About this course

This course guides you through learning shielded metal arc welding (MMA), an accessible and versatile technique. You will learn the theoretical and practical basics, from material preparation to choosing the right electrodes and settings. Through practical modules and targeted exercises, you will be able to identify and correct common welding defects. An AI-powered image analysis system will help you identify imperfections in your welds by examining the photos you submit. This course provides basic technical training and does not replace mandatory courses, official certifications, or the advice of a qualified professional.
