Web20 feb. 2015 · Keyhole mode heating achieves its weld penetration in a different way. During keyhole mode welding the power density is great enough that the metal goes beyond just melting. It vaporizes. The vaporizing metal creates expanding gas that pushes outward. This creates a keyhole or tunnel from the surface down to the depths of the weld.
