Fusion welding is one of the most important welding processes used in construction and fabrication. In this video, you’ll learn the basics of fusion welding, where metals are joined by melting them using heat sources like arc welding, gas welding, TIG, MIG, and laser welding. You’ll also see how filler metal is added, how the molten weld pool forms, and why fusion welding creates strong and permanent joints. This process is widely used in pipelines, steel structures, workshops, and heavy industr

A weld that looks good can still be unsafe. Austin’s weld looked fine but the polarity was mixed up giving him zero fusion. This is why processes like X Ray, dye penetrant, and mag particle inspection are used on critical welds. Watch the full breakdown on YouTube https://youtu.be/sC2RjZDeFfU | Weld.com
