Use of arc for illumination. By 1809 he had demonstrated
that it was possible to maintain high voltage

In the nineteenth century, practical power-generating
devices were invented and developed on a practical basis.
These inventions were the forerunners of the current arc.

The first documented example of fusion welding was
Introduced in 1881 by Auguste de Meritens. they welded

After four years of work, he was released
Application of The process involved fusion welding of
metals, cutting metals, and punching holes in the metal. Although he

Popular because of the high rate of metal deposition
and
Absence of arc blow.
World War II spurred the development of inert gas
A patent was issued in
Hobart and Devers since 1930 for the use of electric arc
in an inert gas environment. process was not good
Due to the high cost of argon received by the industry
and
Lack of helium and suitable torch equipment.
The following procedures include the use of: Electric arc:
• Arc Spot Welding
• Atomic-Hydrogen Welding
• Electrogas
• Plasma arc welding
• metal joining
• submerged arc welding
• Underwater arc welding
Other specific procedures include:
• Cold Welding
• Electron Beam Welding
• Explosive Welding
• Forge Welding
• Friction Welding
• friction stir welding
• Laser Welding
• Oxyhydrogen Welding
• Thermit Welding
• ultrasonic welding
• Welding of Plastics
There are over 90 welding processes in use today.
Industry demands in the future will force new and
improved developments in machines, gases, torches, electrodes, processes and
technology. ship building,
do continuous research for space, and the nuclear
industry
New metals, which in turn promote research in welding.
At present, five welding unions provide guidance
and standards related to the welding industry.
• American National Standards Institute (ANSI)
• American Petroleum Institute (API)
• American Society of Mechanical Engineers (ASME)
• American Welding Society (AWS)
• US Bureau of Shipping (ABS)
Industrial Welding Applications
Welding is not a simple operation. Over 90 different
welding processes in three major . is divided into
Types: arc, gas and resistance welding. number of others
Types like induction, forge, thermit, flow welding, and
Brazing is used somewhat less
The following welding occupations require high School Education:
• Welding Operator

safety and working condition
Welders perform a wide variety of tasks in almost any
environment. They can do light or heavy welding, indoors or
Outside, in spacious surroundings or cramped quarters.
Often they work in strange conditions in boiler shops,
Shipyards, tanks and piping systems. the work may be very
noisy (hearing protection will be required), and
Welders may have to work on scaffolds higher than the
ground
(requires use of a safety harness)
