Abstract

1,239,142. Jointing by forging; spinning; making pick tips. R. A. BLACK, and E. H. HANDS. 18 March, 1970 [17 March, 1969], No. 13916/69. Headings B3A, B3H and B3J. An insert 3 is mechanically fixed into the recessed end of a shank 2 by a rotating tool 1 for frictionally heating the shank and deforming it around the insert by relative axial movement. The axial pressure may be applied during or after the rotational heating. The insert is preferably a tungsten carbide tip for a coal cutting pick. The tool may be mounted on a friction welding machine for the rotation.
