Arc Welding - Midwest Engineered Systems

To remain competitive, more and more industries are turning to automation to fill their production welding needs.  Properly designed and executed robotic welding systems can be over three times more efficient than traditional manual welding, while providing more dependable quality and throughput.

This is where Midwest Engineered Systems’ vast experience designing and implementing automated arc welding systems comes in. MWES provides a wide range of robotic arc welding capabilities and is highly knowledgeable at determining what’s needed to achieve our customer’s goals, regardless of the industry or welding operations needed.

How Arc Welding Works

Arc welding is the most common form of fusion welding used today. Arc welding uses an electric arc to create intense heat at upwards of 6500°F. At those temperatures, metals such as steel, stainless steel and aluminum can soften enough to be joined together. The electrical arc that creates such intense heat can be generated from either an AC or DC power source. When heated at high temperatures, metal will react chemically to oxygen and nitrogen which will liquify at the point of contact.  Once the metal has cooled and solidified, it will form a strong metallurgical bond between the two points of contact.

Traditionally, all arc welding work had been done with manual labor, however, over the last several decades more and more arc welding work has been transitioned over to robotic automation.  Robotic arc welders provide a more consistent throughput and higher quality welds than with traditional manual arc welding, with minimal downtime.  For those reasons, robotic automation in the field of welding is rapidly growing every day.

Today, robotic arc welding is used globally in a number of key industries including the automotive industry, fabrication and in the assembly of large-scale components.  Some of the industrial uses are: steel frame welding, constructing metal enclosures and large machinery, and working in heavy gauge metals.

Midwest Engineered Systems builds custom, turnkey, automated, robotic arc welding systems for a variety of capability ranges depending on your metal fabrication needs.  With an ever-increasing shortage of skilled welders, our automated arc welding systems will provide consistent cycle times, faster production times and an incredible ROI when compared to manual welding.
