SIASUN Medium And Thick Plate Welding Machine Set

In SIASUN’s arc-welding portfolio, the “medium and thick plate” set is one of three primary categories—thin plate, medium and thick plate, and ultra-low spatter—reflecting different process priorities such as heat input control, spatter behavior, deposition rate, and robustness for heavier joints.

Although exact configurations vary by region and integrator, public product listings commonly describe this set using SIASUN welding-focused robots such as SR12A-12/1.46 and SR25A-12/2.01, paired with a digital welding power source (often cited as MEGMEET Dex2 series in configured packages).

Design and Features

Integrated “machine set” architecture

SIASUN describes its arc-welding kit systems as being centered around the SR series robot, equipped with an intelligent welding control system, integrated with digital welding equipment, and delivered in an integrated design to support professional, efficient, and stable welding.
This “set” approach is typically intended to reduce engineering complexity compared with assembling a cell entirely from separate components, and to provide a more standardized platform for scaling welding automation across lines or plants.

SR-series welding robot platform

Two robot models frequently associated with SIASUN’s welding-oriented deployments are:

• SR12A-12/1.46: Described by SIASUN as being specifically developed for demanding arc-welding applications, emphasizing high precision and stability. It uses a hollow bow-shaped arm enabling internal cabling and includes a wire feeder integrated into the robot body to improve wire-feeding stability. Key published parameters include 12 kg payload, 1465 mm reach, and ±0.03 mm repeatability (repeat positioning accuracy).

• SR25A-12/2.01: Described as incorporating a streamlined hollow bow-arm design to reduce interference with workpieces and support compact layouts, with a built-in welding cable system to reduce external wear and support wire-feeding stability. SIASUN lists 12 kg payload, 2010 mm reach, and ±0.07 mm repeatability.

These attributes are relevant to medium and thick plate welding because heavier joints often involve larger assemblies, more constrained access, and longer weld paths—where stable motion, consistent torch orientation, and robust cable management can materially affect weld consistency and uptime.

Digital welding power source integration

Medium/thick plate welding systems commonly require high duty-cycle performance and flexible process control to handle deeper penetration, larger fillets, and multi-pass procedures. Public configurations frequently cite integration with MEGMEET Dex2 series welding power sources in robotic setups.
MEGMEET’s Dex2 product documentation also highlights that with a robotic accessories package, a manual-type power source can be expanded for robotic welding—underscoring the common industry pattern of configuring standardized power sources for automation contexts.

Production functions for thicker joints

For medium and thick plate work, weld quality and yield often depend on consistently placing the bead despite part variation or thermal distortion. Public listings for SIASUN welding configurations commonly reference optional or supported functions such as:

• Seam finding

• Weld seam tracking

• Multi-pass welding capabilities

• Additional workflow features like breakpoint recovery (helpful for recovering after stoppages)

These capabilities are especially relevant when joint location is not perfectly repeatable, or where multi-pass procedures require consistent bead placement from pass to pass.

Technology and Specifications

System components (category-level description)

At the category level, SIASUN describes its arc-welding kit systems (including the medium and thick plate set) as:

• Built around an SR-series industrial robot

• Equipped with an intelligent welding control system

• Integrated with digital welding equipment

• Delivered in an integrated design for professional, efficient, and stable welding

Representative robot specifications (published by SIASUN)

While the welding “set” is a system, robot specifications are often the most consistently published, since they define payload, reach, and repeatability:

• SR12A-12/1.46: payload 12 kg, reach 1465 mm, repeatability ±0.03 mm, wrist protection IP65

• SR25A-12/2.01: payload 12 kg, reach 2010 mm, repeatability ±0.07 mm, wrist protection IP65

Typical cell-level engineering (often project-specific)

In practical deployments, overall “system specs” typically include items that are determined during integration:

• Workholding and fixtures suited to thick plate assemblies

• Safety guarding and interlocks

• Positioners/turntables for access to multiple sides of large parts

• Torch cleaning/reaming stations (depending on consumables strategy)

• Offline programming workflow and quality checkpoints

These factors often drive real-world productivity and quality as much as the robot or power source selection.

Applications and Use Cases

SIASUN positions welding automation broadly across industries including engineering machinery, ship-related applications, and automotive manufacturing, among others.
Within that context, medium and thick plate welding machine sets are commonly used for:

• Engineering and construction machinery: structural brackets, frames, booms, and heavy welded subassemblies (where multi-pass welds and consistent geometry matter).

• Shipbuilding and large fabrication: selected subassemblies and structural components, where long welds and positional constraints favor robotic repeatability.

• Automotive and transport equipment: jigs and fixtures support repeatable welding on thicker mounts and structural parts in specialized vehicle production.

• General metal processing and heavy fabrication: medium-to-thick plate assemblies that benefit from stable arc performance and standardized process recipes.

Advantages / Benefits

Standardized, integrated deployment

SIASUN emphasizes an integrated kit design—robot, control, and digital welding equipment—intended to make welding operations “easier, more precise, and more efficient” at the solution level.
For buyers, this can translate into quicker specification, fewer interface uncertainties, and a more consistent commissioning approach across projects.

Welding-focused robot mechanical and cabling design

Both SR12A-12/1.46 and SR25A-12/2.01 highlight internal cabling features and integrated wire-feeding considerations, designed to reduce interference and improve wire-feeding stability—important for uptime and weld consistency in production.

Support for tracking and multi-pass workflows

Public configurations commonly reference seam finding/tracking and multi-pass capabilities, which align with thick plate realities: joint variability, distortion across heat cycles, and the need for consistent bead placement over multiple passes.
