WELDMENTS INC HISTORY
Founded in 1964 by John M. Gleasman & Partner, James E. Johnson, Weldments Inc. quickly made a name for itself in the Machine Tool and Heavy Industrial Fabrication market. Soon, it outgrew the original location below the Rock River Dam in Rockford, IL.

In 1967, Weldments Inc. built and moved into its current 22,000 sq ft location in Machesney Park, IL.
John's son, Steve Gleasman, started working at Weldments Inc. in 1983, eventually taking over as president in 1993 following his father's retirement. Over the next 30 years, Steve and his long-time friend and General Manager, Dan Riley, grew Weldments Inc. into what we are today. Although recently retired in July of 2024, Steve remains active in the success of Weldments.
