摘要： A method of rolling a continuous welded billet having weld joints at successive locations along the billet and wherein the continuous welded billet is advanced through roll pairs of successive roll stands. The rolling conditions in two successive stands are adjusted so that when a weld joint is between the two stands compression is produced at the weld joint causing an increase of cross-sectional area at the weld joint. The rolling condition involves superimposing an increase in roll speed in the upstream roll stand compared to the downstream roll stand based on tracking information of the weld joint.
