16 Facts About Forge welding
1.
2.
Forge welding is versatile, being able to join a host of similar and dissimilar metals.

3.
Forge welding is a process of joining metals by heating them beyond a certain threshold and forcing them together with enough pressure to cause deformation of the weld surfaces, creating a metallic bond between the atoms of the metals.
