Stop Teaching Robots to Weld and Start Welding

Most AI-enabled robots learn how to weld. XpertLINC™ already knows how. We have spent more than 100 years mastering the weld. We built that experience into XpertLINC and launched it on a Cooper® cobot. It looks at the real joint in front of it, not a perfect drawing. Then it builds the weld plan and commands the robot and the arc together, inside your approved WPS.

What if programming didn’t stand between you and the weld?

The XpertLINC platform adapts to real-world conditions without going outside your approved weld procedure. Each weld goes through the following process:

Vision Scanning Icon

Scan

Capture the actual joint and fit-up condition.
Data Gear Icon

Understand

Apply welding science and mathematics to interpret the joint.
Clipboard Checkmark Icon

Plan

Generate coordinated motion and weld parameters inside the process window.
Robotic Welding Icon

Command

Control robot motion and welding arc together.

The XpertLINC Advantage

Many AI-driven solutions rely primarily on learned behavior. They collect data, train a model and use previous outcomes to determine how the system should respond. When a new part, joint condition, or source of variability is introduced, additional iterations may be required before the system reaches a production-ready result.

XpertLINC takes a fundamentally different approach. It combines Lincoln Electric welding expertise, factual weld data, physics-based mathematics, and engineering principles. The system does not simply recognize what worked before. It applies the welding science behind why a response is appropriate.

That foundation allows XpertLINC to evaluate the joint that is actually presented, develop coordinated robot motion and weld parameters, and execute the weld inside the working ranges established for the customer-authorized WPS.

Most Started with the Robot. We Started with the Weld.

XpertLINC commands the motion and the arc as one and checks every joint against your approved procedure before the first spark.

Frequently Asked Questions

With any new technology, questions are expected! That's why we anticipated your FAQs with answers from the experts below.

What is the XpertLINC platform?

XpertLINC is Lincoln Electric’s next-generation industrial automation platform that integrates Physical AI-assisted decision tools to optimize manufacturing performance. It brings together welding expertise, automation controls, and intelligent software into a unified environment designed to:
• Improve quality and repeatability
• Increase throughput and reduce rework
• Provide adaptive insights to operators and engineers
• Enable faster programming, troubleshooting, and optimization
Unlike generic AI tools, XpertLINC is purpose-built for physical manufacturing environments, with safety, reliability, and data segregation built into its architecture.

What makes XpertLINC different from other automation or AI-enabled welding solutions?

XpertLINC is different because it automates welding intelligence, not just robot motion.

Unlike traditional “no-programming” or AI solutions that still rely on CAD models, static assumptions, or offline teaching, XpertLINC fuses motion, process, and sensing to adapt in real time. It uses live sensor data and Physical AI to generate optimized weld paths and parameters directly from the real world without requiring CAD models or programming expertise.

XpertLINC’s advantage is amplified by Lincoln Electric’s uniquely differentiated position in the automation stack. Lincoln Electric is uniquely positioned to combine welding power source technology, consumable development, welding procedure expertise, automation systems integration, advanced sensing technologies, and application engineering knowledge within a single integrated platform.

This enables XpertLINC to make welding decisions based on real welding science, process expertise, and proven fabrication knowledge rather than generalized automation assumptions.

The result is faster deployment, consistent quality despite part variation, and expertlevel
welding performance without expert-level labor.

What problems does XpertLINC solve for manufacturers?

XpertLINC directly addresses the biggest barriers to automation adoption:
• Skill shortages: XpertLINC determines weld paths, parameters, and corrective actions, reducing reliance on skilled programmers or   welders.
• Part variation: Real-time sensing allows XpertLINC to adapt to joint variation, misalignment, or inconsistent fit-up.
• Throughput and quality challenges: XpertLINC improves repeatability and reduces rework by enforcing Weld Procedure Specification,            or WPS, limits and adjusting in real time.
• Scalability: One operator can oversee multiple cells.

What industries benefit most from XpertLINC?

XpertLINC is ideal for any operation facing high variation, high-mix production, or difficulty finding skilled welders. Common applications include:
• Fabrication requiring multi-pass welds
• Large assemblies where part placement varies
• Shops struggling to produce repeatable parts
• Environments with high turnover or training burden

Do I need CAD models to use XpertLINC?

No. XpertLINC eliminates the need for CAD-based programming entirely. Other automation systems depend on digital models that rarely match real-world parts. XpertLINC uses sensor scans and Physical AI to generate correct weld paths and parameters automatically, directly from actual geometry.

 

What are weld procedure specifications, and why should I care about them?

In short, a Weld Procedure Specification (WPS) is the foundation of consistent, compliant welding.

A WPS is a formal document that defines how a weld must be made to achieve the required strength, quality, and compliance. A WPS specifies the essential variables of welding, such as process type, filler material, voltage, current, travel speed, joint design, and acceptable tolerances based on proven procedures.

• Ensures weld quality and mechanical performance
• Maintains repeatability across operators, shifts, and locations
• Reduces defects, rework, and scrap
• Supports code and regulatory compliance, such as AWS, ASME, and ISO
• Protects your organization during audits or inspections

Can XpertLINC handle multi-pass welding automatically?

Yes. XpertLINC automatically:

• Generates stacking patterns
• Analyzes each pass
• Rescans between layers, if needed, to adapt to height changes
• Optimizes fill strategies using Physical AI models

How does XpertLINC improve adaptability on the shop floor?

XpertLINC adapts as the weld evolves. Using layer-by-layer scanning, the system recalibrates the weld plan after the initial scan to ensure each layer meets the specification. This allows XpertLINC to handle natural variations and inconsistent fit-up that defeat conventional automation.

Which welding processes are supported by XpertLINC?

XpertLINC supports a wide range of welding applications, including:
• Steel
• Stainless
• Cored

Is XpertLINC repeatable enough for high-mix production?

Yes. XpertLINC easily generates new programs when a new job comes on the line.
