It's Not the Robot. It's the Software.
From offline programming to weld data traceability: six technology layers that form the cell's intelligence.
Offline Programming (OLP)
Robot programs are prepared on the cell's digital twin without stopping production. Weld paths are derived from CAD; collision and reach are validated virtually.
- STEP / IGES CAD import
- Brand-agnostic robot code generation
- Reach and collision analysis
Laser Scanning & Adaptive Welding
Pre-weld laser scanning measures the part as built and the scan path is simulated on screen in real time. From that measurement the software automatically recomputes pass count, pass sequence and welding parameters; no manual programming. Even when heat distorts the part mid-weld, laser tracking keeps the torch aligned to the shifting joint; with no reprogramming, the robot welds the real part in front of it rather than the theoretical model.
- Weld groove geometry measurement
- Root gap and misalignment detection
- Path offsetting against the real part
Seam Tracking
The sensor watches the joint ahead of the torch throughout the weld; deviations caused by thermal growth and fixture tolerance are corrected live. Even if the part bends or shifts slightly, the robot is never reprogrammed; the weld path stays true from start to finish on long seams.
- Optical seam tracking sensors
- Arc-glare-resistant filtering
- Tack-weld skipping algorithms
Cell Management
The entire cell is run from a single operator panel; part recipe, program selection, safety state and fault diagnostics are gathered on one screen. On a product change the operator picks a stored recipe instead of writing a new program, and on a fault the panel shows the source separately (robot, PLC, power source); troubleshooting starts without waiting for a service visit.
- Part recipe and variant management
- PLC / robot / power source integration
- Remote diagnostics link: performance data and log access for pre-diagnosis before a site visit
Weld Data & Traceability
ArcTab makes the robotic welding operation visible: live welding data, program and weld history, operator performance and period comparisons in one platform.
- Live robot status and active program tracking
- Real-time current, voltage, wire feed and travel speed
- Per-seam parameter logging
Parametric Robot Programming
No separate program is written for each size in a product family. The operator enters the dimensions and the robot program is generated from them.
- Weld path defined as a function of dimensions
- Parameter entry from the operator panel
- Pass count computed automatically from thickness

From Site Survey to Service: 11 Steps
-
Site Survey
Layout, part flow and utilities are surveyed on site.
-
Welding Trials
Sample welds are run on your actual parts.
-
3D Simulation
Cell layout and cycle time are validated virtually.
-
Quotation
Scope, schedule and acceptance criteria are defined.
-
Design
Mechanical, electrical and software design under one roof.
-
Manufacturing
The system is fabricated and assembled at Robentex.
-
FAT
Factory acceptance testing runs on your real parts.
-
Site Installation
The system is shipped, installed and calibrated on site.
-
Commissioning
Commissioned under production conditions with welded-part acceptance.
-
Operator Training
Your team is trained in operation, maintenance and programming.
-
Service
Spares, maintenance and field support keep the system running.
Single Supplier. Single Responsibility.
In robotic welding projects the trouble rarely sits in the machine; it sits in the gaps between suppliers: the robot from one company, the fixture from another, the software from a third. When the part fails, everyone points elsewhere. At Robentex every step, from the welding procedure to field service, belongs to the same team.
Robentex
One responsibility-
Project ownership
One contract, one owner: mechanics, electrics, robot, welding procedure and software in one team.
-
Welding engineering
WPS/WPQR, process selection and joint design are done in house; the automation is built on those decisions.
-
Acceptance testing (FAT)
The system passes acceptance testing at our facility on your real parts before it ships.
-
Operator training
Your welder is trained on site after installation, to the point of running the robot alone.
-
Service & spare parts
The service team and critical spares are in Türkiye; response is planned from the same country.
Multi-supplier model
Split responsibility-
Project ownership
Robot, fixturing and software sit in separate contracts; the work in between belongs to no one.
-
Welding engineering
The welding procedure is outsourced to consultants; when scrap appears, accountability splits.
-
Acceptance testing (FAT)
Acceptance is usually run on representative parts; surprises surface during commissioning.
-
Operator training
Training is scattered across suppliers; dependence on an external programmer remains.
-
Service & spare parts
The service engineer and the part are awaited from abroad; downtime stretches.
