What is welding and what do welders do?
Welding is the most economical and efficient way to join metals
permanently. It is the only way of joining two or more pieces of metal to
make them act as a single piece. Welding is vital to our economy. It is often
said that over 50 % of the gross national product of the U.S.A. is related to
welding in one way or another. Welding ranks high
among industrial processes and involves more sciences
and variables than those involved in any other industrial
process. There are many ways to make a weld and many
different kinds of welds. Some processes cause sparks
and others do not even require extra heat. Welding can
be done anywhere… outdoors or indoors, underwater and in outer space.
Nearly everything we use in our daily life is welded or made by
equipment that is welded. Welders help build metal products from coffeepots
to skyscrapers. They help build space vehicles and millions of other products
ranging from oil drilling rigs to automobiles. In construction, welders are
virtually rebuilding the world, extending subways, building bridges, and
helping to improve the environment by building pollution control devices.
