Robotic Welding Is the Key to Success for Ladder Manufacturer

Lincoln Electric and Cotterman partner to create a flexible robotic welding solution to address a high-mix production facility

Cotterman Co., a manufacturer of steel rolling ladders, and the recipient of the 2011 W.W. Grainger, Inc. Partners in Performance Supplier of the Year Award, devotes a part of its success to its ongoing collaboration with the Lincoln Electric Automation Division.

In 2011, Croswell, Mich.-based Cotterman was able to enhance operator efficiencies and productivity, reduce manufacturing turnaround time, lower inventory costs and maintain product quality by incorporating Lincoln Electric's Robotic Welding System 55 in its manufacturing facility.

The System 55 is a pre-engineered dual headstock robotic welding cell, designed for large sized parts that can be welded using the flexibility of reorientation. Using customization on both sides of the cell layout, Cotterman welders were able to weld the entire rolling stair tread on Side A and weld common parts, fixtures and components on Side B. With the new addition of the System 55 from Lincoln Electric Automation, Cotterman reduced its finished inventory to zero, created a just-in-time manufacturing process and improved order fulfillment to 48 hours or less.

"The service from Lincoln is the best in the business," says Cotterman Vice President Nick Valore. "Teaming with Lincoln is a no brainer."

A case study detailing the collaborative project and a supplemental video complete with interviews from Valore, as well as Cotterman's president, Clint Stimpson, are available. These can be found on and
