St. Louis, MO — Stoody celebrates its 90th anniversary in 2011. In 1921, brothers Winston and Shelley Stoody opened up the Stoody Welding Co. in Whittier, CA, to service the growing farm implement and tractor repair business. When oil was discovered nearby, the Stoody brothers began repairing drill bits from the oil rigs. To make drill bits more durable, they developed a technique called hardfacing that is still used today. Stoody joined the Thermadyne Industries family in 1988.
