ArcNC Welding Agents
Capture welding expertise, automate robot programming, and continuously improve production from design to execution.
ArcNC Welding Agents combine company-specific welding knowledge with deterministic robot planning. They help manufacturers specify welds, generate robot programs, adapt execution on the shop floor, and feed production insights back into engineering.
Welding expertise is scarce
Expert welders and robot programmers are hard to find. In many factories, the knowledge needed to produce high-quality welds is spread across departments, local experts, spreadsheets, drawings, WPS documents, robot programs, and production experience.
This creates three structural problems:
1. Expertise is hard to scale
Critical welding decisions depend on a small number of experienced people.
2. Knowledge stays siloed
Design, welding engineering, production planning, and shop-floor execution often work with different tools and incomplete feedback loops.
3. Manual processes waste time
Weld identification, weld specification, robot programming, sensing setup, and program validation still require too much repetitive manual work.
ArcNC turns this fragmented expertise into a shared, operational welding system.
ArcNC Welding Agent
A company-specific welding expert, from design to execution
The ArcNC Welding Agent is a vertically integrated welding assistant that supports the full product development workflow, from Design, Specification and Planning to Execution.
It combines historic parts and previous production decisions, company welding policies, WPS and process knowledge; with deterministic robot motion planning, and runtime, scan, and inspection feedback.
The result is a company-specific agent, embedded in the existing engineering and production workflow.
Grounded in deterministic execution planning
The Welding Agent is built on ArcNC Core: an automation platform for weld specification and robot programming.
1. Weld seam extraction
ArcNC extracts weld seams directly from CAD data or imports existing weld files. This removes the need to manually draw weld lines and creates structured weld geometry that can also be exported for structural analysis.
2. Motion planning
ArcNC generates robot motions while accounting for collisions, singularities, joint limits, cable management, torch positioning, and positioner angles, including harmonic motion where needed.
3. Online adaptation
ArcNC uses different online measurement methods to detect and correct deviations between the virtual model and the physical part, allowing accurate welds even when the physical part differs from the CAD model.
Design for manufacturing
The Welding Agent supports engineering teams before production starts.
It can help validate layouts, generate manufacturable alternatives, support fixture decisions, and guide designers toward parts that are easier to weld robotically.
Example capabilities:
- layout validation and generation
- design copilot for welding manufacturability
- part fixturing support
- early feedback before drawings are released
Automatic weld specification
The Welding Agent helps translate geometry, policies, and previous decisions into welding specifications.
It can use WPS knowledge, embed company policies, and extrapolate from similar parts to propose weld specifications more consistently.
Example capabilities:
- automatic weld specification
- WPS-based decision support
- company policy enforcement
- reuse of knowledge from similar parts
Deterministic robot programs
Once welds are specified, ArcNC generates deterministic robot programs.
The agent can support the planning process, but the actual robot paths are generated through ArcNC’s deterministic planning engine. This keeps the system reliable and suitable for industrial production.
Example capabilities:
- torch positioning
- robot motion planning
- positioner optimization
- collision-aware paths
- post-processor output for robot execution
Intelligent execution on the robot
The Welding Agent extends beyond offline programming. It connects planning with execution and feedback.
On the shop floor, the system can support scanning, execution, monitoring, adaptation, and replanning when necessary. Runtime and inspection data can then be fed back into the agent to improve future decisions.
Example capabilities:
- scan scene, part, and welds
- execute and monitor robot programs
- adapt to deviations
- replan where required
- feed back runtime and inspection data
Why it matters
ArcNC Welding Agents help manufacturers move from manual, expert-dependent workflows to scalable welding automation.
For design teams
Earlier manufacturability feedback and fewer late-stage production issues.
For welding engineers
Faster weld specification and better reuse of previous expertise.
For robot programmers
Automated program generation with deterministic planning and fine-tuning where needed.
For production teams
More robust execution, sensing, adaptation, and inspection feedback.
For the organization
A shared welding knowledge layer that captures expertise instead of losing it in silos.
