With extensive experience in weld cost analysis, process validation, and automation readiness assessments, Chris helps manufacturers strengthen upstream fabrication processes before investing in robotics — ensuring automation delivers measurable, long-term value.
Robotic welding is often presented as the solution to labor shortages, rising production costs, and increasing demand. While robotics can absolutely address those challenges, success depends on far more than choosing the right robot. If the parts feeding the cell aren’t consistent, automation simply makes those inconsistencies more obvious.
Over the years, I’ve seen robotic welding projects succeed because manufacturers took the time to prepare their processes first. I’ve also seen projects struggle when that step was skipped. This customer’s experience is a good example of why preparing the process is often more important than selecting the robot itself.
Labor Shortages Started the Conversation
Our discussions with this manufacturer picked back up after they began struggling to hire experienced welders. Like many fabricators, they were finding it increasingly difficult to maintain production with skilled labor becoming harder to find.
To understand whether robotic welding made financial sense, we completed a Weld Cost Analysis (WCA), evaluating factors such as weld length, cycle time, annual production volume, and labor requirements.
The numbers were compelling. Based on the projected throughput, the investment could pay for itself in roughly six months.
From a financial perspective, automation was an easy decision. The bigger question was whether the existing manufacturing process was ready to support it.
Process Validation Revealed the Real Challenge
Before moving forward, we brought several part assemblies into our showroom to validate the application.
During testing, it became clear that the parts weren’t consistent enough for efficient robotic welding. Dimensional variation from one assembly to the next meant the robot would require frequent touch sensing and repeated programming adjustments just to compensate for changing part locations.
The robot itself wasn’t the issue. The variability coming into the cell was.
Rather than installing automation that would constantly be working around inconsistent parts, we recommended improving the upstream processes first.
Strengthening the Foundation
The customer focused on the areas creating the most variation throughout production.
They upgraded their press brake with precision WILA tooling and hydraulic clamping to improve repeatability during bending. They also replaced plasma cutting with a Mazak laser cutting system, significantly improving both edge quality and dimensional consistency.
As those improvements were implemented, fit-up became more predictable and assemblies required far less adjustment before welding.
Although these investments were made with robotic welding in mind, they improved the entire fabrication process along the way.
Returning to Robotics
About a year later, we revisited the robotic welding project.
This time, the results were dramatically different.
One of the customer’s high-volume parts was programmed in approximately 20 minutes, completed in a seven-minute weld cycle, and passed pressure testing on the very first part.
Nothing significant had changed about the robot itself. What had changed was the consistency of the parts entering the welding cell.
The customer moved forward with the purchase and has since expanded to three robotic welding cells, each benefiting from the improvements made upstream.
Why Process Readiness Matters More Than Ever
This experience reflects what many manufacturers are facing today.
Finding skilled welders continues to become more difficult, while customer expectations for quality, traceability, and consistency continue to rise. At the same time, many shops are producing a wider variety of parts in smaller batches, making stable cutting and forming processes even more important.
Robotic welding can help manufacturers address these challenges, but only when the supporting processes are consistent enough to allow the robot to perform efficiently.
A Simple Readiness Checklist
Before investing in robotic welding, it’s worth evaluating a few key areas of your operation:
- Are cut parts dimensionally consistent?
- Are bends repeatable from part to part?
- Do assemblies fit together with minimal adjustment?
- Is production volume sufficient to justify automation?
- Is your team prepared to support and maintain an automated process?
If these fundamentals are in place, robotics can deliver exceptional results. If they aren’t, it’s usually better to address them first.
Final Thoughts
Robotic welding is one of the most effective ways to improve productivity, consistency, and throughput—but like any manufacturing investment, it delivers the best results when it’s built on a stable process. Taking the time to evaluate readiness upfront helps ensure your automation project performs as expected from day one and continues delivering value for years to come.
