Robotic Welding Systems - Midwest Engineered Systems

Custom Robotic Welding Solutions

Whether your parts are simple, have complex geometries, or require heavy welding applications, MWES offers custom, turnkey, and automated welding systems for a variety of capability ranges and weld processes. Our experience and in-house capabilities allow us to design, build and install custom robotic welding systems. We also have a number of AWS Certified Welding Inspectors and Certified Robotic Arc Welding Technicians on staff to ensure high-quality results for your automation system.

Robotic welding systems can offer many distinctive benefits to organizations large or small. Advancements in the field of robotics have made automation of even a few processes, a productive and cost-saving innovation that companies of any size can benefit from.

From improved productivity and adaptability to fewer weld distortions, here are seven advantages that businesses see when they invest in and implement robotic welding systems:

More Productivity

Robots are generally more efficient at welding tasks than humans are. With a robotic welding system, welded components can be processed between three to five times more efficiently than using manual welders. Robots can work continuously, with no need for breaks. They also have higher arc on-time percentages than professional welders.

To consistently replicate results, a manual welder has to gain a high skill level and maintain high concentration levels on each and every task. A robotic welder is capable of processing the same welding tasks with repeatable results continuously, for as long as is necessary.


Manual welders make use of several jigs, using different ones with different production runs. Robots reduce time spent changing tools with their grippers that can handle parts of any size or shape. These robotic grippers can grab a welding component, place it properly on the assembly and keep a firm hold on the part while performing welding processes on it.

Limiting Weld Distortions

Contractions and expansions of the base and weld metal during the heating and cooling phases of a welding process, lead to distortions. MWES designs robotic welders to be fine-tuned to properly size the weld based on the joint requirements. This reduces the number of necessary weld passes, allowing the robotic welder to complete the weld very efficiently and reduce the time that the metals are exposed to heat, thus reducing the chance of distortions.

Labor Solutions

When there is a lack of skilled manual welders, robotic welders can handle the workload, as well as reduce the number of additional hours a business needs for production purposes, since they alleviate the need to seek and train more welders.

Reduction In Sizing Errors

Manual welders determine the size of the weld based on the operator’s judgment. This could lead to larger welds than what was actually needed. Robot welders are programmed to select the correct dimensions of the joint required for the job, saving time and materials for each welding task.

Lower Production Costs

Robots offer a variety of production cost-saving benefits. Robotic welders can fully produce parts at lower production costs by increasing overall productivity, quality and consistency across the entire welding process. Robots require less energy than manual welders and have fewer requirements for consumables, due to their improved efficiency with materials and with welding cycles.
