Welding is the process of joining together two pieces of metal so that bonding takes place at their original boundary surfaces. Welding is used in the construction and repair of many thousands of manufactured products. The Welding Technology (WDT) Program at Wallace Community College Selma provides students with the technical skills necessary to enter the construction, manufacturing, and repair industries. WDT students attain hands-on experience in a variety of welding processes used by various industries in the fabrication and repair of steel components. Through practical exercises which are designed to be as realistic as possible and representative of actual world-of-work experiences, WDT students learn to use many different cutting and joining processes. The program offers both the basic standard Certificate in Structural Welding as well as a more specialized Standard Certificate in Pipe Welding which permits a student to apply for more competitive pipe welding positions found in heavy industries such as refineries and off-shore drilling rigs.
