Question

In solid-state welding, the contamination layers between the surfaces to be welded are removed by

Correct answer (B) plastic deformation Solution In solid-state welding processes (like friction welding or diffusion welding), the surfaces are brought into intimate contact. Surface oxides and contamination layers are broken up and dispersed by the plastic deformation occurring at the interface, which allows for atomic bonding between the two surfaces. Turn this into a strength. Explore AI-powered practice and doubt support with Success Tracker.
