Steel structure welding cobot, This ensures consistent quality in structural steel production. In steel construction, every faulty seam means rework, project delay penalties, and engineering revisions. With ESAB Aristo 500ix + ROKAE CR12, repeatable penetration throughout the series in multi-pass section welding — the first time, every time.

— The reality of the industry —
In steel construction
The error carries a structural risk.
Beams, columns, roof trusses — all subject to NDT testing and engineering approval. One failed stitch can halt a project, incur penalties, and damage reputation.
Source failed in NDT test.
Ultrasonic or radiographic testing reveals porosity, cold overlay, and insufficient penetration. The entire production line stops, and rework begins again — a loss of both cost and time.
Inconsistent penetration and multiple pass errors.
In thick profiles, each pass is welded with a different heat input. When the bonding between passes is defective... The structural strength turned out to be lower than calculated.
Project schedule printing
Steel structure projects are linked by an assembly chain. Welding delays affect the entire site. Delivery penalties are calculated daily; each stop represents a direct monetary loss.
I can't find a welder for thick profiles.
HEA, HEB, and box profile welding requires specialized skills. The number of welders with this experience is decreasing. The pay is high when you find it, but the line stops when you leave.
Human error in repeated stitching.
Hundreds of identical joints, hundreds of identical seams. The welder gets tired, his concentration drops. The final pieces in the series don't maintain the same quality as the beginning ones.
Rework costs and waste.
Thick profile steel is an expensive raw material. Grinding, re-welding, and re-NDT are required for faulty seams. The true cost of a faulty connection point is five times higher than it appears.
From these problems at least 3 of them Is this happening on your line as well?
Each of these can be solved with repeatable resource systems.

For heavy manufacturing
designed system.
500A. Multiple passes. Under field conditions.
ESAB Aristo 500ix is an industrial pulse power unit developed for the demanding conditions of structural steel fabrication. QSet™ intelligent parameter system Regardless of operator experience, it finds the correct arc parameter. More than 250 pre-configured synergy lines are instantly activated for different profile thicknesses. ROKAE CR12 produces long corner seams and repetitive connection points with a deviation of ±0.03mm, 24/7. Result: A verifiable, repeatable source that passed the first NDT test.
The system learns the parameter once,
It produces the same stitch throughout the series.
It produces the same stitch throughout the series.

— Operational Process —
From installation to production
3 steps.
A dedicated software engineer is not required for a lengthy integration project. It is managed at the workshop operator level and enters the production line in 5 days.
01
Select Profile & Thickness
Select the material type and section thickness. Aristo 500ix has over 250 ready-made synergy lines. QSet™ automatically adjusts the DC current, wire speed, and arc voltage for HEA, HEB, box profiles, sheet metal, and pipes. QSet™ optimizes the arc characteristics — no parameter trial from scratch.
02
Teach the Robot Throughout the Sewing Process
Hold the ROKAE CR12 and move it along the weld line. Ghost Teaching technology It records long corner seams and repetitive connection points in 15 minutes. For multi-pass welding, each pass is saved as a separate program.
03
Produced — Each Part Ready for NDT.
The robot welds each connection point with the same heat input, at the same speed, and in the same number of passes. SCT (short circuit termination) It ensures flawless seam finishing, eliminating crater cracking. A quality control certificate is automatically generated.
QSet™ — No Master Required
The QSet™ intelligent system optimizes the arc parameter regardless of operator experience. The right resources from day one, zero trial and error.
Documentable Quality
The recorded parameters can be monitored for each component. Source data can be submitted as documentation before NDT and during the engineering approval process.
Multi-Pass Welding Consistency
Each pass is executed in the registered sequence and with the same parameters. Interpass bonding defects are eliminated, and penetration remains constant throughout the series.
Durable for field conditions.
The IP23 power supply unit and IP67 robot — both operate flawlessly in open field and factory environments. The mobile platform can be freely positioned within the production area.
— Target Audience —
For whom?
the right choice?
Performing repetitive structural stitching, operating under NDT pressure, and adhering to delivery schedules. Every manufacturer who wants to eliminate rework costs.
01
Steel Structure Manufacturers
Industrial buildings, roofing systems, steel frame manufacturers. For hundreds of identical connection points, a robot is the perfect solution — repetitive stitching is the ideal workload for a robot.
02
Bridge & Infrastructure Contract Manufacturers
Bridge girders, bridge underpasses, tubular bridges. In structures requiring high strength. Documentable source quality accelerates engineering approval.
03
Industrial Equipment & Machine Housings
Press, crane, construction equipment chassis, industrial tank. Consistent penetration and clean seam in thick sheet metal and profile welding., It directly affects assembly tolerance and lifespan.
04
Agricultural & Construction Machinery Manufacturers
Frame, cabin, harness, boom. In structures operating under high vibration, the quality of repeated stitching is directly related to safety and warranty costs.

Manual welding,
Registered system?
Variability is unacceptable in structural steel. The system welds each connection point with the same parameter — the welder gets tired, the robot doesn't.

— Cost Analysis —
NDT rejections
the cascading cost it creates,
from what is visible
much heavier.
In steel structure manufacturing, a faulty weld seam instantly quadruples operational costs through regrinding, repeated NDT tests, engineering revisions, and on-site delivery delays. Furthermore, transporting heavy steel profiles to a stationary robot is a massive waste of time. With the Astoryas ROKAE mobile welding cell, take the robot to the job, not the part — guarantee your NDT success rate by achieving flawless penetration the first time.
