ABSTRACT:
A method and apparatus for manufacturing metal profile members, hollow bodies and the like wherein a plurality of continuous band-like metal strips of constant wall thickness as viewed in cross-section are continuously fed along separate paths which converge. The band-like metal strips are heated at predetermined selected areas to a welding temperature and then continuously press-welded together to form the profile members. One or more of the band-like metal strips may be deformed by cold-shaping prior to the press-welding operation. Hot-shaping may occur simultaneously with or immediately after the press-welding operation. Also, cold-shaping of the welded material may take place following the press-welding and hot-shaping steps to form a metal profile member of predetermined configuration.
