  • The Tuffaloy story begins in 1937, when Walter H. Simmons of the Welding Sales & Engineering of Detroit introduced a new line of resistance welding alloys tradenamed TUFFALOY. What began as a general line of resistance welding alloys, soon grew to a complete standardized product line of resistance welding consumables to support the growing manufacturing industry in the United States.
  • In 1963, Walter P. Simmons created Tuffaloy Products, Inc. as a standalone entity solely focused on suppling resistance welding consumables. The shift in focus allowed Tuffaloy to expand their standardized product offering and develop innovative products such as multi-electrode holders which improve efficiency and weld quality.
