone welding robot?

A standalone welding robot is an arm with a torch mount. It still needs a power source, a wire feed, a torch, a control strategy and software that knows what a weld joint is. Assembling those elements from different suppliers is entirely possible, but every interface between them becomes a point where something can drift out of step, and every fault raises the question of whose component is responsible.

This SIASUN set approaches the task the other way round. The robot, the intelligent welding control system and the digital welding equipment are integrated as one package, and the welding software is part of that package rather than an afterthought. On medium and heavy plate this has practical consequences. Position sensing detection allows the robot to find the actual joint rather than relying solely on the programmed one, which matters when cut plates and tack-welded assemblies are never perfectly identical. Seam tracking keeps the torch on the joint along its length. Multi-pass welding lets the programme build a thick joint in controlled layers instead of attempting it in a single heavy run. Together these functions address the variability that makes plate welding difficult to automate.

Which welding power source and torch does the set use?

Two welding machines are named for this set. SIASUN's own arc welding solution names the Aotai MAG-350Pro RII-Plus. A reseller listing for the set names the Dex2 500MPR, with a rated output current of 500A and a power source weight of 40 kg. Robots Europa specifies the welding machine for your set in writing as part of the offer.

The torch is a genuine choice. Three options are named: the Loyee GL350N-HDA, the TRM 352P and the ARH6350. Which one suits your work depends on your joints, your wire and your duty cycle, and it is a decision best made together with the rest of the configuration rather than in isolation.

Who is the SIASUN Xinsong Medium And Heavy Plate Welding Machine System for?

The set is aimed at manufacturers whose welding work is dominated by thicker sections and long or repeated seams. Steel structure fabricators producing beams, columns and brackets form one natural group. Builders of heavy machinery, frames and chassis form another, as do producers of agricultural, construction and handling equipment where welded plate carries structural loads. Workshops that alternate between carbon steel, low-alloy steel, stainless steel and aluminium alloys will value a set intended to handle all of these materials.

The choice between the two robot models depends on reach and the size of your parts, and we recommend discussing your largest workpiece with us before deciding. Buyers whose production is mainly thin material may wish to compare this set with the SIASUN Sheet Metal Welding Machine Set. Shipyards and marine fabricators can review the SIASUN Industrial Robot Smart Welding Solutions For Ships, and operations producing frequently changing small batches may find the SIASUN Teach-Free Welding Robot worth considering. The wider range can be found under Welding Robots and Industrial Robots.

What is the SIASUN Xinsong Medium And Heavy Plate Welding Machine System used for?

1. Steel structures: welding beams, columns, gussets and connection plates for buildings and industrial halls.
2. Heavy equipment frames: joining the load-bearing plate sections of construction, mining and agricultural machinery.
3. Multi-pass joints: building up thick joints in controlled root, fill and capping passes.
4. Variable assemblies: using position sensing and seam tracking where cut and tacked parts differ slightly from piece to piece.
5. Stainless and aluminium components: producing smooth, low-spatter welds on stainless steel and aluminium alloy parts.
6. Series production of welded plate: replacing repetitive manual seams with a consistent, programmable process.

Pricing and Availability

The SIASUN Xinsong Medium And Heavy Plate Welding Machine System is supplied on quotation, because the final set depends on your choice of robot model, torch and welding equipment, and on the parts you intend to weld. Send Robots Europa a brief description of your workpieces, materials and joints, and we will return a quotation with the configuration suited to your parts. Delivery, customs and support are arranged with the quotation. A quotation for your configuration can be requested through the enquiry form available on this page.

Summary

Heavy plate welding is a test of consistency, because every pass builds on the one before. The SIASUN Xinsong Medium And Heavy Plate Welding Machine System meets that challenge with SIASUN's own SR-series robots, an intelligent welding control system and software that locates the joint, follows the seam and builds it in layers across carbon steel, low-alloy steel, stainless steel and aluminium alloys. Robots Europa agrees the robot model, torch and welding equipment with you before you commit. For a fabricator in the EU or the DACH region looking to make long, thick seams repeatable, this page is the starting point.
