Welding Levels 1 - 3: You will be trained on how to carryout the fabrication process which involve joining materials together, usually metals or thermoplastics, by using high heat to melt the parts together and allowing them to cool, causing fusion. Welding is distinct from lower temperature metal-joining techniques such as brazing and soldering, which do not melt the base metal. At the end of the program you will be equip with the skills needed to perform all welding tasks.
