The present invention relates to a method for butt joint of rolling pieces comprising: cutting a head part of a first rolling piece which is in a feeding direction to form a first inclined butt joint edge in a preset sharp angle &thetas; against a working roll generatrix of a working roll, wherein a value of the angle makes the width of the first inclined butt joint edge along a vertical direction of the working roll generatrix greater than the width of a distortion area where the working roll touches the rolling pieces; cutting a tail part of a second rolling piece which is in the feeding direction to form a second butt joint edge parallel to the first inclined butt joint edge; setting the first inclined butt joint edge and the second inclined butt joint edge relatively clingy; and welding relatively clingy parts to connect the first rolling piece with the second rolling piece. The present invention greatly ensures the intensity of the rolling pieces, prevents the rolling piece from being ruptured and ensures the stability of the rolling speed of the whole continuous rolling system and the quality of the rolling pieces.
