is the most common way of permanently joining metal
parts. In this process, heat is applied to metal pieces,
melting and fusing them to form a permanent bond.
Because of its strength, welding is used in
shipbuilding, automobile manufacturing and repair,
aerospace applications, and thousands of other
manufacturing activities. Welding also is used to join
steel beams in the construction of buildings, bridges,
and other structures and to join pipes in pipelines,
powerplants, and refineries.
The purpose of this welding course is to provide
