This section covers advanced knowledge essential to certified welders, including identifying weld types, proper heat control, electrode selection, and understanding welding codes and standards. It emphasizes the importance of following correct procedures for fillet, groove, and spot welds, and differentiates between destructive and nondestructive testing methods used to evaluate weld integrity. Learners review the purpose of organizations such as the EPA and AWS, and the importance of safety measures, including proper ventilation, grounding, and color-coded hazard identification. The unit highlights essential machine settings — including duty cycles, amperage, polarity, and voltage control — and their effect on weld quality and defects such as undercutting, concavity, and porosity. Students also explore gas types, shielding compositions, and proper storage of cylinders for safety. Overall, this unit prepares welders for industry-recognized testing and certification by reinforcing the theoretical and practical foundations of welding.
