Visual Components Robotics OLP (previously Delfoi ARC 4) is fast and user-friendly remote programming software for main robot brands. Software utilizes CAD-models and integrated WPS (Welding parameter database) for high-quality welds.

One Software For All Processes
With Visual Components Robotics OLP (Offline Robot Programming) software you can program robots to do precise welds, buffs, grinds, cuts or paints.
The software is the result of more than 20 years of intensive development work together with our customers to fulfill even their most demanding needs. The trail blazing Visual Components Robotics OLP software for offline programming of arc welding robots has won all benchmarks when measuring programming speed and ease of use since its release in 2012.
* Welding Procedure Specification
From concept to reality. Now on a more powerful platform.
The fastest and easiest way to automate robot programming.
Visual Components is still the fastest way from concept to reality, now with improved performance, deeper customization, and expanded tools for virtual commissioning. Whether you’re building layouts, simulating workflows, or connecting to real systems, Visual Components 5.0 gives you more control and confidence at every step of your digital production planning journey.
Automated Simulations & Checks *
Smarter simulation
Many simulation tools fall short of the real needs of modern production planning. Limited customization, slow performance, and disconnected workflows with multiple tools can slow down decisions and delay projects.
Visual Components 5.0 tackles these challenges head-on. It runs faster, gives you more control over how your simulations work and includes better tools for testing and connecting to real systems, all on a single, unified platform that brings clarity and confidence to every step of your digital production planning journey.

Accelerate design-to-production with precision:
* Available in 5.0 at all OLP products.
Speed up programming with consistent, production-ready paths *
Faster, scalable robot programming
Visual Components OLP 5.0 streamlines automated robot programming with built-in post-processors, extending support to 22 robot brands. It automates robotic welding parameters application and robot path solving to avoid collisions. The new Fronius welding power source connector further simplifies weld job management.
Scale robot programming with speed and consistency:
* Automatic path solver - is available in 5.0 to all OLP customers with active maintenance or subscription. Please see the complete compare list what OLP product to choose.
Automate data exchange with Fronius connector *
Fronius connector - easy, precise weld job management
Connecting welding power sources to robot programming has traditionally required manual data transfer and separate tools, adding complexity and increasing the risk of errors. With Visual Components OLP 5.0, the Fronius connector automates this integration by enabling direct communication with Fronius welding power sources.
Simplify and improve welding workflows:
* Available in 5.0 at all OLP products.
