SIASUN Xinsong Medium And Heavy Plate Welding Machine System

A single weld on thick plate is never really a single weld. The root run, the fill passes and the cap each depend on the one before, so a fabricator needs a cell that repeats itself exactly, hour after hour. The SIASUN Xinsong Medium And Heavy Plate Welding Machine System is built around that need: SR-series robots, a digital welding package and smart welding software working as one set.

The product is available through this page, by quotation.

Background

SIASUN and the SR-series robots

SIASUN is a Chinese robotics and automation manufacturer, and the SR series is its own industrial robot family. This welding set is centered on SR-series robots that SIASUN developed independently. That matters to a buyer because the arm, the welding control and the software come from one design line rather than being pieced together from unrelated parts.

Two robot models are offered with the system: the SR12A-12/1.46 and the SR25A-12/2.01. Both carry the same wrist protection, the same maximum speed on the sixth axis and the same maximum payload figure. The specification table sets the two models side by side so that each figure stays with its own model.

Positioning of the system

The set combines a next-generation intelligent welding control system with state-of-the-art digital welding equipment. Its software covers position sensing detection, seam tracking, multi-pass welding and other routine functions. Together these point to one job: joining medium and heavy plate with long seams and several passes, where hand welding tires the operator and tests the consistency of the work.

The set delivers low-spatter, smooth welding on carbon steel, low-alloy steel, stainless steel and aluminum alloys. The aim is even bead deposition and a clean transition at the bead edge, so that the finished joint looks as good as it performs.

What makes this system different from a standalone welding robot?

A robot arm on its own moves a torch. A welding system has to do more: hold the arc steady, find the joint, and carry a weld through several passes without losing its place. This set is a complete arrangement of robot, welding equipment and software, so the parts work together.

The software list shows this most clearly. Position sensing detection lets the cell locate the joint rather than trust that the plate sits exactly where the program expects. Seam tracking follows the joint during welding. Multi-pass welding handles the layered work that thick plate demands. These are the functions a fabricator reaches for when parts come in with the normal variation of cut and fitted plate.

The torch choice is also left open. Three options are available, the Loyee GL350N-HDA, the TRM 352P and the ARH6350, so a workshop can match the torch to its own habits and spares.

How do the two robot models compare?

On the figures given, the SR12A-12/1.46 and the SR25A-12/2.01 are identical: both carry a maximum payload of 12 kg, both have IP65 wrist protection and both reach 720°/s on the J6 axis. The model codes differ after the slash.

The practical advice is to state your joint geometry, your part size and your cell layout when you request a quotation. We will then help you choose the model that fits your workpiece.

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

The system suits fabricators who weld plate in volume and need the same result on the hundredth part as on the first. Steel structure shops, heavy equipment builders, shipyard module producers and makers of large machinery frames all face long seams and multi-pass joints, and these are the settings where an automated set earns its place.

It also suits workshops that work across materials. Carbon steel, low-alloy steel, stainless steel and aluminum alloys are all named, so a shop with mixed work does not have to buy a different cell for each job.

If your work is lighter, a related set may serve you better. The SIASUN Sheet Metal Welding Machine Set is the sibling for thin material, and the SIASUN Medium And Thick Plate Welding Machine Set is the closely related plate offering. For ship work, see the SIASUN Industrial Robot Smart Welding Solutions For Ships. You can also browse the Welding Robots category or the wider Industrial Robots range.

For island fabricators, the appeal is steady output from a skilled team. Automation does not replace the welder's judgment; it lets that judgment be written into a program and repeated reliably.

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

1. Steel structure fabrication. Long seams on beams, plates and frames, welded in repeatable passes.
2. Heavy equipment manufacturing. Thick-section joints on machine bodies and structural parts that call for several passes.
3. Shipbuilding modules. Plate joints on hull sections and blocks, where consistency across many parts counts.
4. Large machinery frames. Strong, even beads on bases and frames that carry heavy loads.
5. Stainless steel and aluminum alloy work. Low-spatter welding on materials that show every flaw in the finish.
6. Mixed-material production. One cell handling carbon steel, low-alloy steel, stainless steel and aluminum alloys across different orders.

Summary

Thick plate rewards patience: each pass builds on the last, and one small drift can spoil a joint. The SIASUN Xinsong Medium And Heavy Plate Welding Machine System answers that with SR-series robots, digital welding equipment and software for position sensing, seam tracking and multi-pass work, across steels and aluminum alloys.
