Abstract
PURPOSE: To improve the yield of formation by preventing a tack welding defect by welding a butt part on an internal diameter side by leaving a tubular steel plate formed in an "O" shape in a press.
CONSTITUTION: Material 1 formed by O press 2 is not taken out of 0 press 2 but left in the press. Next, either mechanical or manual spot welding is carried out at the longest intervals where a formed product does not cause a spring back, or formed product 1 after entire- length tack welding is taken out of the O press 2.
