developments in automatic welding, alternating current, and fluxes fed a
major expansion of arc welding during the 1930s and then during World War
II.
A significant invention was defined in a patent by Alexander, filed in
December 1924, and became known as the Atomic Hydrogen Welding
Process. It looks like MIG welding but hydrogen is used as the shielding gas
which also provides extra heat. A major innovation was described in a patent
that defines the Submerged Arc Process by Jones, Kennedy and Rothermund.
This patent was filed in October 1935 and assigned to Union Carbide
Corporation.
Russell Meredith working at Northrop Aircraft Company in 1939-1941
invented the TIG process. This new process was called "Heliarc" as it used an
electric arc to melt the base material and helium to shield the molten puddle.
Mr.Jack Northrop's dream was to build a magnesium airframe for a lighter,
faster warplanes and his welding group invented the process and developed
the first TIG torches. The patents were sold to Linde who developed a
number of torches for different applications. They also developed procedures
for using Argon which was more available and less expensive than Helium.
In 1957, the flux-cored arc welding process debuted, in which the self-
shielded wire electrode could be used with automatic equipment, resulting in
greatly increased welding speeds, and that same year, plasma arc welding
was invented. Electroslag welding was released in 1958, and it was followed
by its cousin, electrogas welding, in 1961.
Other recent developments in welding include the 1958 breakthrough
of electron beam welding, making deep and narrow welding possible through
the concentrated heat source. Following the invention of the laser in 1960,
laser beam welding debuted several decades later, and has proved to be
especially useful in high-speed, automated welding. Both of these processes,
however, continue to be quite expensive due the high cost of the necessary
equipment, and this has limited their applications.
