This course provides foundational instruction in Tungsten Inert Gas (TIG/Gas Tungsten Arc Welding – GTAW) welding processes used in manufacturing, maintenance, and fabrication industries. Emphasis is placed on safe work practices, proper equipment setup, and the development of fundamental TIG welding skills.
Students will study GTAW theory including electrical principles, shielding gases, tungsten electrode selection and preparation, filler metal selection, and joint design. Laboratory instruction focuses on torch control, arc length, puddle control, and filler metal manipulation through supervised hands-on welding exercises.
Students will practice welding on common base materials such as carbon steel, stainless steel, and aluminum, as equipment and time permit. Instruction includes welding in flat and horizontal positions with an introduction to visual weld inspection and identification of common weld discontinuities.
Upon successful completion of the course, students will be able to safely set up GTAW equipment, select appropriate consumables, and produce visually acceptable TIG welds suitable for entry-level employment or continued welding coursework.
