Free online courseLearn How to MIG Weld

Course Description

MIG welding is one of the most practical shop skills you can add to your toolbox, whether you want to tackle automotive repairs, metal fabrication projects, or improve your professional options in the trades. This free online course guides you through the fundamentals of MIG welding with a clear, hands-on approach, focusing on the decisions that make the difference between frustrating welds and clean, reliable results.

You will learn how to set yourself up for success from the start by understanding how a MIG welder works, how shielding gas supports weld quality, and how the right setup helps prevent common problems like burn-through, spatter, and weak joints. Instead of guessing, you will build confidence in dialing in your machine by recognizing the roles of arc voltage and wire speed and how small adjustments change arc behavior, bead appearance, and penetration.

Because many beginners struggle most with thin material, this course emphasizes techniques that help protect sheet metal from excessive heat and warping. You will also see why preparation matters, how proper panel conditioning can improve consistency, and how the right prep process supports better fit-up and stronger welds. Along the way, targeted questions reinforce key concepts such as recommended wire size for automotive sheet metal, common shielding gas mixes for ferrous metal, and practical methods to manage heat input.

By the end, you will have a stronger foundation to weld more safely, make cleaner tacks and seams, and approach future projects with a process you can repeat. If you are looking for an accessible starting point that builds real-world MIG welding confidence, this course is a straightforward way to level up and start practicing with purpose.
