NEWS 17 PRESIDENT’S HALL OF FAME: # 3 by AWD President Bob Stacey
I hope you all enjoyed the last of our hero’s Hall of Fame. This time, before we travel too far forward, I have listed a number of lesser known heroes. Some you may not know but there is no doubt their contribution, to our world of welding, has been significant.
SOME IMPORTANT EVENTS IN OUR WELDING HISTORY.
1774Joseph Priestly heated mercuric oxide and produced dephlogisticated air, now commonly known as Oxygen.
1820Andre Marie Ampere was pioneering the field of electro magnetism; the unit of Ampere is derived from his name.
1827George Simon Ohm discovered the resistance in an electrical circuit. The term Ohm is derived from his name.
1831Michael Faraday obtained electricity from magnets, the later experiments resulted in the invention of the dynamo.
1847Robert Hare is credited with the invention of the oxyhydrogen blowpipe.
1800Italian Alessandro Volta discovered that two dissimilar metals connected by a substance that became a conductor, when moistened, would form a voltaic cell. A voltaic cell is composed of two chemicals with different electron attracting capabilities, of which are immersed in a electrolyte, and connected to each other via an external circuit. The term Volts is derived from his name.
1801 The discovery that an electric arc could be maintained between two terminals belongs to Humphry Davy. With this single invention this is the beginning of the modern joining of metals.
1887Thomas Fletcher developed a blowpipe that could use either hydrogen or coal gas to use with oxygen to cut thick section steel.
1881A Demeritens joined lead plates in batteries.
1885Nokolai N Bernardos and Stanislaus Olczewski used carbon arc process to arc weld metals.
1888Bernados is granted a patent for carbon arc welding process.
1892C L Coffin developed an apparatus enclosed in a container filled with inert gas. This became the forerunner for the inert gas welding process.
I hope you have found this trip back to our welding history interesting; we could have spent some time investigating each hero in some depth, as they all have played a major part in our industry. In our next time travel, we will be moving forward in time, and I will include our welding heroes who helped shape and develop the welding processes we use today. We will Travel again in the next Edition, for more Hall of Fame Heroes.

1892 Thomas Willson who for ever will be known as Thomas Carbide. Willson discovered by accident an inexpensive way of manufacturing Acetylene gas.
1900 Hans Goldschmidt invented the thermit welding process which was originally called Aluminothermic,or the Goldschmidt process.
