ABSTRACT:
While the leading end of a first heated workpiece is processed in a rolling mill, the trailing end is joined to the leading end of a second heated workpiece. End portions of the workpieces at the gap therebetween are held by clamp members at a spaced-apart location so that both workpieces advance at the same speed toward the rolling mill. The end portions of the workpieces are cleaned to remove scale and then a mold is positioned to span the gap and contact the end parts of the workpieces. Liquid-weld metal is introduced into the mold and allowed to at least partially solidify before the mold is removed while the rolling operation continues. The weld metal substantially solidifies and is passed through the rolling mill.
