About this course

This course is designed for DIY and metalworking enthusiasts who want to learn the basics of MIG/MAG welding. Through modules covering settings, wire and gas selection, and different welding positions, you will gain practical skills for making solid joints. The course includes guided exercises to immediately apply what you've learned. An artificial intelligence system will help you assess the quality of your weld beads, providing instant visual feedback. Remember that this course provides technical training and does not replace mandatory courses, official certifications, or the advice of a qualified professional.
