What is Welding?
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
Welding is the process of joining metals by melting the parts and then using a filler to form a joint. Welding can be done using different energy sources, from a gas flame or electric arc to a laser or ultrasound. Until the beginnings of the 20th century, welding was done via a process known as forge welding, which consists of heating up the pieces to be fixed together and then hammering them until they amalgamate. With the advent of electricity, welding became easier and faster, and it played an important part of the industry scene during World War I and II. There are different welding processes in use in modern times: • Arc welding is done through the use of an electrical current, and can be performed by using inexpensive equipment. • Gas Welding is widely used for repair work, especially in anything involving pipes and tubes. Gas welding is common in the jewelry industry, as well as for the welding of plastics and other materials that cannot stand higher temperatures. • Resistance w

Welding is the process of joining metals. A combination of heat and fuel gas literally melts the materials. When they cool, the materials are permanently fused as one. General uses for welders include assembly and repair of ductwork, gutters, gates and grills, as well as lawn, garden and farm equipment repair.
