Weld It is the STEM song played in Knights in Sparkling Armor. It is performed by Felicia Barton, and plays after Blaze, AJ, and Sparkle escape the bouncing cannon blasters while on their way to save Crusher and Pickle from the bubbling slime swamp.
Keep metal pieces really hot
And get those particles moving fast
Melt them together, what do we got?
A new piece that's built to last
Building bridges, planes and cars
Welding pipes, and work supplies
Weld it, weld it
Metal pieces melting together
Weld it, weld it
Metal pieces melting together
Weld it, weld it
Weld it, weld it
