The founder of DNFM, Dr. David N. French, is a pioneer in the industry. He served on several industry-related committees (ASME, EPRI, etc.), and wrote 2 editions of the comprehensive book "Metallurgical Failures in Fossil Fired Boilers" published by John Wiley & Sons Inc.
Resistance welding, invented in 1877 by Elihu Thomson, was accepted long before arc welding for spot and seam joining of sheet. Butt welding for chain making and joining bars and rods was developed during the 1920s. In the 1940s the tungsten-inert gas process, using a nonconsumable tungsten electrode to perform fusion welds, was introduced. In 1948 a new gas-shielded process utilized a wire electrode
