WELF 101 - Welder Foundation

Welders are people who have training in and are capable of welding ferrous and non-ferrous metals in all positions, on plate and/or pipe, using SMAW, GTAW, and FCAW processes. Welders use manual or semi-automatic welding equipment, flame-cutting, brazing and air-arcing equipment. Additionally, they use machines such as brakes, shears and other metal straightening and bending machines. Welders generally plan work from drawings or by analyzing the job tasks, and determine the materials and welding processes required to complete the job. They may specialize in certain types of welding such as custom fabrication, shipbuilding and repair, pressure vessel welding, pipeline construction welding, structural construction welding or machinery and equipment repair welding. Welders use blueprint symbols to determine machining operations. They check product specifications using precision measuring instruments and maintain equipment and replace parts when required. Welders use a logbook to record training, competencies, certifications, endorsements and employment history.
