Abstract

PURPOSE: To shorten the working process, and to reduce the working man-hours, by excluding the butting part, by bending the single sheet so as to form the corner, and by applying the spot welding to the part to be welded.
CONSTITUTION: On the flat sheet 3, the bending line 4 and the bending line 5 are marked parallelly making an offset equivalent to the thickness of the flat sheet 3. A slit 7 is cut in the flat sheet 3 as the draft for its thickness. Then, the flat sheet 3 is bent along the bending lines 4, 5, to form the rising parts 8. Next, the sheet 3 is bent along the bending line 6; hereupon, the bending is smoothly performed because the rising parts 8 do not collide with each other due to the offset equivalent to the thickness between the bending lines 4, 5; hereby, the spot welding can be applied to the welding part 9, and as a result, the angle between the members can be kept at the right angle. Because the spot welding does not cause the sticking of the slag, and single sheet is being bent, the dimensions and angles can be easily turned out.
