A process for pressure welding two metal bars together by their ends which comprises bringing together the ends to be welded, the ends being in a wedge-shaped form and at a temperature between melting temperature and 450 DEG C. below the melting temperature, pressing both ends together in the longitudinal direction of the bars so that the ends penetrate into each other, with the edges of the wedges in crossing relationship, and continuing to press both ends into each other until substantially all of the surface material of both wedges is expelled out of the cross-sectional shape of the welded bars. |
