Description
The linear friction welding of carbon steel using low frequency and low amplitude so as to weld below the A1 transformation temperature and so avoid martensitic transformation was investigated. The end faces of JIS-S45C carbon steel (0.48%C, 0.77%Mn) specimens, 65 x 25 x 5 mm, were subjected to linear friction welding using welding parameters of: frequency 15 Hz; amplitude 1 mm; forging force 50-200 MPa. Temperatures were measured during welding, and the welded joints were evaluated by microstructural studies, and determinations of phase composition and microhardness. The results were compared with those of welds produced using conventional parameters: frequency 50 Hz; amplitude 2 mm. Welding parameters were identified which produced defect-free welds below the A1 transformation temperature.
