Abstract: The invention relates to a process for guiding sheets or strips to be butt-welded together and to an apparatus with means for conveying and guiding sheets or strips to be butt-welded together. The sheets or strips, lying laterally next to one another, each with one of its side edges against a guide surface lying in the same vertical plane, are brought into contact without gaps in the same horizontal plane, on conveying planes inclined at an acute angle relative to one another. In the apparatus, the conveying means, especially roller tables, form conveying planes arranged at an acute angle  alpha relative to one another. The guide means consist of guide surfaces lying in the same vertical plane. Thus, strips or sheets can be guided continuously past a fixed welding device in order to be welded together without gaps.
