ABSTRACT:
A butt welding and burr shearing machine for metal rod, e.g., reinforce steel has opposed relatively slidable clamping devices (8, 9), which has positioning clamp (10) and pivotable clamp lever to clamp the rod by lever action. One of the clamping devices mounts split type shear dies by the positioning clamp and the clamp lever respectively. In the cutting position of the shear dies 21, 22 the rod F2 is not clamped by the clamping device 10 on which the shear dies are mounted.
By a series of simple operations the rods to be jointed are loaded sideways, clamped by rotating clamp lever, and pressure butt welded, and bulge formed by welding process is sheared off. The completed rod is removed sideways.
