forge weld

The temperature required to forge weld is typically 50 to 90 percent of the melting temperature.

The metal surfaces reach a temperature at which they flow plastically under pressure, surface impurities are expelled and a forged weld is formed.

The sequence and location of the forge welds varied between different anvil makers and the kind of anvil being made.

Sufficient electrode force is applied to hold the two sheets of metal together and the peak current rapidly creates a forge weld at the interface between the two sheets, producing a small nugget of weld metal, which when cooled results in a shear resistant metal interface.
